Methods, apparatus, and systems for managing the insertion of overlay content into a video signal
First Claim
1. A method for inserting overlay content into a video signal to provide a modified packetized bit stream containing both video and overlay content for subsequent transmission to a receiver, comprising:
- receiving a compressed bit stream carrying a video signal from a video source;
providing overlay content in one or more overlay content signals; and
inserting overlay content selected from one of said one or more overlay content signals into an insertion window of said video signal, without decoding the compressed bit stream, to produce said modified packetized bit stream, said overlay content being carried in a payload portion of said modified packetized bit stream together with video content from said video signal;
wherein the modified packetized bit stream is a single program bit stream containing both the video and overlay content for transmission to and decoding at the receiver.

Abstract
Methods, apparatus, and systems for managing the insertion of overlay content into a video signal are provided. A video signal is received from a video source. In addition, overlay content is provided in one or more overlay content signals. A tag is appended to the video signal and/or the overlay content signals. The tag contains identifying information. Overlay content selected from one of the overlay content signals may then be inserted into the video signal in accordance with the identifying information to produce a modified video content. The identifying information may comprises various types of information identifying the source or subject matter of the overlay content or video signal, the destination of the overlay content or video signal, information identifying the geographic region where the overlay content is to be inserted, or key words or other information to enable matching of the overlay content with an appropriate video signal.

18. A system for inserting overlay content into a video signal to provide a modified packetized bit stream containing both video and overlay content for subsequent transmission to a receiver, comprising:
-
a network switch for receiving a compressed bit stream carrying a video signal from a video source; an overlay generator for providing overlay content in one or more overlay content signals to said network switch; a video processor in communication with said network switch, said video processor being adapted for; selecting overlay content from one of said one or more overlay content signals; and inserting the selected overlay content into an insertion window of said video signal, without decoding the compressed bit stream to produce said modified packetized bit stream, said overlay content being carried in a payload portion of said modified packetized bit stream together with video content from said video signal; wherein the modified packetized bit stream is a single program bit stream containing both the video and overlay content for transmission to and decoding at the receiver. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
