Anticipatory video signal reception and processing
A system and method that provide reduced latency in a video signal processing system. Various aspects of the present invention may comprise receiving a current request from a user for first video information. Such a request may, for example, be received with a user interface module. A first video stream and a second video stream may be received simultaneously, where the first video stream comprises the first video information currently requested by the user, and the second video stream comprises second video information not currently requested by the user. A video receiver module may, for example, perform such receiving. The first video stream may be processed to present the first video information to the user at the current time. Further, the second video stream may be pre-processed in preparation for being presented to the user in the future. A video processing module may, for example, perform such video stream processing.
