Abstract
A data link, e.g., an audio and/or video data link, is established from a data source, such as an audio and/or video encoder, to a data recipient via an adjustable synchronous radio channel, such as an extended Synchronous Connection-Oriented (eSCO) channel between first and second Bluetooth™ devices. A quality of the data link is determined. A transmission interval and a retransmission criterion of the adjustable synchronous radio channel and an error correction coding of the data link are adjusted responsive to the determined quality of the data link to, for example, maintain a fixed information transfer rate over the data link. The transmission interval and retransmission criterion of the adjustable synchronous radio channel and an error correction coding of the data link may be adjusted by communicating channel parameters between the first and second devices over the radio channel to adjust the transmission interval and the retransmission criterion of the adjustable synchronous radio channel.
