[0002] Currently, emergency broadcasting systems from various manufacturers support the SIP protocol for voice broadcasting, but for music broadcasting, they do not follow a universal protocol. Each manufacturer uses its own proprietary protocol to implement music broadcasting, resulting in incompatibility between broadcast speakers from different manufacturers and the broadcasting system. This is particularly problematic in projects with broadcast speakers from different manufacturers, where older speakers have to be discarded, leading to significant resource waste. If the SIP protocol is used as the basic protocol for music broadcasting, broadcast speakers from different manufacturers can be used within the same system, solving the problem of cross-system incompatibility. Furthermore, using an extended SIP protocol allows for playback control, including setting playback counts, playback time, and loop tags.

[0003] Traditional music broadcasting methods lack a unified protocol, and the use of proprietary implementations by various manufacturers leads to incompatibility between devices and waste of resources. Traditional SIP music playback functions are limited and cannot support multiple files, multiple speakers, or flexible playback control, which are problems that urgently need to be solved.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0018] Traditional music broadcasting methods lack a unified protocol, and the use of proprietary implementations by various manufacturers leads to device incompatibility and waste of resources. Traditional SIP music playback functions are limited and cannot support multiple files, multiple speakers, or flexible playback control. Therefore, a multi-music file broadcasting control method based on the SIP protocol is needed. A general broadcasting control scheme based on the SIP protocol can achieve controllable playback of multiple audio files on multiple broadcasting speakers by carrying JSON format instructions through MESSAGE messages.

[0019] The preferred embodiment of the multi-music file broadcast control method based on the SIP protocol of the present invention, such as... Figure 1 and Figure 2 As shown, the multi-music file broadcast control method based on the SIP protocol includes the following steps: Step S10: Based on the operating terminal, obtain the playback options selected by the user, and convert the playback options to obtain structured data.

[0020] Step S10 includes: Step S11: Based on the operating terminal, obtain the list of music files selected by the user, the list of SIP accounts, and the playback control options; Step S12: Convert the list of music files to be played, the list of SIP accounts, and the playback control options according to the preset JSON format to obtain structured data.

[0021] Specifically, based on the operating terminal, the system obtains the user-selected list of music files, SIP account list, and playback control options. The system then converts the music file list, SIP account list, and playback control options according to a preset JSON format to obtain structured data.

[0022] In this embodiment, the user sends the selected music file playlist, playback control options, and SIP account list for the broadcast speaker to the SIP broadcast server via a MESSAGE message after organizing the above information in JSON format.

[0023] For example, such as Figure 2 As shown, the operating terminal is an interactive terminal for operating the broadcasting system and broadcast speakers. It can be a regular computer, operated using a web browser. Users can initiate playback control requests by selecting the list of uploaded music files and the list of broadcast speakers on the web interface; SIP broadcast server: used to manage broadcast speaker terminals, music files, and to conduct SIP calls and music file distribution; SIP broadcast speaker: a broadcast speaker device that supports the SIP protocol.

[0024] Step S20: Based on the SIP broadcast server, parse the structured data to obtain playback request information, and generate a response message according to the playback request information.

[0025] Step S20 includes: Step S21: Based on the SIP broadcast server, parse the structured data to obtain playback request information, and generate playback group sequence numbers according to the playback request information; Step S22: Associate the playback group number with the playback request information to obtain a response message.

[0026] Specifically, based on the SIP broadcast server, the structured data is parsed to obtain playback request information. A playback group sequence number is generated based on the playback request information (a MESSAGE message is sent to the SIP broadcast server, which parses the message and generates a playback group ID). The playback group sequence number is then associated with the playback request information to obtain a response message (a response message including the playback group ID is returned).

[0027] In this embodiment, after parsing the message, the SIP broadcast server generates a playback group ID (playback group sequence number), saves the playback group ID along with the playback track path and playback control options of the music file list, and then returns a response message including the playback group ID.

[0028] Step S21 includes: Step S211: Based on the SIP broadcast server, receive the SIP call instruction from the operating terminal, parse the structured data according to the SIP call instruction, and obtain playback request information; Step S212: Obtain the playback group sequence number. Decode the playback request information and the playback group sequence number according to the SIP call instruction to obtain the target playback group sequence number.

[0029] Specifically, based on the SIP broadcast server, the SIP call instruction from the operating terminal is received, the structured data is parsed according to the SIP call instruction to obtain playback request information, the playback group number is obtained, and the playback request information and the playback group number are decoded according to the SIP call instruction to obtain the target playback group number (after the SIP broadcast server receives this call, it parses out the list of broadcast speaker IDs associated with this group ID (target playback group number)).

