Abstract
An embodiment of the present invention provides an apparatus, comprising a digital television (DTV) receiver including at least a one-bit-flag such that when the flag is “on”, the DTV receiver is not allowed to start an initial acquisition process, and at least one additional receiver sharing part of a receive chain of the DTV receiver and wherein the additional receiver is capable of turning the one-bit-flag “on”. The flag may be set through communication between the drivers of the DTV receiver and the at least one additional receiver.
Claims19
An apparatus, comprising:
- a digital television (DTV) receiver including at least a one-bit-flag such that when said flag is “on”, the DTV receiver is not allowed to start an initial acquisition process;
- and
- at least one additional receiver sharing part of a receive chain of said DTV receiver and wherein said additional receiver is capable of turning said one-bit-flag “on”.
A method, comprising:
- including at least one-bit-flag in a digital television (DTV) receiver such that when said flag is “on”, the DTV receiver is not allowed to start an initial acquisition process;
- and
- sharing part of a receive chain of said DTV receiver by at least one additional receiver and wherein said additional receiver is capable of turning said one-bit-flag “on”.
A machine-accessible medium that provides instructions, which when accessed, cause a machine to perform operations comprising:
- including at least one-bit-flag in a digital television (DTV) receiver such that when said flag is “on”, the DTV receiver is not allowed to start an initial acquisition process;
- and
- sharing part of a receive chain of said DTV receiver by at least one additional receiver and wherein said additional receiver is capable of turning said one-bit-flag “on”.
A system, comprising:
- a GPS receiver;
- a digital television receiver (DTV) operable on the same receive chain as said GPS receiver and including at least a one-bit-flag at the DTV MAC layer such that when this flag is “on”, the DTV receiver is not allowed to start an initial acquisition process thereby allowing said DTV and GPS receiver to coexist;
- and
- wherein said DTV receiver includes a DTV driver, fed by the GPS driver and is responsible for turning this flag to “on” mode when GPS reception is performed and to “off” when said GPS reception is powered down.
