Abstract: In an embodiment, a first media presentation session is established between a first Source and the Sink, and a second media presentation session between a second Source and the Sink. First and second media streams are streamed to the Sink by the first and second Sources, respectively. The Sink presents the first and second media streams in respective portions of a display screen, and detects user input at the Sink that is indicative of a trigger to transfer data originated from the first Source to the second Source. The Sink coordinates with one or both of the first Source and the second Source to facilitate the data to be delivered to the second Source in response to the detection. As a result of the coordination, the second Source receives the first Source-originated data (e.g., from the first Source directly, or via the Sink).

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.
