ABSTRACT:
Apparatus is disclosed for use in a digital signal transmission or recording system, particularly for video signals where, as is customary, the number of digital signals (i.e., digital words) is reduced (for example, by a factor of 2) prior to transmission or recording. The apparatus is operable to determine when a digital word fed to an input filter has a characteristic similar to that of a filtered word so that such a word can bypass the input filter and be transmitted or recorded without further filtering. This is achieved by monitoring the words input to the input filter and then operating a bypass around the input filter when the monitoring circuit detects that an input word has a characteristic similar to a filtered word.
