[0033] Embodiment 1

[0034] Figure 1 This is a flow chart of an emergency broadcast service data processing method provided by the first embodiment of the present invention. This embodiment is applicable to the case where multiple emergency broadcast audio and corresponding emergency broadcast control instructions are multiplexed at one FM frequency. The method can be executed by an emergency broadcast service data processing device, which can be implemented by software and / or hardware and can generally be integrated in an electronic device, which can be a digital FM emergency broadcast adapter. Figure 1 As shown, the method includes the following operations:

[0035] S110, acquiring emergency broadcast digital audio data and digital FM broadcast control instructions.

[0036] The emergency broadcast digital audio data may be digital audio data that needs to be transmitted through the emergency broadcast system. Exemplarily, the emergency broadcast digital audio data may include but is not limited to alarm audio, emergency broadcast audio, distress signals, and audio data generated by audio programs, etc. As long as it is audio data in digital form that can be transmitted through the application broadcast system, the embodiment of the present invention does not limit the specific data content included in the emergency broadcast digital audio data. The digital FM broadcast control instruction may be a control instruction in the emergency broadcast system for controlling the transmission of emergency broadcast digital audio data.

[0037] In an embodiment of the present invention, a digital FM emergency broadcast adapter can be used to forward and transmit multiple emergency broadcast digital audio data based on one FM frequency, thereby realizing the transmission of multiple digital audio data based on the emergency broadcast system. The digital FM emergency broadcast adapter is an adapter that can forward and transmit emergency broadcast digital audio data in the emergency broadcast system. Accordingly, when forwarding and transmitting multiple emergency broadcast digital audio data based on one FM frequency through a digital FM emergency broadcast adapter, the emergency broadcast digital audio data and the digital FM broadcast control instructions can be first obtained through the digital FM emergency broadcast adapter, thereby determining the data content of the specific digital audio to be played and the corresponding control instructions.

[0038] Optionally, the emergency broadcast digital audio data may be a plurality of different types of digital audio data obtained through different channels, for example, digital audio data corresponding to a plurality of audio programs, etc. Each type of emergency broadcast digital audio data may correspond to a digital FM broadcast control instruction, and each digital FM broadcast control instruction may control the transmission of the corresponding emergency broadcast digital audio data. Alternatively, multiple emergency broadcast digital audio data may correspond to one digital FM broadcast control instruction, and the digital FM broadcast control instruction may include a plurality of control information, and each control information may control the transmission of the corresponding emergency broadcast digital audio data.

[0039] S120: Determine a target multiplexing mode of the emergency broadcast digital audio data and the digital FM broadcast control instruction.

[0040] The target multiplexing mode may be a specific multiplexing mode adopted by the digital FM emergency broadcast adapter for the emergency broadcast digital audio data and the digital FM broadcast control instructions.

[0041] Correspondingly, after the digital FM emergency broadcast adapter obtains the emergency broadcast digital audio data and digital FM broadcast control instructions, it can determine the target multiplexing mode of the emergency broadcast digital audio data and digital FM broadcast control instructions according to corresponding rules, thereby multiplexing the emergency broadcast digital audio data and digital FM broadcast control instructions.

[0042] It should be noted that in the prior art, similar to the FM-RDS mode of the emergency broadcast system, when digital audio data is transmitted through the emergency broadcast system, each frequency point can usually only transmit one channel of digital audio data. When the emergency broadcast needs to transmit multiple audios, it needs to occupy multiple frequency points, which does not efficiently utilize the frequency resources of the emergency broadcast system.

[0043] The embodiment of the present invention utilizes a digital FM emergency broadcast adapter to configure a target multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions in one frequency point, thereby realizing the simultaneous transmission of multiple emergency broadcast digital audio data and corresponding digital FM broadcast control instructions through one frequency point, thereby improving the utilization rate of frequency resources when the emergency broadcast service transmits digital audio data, and further improving the efficiency of the emergency broadcast service in transmitting digital audio data.

[0044] Optionally, the target multiplexing mode may include an independent multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instruction information. Exemplarily, the independent multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instruction may be to use a different service multiplexing frame to multiplex the digital FM broadcast control instruction and N channels of emergency broadcast digital audio data, respectively.

[0045] Alternatively, the target multiplexing mode may also include a centralized multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instruction information. Exemplarily, the centralized multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions may be to multiplex the digital FM broadcast control instructions and N channels of emergency broadcast digital audio data using one or a limited number of service multiplexing frames.

[0046] S130. Multiplexing the emergency broadcast digital audio data and the digital FM broadcast control instruction through the target multiplexing mode.

[0047] In an embodiment of the present invention, after determining the target multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions, the emergency broadcast digital audio data and digital FM broadcast control instructions can be multiplexed through the target multiplexing mode, thereby realizing a transmission method of multiplexing multiple emergency broadcast digital audio data and corresponding digital FM broadcast control instructions through one frequency resource.

[0048] The embodiment of the present invention utilizes a digital FM emergency broadcast adapter to obtain emergency broadcast digital audio data and digital FM broadcast control instructions, and further determines a target multiplexing mode for the emergency broadcast digital audio data and the digital FM broadcast control instructions, thereby multiplexing the emergency broadcast digital audio data and the digital FM broadcast control instructions through the determined target multiplexing mode, thereby solving the problems of low frequency resource utilization and transmission efficiency in audio transmission of existing emergency broadcast services, and can improve the utilization of frequency resources when the emergency broadcast service transmits audio, thereby improving the efficiency of audio transmission of the emergency broadcast service.

