Prerecorded audio or video information signals including address data indicating the location of synchronized signals from a plurality of synchronized sources are supplied to a single separation circuit via a switching circuit. The separation circuit, selectively connected to one of the signal sources via the switching circuit, separates the address data from the audio or video information of the connected signal source. A register connected to the separation circuit receives the separated address data which constantly updates the register contents. At least one counter is reset to the contents of the register each time a newly selected signal source is connected to the separation circuit to load the address data of the previously connected signal source into that counter. At regular intervals one binary increment is added to the counter address data so that the counter count value corresponds to the address data of the previously connected signal source. The output of the register is a representation of the address of the signal source that is connected to the separation circuit at any instant of time.
A circuit arrangement for use with a plurality of synchronized sources of prerecorded signals including information data which occur synchronously with a common time base in the plural synchronized sources and address data indicating the location of said information data with respect to time, comprising:
Apparatus for keeping track of address locations of plural synchronized sources of prerecorded signals including information data which occur synchronously with a common time base in the plural synchronized sources and address data indicating the location of said information data with respect to time, comprising:
