Abstract:
Aspects of the present disclosure relate to graphics domain transmission methods that utilize an adaptive compression pipeline to achieve low latency screen mirroring between a source device and a sink device. A source device captures a plurality of graphics domain frames, each of the graphics domain frames including one or more graphics command tokens. The source device utilizes an adaptive compression pipeline to compress the graphics domain frames based on one or more characteristics of the frames, and the adaptive compression pipeline is configured to perform at least one of scalable texture streaming, frame-based prediction, frame dropping, or data compression. The source device transmits the compressed frames to a sink device, and displays a rendered image of the graphics domain frames in time synchronization with a corresponding rendered image of the compressed frames displayed at the sink device.
