Low latency screen mirroring

A sink device, comprising:

• a communications interface;
• a memory comprising executable code;
• and
• at least one processor communicatively coupled to the communications interface and the memory,
• wherein the at least one processor and the memory are configured to:
• receive a plurality of graphics domain frames comprising no rendered graphics from a source device via the communications interface,
• wherein each of the graphics domain frames comprises one or more graphics command tokens, and the plurality of graphics domain frames are compressed by using an adaptive compression pipeline to select a compression technique from (a) scalable texture streaming configured to divide a frame into a plurality of stages that are smaller than the frame and transmit the plurality of stages in sequence, (b) frame-based prediction using differentially coded locations to identify portions of two consecutive frames that contain different data from one another, (c) frame dropping, and (d) data compression;
• and
• display a rendered image of at least some of the plurality of graphics domain frames in time synchronization with a corresponding rendered image displayed at the source device with non-perceptible screen-to-screen latency by refraining from displaying one or more of the plurality of graphics domain frames based on a timestamp of each of the plurality of frames.

A method of screen mirroring operable at a source device, comprising:

• capturing a plurality of graphics domain frames of screen content, each of the frames comprising one or more graphics command tokens, wherein the plurality of graphics domain frames comprise no rendered graphics;
• compressing the plurality of graphics domain frames by using an adaptive compression pipeline to select a compression technique from (a) scalable texture streaming configured to divide a frame into a plurality of stages that are smaller than the frame and transmit the plurality of stages in sequence, (b) frame-based prediction using differentially coded locations to identify portions of two consecutive frames that contain different data from one another, (c) frame dropping, and (d) data compression, based on a plurality of characteristics of the frames to facilitate screen mirroring at a sink device with non-perceptible screen-to-screen latency;
• transmitting the compressed frames via a communications interface of the source device to the sink device;
• and
• displaying a rendered image of the frames in time synchronization with a corresponding rendered image of the compressed frames displayed at the sink device with non-perceptible screen-to-screen latency.
