Audio and video encoder based on wide area network live broadcast and working method thereof

Abstract

The invention provides an audio and video encoder based on wide area network live broadcast and a working method thereof. The audio and video encoder comprises a signal input module, an encoding module, a network protocol encapsulation module and a data pushing module, wherein the signal input module comprises more than two audio and video input interfaces and an audio and video A / D (Analog to Digital) conversion module for digitalizing input audio and video data and transmitting the digitalized input audio-video data to the encoding module; the encoding module is used for compressing and encoding the received audio and video digital data and transmitting the compressed and encoded audio and video digital data to the network protocol encapsulation module; the network protocol encapsulation module comprises a protocol encapsulation module which is used for performing protocol encapsulation on the compressed and encoded audio and video data; the data pushing module is used for pushing the protocol-encapsulated audio and video data to a streaming media server. A plurality of network protocols can be embedded, and the audio and video data can be pushed to the streaming media server in a wide area network. Meanwhile, various audio and video input interfaces are available, so that various practical application requirements are met.

Description

technical field [0001] The invention relates to an audio and video encoder based on wide area network live broadcast and its working method, in particular to an audio and video encoder suitable for broadcasting and television field and its working method. Background technique [0002] In the real-time live broadcast streaming media service system, the encoder is used to compress and encode the audio and video data collected on the spot, and then push it to the streaming media server, and the streaming media server distributes the audio and video data to achieve live broadcast. [0003] The output protocol supported by the traditional encoder is single, and the data cannot be pushed in the wide area network. Therefore, the encoder and the streaming media server must be in the same local area network, which brings restrictions to the deployment of the streaming media service system. [0004] In practical applications, the encoder still has the problem of a single input interfa...

Problems solved by technology

[0003] The output protocol supported by the traditional encoder is single, and the data cannot be pushed in the wide area network. Therefore, the encoder and the streaming media server must be in the same local area network, which brings restrictions to the deployment of the streaming media service system.

[0004] In practical applications, the encoder still has the problem of a single input interface, so there are specific requirements for the output interface of the audio and video acquisition equipment
