SYSTEM AND METHOD FOR SIGNALING CHARACTERISTICS OF PICTURES' INTERDEPENDENCIES
First Claim
1. A method for signaling characteristics of pictures'"'"' interdependencies in a video signal in subscriber television systems, said method comprising the steps of:
- providing a transport layer of a video program;
allocating auxiliary information at the transport layer to determine whether a picture is one of the following;
a discardable picture, a forward predicted picture, a backward predicted picture, and a bidirectional predicted picture, the auxiliary information at the transport layer being unencrypted and transmitted as part of private data or an adaptation field; and
determining whether to drop the picture corresponding to the auxiliary information without having to parse a video stream.

Abstract
Disclosed are systems and methods for signaling characteristics of picture interdependencies in a video signal in subscriber television systems. In this regard, a representative method comprises allocating auxiliary information at a transport layer of a video program as to determine whether a picture is one of the following: discardable picture, forward predicted picture, a backward predicted picture, and a bi-directional predicted picture. The auxiliary information at the transport layer is generally unencrypted and transmitted as part of private data or an adaptation field. The auxiliary information enables a video decoder to determine whether to drop the picture corresponding to the auxiliary information without having to parse a video stream.

8. A set top box for processing characteristics of pictures'"'"' interdependencies in a video signal in subscriber television systems, the set top box comprising:
-
a channel decoder that receives a channel from a network and generates a transport stream; a transport decoder that receives the transport stream and decodes auxiliary information at a transport layer of a video program to determine whether a picture is one of the following;
a discardable picture, a forward predicted picture, a backward predicted picture, and a bi-directional predicted picture, the auxiliary information at the transport layer being unencrypted and transmitted as part of private data or an adaptation field; anda video decoder that determines whether to drop the picture corresponding to the auxiliary information without having to parse a video stream. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable medium having a computer program for signaling characteristics of pictures'"'"' interdependencies in a video signal in subscriber television systems, said computer-readable medium comprising:
-
logic configured to provide a transport layer of a video program; logic configured to allocate auxiliary information at the transport layer to determine whether a picture is one of the following;
a discardable picture, a forward predicted picture, a backward predicted picture, and a bidrectional predicted picture, the auxiliary information at the transport layer being unencrypted and transmitted as part of private data or an adaptation field; andlogic configured to determine whether to drop the picture corresponding to the auxiliary information without having to parse a video stream. - View Dependent Claims (16, 17, 18, 19, 20)
