Description

technical field

[0001] The present invention relates to video information transcoding technology, in particular, relates to a method that can be adapted to adapt source video in a heterogeneous network environment according to different network bandwidths, channel bit error rates, and video information processing and display capabilities of end devices. It is an adaptive video transcoding gateway with multiple conversion functions that can be converted into video streams suitable for transmission and display to adapt to narrower transmission channels and the access of end devices with weaker processing and display capabilities. Background technique

[0002] Due to the differences in various multimedia video and audio encoding formats and the multimedia communication network is composed of different network structures and protocols, a multimedia communication method that can span heterogeneous networks is required in many cases.

[0003] For example, in a video on demand (VOD...
