Abstract

According to example configurations herein, a downstream video processor operates in conjunction with an existing consumer-operated tuner system. The downstream video processor system can be an add-on system disposed in a communication link between the consumer-operated tuner system and a remote video playback device such as a hi-definition television. In lieu of processing video data locally in the set-top box, the consumer-operated tuner system can transmit the video data to the downstream video processor for processing. The downstream video processor in the communication link can be configured to provide enhanced video processing services (e.g., better resolution, higher frame rate rates, enhanced signal to noise ratio, enhanced color quality, 3-D graphics, etc.) with respect to video processing services supported by an upstream video decoder in the consumer-operated tuner system.
