Problems solved by technology
When a software and hardware fault occurs in an encoder or a link to the network fails, the user's on-demand live service will be interrupted. In order to ensure the user experience, it is necessary to design a fast fault protection mechanism to allow the user to get the live video image again. Not just to notify the user to quickly fix the fault

The invention relates to an audio and video encoder. Audio and video streams are transmitted under different conditions through two independent audio and video stream transmission links. W, wherein one transmission link is a normally working transmission link composed of an audio and video input interface, a resource temporary storage module, an audio and video compression coding module, an audioand video main output interface and a transit server; the resource scheduling module is used for judging through which data link the audio and video streams acquired by the audio and video acquisitionterminal are transmitted; when an audio and video compression coding module in the machine breaks down, the processor is started; an audio and video input interface, a resource temporary storage module, an audio and video standby output interface, a transit server and other audio and video encoder links are used to transmit; audio and video streams acquired locally are transmitted to other audioand video encoders in idle states in a video monitoring network to perform compressed encoding on the audio and video streams, and then the audio and video streams are output to a transit server to bepushed by the transit server in a unified manner, so that and therefore the reliability of the encoders is ensured.
Description
technical field [0001] The invention relates to the technical field of audio and video encoders, in particular to an audio and video encoder. Background technique [0002] The video encoder is composed of a dedicated audio and video compression codec chip, data and alarm input and output channels, network interface, audio and video interface (HDMI, VGA, HD-SDI), RS232 serial interface control, protocol interface control, embedded software, etc. . [0003] With the wide application of video surveillance technology in traffic and public security systems, the reliability requirements for the entire video surveillance system are getting higher and higher. Among them, the reliability of the video surveillance server can already be achieved through dual-machine backup technology, but how to improve The reliability of the front-end encoder is one of the urgent problems we face. When a software and hardware fault occurs in an encoder or a link to the network fails, the user's on-d...
