Abstract
A method for redirecting video content includes receiving a video signal at the set-top box and decoding the video signal to produce unrendered video data. The unrendered video data is encoded and provided to the remote device via a wide area network. By encoding unrendered, rather than rendered, video data for transmission to the remote device, the need for an encoding device external to the set-top box is obviated.
Claims20
A method, comprising:
- receiving at a gateway device a video packet stream from a remote television server via an internet protocol television network;
- transmitting the received video packet stream to a set-top box;
- receiving at the gateway device a request for selected video content;
- transmitting the received request for the selected video content to the set-top box;
- receiving at the gateway device encoded video data from the set-top box and corresponding to the selected video content, wherein the video packet stream is configured for decoding by the set-top box to produce unrendered video data, and wherein the unrendered video data is configured for encoding by the set top box to produce the encoded video data;
- and
- transmitting the received encoded video data to a display device over a wide area network.

A method, comprising:
- transmitting from a gateway device to a set-top box a video packet stream from an internet protocol television network;
- transmitting from the gateway device to the set-top box a request for selected video content originating from a display device coupled to the gateway device by way of a wide area network;
- and
- transmitting from the gateway device to the display device encoded video data corresponding to the selected video content, wherein the encoded video data originates at the set-top box and wherein the set-top box is operable to:
- decode the video packet stream to produce unrendered video data;
- and
- encode the unrendered video data to produce the encoded video data.
