Patent ID: 8261110

Claim:
A data processing apparatus for processing data to be transmitted to a data reproducing apparatus which reproduces received data stored in a received data storage unit, comprising: a signal processing unit for reading out and processing data stored in data storage unit; a wireless communication unit for wirelessly transmitting the data processed in said signal processing unit to said data reproducing apparatus; a signal processing control unit for controlling said signal processing unit so that said signal processing unit is able to operate intermittently by processing data within a time period less than a time period required for reproducing data at said data reproducing apparatus; a clock/power control unit for controlling a supply of at least one of clock signals and power supplies to said signal processing unit and said signal processing control unit so that the power consumption of said signal processing unit and said signal processing control unit is decreased by controlling the supply of at least one of the clock signals and the power supplies to at least one part of said signal processing unit and said signal processing control unit during a non-operating time period of said intermittent operation; and a start-up control unit for controlling a start-up process to request a release of controlling the supply of at least one of the clock signals and the power supplies to at least one part of said signal processing unit and said signal processing control unit to said clock/power control unit, and to request transferring to an operating time period of said intermittent operation to said signal processing control unit based on an amount of data stored in said received data storage unit.
