[0019] It should be noted that existing upgrade methods for terrestrial digital multimedia receiving terminals have many inconveniences.

Wired upgrades require the installation of additional cables, which is not only inconvenient for installation and maintenance but may also be subject to environmental limitations. Furthermore, for large multimedia terminal devices with a wide distribution and a large number of devices, using wired upgrades will face a huge workload and high costs.

[0020] Based on this, this utility model embodiment provides a communication system for application upgrades. Figure 1 This utility model provides an architecture diagram of a communication system for application upgrades. This embodiment is applicable to upgrading applications in terrestrial digital multimedia receiving terminals. Figure 1As shown, the communication system 1 for application upgrades includes: a broadcast signal transmitter 1 and a broadcast signal transmission tower 2; the broadcast signal transmitter 1 includes: a transmitter 11 and at least one server, each server being connected to the transmitter 11 via a multiplexer 12, and the transmitter 11 being connected to the broadcast signal transmission tower 2 via a feeder 13; a first server 14 among the servers is used to transmit application upgrade data of at least one application to the multiplexer 12; a second server 15 among the servers is used to transmit audio and video data to the multiplexer 12; the multiplexer 12 is used to combine at least one application upgrade data with audio and video data and transmit it to the transmitter 11; the transmitter 11 is used to transmit the received combined data to the broadcast signal transmission tower 2 via the feeder 13; the broadcast signal transmission tower 2 is used to transmit the combined data to the application terminal 3 via broadcast, so that the application terminal 3 can obtain application upgrade data from the combined data and perform application upgrades.

[0021] The first server 14 can be understood as a server for managing application upgrade data. Specifically, it can be used to acquire application upgrade data and encapsulate it into a bitstream. Optionally, the encapsulated bitstream data stream conforms to the requirements of the terrestrial digital multimedia broadcasting standard. The second server 15 can be considered as a server for managing regular program streams, Program Specific Information (PSI), and Service Information (SI). The application terminal 3 can be understood as a digital multimedia receiving terminal capable of receiving broadcast signals. Optionally, the merged data is transmitted to the application terminal 3 via terrestrial digital multimedia broadcasting.

[0022] In this embodiment, the first server 14 encapsulates the acquired application upgrade data into a bitstream and transmits the bitstream to the multiplexer 12. The second server 15 inserts an upgrade identifier into the Service Group Association (BAT) table and Network Information Table (NIT) of the PSI / SI information table using the PSI / SI editor. The upgrade identifier includes the identifier of each application terminal manufacturer and the Packet Identifier (PID) value used for the application upgrade data. The PSI / SI information table with the inserted upgrade identifier is embedded into the regular program stream containing audio and video data, and the regular program stream is transmitted to the multiplexer 12. In the multiplexer 12, the application upgrade data and audio and video data are merged, and the PID value of the regular program stream containing audio and video data is multiplexed and transmitted with the PID value of the bitstream containing application upgrade data, and correctly associated through the Program Map (PMT) table to ensure that the application terminal 3 can correctly identify the application upgrade data. The multiplexer 12 transmits the combined data to the transmitter 11. The transmitter 11 modulates the received combined data and transmits the modulated combined data to the broadcast signal transmission tower 2 through the feed tube 13. The broadcast signal transmission tower 2 then transmits the combined data to the application terminal 3 via broadcast, so that the application terminal 3 can obtain the combined data through its built-in or external antenna. By parsing the combined data, the application upgrade data is obtained to upgrade the application terminal 3.

[0023] It is understandable that the application upgrade data obtained by the first server 14 is formulated by various manufacturers based on the existing application data version of the application terminal 3 and has been tested to ensure the compatibility and stability of the application upgrade data, so as to avoid version rollback and application upgrade errors.

[0024] This utility model provides a communication system for application upgrades, including a broadcast signal transmitter 1 and a broadcast signal tower 2. The broadcast signal transmitter 1 includes a transmitter 11 and at least one server. Each server is connected to the transmitter 11 via a multiplexer 12, and the transmitter 11 is connected to the broadcast signal tower 2 via a feeder 13. A first server 14 is used to transmit application upgrade data of at least one application to the multiplexer 12. A second server 15 is used to transmit audio and video data to the multiplexer 12. The multiplexer 12 is used to combine at least one application upgrade data with audio and video data and transmit it to the transmitter 11. The transmitter 11 is used to transmit the received combined data to the broadcast signal tower 2 via the feeder 13. The broadcast signal tower 2 is used to transmit the combined data to the application terminal 3 via broadcast, so that the application terminal 3 can obtain application upgrade data from the combined data and perform application upgrades. By connecting the first server 14 and the second server 15 to the transmitter 11 via the multiplexer 12, and connecting the transmitter 11 to the broadcast signal transmission tower 2 via the feeder 13, application upgrade data can be transmitted in batches to the application terminal 3 via broadcast. This allows for automatic and large-scale upgrades of the application terminal 3 without the need for additional equipment or cables.

