A method for managing information signal distribution in a communication system (100) includes transmitting a signal containing information configured according to a first media format from a first communication device (104) to a second communication device (110). At least one of the two devices (104, 110) monitors at least one operating characteristic of a depletable power supply (318) sourcing electrical energy for the second device (110). When a level of the monitored operating characteristic falls below a predetermined threshold, the first communication device (104) outputs the information to the second communication device (110) according to a second media format that requires less power consumption to process than does the first media format. Alternatively, under such circumstances, the first communication device (104) may output the information to a media output device other than the second communication device (110). |
