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.

Claims

1. A method of decoding video data in a packetized elementary stream (PES) including frames of image data, the method comprising:

receiving 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 and

the PES, wherein the PES includes the frames of image data in video access units, each video access unit including

an elementary stream (ELSM) header including image data metadata parameters associated with decoding and displaying the image data,

a PES header including timing reference information including a presentation time stamp (PTS), and

one or more codestreams associated with a frame of the image data;

retrieving each video access unit present in a monotonic order associated with the PTS in the PES header of the video access unit; and

decoding the retrieved video access unit using the control information to form a signal including the frames of image data,

wherein the video metadata parameters include a parameter identifying a time code associated with each video access unit, and

wherein the video metadata parameters include a parameter identifying a frame count associated with each video access unit.
