Methods and apparatus for latency control in display devices

摘要

Various methods, systems, and apparatus for implementing aspects of latency control in display devices are disclosed. According to aspects of the disclosed invention, a source device commands a display device to minimize the delay between the time that image data enters the display device and the time that it is shown on the display device. In one embodiment, the source device transmits data to the display device that specifies whether the display device should time optimize the image data, such as by transmitting a data packet for this purpose either with the image data or on an auxiliary communication link. In another embodiment, the source device and the display device are coupled via an interconnect that comprises multi-stream capabilities, and each stream is associated with a particular degree of latency optimization.

主权项

1. A method for controlling latency in a display device, comprising:
transmitting audiovisual data from a source device to said display device via a first communication link; and transmitting a latency reduction signal from said source device to said display device, wherein said latency reduction signal identifies one or more processing stages to be performed in said display device based on information received at said source device from said display device relating to a plurality of processing stages available in said display device, said one or more processing stages selected by said source device to achieve a desired degree of latency reduction.
