Abstract
For transmitting delay-critical data in a digital, time division form in an additional channel of a cable television system, the slots of the channel are further divided into smaller mini slots, for the indication of which the same cyclic indication is used as with which the superframes controlling the use of the channel indicate the original slots. A method based on mini slots is compatible with DAVIC 1.0 and 1.1 specifications.
