Receiving apparatus and receiving method of reduced power consumption for receiving a broadcast transmission
First Claim
Patent Images
1. A receiving apparatus for receiving a broadcast transmission comprising:
- a signal-processing unit for carrying out processing the received signal at a plurality of stages in a predetermined order;
a judgment device for determining whether or not it is normal to process the signal in at least one of the stages; and
a control device for controlling power supply to make the signal-processing unit carry out the received signal processing, on each stage, only when the judgment device determined that an immediately-prior stage is normally carried out.

Abstract
A receiving apparatus that is capable of effectively reducing power consumption in the receiving state. The receiving apparatus is provided with: an RF tuner, digital-demodulation unit, error-correction unit, demultiplexing unit and decoding unit. A control unit determines whether or not processing of the signal by the RF tuner, digital-demodulation unit, error-correction unit, demultiplexing unit or decoding unit is possible, and when it determines that signal processing is not possible, it controls switches such that operation in the corresponding part and after the corresponding part stops.

15. A receiving method of receiving a broadcast transmission comprising:
-
a signal-processing process of processing the received signal at a plurality of stages in a predetermined order; a judgment step of determining whether or not it is normal to process the signal in at least one of the stages; and a control step of controlling power supply necessary for activating each of the stages, only when the judgment step determined that an immediately-prior stage is normally carried out. - View Dependent Claims (16)
