Abstract
In a block-based video stream, a first bit representing video data at a predefined location is identified. The video data at the first bit is replaced with a bit of non-video data prior to being transmitted to a device used to process the block-based video stream. Additional bits of non-video information are transmitted by replacing additional bits of video data within the block based video stream. A processing device that receives the block-based video stream accesses the non-video bits to obtain the non-video data.
