Abstract

Present invention relates to implementing method and system for broadcasting real-time audio/video stream. The system comprises a platform server, multiple streaming servers, and at least one live broadcast server, wherein, each live broadcast server connects to a multimedia platform. First, the platform server can establish a real-time audio/video for a real-time audio/video signal, and after that the platform server can assign one of streaming servers to a live broadcast source, and after that the platform server can source a stream key and a stream url from a designated live broadcast server according to a up streaming command, and after that the real-time audio/video signal can be transferred from the streaming server to the designated live broadcast server. In this way, the media workers will not need to login or access to each mulitmedia platform(e.g. Youtube, Facebook...) manually so as to obtain the stream key and a stream url, and present invention can reduce the personnel operates inconveniently.

Description

Instant video and audio relay system and its implementation method

The invention relates to a real-time video and audio rebroadcasting system, in particular to a real-time video and audio signal that can be received from a video and audio signal source, and after a stream server is designated as the live video signal source address of the real-time video signal, it is forwarded according to a live video signal Instruction to transmit the real-time video signal to the "live video and audio relay system and its implementation method" of the designated live server by push streaming.

Rebroadcasting work is very demanding and mobile for media workers. Generally speaking, the traditional broadcast work is to send a signal to a satellite through a news interview vehicle (SNV), and the TV station receives the signal from the satellite and broadcasts it. The SNG live broadcast (SATELLITE NEWS GATHERING) was achieved. However, the cost of the news interview vehicle is quite high, and there are geographical restrictions on the interview vehicle that may not reach the news site. Therefore, some inventors suggested that media reporters can use a mobile live broadcast device (such as mobile phones, Or a camera that can be plugged into a 4G network card) to send a real-time audio and video signal from the news site to the news center via a mobile network or the Internet. After the news center completes the process of editing, subscripting, and subtitling, it can be generated. An instant news screen of real-time audio and video signals.

However, when the news center needs to forward the real-time news screen, media workers must first log in and connect to different multimedia platforms (such as streaming audio and video platforms or community platforms) and create the real-time news screen. A live video, to obtain a streaming key (Stream Key) and a server address (Server URL) belonging to each live video from each multimedia platform, and then, the news center can only send the live video The key and the server address separately send connection requests (such as POST requests) to each multimedia platform, so that the live news screen can be broadcast live on the multimedia platform, but as a result, once there are many live videos in the news center that need to be broadcast, and /Or when each live video needs to be broadcast live on multiple multimedia platforms, the media workers will spend a considerable amount of time for the news center to establish a connection with the multimedia platform. In short, the previous media workers targeted each live video, All need to spend a lot of time on the above-mentioned preparatory work.

Therefore, how to effectively forward the real-time audio and video signals to the multimedia platforms operated by different service providers for the current live broadcast of media workers, so as to fully meet the real-time and convenience of broadcast and reduce the news center The cost and time of rebroadcasting are problems to be solved.

In view of the above problems, the present inventors have conducted research on streaming live broadcasting and news live broadcasting technologies based on years of experience in research in related fields; therefore, the purpose of the present invention is to provide an efficient video and audio signal Forwarded to a multimedia platform operated by different service providers to fully satisfy the real-time and convenience of the broadcast, thereby reducing the broadcast cost and time of the media workers. "Real-time video and audio broadcast system and its implementation method."

To achieve the above purpose, the instant video and audio relay system disclosed in the present invention is used to receive at least one real-time audio and video signal from a source of audio and video signals (such as 4G packets) and push it to at least one live server. A platform server, a plurality of streaming servers, and at least one live broadcast server, wherein the platform server has a live broadcast source creation module and a live broadcast source forwarding module, and each streaming server and the platform server present Information link, and corresponding to a live signal source address; the key of the present invention is that after the live source creation module is triggered, a live video can be created for real-time audio and video signals, and one of the live signal source addresses is designated as The audio and video signal source transmits the destination address of the real-time audio and video signal, and then, the live source forwarding module can receive a live signal forwarding instruction, and according to the live signal server corresponding to the live signal forwarding instruction, the platform server and the live server Perform concatenation, and after obtaining at least a sending key and a live server address, enable live streaming video to be streamed from the designated streaming server to the designated live server; thereby, it can be efficiently Forward real-time audio and video signals to multimedia platforms (streaming audio and video/community platforms) operated by different service providers to fully meet the real-time and convenience of broadcasting, thereby reducing the cost and time of broadcasting for media workers.
