Description

technical field

[0001] The invention relates to a system in the technical field of video information processing, in particular to a real-time streaming media cluster transcoding system. Background technique

[0002] In the current audio and video codec field, there are international standards for different applications, such as MPEG-2 (Moving Picture Exports Group, Moving Picture Experts Group), MPEG-4, H.263 and AVC (Advanced Video Coding, advanced video coding ) and so on, these standards use different encoding methods and compression techniques to process the original video data, and transcode the original image sequence with a huge amount of data into compressed code streams in different formats. These standards are widely used in the fields of digital TV, Internet TV and mobile TV, but there are different technical standards on the information source, transmission system and receiving terminal for different applications. In systems that only support a certain standard o...
