A method or apparatus for multi-channel audio data control using plural mobile devices comprising steps of detecting user presence through assigned frequency, transmitting audio data to the nearest device from the user based on user presence information, and recognize user gesture to control the audio data. A remote controller held by the user may also have a priority to control audio data.

Method and apparatus for controlling audio data by recognizing user gesture and position using multiple mobile devices

The present invention relates to a method of synchronizing playback of a digital content between connected devices, the method including: receiving a playback delay time list or a playback sync timestamp from a master device during a playback duty cycle; calculating a playback delay time correction amount by referring to the playback delay time list in order to synchronize playback between a plurality of connected devices including the master device; correcting a playback sync timestamp used in the playback synchronization according to the playback delay time correction amount; and playing a digital content according to the corrected playback sync timestamp, and the slave device applies a different playback delay time in consideration of the slave device's own state, so that the playback of the digital content may be synchronized between the devices connected through the network.

Method of synchronizing playback of digital content between plurality of connected devices and device using the same

The present disclosure relates to a method of synchronizing playback of video and audio of a digital content. The method includes at least: transmitting, by a plurality of devices connected to a network, a video playback delay time, an audio playback delay time, and position information, to a master device; receiving a video playback delay time list or a video playback sync timestamp during a video playback duty cycle; receiving at least one of a virtual synchronization audio delay distance, audio delay distances of the connected devices, a sweet spot position, an audio playback delay time list, and an audio playback sync timestamp during an audio playback duty cycle; determining a video playback delay time correction amount, and correcting the video playback sync timestamp in consideration of the video playback delay time correction amount; and correcting the audio playback sync timestamp with the audio playback delay time correction amount.

Method of synchronizing playback of video and audio of digital content and device using the same

A multi-dimensional audiogram providing apparatus includes a processor; and a memory connected to the processor, and the memory stores program instructions that, when executed, cause the processor to output a pure tone audiogram related to a hearing threshold for a subject measured in N frequency on a first surface of a polyhedron; to define a plurality of harmonic templates by rearranging the N frequency bands into a frequency set including a plurality of element frequencies; to calculate a standard deviation of hearing thresholds of a plurality of element frequencies to calculate a harmonic template instability degree; to output the calculated harmonic template instability degree on a second surface of the polyhedron; to calculate an average of the hearing thresholds of the plurality of element frequencies to calculate a harmonic template hearing; and to output the calculated harmonic template hearing on a third surface of the polyhedron.

A multiple power mode amplifier provides a low and a high power mode without using switches. This amplifier may be used in radio frequency (RF) applications such as mobile telephones, pagers, portable digital assistants, and wireless e-mail devices. In the low power mode, the power consumption of the amplifier is reduced, which will increase operation time, especially important for battery-operated devices. In one implementation, the amplifier includes a number of impedance matching network units (, and), impedance transformer (), and a power stage (). An implementation provides further power consumption savings by modulating a bias of an amplifier stage.
