Abstract
Graphics metadata is embedded in an input video signal at a first system, to form a processed video signal which is distributed to a plurality of second systems, typically cable or broadcast systems. Each individual second system can edit the metadata and insert graphics into the video based on the edited metadata so as to form a final signal for broadcast or other distribution to viewers. Thus, each second system can provide a final signal with an appearance consistent with the brand identity of that individual second system. The metadata facilitates storage and retrieval of the video.

26. A video processing system having:
-
(a) an input for receiving an input video signal;
(b) a character generator subsystem connected to said input, said character generator subsystem being operative to provide graphics metadata defining one or more graphics and add said graphics metadata to the input video signal so as to provide a processed video signal; and
(c) a processed signal output connected to said character generator subsystem. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