[0049] Embodiment 2

[0050] Figure 2This is a flowchart of an emergency broadcast service data processing method provided by the second embodiment of the present invention. This embodiment is specific based on the above embodiment. In this embodiment, a variety of specific optional implementation methods for obtaining emergency broadcast digital audio data and digital FM broadcast control instructions, and multiplexing emergency broadcast digital audio data and digital FM broadcast control instructions through a target multiplexing mode are provided. At the same time, optional implementation operations after multiplexing emergency broadcast digital audio data and digital FM broadcast control instructions are provided. Accordingly, Figure 2 As shown, the method of this embodiment may include:

[0051] S210: Acquire emergency broadcast digital audio data and digital FM broadcast control instructions.

[0052] In an optional embodiment of the present invention, obtaining emergency broadcast digital audio data may include: obtaining original emergency broadcast audio data; wherein the original emergency broadcast audio data includes upper channel audio processing data and / or local audio processing data; encoding and transcoding the original emergency broadcast audio data to obtain the emergency broadcast digital audio data.

[0053] Among them, the original emergency broadcast audio data can be the digital audio data obtained by the digital FM emergency broadcast adapter through at least one channel and processed. The upper channel audio processing data can be the digital audio data obtained by the digital FM emergency broadcast adapter through the external upper channel. Exemplarily, the external upper broadcast channel can include but is not limited to the digital video broadcasting cable (Digital Video Broadcasting Cable, DVBC) channel, the terrestrial digital multimedia broadcasting (Digital Terrestrial Multimedia Broadcast, DTMB) channel, the Internet Protocol (Internet Protocol, IP) channel and the fourth generation mobile communication technology (Fourth Generation, 4G) channel, etc., and the embodiment of the present invention does not limit the specific type of the external upper broadcast channel. The above external upper broadcast channels can belong to different regions, and the broadcast data content can also be different. The local audio processing data can be the digital audio data obtained and processed locally by the digital FM emergency broadcast adapter. Exemplarily, the digital FM emergency broadcast adapter can obtain local audio processing data through various local broadcast channels such as U disk, line input and microphone, and the embodiment of the present invention does not limit the specific content type of the local broadcast channel.

[0054] In an embodiment of the present invention, the digital FM emergency broadcast adapter can obtain the upper channel audio processing data and / or the local audio processing data as the original emergency broadcast audio data. Specifically, if the audio data directly obtained through the upper channel is digital audio, the digital audio data can be directly extracted as the upper channel audio processing data; if the audio data directly obtained through the upper channel is analog audio, the analog audio can be sampled first and converted into digital audio to obtain the upper channel audio processing data. Similarly, if the audio data directly obtained through the local channel is digital audio, the digital audio data can be directly extracted as the local audio processing data; if the audio data directly obtained through the local pipeline is analog audio, the analog audio can be sampled first and converted into digital audio to obtain the local audio processing data. After obtaining the upper channel audio processing data and / or the local audio processing data, the original emergency broadcast audio data in digital form can be encoded and transcoded to obtain data in a coding format that meets the requirements of the digital FM standard.

[0055] In an optional embodiment of the present invention, obtaining digital FM broadcast control instructions may include: extracting the upper-level channel emergency broadcast instructions from the original upper-level channel emergency broadcast instructions, and generating the digital FM broadcast control instructions according to the upper-level channel emergency broadcast instructions; and / or obtaining local audio configuration information input by the user based on the front panel, and generating the digital FM broadcast control instructions according to the local audio configuration information; after obtaining the digital FM broadcast control instructions, it may also include: combining and packaging the digital FM broadcast control instructions.

[0056] Among them, the original upper channel emergency broadcast instruction can be a control instruction originally sent from the external emergency broadcast channel to the digital FM emergency broadcast adapter. The upper channel emergency broadcast instruction can be the instruction information extracted by the digital FM emergency broadcast adapter from the original upper channel emergency broadcast instruction. The digital FM broadcast control instruction can be a set of instructions generated by the digital FM emergency broadcast adapter for managing and controlling the transmission of emergency broadcast digital audio data in the emergency broadcast system. The local audio configuration information can be parameter information related to the playback of emergency broadcast digital audio data configured by the user based on the front panel of the digital FM emergency broadcast adapter.

[0057] In an embodiment of the present invention, if the digital FM emergency broadcast adapter obtains digital audio data through an upper channel, it can also simultaneously receive the original upper channel emergency broadcast instruction issued by the upper channel based on the upper channel emergency broadcast protocol, thereby extracting the upper channel emergency broadcast instruction from the original upper channel emergency broadcast instruction, and generating a digital FM broadcast control instruction according to the extracted upper channel emergency broadcast instruction. If the digital FM emergency broadcast adapter obtains digital audio data through a local pipeline, it can also simultaneously obtain the local audio configuration information input by the user based on the front panel of the digital FM emergency broadcast adapter, so that when playing the local audio data, the digital FM broadcast control instruction is generated according to the local audio configuration information. Usually, since one audio program can correspond to one emergency broadcast ID, one emergency broadcast ID corresponds to one digital FM broadcast control instruction. The digital FM emergency broadcast adapter usually generates multiple digital FM broadcast control instructions. Therefore, after obtaining the digital FM broadcast control instruction, the digital FM emergency broadcast adapter can combine and package each digital FM broadcast control instruction according to the digital FM data format, thereby improving the transmission efficiency of the digital FM broadcast control instruction.

