Carriage systems encoding or decoding JPEG 2000 video
First Claim
1. A method of decoding JPEG 2000 (J2K) video elementary streams carried in transport streams, the method comprising:
- receiving a transport stream including a J2K video elementary stream including J2K video access units, each J2K video access unit includingan elementary stream (ELSM) header including video-related parameters associated with decoding and displaying image data associated with the J2K video access unit,a packetetized elementary stream (PES) header including timing reference information including a presentation time stamp (PTS), andone or more codestreams associated with each J2K video access unit;
retrieving each J2K video access unit, present in the J2K video elementary stream in a monotonic order; and
decoding the retrieved video access unit using the video-related parameters to form a signal including decoded J2K image data.

Abstract
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.

12. A decoding system configured to decode JPEG 2000 (J2K) video elementary streams carried in transport streams, the system comprising:
-
a processor configured to; receive a transport stream carrying a J2K video elementary stream including J2K video access units, wherein each J2K video access unit includes; an elementary stream (ELSM) header with video-related parameters for decoding the access unit, and a packetized elementary stream (PES) header including timing reference information including a presentation time stamp (PTS); wherein the J2K video access units are ordered in the J2K video elementary stream in a monotonic display order; decode the J2K video access units using the video-related parameters included in each J2K video access unit to form a signal including decoded J2K image data; and a storage buffer in communication with said processor, said storage buffer configured to buffer the J2K video access units and video-related parameters. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
