Patent ID: 8184142

Claim:
An apparatus for creating a composed video image from video image data representing two or more video images, comprising: a compressed video data interface; and a processor that: retrieves compressed video image data for the two or more video images from the compressed video data interface, wherein the compressed video image data for each image comprises organized network abstraction layer (ONAL) units, each ONAL unit originating from only one network abstraction layer (NAL) unit and originating from only one row of macroblocks (MBs) within a frame of the compressed video image data of its video image; converts the ONAL units of each of the video images onto ONAL units to be stored in a frame memory of composed video image data, wherein each one of the ONAL units of the composed video image data is originated from one ONAL unit within the retrieved compressed video image data; and transmits the composed frame memory of the composed video image data to the compressed video data interface.