[0058] In an optional embodiment of the present invention, the generation of the digital FM broadcast control instruction may include: obtaining the emergency broadcast ID, start and end time, broadcast type and level, broadcast target device number list and broadcast audio data identification information of the digital FM broadcast control instruction; assigning values ​​to corresponding fields of the digital FM broadcast control instruction according to the emergency broadcast ID, start and end time, broadcast type and level, broadcast target device number list and broadcast audio data identification information to obtain the digital FM broadcast control instruction; wherein the broadcast audio data identification information may include a service multiplexing frame identifier and a multiplexing subframe sequence number of the audio data.

[0059] Among them, the emergency broadcast ID can be an identifier for identifying specific emergency broadcast digital audio data, and the emergency broadcast system can quickly locate and start the relevant emergency broadcast digital audio data through the emergency broadcast ID. The start and end time can be the specific time points when the emergency broadcast digital audio data starts and ends playing, which can ensure that the emergency broadcast digital audio data is played within a predetermined time range. The broadcast type can be a specific content type of the emergency broadcast digital audio data, such as news audio, music audio, or emergency notification audio; the level can be the priority or importance level of the emergency broadcast digital audio data playback, for example, the emergency notification audio may have a high priority to ensure its priority transmission. The broadcast device number and list can be a series of numbers representing specific devices or device groups that receive emergency broadcast digital audio data. The broadcast audio data identification information can be used to identify the information transmitted by the digital audio data content in the emergency broadcast system, for example, it can include but is not limited to the service multiplexing frame identifier and multiplexing subframe sequence number of the audio data. The service multiplexing frame identifier can be used to identify the service multiplexing frame that transmits the corresponding digital audio data. The multiplexing subframe sequence number can be used to identify the multiplexing subframe that multiplexes the corresponding digital audio data.

[0060] It can be understood that the emergency broadcast system can transmit multiple emergency broadcast digital audio data through service multiplexing frames. The service multiplexing frame is a multiplexing frame used to encapsulate service information. Each service multiplexing frame may include multiple multiplexing subframes, and the multiplexing subframe is used to carry services. A multiplexing subframe can only carry data for one service, and the data for one service can be transmitted in one or more multiplexing subframes. Optionally, in an embodiment of the present invention, the multiplexing subframe used for multiplexing emergency broadcast digital audio data may be composed of a subframe header, an audio segment, and content to be filled; the multiplexing subframe used for multiplexing digital FM broadcast control instructions may be composed of a subframe header, a data segment, and content to be filled.

[0061] Specifically, whether generating digital FM broadcast control instructions based on the emergency broadcast instructions of the upper-level channel or generating digital FM broadcast control instructions based on local audio configuration information, it is necessary to extract the key information required to generate the digital FM broadcast control instructions from the emergency broadcast instructions of the upper-level channel and / or the local audio configuration information, namely, the emergency broadcast ID, start and end time, broadcast type and level, broadcast target device number list, corresponding audio data service multiplexing frame identifier and multiplexing subframe sequence number and other information, and then assign values ​​to the fields corresponding to the digital FM broadcast control instructions according to the above-extracted information to generate the final required digital FM broadcast control instructions.

[0062] S220: Determine a target multiplexing mode of the emergency broadcast digital audio data and the digital FM broadcast control instruction.

[0063] S230. Determine the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction according to the target multiplexing mode.

[0064] The service multiplexing frame may include a service multiplexing frame header and a service multiplexing payload. Figure 3 is a schematic diagram of a service multiplexing frame payload structure provided by Embodiment 2 of the present invention. In a specific example, Figure 3 As shown, the service multiplexing payload can be composed of one or more multiplexing subframes, which does not exceed the preset threshold of the multiplexing subframe. For example, the preset threshold can be 15, etc. The multiplexing subframes are placed in the service multiplexing frame in sequence.

[0065] In an embodiment of the present invention, after determining the target multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions, the emergency broadcast digital audio data and digital FM broadcast control instructions can be multiplexed in the multiplexing subframe according to the specific multiplexing method specified in the target multiplexing mode, thereby obtaining the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and digital FM broadcast control instructions.

[0066] In an optional embodiment of the present invention, determining the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction according to the target multiplexing mode may include: determining the number of target service multiplexing frames according to the number of the emergency broadcast digital audio data and the digital FM broadcast control instructions; wherein each of the target service multiplexing frames includes a multiplexing subframe; and obtaining the service multiplexing payload structure of the service multiplexing frame by multiplexing each of the emergency broadcast digital audio data and the digital FM broadcast control instruction through the multiplexing subframes of each of the target service multiplexing frames.

[0067] The target service multiplexing frame may be a service multiplexing frame required by the emergency broadcasting system for multiplexing emergency broadcasting digital audio data and digital FM broadcasting control instructions.

[0068] In an embodiment of the present invention, the target multiplexing mode can be an independent multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions. That is, the number of target service multiplexing frames can be determined according to the number of emergency broadcast digital audio data and digital FM broadcast control instructions, and the target service multiplexing frame can use a multiplexing subframe to multiplex the emergency broadcast digital audio data or digital FM broadcast control instructions, so that each emergency broadcast digital audio data and digital FM broadcast control instruction are multiplexed respectively through the multiplexing subframes of each target service multiplexing frame, thereby obtaining the service multiplexing payload structure of the service multiplexing frame.

