Problems solved by technology
[0007] The purpose of the present invention is to provide a system and method for video encoding, which can simultaneously encode multiple video output formats for the same video source, which not only solves the timeliness requirements of users for encoding, but also can use only one device. It can meet the requirements of outputting a variety of bit rates, and also solves the cost problem of encoding equipment. At the same time, because it is encoded by one device and outputs multiple channels at the same time, it can realize smooth bit rate switching of Internet live broadcasting

The invention discloses a video encoding system and a video encoding method. The video encoding method includes: an audio and video acquisition device acquires audio streams and video streams of an audio and video signal source and transmits the audio streams and video streams to a decoder; the decoder invokes a corresponding decoding module for decoding and processing according to formats of the audio streams and video streams to acquire original audio stream and video stream data, replicates the data in a preset quantity and transmits the data to a multichannel encoding device; the multichannel encoding device encodes according to preset encoding formats and encoding rate to generate corresponding audio and video synchronous information and transmits the synchronous information to a multichannel encoding packaging device; and the multichannel encoding packaging device packages the encoded audio streams and video streams into audio and video streams of preset packaging formats and transmits the audio and video streams to a video file storage device which stores the audio and video streams to audio and video files. By the video encoding system and the video encoding method, multichannel video output format encoding for the same video source can be effectively achieved, the requirements of users on encoding timeliness and the requirements on encoding equipment cost are met, and smooth rate switching of live broadcasting via internet can be achieved.
Description
technical field [0001] The present invention relates to the technical field of video coding, in particular to a video coding system and method. Background technique [0002] Historically, video signals were stored on magnetic tape in analog form. With the continuous development of technology, audio signals are stored digitally, and video signals have also begun to use digital formats, and some related technologies have also begun to develop accordingly. A coding method is needed to compress and transmit audio and video. The so-called video encoding method refers to the method of converting a video format file into another video format file through a specific compression technology. At present, the most important coding and decoding standards in video stream transmission include ITU's H.264, M-JPEG of the Motion Still Picture Experts Group, and MPEG series standards of the International Standardization Organization's Motion Picture Experts Group. In addition, it is widely us...
