Method and apparatus for forwarding television channel video image snapshots to an auxiliary display device
Abstract:
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.
