Patent ID: 7983650

Claim:
A wireless communication device comprising: a first battery that supplies power to the wireless communication device; a power control module that detects a remaining power amount in the first battery; a first power consumption information module that determines first power consumption information including a plurality of data pieces each indicating power consumption in the wireless communication device for processing a streaming data signal encoded in each of a plurality of encoding formats; a wireless communication unit that wirelessly receives second power consumption information from a second device that is powered by a second battery, the second power consumption information including a plurality of data pieces each indicating power consumption in the second device for processing the streaming data signal encoded in each of the plurality of encoding formats, the wireless communication unit further receiving a remaining power amount of the second battery; an encoding format selection module that selects one of the encoding formats for a data signal to be transmitted, based on the first power consumption information, the second power consumption information, remaining power amount of the first battery, and the remaining power amount of the second battery; and an encoding controller that encodes the data signal to be transmitted in the encoding format selected by the encoding format selection module to generate an encoded data signal as a streaming data and outputs the encoded data signal to the wireless communication unit, wherein the wireless communication unit wirelessly transmits the encoded data signal as the streaming data to the second device.
