SIDE INFORMATION FOR VIDEO DATA TRANSMISSION

Systems, apparatuses, and methods for performing efficient video compression are disclosed. A video processing system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter includes a processor and an encoder. The processor generates rendered blocks of pixels of a video frame, and when the processor predicts a compression level for a given region of the video frame is different from a compression level for immediately neighboring blocks, the processor generates side information. The side information identifies a location of the given region in the video frame and a type of content that causes the compression level differences. The processor sends the rendered video information and the side information as accompanying metadata to the encoder. The encoder updates encoding parameters based on the received side information, and compresses the rendered given region based on the updated encoding parameters.
