REMOTE PROGRAMMING OF CATV CHANNEL AUTHORIZATION UNIT ABSTRACT OF THE DISCLOSURE Method and apparatus is disclosed for programming a CATV channel authorization unit. In a cable television (CATV) system, a CATV transmitter provides a plurality of CATV system channels to a channel authorization unit which in turn supplies only selected ones of the system channels to a user. The CATV authorization unit determines which selected channels the user will receive by receiv- ing channel authorization data from a CATV system programmer. The channel authorization data is received via an infrared data com- munication link such that programming can be done without physical disassembly of the CATV channel authorization unit and without the system programmer being physically present within the users house- hold. In a further embodiment. the CATV channel authorization unit is also responsive to a user transmitter for determining which of the selected channels the user is presently viewing.
