METHOD FOR REDUCING CHANNEL CHANGE TIMES IN A DIGITAL VIDEO APPARATUS

摘要

A digital video apparatus provides reduced channel change times. According to an exemplary embodiment, the digital video apparatus includes at least one receiver for receiving first and second video streams representing the same program, wherein the first video stream has at least one characteristic different from the second video stream; a first signal processor for processing the first video stream to generate a first processed video stream; a second signal processor for processing the second video stream to generate a second processed video stream having a delay with respect to the first processed video stream; a renderer for rendering the second processed video stream responsive to a channel change command; and a switch for switching from the second processed video stream to the first processed video stream after the renderer begins rendering the second processed video stream, and thereby causing the renderer to begin rendering the first processed video stream.
