A sink device is configured to establish a Bluetooth connection with a source device. The sink device receives a transmission from the source device that includes a plurality of data blocks, an item of check information, and a plurality of parity blocks during a transmission time duration. The sink device determines, prior to receiving an entirety of the transmission, whether at least one of received data blocks includes an error based on at least the item of check information and, when the at least one of the received data blocks includes the error and prior to receiving all of the plurality of parity blocks, the sink device performs an error correction operation on a first one of the received data blocks based on a first one of the parity blocks.

A mobile device includes a display, at least one sensor, and a wireless transceiver. The mobile device also includes control circuitry coupled to the display, the at least one sensor, and the wireless transceiver. The control circuitry is configured to obtain content primitives from the at least one sensor, to perform content provisioning operations to obtain content based at least in part on the content primitives, and to display the obtained content on the display, wherein at least some of the content is virtual content. In response to a bandwidth condition of the wireless communication channel being less than a threshold, the control circuitry is configured to perform adjusted content provisioning operations that involve increasing an amount of image processing operations performed by the mobile device to obtain the content.

Methods and apparatus for virtual channel allocation within an electronic device. In one exemplary embodiment, the device is a consumer electronics device having multiple camera sensors uses a modified high-speed protocol (e.g., DisplayPort Multi-Stream Transport (MST) protocol) to process camera data via one or more virtual channels. Unlike traditional solutions which rely on an intelligent source device to manage a network of devices, the present disclosure describes in one aspect a network of nodes internal to a consumer electronic device that is managed by the sink node (i.e., a “smart sink”). Additionally, since the full suite of protocol (e.g., DisplayPort) capabilities are unnecessary for certain design scenarios, certain further disclosed simplifications improve performance for sink nodes having very modest capabilities.

Methods and apparatus for communicating audio packets with ultra-low latency at high data rates from an audio source device to one or more audio output devices over a wireless personal area network (WPAN) connection, such as via a Bluetooth connection. Latency is reduced by using time-efficient audio coding and decoding, limited retransmissions, reduced time and frequency of acknowledgements, and by combining Bluetooth Classic (BTC) packets for downlink audio and downlink control with Bluetooth Low Energy (BTLE) packets for uplink control, uplink acknowledgements, and inter-device wireless communication. The number of retransmissions and packet concealments per frame cycle can be limited to an upper threshold number to satisfy a low latency requirement.

A display system includes a host device that provides source data to a display. The source data includes one or more data-centric blocks free from a fixed-frame size imposition, fixed-frame rate imposition, or both from the display. Further, the source data includes presentation data. The display system includes a display that receives the source data, decodes the source data to discern a presentation time, a presentation positioning, or both for the presentation data. Further, the display presents the presentation data according to the presentation time, the presentation positioning, or both.

An electronic device selectively couples a head with links in a graphics processing unit to a currently selected display port in a pair of display ports. During operation, control logic in the electronic device monitors a pair of configuration signals from the pair of display ports, where the pair of configuration signals correspond to physical connections to the pair of display ports. Then, the control logic determines a selection control signal based on the monitored pair of configuration signals, a policy setting and a default display port, where the selection control signal specifies the currently selected display port. Moreover, the control logic provides the selection control signal to a multiplexer in the electronic device. Next, the multiplexer selectively couples the head with the links in the graphics processing unit to the currently selected display port based on the selection control signal.
