Abstract
Abstract The present invention provides methods, systems and apparatus to manage processing of video content. In one implementation, a method of managing processing of video content is provided. The video content includes picture data representing picture elements to be rendered for display to a user. The embedded data is conveyed along with the video content. The method includes: (a) examining the embedded data for rights data, wherein the rights data is carried by a header; (b) only if the rights data is missing, examining the embedding data for protect data that is contained within the picture data; and (c) if the rights data is missing and the protect data is present, then limiting processing of the video content. Other implementations are provided as well.

Dependent Claim
36 words
The method of claim 3 wherein the copy control data represents one of a plurality of states, the states comprising al least: i) copy once; ii) copy freely; iii) copy no more; and iv) copy never.
Claim 7
Independent Claim
98 words
A method of managing processing of video content, the video content including picture data representing picture elements to be rendered for display to a user, where embedded data is conveyed along with the video content, the method including: (a) examining the embedded data for rights data, wherein the rights data is carried by a header; (b) only if the rights data is missing, examining the embedded data for protect data that is contained within the picture data; and (c) if the rights data is missing and the protect data is present, then limiting processing of the video content.
Claim 8
Independent Claim
98 words
