First Claim
1. A cable system wherein an array of TV and FM signals are provided by an operator to a user comprising:
- (A) means for assigning one or more FM channels to a particular TV channel and for varying said assignment, if desired, said assignment constituting a TV-FM channel map;
(B) means for transmitting to said user, along with said array of signals, a data signal, said data signal being transmitted on a predetermined FM frequency;
(C) said data signal including said channel map assignments;
(D) a stereo module unit for operation at the location of said user;
(E) said stereo module unit including means operable to receive and extract said data signal from said array of signals and to store said channel map assignments and further operable that, when a user tunes to a particular TV channel, any assigned FM channel associated with said particular TV channel will be selected for audio presentation.

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.
