A method is disclosed for switching connections of Bluetooth headsets. The method includes indicating, on a user interface of the first Bluetooth device, (i) the first Bluetooth device has a first Bluetooth connection with a Bluetooth headset, and (ii) a second Bluetooth device has no Bluetooth connection with the Bluetooth headset. Also, the method includes receiving user input to establish a second Bluetooth connection between the second Bluetooth device and the Bluetooth headset. Further, the method includes sending a message to the Bluetooth headset. The message includes a unique device identifier of the second Bluetooth device. The message represents a command for the Bluetooth headset to establish the second Bluetooth connection with the second Bluetooth device. Responsive to the message, the Bluetooth headset (i) releases the first Bluetooth connection with the first Bluetooth device and (ii) establishes the second Bluetooth connection with the second Bluetooth device.

Connection switching for Bluetooth headsets

Connection switching for Bluetooth headsets is disclosed. A Bluetooth headset includes a Bluetooth transceiver configured to receive a message from a first Bluetooth device over a first Bluetooth connection with the first Bluetooth device. The message includes a command to establish a second Bluetooth connection with a second Bluetooth device. The Bluetooth headset also includes a processor configured to cause the Bluetooth transceiver to (i) release the first Bluetooth connection and then (ii) establish the second Bluetooth connection with the second Bluetooth device responsive to the Bluetooth transceiver receiving the message. Computer-readable media for the Bluetooth devices is also disclosed.

A source communication device includes a source network clock to control timing of communicating with other devices in a network, a source streaming clock associated with processing of audio or video data, a time stamp generator to generate a time stamp that includes a source network clock value and a source streaming clock value, and a time stamp insertion mechanism that incorporates the time stamp into a data unit that is to be transmitted to one of the other devices in the network. A sink communication device includes a sink network clock synchronized with the source network clock, a sink streaming clock associated with processing of audio or video data, and a sink time stamp mechanism to compare a sink streaming clock value with the source streaming clock value, and adjust the sink streaming clock based on the comparison.

The present invention relates to a device and a method for presentation of information on a display. The method performs obtaining information to be presented on an information presentation unit, presenting information on the information presentation unit, presenting a selection area on the information presentation unit, determining mode for updating information on information presentation unit, in dependence of user input, detecting a rotational motion around an axis of rotation of an information presentation device, and providing either the selected area at an updated position on the information presentation unit or the presented information at an updated position on the information presentation unit, in dependence of the detection of rotational motion and in dependence of obtained user input, enabling the selection area or the information to rotate according to detected rotational motion around an axis of rotation of the information presentation device.

Information presentation device

The present invention relates to a method and a device for presentation of content-rich information portions and content-poor information portions, such as list type information on a display. The method performs obtaining of information for presentation on an information presentation unit, monitors a rotational motion around an axis of rotation of an information presentation device, monitors the position of a seam of the information presentation unit, and presents information on the information presentation unit in dependence of the monitored rotational motion and in dependence of the monitored position of the first and second ends, such that content-rich information is presented on the information presentation unit and that content-poor information is presented across the first and second ends of the information presentation unit.

Embodiments include a method of communicating an audio stream from an audio source terminal to a plurality of speaker terminals. A broadcast channel is established for communication from an audio source terminal to a plurality of speaker terminals. A plurality of bidirectional point-to-point control channels are established for controlling wireless communications between the audio source terminal and the speaker terminals, where each of the point-to-point control channels interconnect the audio source terminal and a different one of the speaker terminals. An audio stream is transmitted as a sequence of blocks of audio data in messages from the audio source terminal through the broadcast channel for receipt by all of the speaker terminals. A quality of reception feedback message is received at the audio source terminal from individual ones of the speaker terminals through respective ones of the point-to-point control channels. The audio data messages are adapted for transmission from the audio source terminal through the broadcast channel in response to the quality of reception feedback message.

Wireless audio data distribution using broadcast and bidirectional communication channels

A method of managing audio data received by an accessory device from an electronic equipment over a local wireless interface link includes buffering the audio data; feeding the buffered audio data to a decoder and detecting a decoder under run. After the detection of a decoder under run, the method restarts the feed of audio data to the decoder when an amount of buffered audio data is equal to or greater than a dynamically adjustable threshold amount of audio data.
