This disclosure describes systems, methods, and devices related to label based isochronous connection update. A central Bluetooth low energy (BLE) device may send a plurality of labels to a peripheral BLE device during a setup of a BLE communication to notify the peripheral BLE device of one or more labels to be used during the BLE communication. The central BLE device may determine a channel variation between the central BLE device and the peripheral BLE device. The central BLE device may send a first label to the peripheral BLE device to indicate an isochronous (ISO) parameter update that will occur at a first time offset based on the channel variation. The central BLE device may implement the isochronous parameter update at the first time offset based on the channel variation.

In some aspects, the present disclosure provides a method for communicating audio data. In one example, the method includes determining whether a condition for each transport opportunity on an audio channel is met based on an audio sample rate and a channel rate of the audio channel. For each transport opportunity, upon determining that the condition is met for the transport opportunity, the method also includes transmitting audio sample data over the transport opportunity or receiving audio sample data at the transport opportunity.

Provided are a topology switching method based on isochronous channel, an apparatus, a system and a storage medium. The method is applied to a first central slave device. There are a plurality of first isochronous channels between the first central slave device and a master device, and there is a first communication channel between the first central slave device and a peripheral slave device. The method includes: sending, by first central slave device, first isochronization information to peripheral slave device through the first communication channel, where the first isochronization information includes a channel parameter of first isochronous channel, so that peripheral slave device starts data transmission with master device according to the channel parameter of first isochronous channel; and stopping, by first central slave device, data transmission with master device through the first isochronous channel, before peripheral slave device starts data transmission with master device.

In some examples, a transport agnostic source includes a streaming device to stream video on diverse transport topologies including isochronous and non-isochronous transports. In some examples, a transport agnostic sink includes a receiving device to receive streamed video from diverse transport topologies including isochronous and non-isochronous transports.

Disclosed herein are systems and techniques for slave-to-slave communication in a multi-node, daisy-chained network. Slave nodes may provide or receive upstream or downstream data directly to/from other slave nodes, without the need for data slots first to route through the master node.

A semiconductor device includes a reception data input terminal configured such that reception data, which is serial data, is input; a transmission data output terminal configured such that transmission data, which is serial data, is output; and a communication part configured to receive the reception data and transmit the transmission data, wherein the communication part includes: a counter; and a synchronization part configured to monitor the transmission data if the semiconductor device is other than a target device set in the reception data, and reset a count by the counter upon detecting a stop bit and a start bit at frame switching in the transmission data.

Provided is a method and apparatus for wirelessly transmitting Universal Serial Bus (USB) application data by using an Enhanced Distributed Channel Access (EDCA) scheme that uses one or more Access Channels (ACs) having different priorities. The method includes receiving one or more USB application data from an USB application, dynamically assigning an AC through which the USB application data is to be transmitted, and transmitting the USB application data through the assigned AC.

In some examples, a transport agnostic source includes a streaming device to stream video on diverse transport topologies including isochronous and non-isochronous transports. In some examples, a transport agnostic sink includes a receiving device to receive streamed video from diverse transport topologies including isochronous and non-isochronous transports.

The invention describes a method and a computer network for fault tolerant message transmission. Nodes of the network are connected to form a ring network. Nodes in the network form a summation group. For transmitting messages from the nodes of the summation group to a switch edge, nodes of the summation group generate and send summation frames. If a node participating in the summation group determines the non-arrival of a summation frame, it generates first recovery frame, inserts its message into said recovery frame, and sends this first recovery frame in the direction of the summation frame, which it was expecting. After sending the first recovery frame, it generates a second recovery frame, inserts its messages into said second right direction recovery frame, and sends said second right direction recovery frame to the switch.

Methods, integrated circuits and computer-readable media for communicating back-channel data over a data link by modulating the phase or frequency of a clock signal of a data signal transmitted over the data link. Slow modulation of the clock signal allows it to be detected and extracted by a receiver without affecting the integrity or bit rate of the data signal. Some embodiments allow the functionality to be implemented without the use of extra hardware in the transmitter or receiver or either.
