Use of television satellite signals to determine location

摘要

Various arrangements are directed to locating a television receiver. Multiple tuners of the television receiver may be simultaneously tuned to different television distribution satellites to receive timing signals. Using these timing signals, the location of the television receiver may be determined. Based on a comparison between a stored, expected location of the television receiver and the determined location, the functionality of the television receiver may be adjusted.

主权项

1. A television receiver comprising:
a plurality of tuners comprising a first tuner and a second tuner; one or more processors; a memory communicatively coupled with and readable by the one or more processors and having stored therein processor-readable instructions which, when executed by the one or more processors, cause the one or more processors to:
tune the first tuner of the plurality of tuners to receive a first television channel transponder stream from a first television distribution satellite of a plurality of television distribution satellites;tune the second tuner of the plurality of tuners to receive a second television channel transponder stream from a second television distribution satellite of the plurality of television distribution satellites, wherein:
the second tuner is tuned to the second television channel transponder stream while the first tuner is tuned to the first television channel transponder stream;determine a location region of the television receiver using the first television channel transponder stream and the second television channel transponder stream;compare the location region of the television receiver to an approved locally-stored location of the television receiver, the locally-stored location being stored by the television receiver;determine that the location region of the television receiver does not match the approved locally-stored location of the television receiver to within a threshold distance; andmodify functionality of the television receiver to output television channels in response to determining that the location region of the television receiver does not match the approved locally-stored location of the television receiver to within the threshold distance.
