And enabling the modification of the metadata and the motion prediction and delta compression for rendering images to a remote display

摘要

Delta compression may be achieved by processing video data for wireless transmission in a manner which reduces or avoids motion estimation by a compression process. Video data and corresponding metadata may be captured at a composition engine. Frame buffer updates may be created from the data and metadata. The frame buffer updates may include data relating to video macroblocks including pixel data and header information. The frame buffer updates may include pixel reference data, motion vectors, macroblock type, and other data to recreate a video image. The macroblock data and header information may be translated into a format recognizable to a compression algorithm (such as MPEG-2) then encoded and wirelessly transmitted.
