摘要： Methods and systems for achieving a high frame rate video with compatibility for existing receivers without depending bitstream encoding are provided herein. For example, an apparatus comprises: a memory; and one or more processors configured to execute instructions stored in the memory. The instructions comprise: receiving a first bitstream having a first packet identifier (“PID”) and a second bitstream having a second PID; decoding the first bitstream and the second bitstream; and interleaving the decoded first bitstream and the decoded second bitstream to form a high frame rate video signal, wherein the high frame rate video signal has a frame rate equal to the sum of the frame rate of the decoded first bitstream and the decoded second bitstream.

摘要： 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.
