1. In a method for common transmission of digital source and control data between data sources and sinks being connected by data lines, which includes transmitting the source and control data in a format prescribing a clocked sequence of individual bit groups of equal length, the improvement which comprises:

  • combining a plurality of successive bit groups into a block, and assigning a respective block beginning identification code to a certain bit position within a first bit group of the block;

    defining at least one bit of each bit group, respectively, as a control bit for the transmission of control signals;

    transmitting a control signal bitwise with the control bits of successive bit groups;

    providing a starting identification code being identical for all of the control signals at the beginning of each control signal, whereby the starting identification code of the control signals does not have a fixed relation to the block beginning identification code of each corresponding block; and

    setting a length of the control signals to be less than a number of the control bits present in one block.
