Method and apparatus for forwarding television channel video image snapshots to an auxiliary display device
View Patent ↗A method of processing television content metadata in a communications system. The system includes a consumer device (e.g., a set-top box and/or television) in communication with an auxiliary display device (e.g., webpad). A broadcast television channel video image signal and the metadata are received by the consumer device. A single video image frame of the broadcast television channel video image signal is captured when a predefined indicator is detected in the metadata. The metadata is modified by changing the predefined indicator to an image identifier associated with the single video image frame. The single video image frame is converted to a well-known format, and the consumer device sends the modified metadata and the converted single video image frame to the auxiliary display device for display thereon.
1. A method of processing television content metadata in a communications system, the system including a consumer device in communication with an auxiliary display device, the method comprising:
(a) the auxiliary display device receiving metadata associated with a broadcast television channel video image signal from the consumer device;
(b) in response to detecting a predefined indicator in the metadata, the auxiliary display device automatically sending an image frame request signal to the consumer device;
(c) in response to the image frame request signal, the consumer device capturing a single video image frame of the broadcast television channel video signal; and
(d) the consumer device sending the single video image frame to the auxiliary display device for display thereon.
2. The method of claim 1 wherein the consumer device is a set-top box (STB).
3. The method of claim 1 wherein the consumer device is a television.
4. The method of claim 1 wherein the predefined indicator is a “tv:” uniform resource locator (URL).
5. The method of claim 1 wherein the metadata includes advanced television enhancement forum (ATVEF) data.
6. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises the consumer device converting the MPEG image frame to a Joint Photographic Experts Group (JPEG) image frame.
7. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises converting the MPEG image frame to a Tagged Image File Format (TIFF) image frame.
8. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises converting the MPEG image frame to a Graphic Interchange File Format (GIFF) image frame.
9. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises converting the MPEG image frame to a Portable Network Graphics (PNG) image frame.
10. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises converting the MPEG image frame to an Encapsulated PostScript File (EPSF) image frame.
11. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises converting the MPEG image frame to a bitmap graphics file image frame.
12. The method of claim 1 wherein the single video image frame is a Moving Picture Experts Group (MPEG) image frame, and step (c) further comprises converting the MPEG image frame to an object oriented graphics file image frame.
