Abstract: A source electronic device may include first interface circuitry that transmits a data packet over a wireless link to a sink electronic device to present the data packet as part of a video stream. The source electronic device may also include encoder circuitry that encodes the data packet for transmission through the wireless link and a feedback path communicatively coupling the encoder circuitry directly to the first interface circuitry. The feedback path may transmit one or more feedback signals from the first interface circuitry to the encoder circuitry, bypassing a network layer, an encoder driver, or both. The encoder circuitry, the first interface circuitry, or both may adjust one or more transmission parameters associated with transmitting the data packet over the wireless link, based on the one or more feedback signals.

Abstract: A method for a communication protocol that includes wideband access for low latency audio. A source device and a sink device establish a wireless communication link. The protocol for communicating via the wireless communication link includes a frame having a first deterministic portion and a second opportunistic portion. The source device transmits during the first deterministic portion of the frame, first data to the sink device. The source device determines whether a predetermined condition associated with the wireless communication link is satisfied. When the predetermined condition is satisfied, the source device transmits, during the second opportunistic portion of the frame, second data to the sink device.
