Abstract
A system and method that provides a connection path between a video source such as a personal computer (PC) and a high-definition television (HDTV). A control is provided for varying a quality level of a video signal with respect to latency of activities provided through the video signal channel. Output picture quality versus latency is adjusted on a dynamic basis. Observed mouse activities causes the output picture quality to be decreased rapidly with an attendant decrease in latency. A decrease in output picture quality and latency is maintained until the occurrence of a particular event, such as the expiration of a time interval from a last observed mouse event. If a limited number of mouse events are observed, then the output picture quality is increased to a point at which the limited mouse activity can be accommodated with an acceptable level of latency. If limited or no mouse events are observed for a given period of time, the output picture quality is increased, either rapidly or gradually, until output picture quality is restored or another mouse event is observed.