[0025] As a first optional embodiment of this embodiment, based on the above embodiment, the first server 14 is an upgrade data management server, the upgrade data management server includes: a digital signal transmission interface card, through the transmission interface of the digital signal transmission interface card, at least one application upgrade data is transmitted to the multiplexer 12 in digital signal;

[0026] The second server 15 is a transport stream content editing server, which includes a digital signal broadcasting board. Audio and video data are transmitted to the multiplexer 12 as digital signals through the transmission interface in the digital signal broadcasting board.

[0027] In this embodiment, the first server 14 is an upgrade data management server, used to acquire application upgrade data, encapsulate the application upgrade data into a bitstream, and transmit the bitstream to the multiplexer 12. The upgrade data management server transmits at least one application upgrade data to the multiplexer 12 in digital signal (bitstream) format through the transmission interface (such as the ASI output interface) of the digital signal transmission interface card. The second server 15 is a transport stream content editing server, which includes a digital signal broadcasting board, used to insert upgrade identifiers into the Service Group Association Table (BAT) and Network Information Table (NIT) of the PSI / SI information table through the PSI / SI editor, and embed the PSI / SI information table with the inserted upgrade identifiers into the digital signal (regular program stream) containing audio and video data, and transmit the digital signal to the multiplexer 12 through the transmission interface (such as the ASI output interface) in the digital signal broadcasting board.

[0028] As a second optional embodiment of this example, the multiplexer 12 includes at least two digital signal input interfaces; it receives application upgrade data input by the first server 14 through at least one digital signal input interface; and it receives audio and video data input by the second server 15 through at least one digital signal input interface.

[0029] In this embodiment, the multiplexer 12 includes at least two digital signal input interfaces (such as ASI input interfaces), which are used to receive digital signals containing application upgrade data input from the first server 14 and digital signals containing audio and video data input from the second server 15, respectively.

[0030] As one implementation, the multiplexer 12 further includes a digital signal output interface; through the digital signal output interface, the combined data of the application upgrade data and the audio and video data is transmitted to the transmitter 11 as a digital signal.

[0031] In this embodiment, the multiplexer 12 also includes a digital signal output interface (such as an ASI output interface) for transmitting the combined application upgrade data and audio / video data formed after multiplexing to the transmitter 11 in the form of a digital signal, so as to combine the application upgrade data with the regular audio / video data to realize the batch transmission of application upgrade data.

[0032] As a third optional embodiment of this example, the transmitter 11 includes: a signal exciter 111 and at least one power amplifier; the digital signal input interface of the signal exciter 111 receives the combined data in digital signal form transmitted by the multiplexer 12; the data signal output interface of the signal exciter 111 sequentially passes the combined data through each of the power amplifiers, and the last power amplifier transmits the received combined data to the broadcast signal transmission tower 2 through the feed tube 13.

[0033] In this embodiment, the transmitter 11 includes a signal exciter 111 and at least one power amplifier. The signal exciter 111 includes at least one digital signal input interface and at least one digital signal output interface. The signal exciter 111 receives the combined data in digital signal form transmitted by the multiplexer 12 through the digital signal input interface, performs encoding, correction, and other processing on the audio and video signals in the combined data, and also provides a highly stable carrier frequency signal for the transmitter 11. The processed combined data is then transmitted to the power amplifier through the digital signal output interface. The power amplifier can be divided into three parts: a driver preamplifier, a power amplifier stage, and a power combiner. The main task of the driver preamplifier is to amplify the carrier frequency signal output from the signal exciter 111 to a sufficient RF power signal to drive the power amplifier, thereby ensuring the safe and efficient operation of the RF power amplifier. The main task of the power amplifier stage is to generate the RF power signal required by the transmitter 11 by modulating the signal. The task of the power combiner is to combine the RF power signal generated by the power amplifier stage for transmission. The combined data passes through each power amplifier in sequence, and the last power amplifier (such as a power combiner) sends the combined data through feed tube 13 to the broadcast signal transmission tower 2 to ensure the stability and signal quality of the broadcast signal.

