Dual-channel real-time communication

Abstract

A communication circuit includes a dual-channel coder having an unencoded data communication port, a first encoded data communication port, and a second encoded data communication port. The dual-channel coder is operative to translate between unencoded data at the unencoded communication port and corresponding encoded data at both the first encoded data port and at the second encoded data port The circuit further includes a real-time channel interface for connection to a real-time communication channel and operatively connected to the first encoded data tort of the coder. The real-time communication channel has a first latency of a guaranteed maximum for a data element to travel between ends of the real-time communication channel. The circuit further includes a best-efforts channel interface for connection to a best-efforts communication channel and operatively connected to the second encoded data port of the coder. The best efforts communication channel has a second latency with an allowable time for a data element to travel between ends of the best-efforts channel that is longer than the guaranteed maximum time.
