DELIVERING MEDIA DATA TO PORTABLE COMPUTING DEVICES

摘要

Power consumption in a portable computing device's receive-transmit subsystem is reduced when this subsystem receives streaming media data. The portable computing device receives a first portion of the media data via a first communication channel and a second portion of the media data via a second channel. The portable computing device may obtain the first portion well in advance of receiving the second portion and may use a wireless connection to receive the second portion. The portable computing device may terminate the wireless connection once the second portion has been received, thus reducing overall power consumption in wireless device. A client application on the portable computing device reassembles the media file form the first and second portions.