[0034] In one implementation of any of the above embodiments, the broadcast signal transmission tower 2 is a terrestrial wireless signal transmission tower; the merged data is transmitted by the broadcast signal transmission tower 2 to each application terminal 3 in the form of a terrestrial wireless signal.

[0035] In this embodiment, the broadcast signal transmission tower 2 is a terrestrial wireless signal transmission tower. The merged data is transmitted from the broadcast signal transmission tower 2 to each application terminal 3 using the terrestrial wireless signal as a carrier. This pushes application upgrade data to the application terminals 3 via terrestrial broadcast, enabling the application terminals 3 to upgrade their applications. The entire upgrade process requires no manual operation from the user, nor does it require the addition of any equipment or cables. Furthermore, application upgrade data can be sent in batches to achieve large-scale and rapid upgrades for different models of application terminals 3. For example, the terrestrial wireless signal transmission tower can be a television station transmission tower, and the terrestrial wireless signal is a terrestrial digital multimedia broadcast (DTMB) signal.

[0036] In one implementation of any of the above embodiments, the merged data includes an upgrade identifier for application upgrade data; the upgrade identifier is used to allow application terminal 3 to extract application upgrade data provided by different suppliers.

[0037] The upgrade identifier can be considered as the upgrade identifier inserted into the BAT and NIT tables in the PSI / SI information table. It can include the identifier of each application terminal manufacturer, the upgrade version number, and the packet identifier (PID) value used for application upgrade data.

[0038] In this embodiment, the merged data includes an upgrade identifier for application upgrade data, which is used to allow application terminal 3 to extract application upgrade data provided by different vendors.

[0039] In a specific example, application terminal 3, while running, queries the BAT, NIT, and PMT tables at regular intervals and parses each table to check for upgrade identifiers. If an upgrade identifier is detected in at least one table, the application terminal 3's manufacturer identifier and upgrade version number, among other parameters, are parsed from the upgrade identifier. Based on these parameters, it is determined whether application terminal 3 meets the upgrade requirements. Specifically, determining whether application terminal 3 meets the upgrade requirements based on the parsed parameters can involve checking if the parsed application terminal manufacturer identifier matches the manufacturer identifier recorded in application terminal 3 to prevent upgrade errors; if they match, it checks if the upgrade version number is higher than the current version number to prevent version rollback; if the upgrade version number is higher than the current version number, application terminal 3 proceeds with the upgrade according to the upgrade steps.

[0040] It should be noted that before sending the merged data to application terminal 3, the DVB-T descriptor in the SI table needs to be updated, and the conditional acceptance table (CAT) in the PSI / SI information table needs to be used to send an upgrade notification to application terminal 3. This ensures that application terminal 3 can read the upgrade notification through its built-in CA email information and display the upgrade notification to the user to avoid the user from performing a power outage operation during the upgrade process.

[0041] Before application terminal 3 begins the upgrade, the integrity and correctness of the received application upgrade data need to be checked. Specifically, this can involve first checking whether the application upgrade data has been received completely, then restoring the program code for CRC data verification, until the number of received data segments matches the total number of data segments in the descriptor, indicating that all application upgrade data has been received and the upgrade can proceed. Next, application terminal 3 can erase the old application data in its FALSH, and then write the new application upgrade data into its FALSH. After completion, application terminal 3 restarts, thus completing the application upgrade process. The above technical solution in this embodiment enables application terminal 3 to correctly identify the corresponding application upgrade data and achieve correct upgrades when performing batch upgrades on a large number of different models of application terminals 3, thereby solving the problem of application terminal 3 being unable to perform large-scale and rapid upgrades.

[0044] The multiplexer 12 includes two digital signal input interfaces: a first ASI input interface 121 and a second ASI input interface 122. It receives application upgrade data from the upgrade data management server via the first ASI input interface 121, and receives audio / video data and PSI / SI information tables from the transport stream content editing server via the second ASI input interface 122. The multiplexer 12 also includes a third ASI output interface 123 for transmitting the combined application upgrade data and the audio / video data as a digital signal to the transmitter 11.

[0045] The transmitter 11 includes a signal exciter 111, a first power amplifier 112, a second power amplifier 113, and a third power amplifier 114. The signal exciter 111 has a third ASI input interface 115 and a fourth ASI output interface 116. The third ASI input interface 115 is used to receive the combined data in digital signal form transmitted by the multiplexer 12. The fourth ASI output interface 116 is used to pass the combined data through each of the power amplifiers in sequence, and the third power amplifier 114 sends the received combined data to the broadcast signal transmission tower 2 through the feed tube 13.