[0030] In this embodiment, control signaling is transmitted based on the SIP protocol. SIP messages are transmitted via MESSAGE commands, specifically including instructions such as a list of music file paths, the SIP account of the designated speaker, the number of plays, whether to loop, and the playback duration. The SIP broadcast server implements a data parsing channel for MESSAGE communication, parsing the broadcast playback request sent by the operating terminal, specifically including the list of music file paths, the list of SIP accounts for the broadcast speakers, and playback control attribute information. This data is organized into JSON data and sent to the broadcast system via a MESSAGE message. After receiving this request, the broadcast system stores the above information in a cache database and associates it with a playback group ID. The operating terminal initiates a call to the playback group ID. After the SIP broadcast server finds the list of broadcast speaker accounts associated with this target playback group number, it calls each broadcast speaker terminal. Once the call is connected, it automatically distributes PCM audio data packets from the music file to the broadcast speakers in the group. Upon receiving the PCM audio data packets, the broadcast automatically begins playback.

[0031] Step S30: Based on the SIP broadcast server, parse the response message to obtain a list of broadcast speaker accounts, and control multiple broadcast speakers to play sequentially according to the list of broadcast speaker accounts.

[0032] Step S30 includes: Step S31: Based on the SIP broadcast server, parse the response message according to the SIP call command and the playback group number to obtain the broadcast speaker account list; Step S32: Decode the response message according to the broadcast speaker account list and the SIP call command to obtain PCM audio data packets; Step S33: Control multiple broadcast speakers to play the audio in sequence according to the PCM audio data packet.

[0033] Specifically, step S30 further includes obtaining the control playback duration, playback count, loop playback tag, and BYE message; determining whether the playback control option, playback count, and loop playback tag have reached preset conditions; if the playback control option, playback count, and loop playback tag have reached preset conditions, then controlling multiple broadcast speakers to stop music playback according to the BYE message (music file playback and control: the SIP broadcast server controls the playback duration, playback count, and loop playback tag according to the playback control option; after the above playback control conditions are met, the SIP broadcast server sends a BYE message to each broadcast speaker ID to hang up the call and end music playback); based on the SIP broadcast server, parsing the response message according to the SIP call command and the playback group sequence number to obtain a broadcast speaker account list; decoding the response message according to the broadcast speaker account list and the SIP call command to obtain PCM audio data packets; and controlling multiple broadcast speakers to play sequentially according to the PCM audio data packets.

[0034] Step S32 includes: Step S321: Decode the response message according to the list of broadcast speaker accounts and the SIP call command to obtain multiple music files; Step S322: Encapsulate all the music files into a format to obtain a PCM audio data packet.

[0035] Specifically, the response message is decoded according to the list of broadcast speaker accounts and the SIP call command to obtain multiple music files. All the music files are then formatted and encapsulated to obtain PCM audio data packets. (After the call is connected, the music files in the playback track path list of the broadcast speaker account list are decoded into PCM audio data packets one by one and sent to the broadcast speaker using the RTP packet protocol. The broadcast speaker decodes the received audio data packets and plays them.)

[0036] In this embodiment, a SIP number is first assigned to the SIP broadcast speaker and configured. After the broadcast speaker registers with the broadcast system, it can broadcast music. Using the method described in Embodiment 1, control commands for music file playback are issued to the broadcast speaker via the SIP channel, demonstrating feasibility and versatility. User: As the operator of the SIP broadcast system, the user can control playback through a web interface, including pause, stop, next track, and previous track operations. SIP Broadcast Server: The SIP server serves as the interaction platform between the user and the broadcast speaker terminal, controlling music playback and other functions through the system's HTTP API and SIP channel. Broadcast Speaker Terminal: A broadcast speaker device supporting the SIP protocol; SIP Broadcast Speaker: Upon receiving a call from the SIP broadcast server, it automatically answers and plays the audio packets forwarded by the broadcast server.

[0037] Furthermore, such as Figure 3 As shown, based on the above-described multi-music file broadcast control method based on the SIP protocol, the present invention also provides a system for controlling multi-music file broadcasts based on the SIP protocol, wherein the system for controlling multi-music file broadcasts based on the SIP protocol includes: Data conversion module 51 is used to obtain the playback options selected by the user based on the operating terminal, and convert the playback options to obtain structured data; Data parsing module 52 is used to parse the structured data based on the SIP broadcast server to obtain playback request information and generate a response message based on the playback request information; The speaker playback module 53 is used to parse the response message based on the SIP broadcast server to obtain a list of broadcast speaker accounts, and control multiple broadcast speakers to play sequentially according to the list of broadcast speaker accounts.

[0038] Furthermore, such as Figure 4 As shown, based on the above-mentioned multi-music file broadcast control method and system based on the SIP protocol, the present invention also provides a terminal, which includes a processor 10, a memory 20 and a display 30.

Furthermore, the memory 20 may include both internal and external storage devices. The memory 20 is used to store application software and various types of data installed on the terminal, such as the program code installed on the terminal. The memory 20 can also be used to temporarily store data that has been output or will be output. In one embodiment, the memory 20 stores a multi-music file broadcast control program 40 based on the SIP protocol. This SIP-based multi-music file broadcast control program 40 can be executed by the processor 10 to implement the SIP-based multi-music file broadcast control method of this application.

[0041] In some embodiments, the display 30 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, or an OLED (Organic Light-Emitting Diode) touchscreen. The display 30 is used to display information on the terminal and to display a visual user interface. The terminals communicate with each other via a system bus.
