Abstract
In an example, a device may include logic to receive a plurality of video frames from a video source, logic to process the plurality of video frames, logic to provide at least some of the plurality of video frames to a video sink, and logic to reduce a display latency of each of the video frames provided to the video sink by changing the frame rate of some or all of the frames.
Claims20
A device, comprising:
- logic to receive a plurality of video frames from a video source at a fixed frame rate, the plurality of received video frames comprising a video frame that comprises a first plurality of sub-frames;
- logic to process at least some of the plurality of video frames to produce a plurality of processed video frames, wherein:
- processing at least some of the plurality of video frames comprises processing at least some of the first plurality of sub-frames;
- and
- processing at least some of the plurality of the video frames decouples the fixed frame rate of the received video frames from a flexible frame rate of the processed video frames;
- and
- logic to provide at least some of the plurality of processed video frames, including at least some of the processed first plurality of sub-frames, to a video sink at the flexible frame rate.

A set-top box, comprising:
- an input interface configured to receive a plurality of video frames from a video source at a fixed frame rate, the plurality of received video frames comprising a video frame that comprises a first plurality of sub-frames;
- a processor configured to process at least some of the plurality of video frames to produce a plurality of processed video frames, wherein:
- processing at least some of the plurality of video frames comprises processing at least some of the first plurality of sub-frames;
- and
- processing at least some of the plurality of the video frames decouples the fixed frame rate of the received video frames from a flexible frame rate of the processed video frames;
- an output interface configured to provide at least some of the processed video frames, including at least some of the plurality of processed sub-frames, to a video sink at the flexible frame rate.
