ABSTRACT:
TV cable apparatus wherein a stereo module unit at a user location automatically provides for the presentation of an FM audo channel associated with a particular TV channel. The FM frequency allocations associated with the particular TV channels are stored ina computer memory which may be periodically revised. The cable operator periodically sends out the latest TV channel versus FM channel frequency allocation in an FSK coded data signal which is recognized by the stereo module unit which then proceeds with an updating, if required. The data signal is sent on a normally unused FM channel and in one embodiment if this channel is changed, the apparatus is operable to find the new data channel for channel map updating.
