Abstract:
1. A communication system, comprising: a receiving unit; a transmitting unit operatively coupled to the receiving unit via a first channel, the transmitting unit being configurable to transmit a first data stream to the receiving unit in the first channel, the first data stream containing communications data and control data, wherein the transmitting unit transmits the first data stream so that communications data is transmitted in a grouping that complies with an asynchronous protocol and the control data is transmitted within a segment of the first data stream that is specified as unused for communications data according to the asynchronous protocol; wherein the receiving unit extracts communications data from the grouping in the first data stream and extracts control data from the segment in the first data stream; and a device coupled to the receiving unit, wherein the device is configured to exchange communications data with the receiving unit over a second channel in a second data stream conforming to the asynchronous protocol.
