摘要： A system and method for routing communication to a common audio output device connected to each of two or more audio signal source devices. For each of the two or more audio signal source devices, a set of inputs are assessed. The set of inputs include: an operational state of the audio signal source device, an activity the audio signal source device, an audio-producing application being executed by the audio signal source device, and a degree of user activity with the audio-producing application being executed by the audio signal source. At a point in time, an audio routing score is generated for each of the two or more audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the two or more audio signal source devices to the audio output device, based on the audio routing score for each of the two or more audio signal source devices.

摘要： A system and method for peer-to-peer communications is disclosed. A first wireless device receives a message from a second wireless device identifying communication requirements of a point-to-point communication involving the second wireless device. The first wireless device determines whether the second wireless device's communication requirements can be satisfied based on communication resources already committed for other communications. When the communication requirements of the second wireless device can be satisfied, the first wireless device generates a time sharing schedule to be used by the first and second wireless devices based on the already-committed communication requirements and the second device's communication requirements. The time sharing schedule may include a first portion for broadcast communication among a group of devices to which the first and second wireless devices belong, and a second portion for the point-to-point communications of the second wireless devices.

摘要： A source device executing the application can transmit the streaming content to the playback device. The size of the buffer can be changed during the playback of streaming content. To perform the change seamlessly, embodiments can cause the application to provide the streaming content at an increased or decreased rate, depending on how the size of the playback buffer is to be changed. The new buffer size (i.e., smaller or larger amount) can provide improved playback of the streaming content, e.g., based on a latency-reliability tradeoff as determined using various factors (e.g., quality of connection between the devices). The changed rate for providing the streaming content can be achieved by slowing down or speeding up a clock signal that is provided to the application.

摘要： A source device can transmit initial streaming content to a playback device (e.g., wireless ear buds) using first settings and measure playback performance of the content at a plurality of times. The measured performance values can relate to a quality of communication of the initial streaming content between the source device and the playback device, e.g., relating to packet loss, retransmission rates and patterns, fluctuations in a playback (jitter) buffer, and/or other values. The measured performance values can be used to determine one or more second settings to be used for a playback of subsequent streaming content between the source device and the playback device. In this manner, each source device can account for variations in communication behavior specific to a user (e.g., due to differences in body type as electromagnetic waves travel through the body when a source device is in a pocket).

摘要： A host device communicating with a plurality of accessory devices transmits audio data packets via a broadcast channel to the plurality of accessory devices. When one of the plurality of accessory devices determines an audio data packet has not been received, the accessory device sends a negative-acknowledgement signal (NACK) via a unicast channel. The NACK indicates that the at least one of the accessory devices did not receive at least one audio data packet. The host device retransmits the at least one audio data packet indicated as not being received via the broadcast channel to the plurality of accessory devices. Other aspects are also described and claimed.