[0069] Exemplarily, assuming that it includes 1 digital FM broadcast control instruction, the digital FM broadcast control instruction is a combined and packaged control instruction, which can include information of multiple different digital FM broadcast control instructions, and multiple emergency broadcast digital audio data, such as emergency broadcast digital audio data 1, emergency broadcast digital audio data 2 and emergency broadcast digital audio data 3. Then, the number of emergency broadcast digital audio data and the digital FM broadcast control instruction determines that the number of target service multiplexing frames is 4. Therefore, 4 service multiplexing frames can be determined, namely service multiplexing frame 1, service multiplexing frame 2, service multiplexing frame 3 and service multiplexing frame 4. Further, the digital FM broadcast control instruction can be multiplexed through the multiplexing subframe of service multiplexing frame 1, the emergency broadcast digital audio data 1 can be multiplexed through the multiplexing subframe of service multiplexing frame 2, the emergency broadcast digital audio data 2 can be multiplexed through the multiplexing subframe of service multiplexing frame 3, and the emergency broadcast digital audio data 3 can be multiplexed through the multiplexing subframe of service multiplexing frame 4.

[0070] In an optional embodiment of the present invention, the business multiplexing payload structure of the business multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction is determined according to the target multiplexing mode, and may include: determining a target business multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction when it is determined that the sum of the number of the emergency broadcast digital audio data and the number of the digital FM broadcast control instructions is less than or equal to the set multiplexing sub-frame number threshold; the number of multiplexing sub-frames included in the target business multiplexing frame is less than or equal to the set multiplexing sub-frame number threshold; and obtaining the business multiplexing payload structure of the business multiplexing frame by multiplexing each of the emergency broadcast digital audio data and the digital FM broadcast control instruction through each multiplexing sub-frame of the target business multiplexing frame.

[0071] The multiplexing subframe number threshold may be a predefined maximum number of multiplexing subframes that can be included. Exemplarily, the multiplexing subframe number threshold may be 15, and the embodiment of the present invention does not specifically limit the multiplexing subframe number threshold.

[0072] In an embodiment of the present invention, the target multiplexing mode can also be a centralized multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions. The centralized multiplexing mode can also have two different multiplexing scenarios. Specifically, before multiplexing the emergency broadcast audio data and the digital FM broadcast control instructions using the centralized multiplexing mode, it can be first determined whether the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions exceeds the maximum number of multiplexing subframes that can be included in a target service multiplexing frame. If it is determined that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions is less than or equal to the set multiplexing subframe number threshold, it indicates that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions does not exceed the maximum number of multiplexing subframes that can be included in a target service multiplexing frame. At this time, only a corresponding target service multiplexing frame can be configured for the emergency broadcast digital audio data and the digital FM broadcast control instructions, and each emergency broadcast digital audio data and digital FM broadcast control instruction are multiplexed through each multiplexing subframe of the target service multiplexing frame, thereby obtaining a service multiplexing payload structure of the service multiplexing frame. That is, the digital FM broadcast control instructions and N-channel emergency broadcast digital audio data are multiplexed through each multiplexing subframe of a target service multiplexing frame.

[0073] Exemplarily, assuming that the number of emergency broadcast digital audio data is 3, the number of digital FM broadcast control instructions is 1, and the threshold value of the number of multiplexed subframes is 15, accordingly, the digital FM broadcast control instructions can be multiplexed through multiplexed subframe 1 in service multiplexed frame 1, the emergency broadcast digital audio data 1 can be multiplexed through multiplexed subframe 2 in service multiplexed frame 1, the emergency broadcast digital audio data 2 can be multiplexed through multiplexed subframe 3 in service multiplexed frame 1, and the emergency broadcast digital audio data 3 can be multiplexed through multiplexed subframe 4 in service multiplexed frame 1. It can be understood that when a service multiplexed frame is used to multiplex the number of emergency broadcast digital audio data and digital FM broadcast control instructions in a centralized multiplexing manner, the number of multiplexed subframes included in the target service multiplexed frame is less than or equal to the set multiplexed subframe number threshold.

[0074] In an optional embodiment of the present invention, determining the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction according to the target multiplexing mode may include: determining multiple target service multiplexing frames corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction when it is determined that the sum of the number of the emergency broadcast digital audio data and the number of the digital FM broadcast control instructions is greater than a set multiplexing subframe number threshold; the number of multiplexing subframes included in the target service multiplexing frame is less than or equal to the set multiplexing subframe number threshold; and obtaining the service multiplexing payload structure of the service multiplexing frame by multiplexing subframes of each of the emergency broadcast digital audio data and the digital FM broadcast control instruction.

[0075] In an embodiment of the present invention, when the centralized multiplexing mode is used to multiplex the emergency broadcast digital audio data and the digital FM broadcast control instructions, if it is determined that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions is greater than the set multiplexing subframe number threshold, it indicates that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions exceeds the maximum number of multiplexing subframes that can be included in a target service multiplexing frame. Therefore, it is necessary to configure corresponding multiple target service multiplexing frames for the emergency broadcast digital audio data and the digital FM broadcast control instructions, and multiplex each emergency broadcast digital audio data and digital FM broadcast control instruction through each multiplexing subframe of the multiple target service multiplexing frames, thereby obtaining a service multiplexing payload structure of the service multiplexing frame. For example, assuming that the number of emergency broadcast digital audio data is 16, the number of digital FM broadcast control instructions is 1, the multiplexing subframe number threshold is 15, and the number of multiplexing subframes included in the target service multiplexing frame is 15, accordingly, the digital FM broadcast control instruction can be multiplexed through multiplexing subframe 1 in service multiplexing frame 1, the emergency broadcast digital audio data 1 can be multiplexed through multiplexing subframe 2 in service multiplexing frame 1, the emergency broadcast digital audio data 2 can be multiplexed through multiplexing subframe 3 in service multiplexing frame 1, and the emergency broadcast digital audio data 3 can be multiplexed through multiplexing subframe 4 in service multiplexing frame 1, and so on, emergency broadcast digital audio data 14 can be multiplexed through multiplexing subframe 15 in service multiplexing frame 1, emergency broadcast digital audio data 15 can be multiplexed through multiplexing subframe 1 of service multiplexing frame 2, and emergency broadcast digital audio data 16 can be multiplexed through multiplexing subframe 2 of service multiplexing frame 2. It can be understood that when multiple service multiplexing frames are used to multiplex the number of emergency broadcast digital audio data and digital FM broadcast control instructions through centralized multiplexing, the number of multiplexing subframes included in the target service multiplexing frame is less than or equal to the set multiplexing subframe number threshold.

[0076] S240: Generate a service multiplexing frame header of the service multiplexing frame according to the service multiplexing frame identifier and the multiplexing subframe information.

[0077] The multiplexing subframe information may be related information of the multiplexing subframe carrying the emergency broadcast digital audio data and the digital FM broadcast control instructions, for example, including but not limited to the number of multiplexing subframes and the length of the multiplexing subframes, etc. The service multiplexing frame header may be the frame header of the service multiplexing frame, which may be used to organize and manage the control information of the service multiplexing frame.

[0078] Accordingly, after determining the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction, the service multiplexing frame header of the service multiplexing frame can be generated by combining the service multiplexing frame identifier, the number of multiplexing subframes, the length of multiplexing subframes and other multiplexing subframe information. Table 1 is a service multiplexing frame header parameter list provided in the second embodiment of the present invention.

[0087]

[0088] In the embodiment of the present invention, after obtaining the service multiplexing configuration table and the associated target data table corresponding to the service multiplexing frame, a control information table is generated according to the service multiplexing configuration table and the associated target data table.

[0090] Among them, the control multiplexing frame is a multiplexing frame used to encapsulate control information.

[0091] In the embodiment of the present invention, after the control information table is generated according to the service multiplexing configuration table and the associated target data table, a control multiplexing frame can be generated according to the control information table, thereby ensuring that the transmission data can be correctly identified and decoded. Among them, the control multiplexing frame can include a control multiplexing frame header and a control multiplexing frame payload, and the control multiplexing frame payload can be composed of one or more control information tables, which are sequentially encapsulated in the control multiplexing frame, that is, the control multiplexing frame can be generated according to the control information table.

The modulation method may be but is not limited to orthogonal frequency division multiplexing (OFDM), and the present invention does not limit the specific method of modulation.

[0094] In an embodiment of the present invention, channel coding and modulation processing are performed on the service multiplexing frame and the control multiplexing frame to obtain a digital FM modulation signal, thereby further improving the efficiency of transmission of emergency broadcast digital audio data and digital FM broadcast control instructions in the channel.

[0095] S280: Send the digital FM modulation signal to a digital FM emergency broadcast terminal.

[0096] Among them, the digital FM emergency broadcast terminal can be a special device for receiving and playing emergency broadcast digital audio data, which can include but is not limited to speakers, radios, televisions, and display screens.

[0097] In an embodiment of the present invention, after the service multiplexing frame and the control multiplexing frame are channel-coded and modulated to obtain a digital FM modulated signal, the digital FM modulated signal can be sent to the digital FM emergency broadcast terminal. Exemplarily, if the communication distance between the digital FM emergency broadcast adapter and the digital FM emergency broadcast terminal is far, the channel-coded data can be OFDM modulated, and the modulated signal can be output to the FM transmitter, which then further sends the signal to the digital FM emergency broadcast terminal. If the communication distance between the digital FM emergency broadcast adapter and the digital FM emergency broadcast terminal is short, the digital FM emergency broadcast adapter can directly send the modulated signal to the digital FM emergency broadcast terminal.

[0098] In an embodiment of the present invention, the emergency broadcast digital audio data and the digital FM broadcast control instructions are obtained by using a digital FM emergency broadcast adapter, and the emergency broadcast digital audio data and the digital FM broadcast control instructions are multiplexed through a variety of specific optional target multiplexing modes.

At the same time, a control multiplexing frame encapsulating the control information is generated, and then the service multiplexing frame and the control multiplexing frame are sent to the digital FM emergency broadcast terminal at the same time, so that the digital FM emergency broadcast terminal can obtain the corresponding digital audio data based on the service multiplexing frame and the control multiplexing frame for playback. The above technical scheme can solve the problems of low frequency resource utilization and transmission efficiency when the existing emergency broadcast service transmits audio, and can improve the utilization of frequency resources when the emergency broadcast service transmits audio, thereby improving the efficiency of the emergency broadcast service in transmitting audio.

[0102] Step 2: Parse the emergency broadcast command of the upper channel. The control command here may contain multiple channels.

[0103] Step 3: Convert the emergency broadcast command of the upper channel into a digital FM broadcast control command.

