Abstract
In one embodiment, a localization beacon is inserted into a digital communication signal by a localization device. The resulting modified signal is transmitted to customer premises equipment (CPE). One or more CPE devices monitor incoming signals to detect the presence of a localization beacon. If a localization beacon having certain characteristics is not received, the one or more CPE devices are configured to disable one or more CPE features.
Claims22
A device configured to generate a localization beacon signal to enable or disable one or more services of a customer premise equipment paired to said device, said device being configured for installation proximal to or at a customer premise to serve as an intermediary device located between a head end and the customer premise equipment, said device comprising:
- a first interface configured to receive content signals from a head end;
- a second interface configured to transmit content signals to one or more customer premises equipment;
- computer readable memory;
- a processor configured to generate a digital sequence comprising a localization beacon based on a unique device identifier stored in the computer readable memory, the unique device identifier being associated with a specific pairing between said device and one or more intended customer premises equipment (CPE) to which said device is intended to be paired;
- and
- a variable forward gain stage configured to modulate an amplitude of an original signal received, at the first interface, from the head-end, based on the digital sequence, and to provide a resulting modified signal to the second interface for transmission to the customer premises equipment,
- wherein the customer premises equipment is configured to demodulate the transmitted resulting modified signal to determine a digital sequence modulated thereto and to enable or disable one or more services associated with the customer premises equipment based on the demodulated digital sequence having a unique device identifier specific to customer premises equipment.
4 more elements
A device comprising:
- computer readable memory including data for pairing said device to an intended specific localization device having an interface connected to a head end;
- a processor configured to monitor, from a connected localization device, an input signal for presence of a localization beacon transmitted therefrom and to disable one or more device features of said device if a localization beacon corresponding to a pairing between an intended specific localization device and said device is not detected within the input signal within a detection time period,
- wherein the localization beacon associated with the intended specific localization device comprises a digital sequence based on a unique device identifier associated with the pairing between the intended specific localization device and said device, the digital sequence having been introduced, by the intended specific localization device, via amplitude modulation, into a signal received by the intended specific localization device from the head-end to form the input signal;
- and
- an automatic gain control (AGC),
- wherein a bit rate of the modulated digital sequence introduced by the connected localization device is less than a maximum amount for which the AGC can compensate, whereby the AGC is configured to determine the introduced digital sequence as the received localization beacon based on an adjustment of the received input signal to a level for use by said device.
3 more elements
A system comprising:
- a localization device configured to generate a localization beacon signal to enable or disable one or more services of a connected customer premise equipment paired to the localization device, the localization device being configured for installation proximal to or at a customer premise to serve as an intermediary device located between a head end and the connected customer premise equipment;
- and
- a customer premises equipment (CPE) device configured to monitor an input from a connected localization device for presence of an intended localization beacon, the intended localization beacon comprising a unique device identifier specific to a pairing between an intended localization device and the customer premises equipment, the CPE device being configured to disable one or more features thereof if the received localization beacon specific to a pairing between the intended localization device and the CPE device is not detected within a detection time period,
- wherein the CPE device includes an automatic gain control (AGC),
- wherein the localization beacon comprises a digital sequence to be used for the disabling of the one or more features of the customer premises equipment, the digital sequence being amplitude modulated, by the localization device, into a higher bit rate digital signal to generate the input from the localization device, and
- wherein an amplitude change introduced by the amplitude modulation is less than a maximum amount that can be compensated for by the AGC, whereby the AGC is configured to determine the digital sequence from the localization beacon based on an adjustment of the received input signal to a level for use by said device.
3 more elements
A method for use in a localization device installed proximal to or at a customer premise to serve as an intermediary device located between a head end and a connected customer premise equipment, the method comprising:
- generating a localization beacon signal to enable or disable one or more services of a connected customer premise equipment paired to the localization device, wherein the localization beacon signal generation is based on a unique device identifier stored in computer readable memory of the localization device, the unique device identifier being associated with a pairing between at least one respective intended customer premises equipment (CPE) and the localization device;
- receiving a cable television signal;
- inserting the localization beacon into the cable television signal to generate a modified cable television signal for transmission to the customer premises equipment, wherein the modified cable television signal is generated using a variable forward gain stage that is responsive to a digital sequence generated based on the unique device identifier, the variable forward gain stage creating an amplitude modulated digital sequence having a bit rate that is less than a maximum amount for which an automatic gain control of the customer premises equipment can compensate;
- and
- transmitting the modified cable television signal to the at least one CPE device.
