In this paper, the authors profile a particular tradeoff between power budget and video quality that emerges in the transmission of multimedia packets over a wireless channel. These packets are due to arrive to a receiver at a particular time, so they consider a finite horizon problem over which multimedia data are transmitted. Due to the lossy nature of the wireless channel, however, not every packet can be successfully sent across the channel. Hence, each packet that is lost leads to distortion in the video that is experienced by the receiver. They suppose that there are M packets that must arrive at the receiver within N time steps, but that power limitations constrain the number of transmissions.
