DATA COMMUNICATION DEVICE, DATA COMMUNICATION METHOD AND PROGRAM THEREOF
First Claim
1. A communication device, comprising:
- a communication unit including plural function operation units performing communication with an external device at plural prescribed communication speeds; and
a control unit allowing the communication unit to receive a given kind of content data from the external device, estimating an optimum prescribed communication speed in which the power consumption amount becomes smallest from the plural prescribed communication speeds based on a bit rate of the content data, selecting a given function operation unit from the plural function operation units based on the estimated optimum communication speed, allowing the selected function operation unit to receive the given kind of content data at the estimated prescribed communication speed and controlling power consumption to the function operation units other than the function operation unit selected from the plural function operation units to be less than a fixed value.

Abstract
A communication device includes a communication unit having plural function operation units performing communication with an external device at plural prescribed communication speeds, and a control unit allowing the communication unit to receive a given kind of content data from the external device, estimating an optimum prescribed communication speed in which the power consumption amount becomes smallest from the plural prescribed communication speeds based on a bit rate of the content data, selecting a given function operation unit from the plural function operation units based on the estimated optimum communication speed, allowing the selected function operation unit to receive the given kind of content data at the estimated prescribed communication speed and controlling power consumption to the function operation units other than the function operation unit selected from the plural function operation units to be less than a fixed value.
