Method for encoding video with non-compressed mode and device implementing the method

摘要

The method involves compressing a macro block being processed by a coding loop in a normal coding mode, where the compression is considered efficient if the size occupied by the block is noticeably less than the size occupied by the block without compression. A non-compressed mode is activated when the compression is not efficient, where samples of a source video corresponding to the block being processed are transmitted without compression. The non-compressed mode is maintained after activation of the mode when functional elements of the loop have not returned to a stable state. An independent claim is also included for a video coding device comprising a coding loop.
