Abstract: A communication system, source and destination ports of the communication system, and methodology is provided for transporting data in one of possibly three different ways. Data is transported across the network at a frame sample rate that can be the same as or different from the sample rate or master clock within the source port or the destination port. If the sample rate of the source port is known, the sample rate of the destination port can be created using a PLL within the destination port and simply employing a phase comparator in the source port. The phase comparator forwards the phase or frequency difference of the network transfer rate and the source sample rate to the destination port, which then generates a local clock equivalent to the source which then compiles audio data being played at the same rate in which it was sampled at the source. Where economically feasible, sample rate conversion can be used at the source.

Abstract: A method for common transmission of digital source and control data between data sources and sinks being connected through data lines, includes transmitting the source and control data in a format specifying a clocked sequence of individual bit groups of equal length. In these bit groups, certain bit positions are each reserved for the source and control data and the bit positions reserved for the source data form a cohesive region within one bit group. The region of a bit group reserved for the source data is subdivided into a plurality of partial bit groups of equal length. The source data assigned to each partial bit group are allocated to a certain data source/data sink as a function of the control data.
