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.

Adaptive and seamless playback buffer adjustment for streaming content

An electronic device may include a display for displaying image content to a user and dynamic image stabilization circuitry for dynamically compensating the image content if the device is moving unpredictably to help keep the image content aligned with the user's gaze. The electronic device may include sensors for detecting the displacement of the device. The dynamic image stabilization circuitry may include a usage scenario detection circuit and a content displacement compensation calculation circuit. The usage scenario detection circuit receives data from the sensors and infers a usage scenario based on the sensor data. The content displacement compensation calculation circuit uses the inferred usage scenario to compute a displacement amount by which to adjust image content. When motion stops, the image content may gradually drift back to the center of the display.

Dynamic image stabilization using motion sensors

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.

Wireless audio splitter

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).

Individualized adaptive wireless parameter tuning for streaming content

A communication device and method for offloading communications from a first communication network to a second communication network. The offloading decision can be based on one or more utility values and/or one or more utility sum values. The utility values and/or utility sum values can be defined in a communication framework. The communication framework can be, for example, Access Network Discovery and Selection Function (ANDSF) framework. The offloading of communication can be from a Long-term Evolution (LTE) network to a wireless local area network (WLAN), or vice-versa. The communication framework can include, for example, utility, utility sum, positional, movement, signal quality, connection duration, data rate, and/or quality of service (QoS) parameters.

Network discovery and selection using utility information and radio interworking

A communication device and method for offloading communications from a first communication network to a second communication network. The offloading decision can be based on one or more parameters defined in a communication framework. The communication framework can be, for example, Access Network Discovery and Selection Function (ANDSF) framework. The offloading of communication can be from a Long-term Evolution (LTE) network to a Wi-Fi network, or vice-versa. The communication framework can include, for example, positional, movement, signal quality, connection duration, a data rate, and/or quality of service (QoS) parameters.

Systems and methods for network discovery and selection using contextual information

A communication device configured to route communications between one or more out-of-coverage communication devices using one or more proximity services (ProSe). For example, the communication device can be configured as a mobile device-to network relay. The communication device can be configured to route communications associated with one more out-of-coverage communication devices that are serviced by the communication device. The communication device can be configured to utilize Layer 3 routing.

Relay architectures for mobile wireless networks

A communication device and method for crowdsourcing of information from one or more communication devices. The crowdsourced information can be defined by one or more parameters defined in an operational framework. The operational framework can be, for example, an Access Network Discovery and Selection Function (ANDSF) framework. The operational framework can include, for example, positional and/or movement information of the communication device(s), a signal quality of a communication network, a visibility duration of a communication network, data rate information of a communication network, and/or quality of service (QoS) information of a communication network.