[0109] The embodiment of the present invention also provides a local channel emergency broadcast service data processing method, Figure 5 is a flow chart of a local channel emergency broadcast service data processing method provided by Embodiment 2 of the present invention. In a specific example, Figure 5 As shown, the process of processing the local channel emergency broadcast service data by the digital FM emergency broadcast adapter may include the following steps:

[0110] Step 1: Play and obtain local audio processing data.

[0111] Step 2: Obtain local audio configuration information input by the user based on the front panel, and generate a digital FM broadcast control instruction according to the local audio configuration information.

[0112] Step 3: Get the local audio and determine whether it needs to be encoded or transcoded to meet the digital audio requirements. If necessary, encode or transcode the audio; otherwise, directly enter the multiplexing module.

[0113] Step 4: Multiplexing the digital FM broadcast control instructions and the multi-channel emergency broadcast digital audio data.

[0114] Step 5: The multiplexed data is channel coded and modulated.

[0115] Step 6: Send the modulated signal.

[0116] In an embodiment of the present invention, by utilizing a digital FM emergency broadcast adapter to obtain emergency broadcast digital audio data and digital FM broadcast control instructions, the target multiplexing mode of the emergency broadcast digital audio data and the digital FM broadcast control instructions is further determined, thereby multiplexing the emergency broadcast digital audio data and the digital FM broadcast control instructions through the determined target multiplexing mode, and channel encoding and modulating the multiplexed data, and then forwarding the modulated signal. The problems of low frequency resource utilization and transmission efficiency in the existing emergency broadcast service when transmitting audio can be solved, which can improve the utilization of frequency resources when the emergency broadcast service transmits audio, thereby improving the efficiency of audio transmission by the emergency broadcast service.

[0117] Embodiment 3

[0118] Figure 6 is a schematic diagram of a digital FM emergency broadcast adapter provided by Embodiment 3 of the present invention, such as Figure 6 As shown, the FM emergency broadcast adapter includes: a data instruction receiving module 310 and a main control module 320, the data instruction receiving module 310 and the main control module 320 are communicatively connected, wherein:

[0119] The data instruction receiving module 310 is used to obtain emergency broadcast digital audio data and digital FM broadcast control instructions.

[0120] The main control module 320 is used to determine the target multiplexing mode of the emergency broadcast digital audio data and the digital FM broadcast control instruction; and multiplex the emergency broadcast digital audio data and the digital FM broadcast control instruction according to the target multiplexing mode.

[0121] Optionally, the data instruction receiving module 310 is specifically used to: obtain original emergency broadcast audio data; wherein the original emergency broadcast audio data includes upper channel audio processing data and / or local audio processing data; encode and transcode the original emergency broadcast audio data to obtain the emergency broadcast audio data.

[0122] Figure 7 is a structural diagram of a digital FM emergency broadcast adapter provided by Embodiment 3 of the present invention, Figure 8 FIG. 1 is a working logic diagram of a digital FM emergency broadcast adapter provided by Embodiment 3 of the present invention. Figure 7 and Figure 8As shown, the data instruction receiving module 310 may include an upper-level channel signal receiving module and / or a local audio broadcasting module. Specifically, the upper-level channel signal receiving module may receive and obtain the audio data sent by the upper-level channel, and the local audio broadcasting module may receive and obtain the audio data sent by the local channel. Further, when the upper-level channel signal receiving module and / or the local audio broadcasting module determine that the received audio data is analog audio, it performs analog-to-digital conversion processing to obtain digital audio data such as upper-level channel audio processing data and / or local audio processing data, and then sends the upper-level channel audio processing data and / or local audio processing data to the main control module 320. When the upper-level channel signal receiving module and / or the local audio broadcasting module determine that the received audio data is digital audio, it may directly extract and obtain digital audio data such as upper-level channel audio processing data and / or local audio processing data, and then send the upper-level channel audio processing data and / or local audio processing data to the main control module 320. The main control module 320 performs encoding and transcoding processing according to the received upper channel audio processing data and / or local audio processing data, thereby obtaining data in a coding format that meets the requirements of the digital frequency modulation standard.

[0123] Optionally, the data instruction receiving module 310 is also used to: extract the upper-level channel emergency broadcast instruction from the original upper-level channel emergency broadcast instruction, and generate the digital FM broadcast control instruction according to the upper-level channel emergency broadcast instruction; and / or obtain local audio configuration information input by the user based on the front panel, and generate the digital FM broadcast control instruction according to the local audio configuration information; after obtaining the digital FM broadcast control instruction, it also includes: combining and packaging the digital FM broadcast control instruction.

[0124] In the embodiment of the present invention, Figure 7 and Figure 8As shown, if the digital FM emergency broadcast adapter obtains digital audio data through the upper channel signal receiving module, it can also simultaneously receive the original upper channel emergency broadcast instruction issued by the upper channel based on the upper channel emergency broadcast protocol through the upper channel signal receiving module, thereby extracting the upper channel emergency broadcast instruction from the original upper channel emergency broadcast instruction, and generating a digital FM broadcast control instruction according to the extracted upper channel emergency broadcast instruction. If the digital FM emergency broadcast adapter obtains digital audio data through the local audio broadcast module, it can also simultaneously obtain the local audio configuration information input by the user based on the front panel of the digital FM emergency broadcast adapter, so that when playing the local audio data, the digital FM broadcast control instruction is generated according to the local audio configuration information. Usually, since one audio program can correspond to one emergency broadcast ID, one emergency broadcast ID corresponds to one digital FM broadcast control instruction. The digital FM emergency broadcast adapter usually generates multiple digital FM broadcast control instructions. Therefore, after obtaining the digital FM broadcast control instruction, the digital FM emergency broadcast adapter can combine and package each digital FM broadcast control instruction according to the digital FM data format, thereby improving the transmission efficiency of the digital FM broadcast control instruction.

