2. The remote control system of claim 1, wherein the master controller is combined with a satellite radio receiver and display unit, a home theater receiver and display unit, or other remotely controlled equipment.

3. The remote control system of claim 1, further comprising:

a repeater/localizer for receiving the remote control code request message, adding a location code to the remote control code request message and transmitting the remote control code request message with the added location code, wherein the master controller retrieves the requested remote control code based on the location code.

4. The remote control system of claim 1, wherein there are multiple remote control units, with each remote control unit generating an identifier code to include with the remote control code request message and the master controller transmitting the requested remote control code message with the identifier code.

5. The remote control system of claim 4, wherein the identifier code is generated using a pseudorandom number.

6. The remote control system of claim 1, wherein the remote control unit or the master controller generate a cyclic redundancy check (CRC) to include with transmitted messages, and the remote control unit or the master controller analyzes received messages for correct CRC and transmits an error message if the CRC is incorrect.

7. The remote control system of claim 6, wherein the remote control unit or the master controller detects CRC error messages and operates an error function.

8. The remote control system of claim 7, wherein the error function operated by the remote control unit includes retransmitting the remote control code request message, displaying an error message on a graphical display or sounding an audible warning on an audio transmitter and the error function operated by the master controller includes transmitting an error message.

9. The remote control system of claim 1, wherein the remote control unit operates a timer to determine if the remote control code request message has been processed by the master controller and operates an error function after a predetermined time interval, and the error function operated by the remote control unit includes retransmitting the remote control code request message, displaying an error message on a graphical display or sounding an audible warning on an audio transmitter.

10. The remote control system of claim 1, wherein the remote control unit displays program information received from the master controller on a graphical display or sounds an audible warning on an audio transmitter.

11. The remote control system of claim 1, wherein the remote control unit receives and transmits using infrared (IR) or radio frequency (RF) signals and the master controller receives and transmits using IR or RF signals.

12. The remote control system of claim 11, wherein the IR signal uses about a 38 kHz or about a 455 kHz carrier frequency.

13. The remote control system of claim 3, wherein the remote control unit receives using radio frequency (RF) signals and transmits using infrared (IR) or RF signals, the repeater/localizer receives using IR or RF signals and transmits using RF signals, and the master controller receives and transmits using RF signals.

14. The remote control system of claim 13, wherein the IR signal uses about a 38 kHz or about a 455 kHz carrier frequency.

15. A method of operating a remote control system, comprising:

storing in a master controller a plurality of remote control codes for a plurality of remotely controlled equipment;

transmitting from a remote control unit a remote control code request message;

receiving the remote control code request message;

retrieving in the master controller the requested remote control code;

transmitting from the master controller the requested remote control code;

receiving in the remote control unit the requested remote control code;

converting in the remote control unit the requested remote control code into a plurality of remote control commands for controlling at least one of the plurality of remotely controlled equipment;

storing in the remote control unit the plurality of remote control commands; and

transmitting at least one of the plurality of remote control commands to control at least one of the plurality of remotely controlled equipment,

wherein each remote control code contains the plurality of remote control commands for controlling at least one of the plurality of remotely controlled equipment.

16. The method of operating a remote control system of claim 15, wherein the step of storing in a master controller a plurality of remote control codes for a plurality of remotely controlled equipment includes storing in a master controller a plurality of remote control codes for a plurality of remotely controlled equipment and at least one location code corresponding to a location of at least one of the plurality of remotely controlled equipment, the step of receiving the remote control code request message includes receiving in a repeater/localizer the remote control code request message, transmitting from the repeater/localizer the remote control code request message with a location code corresponding to a location of the repeater/localizer, and receiving in the master controller the requested remote control code message with the location code corresponding to a location of the repeater/localizer, and the step of retrieving in the master controller the requested remote control code includes retrieving in the master controller the requested remote control code based on the location code corresponding to a location of the repeater/localizer,
