Resolution-independent dither sample insertion for audio transmissions

摘要

Methods, systems, and apparatuses are provided for resolution-independent dither sample insertion for audio transmissions. Audio transmitters transmit audio data streams to audio receivers. Data inactivity in the data stream triggers the audio receivers to enter power-saving/sleep modes in which synchronization with the audio transmitters is lost thus requiring time consuming resynchronization. Inactivity such as silence or zero-value data is detected in a data stream. Upon detection, a dither sample is inserted into the data stream and transmitted to the audio receiver to prevent the loss of synchronization. The dither sample may have a negative value and be formatted for resolution-independence with respect to the audio receiver.

1. A method, comprising:
monitoring a data stream provided to transmitting logic; determining that the monitored data stream indicates inactivity; and transmitting a dither sample by the transmitting logic in response to said determining that the monitored data stream indicates inactivity, the dither sample comprising a negative value.