[0125] Optionally, the data instruction receiving module 310 is also used to: obtain the emergency broadcast ID, start and end time, broadcast type and level, broadcast target device number list and broadcast audio data identification information of the digital FM broadcast control instruction; assign values ​​to corresponding fields of the digital FM broadcast control instruction according to the emergency broadcast ID, start and end time, broadcast type and level, broadcast target device number list and broadcast audio data identification information to obtain the digital FM broadcast control instruction; wherein the broadcast audio data identification information includes the service multiplexing frame identifier and multiplexing subframe sequence number of the audio data.

[0126] Specifically, in the data instruction receiving module 310, whether generating a digital FM broadcast control instruction through the upper-level channel signal receiving module according to the upper-level channel emergency broadcast instruction, or generating a digital FM broadcast control instruction through the local audio broadcast module according to the local audio configuration information, it is necessary to extract the key information required to generate the digital FM broadcast control instruction from the upper-level channel emergency broadcast instruction and / or the local audio configuration information, namely, the emergency broadcast ID, start and end time, broadcast type and level, broadcast target device number list, corresponding audio data service multiplexing frame identifier and multiplexing subframe sequence number and other information, and then assign values ​​to the fields corresponding to the digital FM broadcast control instruction according to the above-extracted information to generate the final required digital FM broadcast control instruction.

[0127] Optionally, the main control module 320 is specifically used to: determine the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instruction according to the target multiplexing mode; and generate a service multiplexing frame header of the service multiplexing frame according to the service multiplexing frame identifier and multiplexing subframe information.

[0128] like Figure 7 and Figure 8 As shown, the main control module 320 can be used to complete functions such as receiving emergency broadcast instructions from the upper channel, decoding the audio processing data of the upper channel, encoding the emergency broadcast digital audio data, generating digital FM broadcast control instructions (including upper and local), and multiplexing digital FM data.

[0129] In a specific example, in the main control module 320, after determining the target multiplexing mode of the emergency broadcast digital audio data and the digital FM broadcast control instructions, the emergency broadcast digital audio data and the digital FM broadcast control instructions can be multiplexed in the multiplexing subframe according to the specific multiplexing method specified in the target multiplexing mode, thereby obtaining the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instructions. Accordingly, after determining the service multiplexing payload structure of the service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instructions, the service multiplexing frame header of the service multiplexing frame can be generated by combining the service multiplexing frame identifier and the multiplexing subframe number and multiplexing subframe length and other multiplexing subframe information. Further, the service multiplexing frame header and the service multiplexing payload structure can be combined to obtain the service multiplexing frame finally used for transmission.

[0130] Optionally, the main control module 320 is also used to: determine the number of target service multiplexing frames according to the number of the emergency broadcast digital audio data and the digital FM broadcast control instructions; wherein each target service multiplexing frame includes a multiplexing subframe; and obtain the service multiplexing payload structure of the service multiplexing frame by multiplexing each of the emergency broadcast digital audio data and the digital FM broadcast control instructions through the multiplexing subframes of each target service multiplexing frame.

[0131] In the embodiment of the present invention, in the main control module 320, the target multiplexing mode can be an independent multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions. That is, the number of target service multiplexing frames can be determined according to the number of emergency broadcast digital audio data and digital FM broadcast control instructions, and the target service multiplexing frame can use a multiplexing subframe to multiplex the emergency broadcast digital audio data or digital FM broadcast control instructions, so that each emergency broadcast digital audio data and digital FM broadcast control instruction are multiplexed respectively through the multiplexing subframes of each target service multiplexing frame, thereby obtaining the service multiplexing payload structure of the service multiplexing frame.

[0132] Optionally, the main control module 320 is also used to: when it is determined that the sum of the number of the emergency broadcast digital audio data and the number of the digital FM broadcast control instructions is less than or equal to a set multiplexing subframe number threshold, determine a target service multiplexing frame corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instructions; the number of multiplexing subframes included in the target service multiplexing frame is less than or equal to the set multiplexing subframe number threshold; and each of the emergency broadcast digital audio data and the digital FM broadcast control instructions are multiplexed through each multiplexing subframe of the target service multiplexing frame to obtain a service multiplexing payload structure of the service multiplexing frame.

[0133] In an embodiment of the present invention, in the main control module 320, the target multiplexing mode can also be a centralized multiplexing mode of emergency broadcast digital audio data and digital FM broadcast control instructions. The centralized multiplexing mode can also have two different multiplexing scenarios. Specifically, before the centralized multiplexing mode is used to multiplex the emergency broadcast audio data and the digital FM broadcast control instructions, it can be first determined whether the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions exceeds the maximum number of multiplexing subframes that can be included in a target service multiplexing frame. If it is determined that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions is less than or equal to the set multiplexing subframe number threshold, it indicates that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions does not exceed the maximum number of multiplexing subframes that can be included in a target service multiplexing frame. At this time, only a corresponding target service multiplexing frame can be configured for the emergency broadcast digital audio data and the digital FM broadcast control instruction, and each emergency broadcast digital audio data and digital FM broadcast control instruction are multiplexed through each multiplexing subframe of the target service multiplexing frame, thereby obtaining the service multiplexing payload structure of the service multiplexing frame. That is, the digital FM broadcast control instructions and N-channel emergency broadcast digital audio data are multiplexed through each multiplexing subframe of a target service multiplexing frame.

