Abstract
A system is provided for evaluating a subcode of a digital information transmission. Such transmission occurs in particular in the context of scanning of compact disc recordings. Data blocks of a digital signal including a subcode of several segments and associated with a large redundancy are present as an additional signal, and these data blocks are separately evaluated with respect to each segment of the subcode corresponding to a data block. The digital signals are preferably audio or video signals. It is possible to intermediately store the data of each segment and to continuously compare the data of each segment of a preceding intermediately stored data segment. The preceding intermediately stored data segment can be the immediate sequential predecessor of the data segment under consideration. The segments of a data block can be evaluated successively according to a time multiplexing method.
