1. A system for distributing program services by transmitting said program services in the form of a plurality of audio/video signals from a headend facility to a plurality of receiving devices, the system comprising: a primary device for receiving and distributing the plurality of audio/video signals from said headend facility to at least one remote device and including a wireless accessory for wireless communication with said at least one remote device to distribute said audio/video signals, wherein the primary device, in response to receiving a proximity detection request from said headend facility, determines a distance between the primary device and each remote device via the wireless accessory to identify each remote device with said determined distance from said primary device exceeding a predetermined distance, communicates said each identified remote device to said headend facility to facilitate disablement of said program services to said each identified remote device, and selectively disables said program services to said each identified remote device in accordance with direction from said headend facility. 2. The system of claim 1, wherein when the primary device determines the distance to be outside of the predetermined distance, the corresponding remote device discontinues receiving signals. 3. The system of claim 1, wherein the primary device transmits a signal indicating the presence or absence of the at least one remote device within the predetermined distance. 4. The system of claim 3, wherein when the headend facility receives the signal indicating the absence of the at least one remote device, the headend facility discontinues program services to the at least one remote device. 5. The system of claim 4, wherein the headend facility discontinues program services by at least one of no longer transmitting signals directly from the headend facility and sending a discontinue signal to the primary device directing the primary device to no longer communicate with the at least one remote device. 6. The system of claim 1, wherein the primary device includes a set-up procedure that includes detecting and storing the distance between the primary device and the at least one remote device, wherein the detected distance becomes the predetermined distance. 7. The system of claim 1, wherein the primary device determines the distance by using a receive signal strength indication measurement. 8. The system of claim 1, wherein the primary device determines the distance by using ultrawideband (UWB) communications with the at least one remote device. 9. A system for distributing program services by transmitting said program services in the form of a plurality of audio/video signals from a headend facility to a plurality of receiving devices, the system comprising: a primary device for receiving and distributing the plurality of audio/video signals from said headend facility, the primary device comprising: a plurality of tuners, each tuner for providing an audio/video signal; anda wireless accessory for wireless communication to distribute said audio/video signal from each said tuner; andat least one remote device in wireless communication with the primary device to receive said program services, the at least one remote device for selecting and receiving a selected audio/video signal from at least one of the plurality of tuners and the headend facility;wherein the primary device, in response to receiving a proximity detection request from said headend facility, determines a distance between the primary device and each said remote device via the wireless accessory to identify each remote device with said determined distance from said primary device exceeding a predetermined distance, communicates said each identified remote device to said headend facility to facilitate disablement of said program services to said each identified remote device, and selectively disables said program services to said each identified remote device in accordance with direction from said headend facility. 10. The system of claim 9, wherein when the primary device determines the distance to be outside of the predetermined distance, the corresponding remote device discontinues receiving signals. 11. The system of claim 9, wherein the primary device transmits a signal indicating the presence or absence of the at least one remote device within said predetermined distance. 12. The system of claim 11, wherein when the headend facility receives the signal indicating the absence of the at least one remote device, the headend facility discontinues program services to the at least one remote device. 13. The system of claim 12, wherein the headend facility discontinues program services by at least one of no longer transmitting signals directly from the headend facility and sending a discontinue signal to the primary device directing the primary device to no longer communicate with the at least one remote device. 14. The system of claim 9, wherein the primary device includes a set-up procedure that includes detecting and storing the distance between the primary device and the at least one remote device, wherein the detected distance becomes the predetermined distance. 15. The system of claim 9, wherein the primary device determines the distance by using a receive signal strength indication measurement. 16. The system of claim 9, wherein the primary device determines the distance by using ultrawideband (UWB) communications with the at least one remote device.