[0134] Optionally, the main control module 320 is also used to: when it is determined that the sum of the number of the emergency broadcast digital audio data and the number of the digital FM broadcast control instructions is greater than a set multiplexing subframe number threshold, determine a plurality of target service multiplexing frames corresponding to the emergency broadcast digital audio data and the digital FM broadcast control instructions; the number of multiplexing subframes included in the target service multiplexing frame is less than or equal to the set multiplexing subframe number threshold; and multiplex each of the emergency broadcast digital audio data and the digital FM broadcast control instructions through each multiplexing subframe of the plurality of target service multiplexing frames to obtain a service multiplexing payload structure of the service multiplexing frame.

[0135] In an embodiment of the present invention, if it is determined that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions is greater than the set multiplexing subframe number threshold, it indicates that the sum of the number of emergency broadcast digital audio data and the number of digital FM broadcast control instructions exceeds the maximum number of multiplexing subframes that can be included in a target service multiplexing frame. Therefore, it is necessary to configure corresponding multiple target service multiplexing frames for the emergency broadcast digital audio data and the digital FM broadcast control instructions, and multiplex each emergency broadcast digital audio data and digital FM broadcast control instruction through each multiplexing subframe of the multiple target service multiplexing frames, thereby obtaining a service multiplexing payload structure of the service multiplexing frame.

[0136] Optionally, after the main control module 320, it is also used to: determine the target upper-level channel audio processing data according to the upper-level channel priority; and monitor the forwarding and playing data of the target upper-level channel audio processing data and / or the local audio processing data.

[0137] For example, Figure 7 and Figure 8 As shown, the digital FM emergency broadcast adapter can also be provided with a monitoring speaker to monitor the forwarded emergency broadcast digital audio data through the monitoring speaker to ensure that the emergency broadcast digital audio data is successfully forwarded. Specifically, the digital FM emergency broadcast adapter can determine the upper-level channel audio processing data with the highest priority as the target upper-level channel audio processing data according to the upper-level channel priority, and monitor the forwarded playback data of the target upper-level channel audio processing data and / or the local audio processing data, and determine whether the forwarding playback of the target upper-level channel audio processing data and / or the local audio processing data is successful according to the monitoring results.

[0138] Optionally, the main control module 320 is further used to: obtain a service multiplexing configuration table and an associated target data table corresponding to a service multiplexing frame; generate a control information table according to the service multiplexing configuration table and the associated target data table; and generate a control multiplexing frame according to the control information table.

[0139] In the embodiment of the present invention, the main control module 320 can also obtain the service multiplexing configuration table and the associated target data table corresponding to the service multiplexing frame, generate a control information table according to the service multiplexing configuration table and the associated target data table, and then generate a control multiplexing frame according to the control information table. Among them, the control multiplexing frame may include a control multiplexing frame header and a control multiplexing frame payload; the control multiplexing frame payload is composed of one or more control information tables, which are sequentially encapsulated in the control multiplexing frame, that is, the control multiplexing frame can be generated according to the control information table.

[0140] Optionally, the digital FM emergency broadcast adapter may also be provided with a digital FM sending module, which is used to: perform channel coding and modulation processing on the service multiplexing frame and the control multiplexing frame to obtain a digital FM modulation signal; and send the digital FM modulation signal to the digital FM emergency broadcast terminal.

[0141] like Figure 7 and Figure 8 As shown, in an embodiment of the present invention, the digital FM emergency broadcast adapter can channel encode and modulate the service multiplexing frames and control multiplexing frames generated by the main control module through the digital FM sending module, thereby obtaining a digital FM modulated signal, further improving the efficiency of the transmission of emergency broadcast digital audio data and digital FM broadcast control instructions in the channel. If the communication distance between the digital FM emergency broadcast adapter and the digital FM emergency broadcast terminal is far, the channel-encoded data can be modulated, and the modulated signal is output to the FM transmitter, and the FM transmitter further sends the signal to the digital FM emergency broadcast terminal. If the communication distance between the digital FM emergency broadcast adapter and the digital FM emergency broadcast terminal is short, the modulated signal can be directly sent to the digital FM emergency broadcast terminal by the digital FM emergency broadcast adapter.

[0142] In the embodiment of the present invention, the data instruction receiving module in the digital FM emergency broadcast adapter obtains the emergency broadcast digital audio data and the digital FM broadcast control instructions by using the digital FM emergency broadcast adapter, and further determines the target multiplexing mode of the emergency broadcast digital audio data and the digital FM broadcast control instructions through the main control module, so that the emergency broadcast digital audio data and the digital FM broadcast control instructions are multiplexed through the determined target multiplexing mode. The problems of low frequency resource utilization and transmission efficiency in the existing emergency broadcast service when transmitting audio can be improved, and the utilization rate of frequency resources when the emergency broadcast service transmits audio can be improved, thereby improving the efficiency of audio transmission by the emergency broadcast service.

[0143] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information are in compliance with the relevant laws and regulations and do not violate public order and good morals.

[0144] It should be noted that any arrangement and combination of the technical features in the above embodiments also falls within the protection scope of the present invention.
