Patent ID: 7855973

Claim:
A communications method comprising; establishing a data link between a data source and a data recipient via an extended synchronous connection oriented (eSCO) channel between first and second Bluetooth™ devices; determining a quality of the data link, wherein determining a quality of the data link comprises determining a quality of transmission of an audio and/or video source over the data link; and adjusting a transmission interval and a retransmission criterion of the eSCO channel and an error correction coding of the data link responsive to the determined quality of the data link, wherein adjusting a transmission interval and a retransmission criterion of the eSCO channel and an error correction coding of the data link responsive to the determined quality of the data source comprises adjusting the transmission interval and the retransmission criterion of the eSCO channel and the error correction coding of the audio and/or video source responsive to the determined quality of transmission of the audio and/or video source over the data link, wherein the audio and/or video source comprises a vocoder and wherein adjusting the transmission interval and the retransmission criterion of the eSCO channel and the error correction coding of the audio and/or video source responsive to the determined quality of transmission of the audio and/or video source over the data link comprises adjusting the transmission interval and the retransmission criterion of the eSCO channel and an error correction coding applied to an output of the vocoder while maintaining a fixed rate of data transfer of the output of the vocoder to the data recipient.
