Abstract
At one of a video source device and a video sink device, an indication of video processing capabilities of the other of the video source device and said video sink device is received. Based upon the indication and an indication of video processing capabilities of the one device, one of a plurality of video processing algorithms is selected for execution by the one device. The selecting may be based upon a set of precedence rules. Categories of video processing may for example include scan-rate conversion, interlacing, de-interlacing, de-noise, scaling, color correction, contrast correction and detail enhancement.
Claims22
A method comprising, at one of a video source device and a video sink device:
- receiving an indication of video processing capabilities of the other of said video source device and said video sink device;
- and
- based upon:
- (a) said indication;
- and
- (b) an indication of video processing capabilities of said one device,
- selecting one of a plurality of video processing algorithms for execution by said one device.
A machine-readable medium storing instructions that, when executed by a processor of one of a video source device and a video sink device, cause said one device to:
- receive an indication of video processing capabilities of the other of said video source device and said video sink device;
- and
- based upon:
- (a) said indication;
- and
- (b) an indication of video processing capabilities of said one device,
- select one of a plurality of video processing algorithms for execution by said one device.
A video source device comprising a processor and memory interconnected with said processor, said memory storing instructions which, when executed by said processor, cause said video source device to:
- receive an indication of video processing capabilities of a video sink device;
- and
- based upon:
- (a) said indication;
- and
- (b) an indication of video processing capabilities of said video source device,
- select one of a plurality of video processing algorithms for execution by said video source device.
A video sink device comprising a processor and memory interconnected with said processor, said memory storing instructions which, when executed by said processor, cause said video sink device to:
- receive an indication of video processing capabilities of a video source device;
- and
- based upon:
- (a) said indication;
- and
- (b) an indication of video processing capabilities of said video sink device,
- select one of a plurality of video processing algorithms for execution by said video sink device.
