Abstract

An apparatus such as a television signal processing apparatus 200 provides a means to control power dissipation by high speed signal processing circuitry associated with tuners 230, 250 while continuing to receive auxiliary data such as administrative data, guide data, or emergency alert notifications . According to an exemplary embodiment, the television signal processing apparatus 200 comprises a first tuner 230 for tuning a first signal when the television signal processing apparatus is in a first modem of operation and where power is removed from the first tuner 230 during a second mode of operation, a second tuner 250 for tuning a second signal when the television signal processing apparatus 200 is in a first mode of operation and a second mode of operation, wherein power is applied to the second tuner 250 for a portion of the time the television signal processing apparatus 200 is in the second mode of operation and the portion of the time the television signal processing apparatus 200 is in the second mode of operation is less than 100 percent of the time the television signal processing apparatus 200 is in the second mode of operation.
