Abstract

A data transmitting apparatus for processing data to be transmitted to a data receiving apparatus which reproduces received data stored in a received data storage unit, comprising: a signal processor for processing data; a transmitter for wirelessly transmitting the data processed in the signal processor to the data receiving apparatus; a signal processing controller for controlling the signal processor to operate intermittently; a clock/power controller for restricting a clock signal supply and/or power supply to the signal processing controller during a non-operating time period of the intermittent operation; and a wake-up controller for lifting the restriction put by the clock/power controller based on an amount of data stored in the received data storage unit.

Claims

1. A data transmitting apparatus for processing data to be transmitted to a data receiving apparatus which reproduces received data stored in a received data storage unit, comprising:

a signal processor for processing data;

a transmitter for wirelessly transmitting the data processed in said signal processor to said data receiving apparatus;

a signal processing controller for controlling said signal processor to operate intermittently;

a clock/power controller for restricting a clock signal supply and/or power supply to said signal processing controller during a non-operating time period of said intermittent operation; and

a wake-up controller for lifting the restriction put by said clock/power controller based on an amount of data stored in said received data storage unit.

2. A data transmitting method in a data transmitting apparatus of processing data to be transmitted to a data receiving apparatus which reproduces received data stored in a received data storage unit, comprising steps of:

a signal processing step of processing data;

a transmitting step of wirelessly transmitting the data processed at said signal processing step to said data receiving apparatus;

a signal processing controlling step of controlling said signal processing step to operate intermittently;

a clock/power controlling step of restricting a clock signal supply and/or power supply during a non-operating time period of said intermittent operation; and

a wake-up controlling step of lifting the restriction put at said clock/power controlling step based on an amount of data stored in said received data storage unit.
