Abstract: In one embodiment, a receiver for an accelerated channel change is provided. The receiver receives a first version of a video stream for a first channel and causes display of video for the first version of the video stream for the channel. A second version of a video stream is received upon a channel change to a second channel, the second version including non-discardable pictures from the first version of the video stream. The receiver displays video for the second version of the video stream for the second channel. When a transition point is reached in the first version of the video stream for the second channel, a first version of a video stream for the second channel can be displayed.
