CARRIAGE SYSTEMS ENCODING OR DECODING JPEG 2000 VIDEO
A system configured to decode video data in a packetized elementary stream (PES) including frames of image data. The system includes a processor configured to receive a transport stream including control information associated with the image data including video metadata parameters associated with application specific functions applicable to the image data. The processor is also configured to receive the PES including the frames of image data in video access units. The processor is configured to retrieve and decode the retrieved video access units using the control information to form a signal including the frames of image data. The system also includes a storage device configured to store the frames of image data and the control information.
