This paper addresses energy efficient packet scheduling for the transmission of multiple video streams over a wireless LAN. By exploiting the temporal scalability present in the prediction dependencies among video frames, a centralized cross-layer optimization solution is proposed, which is built on the HCF Controlled Channel Access (HCCA) of the IEEE 802. lie standard. Our performance study shows...
In wireless video streaming, it is desirable to minimize the energy consumption of mobile devices while achieving target video quality. For this purpose, it is essential to model (i.e., estimate) the energy cost of the streaming system, including both video encoder and wireless transmission energy, under different system settings. In this paper, an energy consumption model is proposed for a MPEG-4...
We consider the problem of packet scheduling for the transmission of multiple video streams over a wireless local area network (WLAN). A cross-layer optimization framework is proposed to minimize the wireless transceiver energy consumption while reaching the user required visual quality. The framework relies on the IEEE 802.11 standard and on a wavelet-based scalable video coding scheme. It extends...
We consider the problem of packet scheduling for the transmission of multiple video streams over a wireless local area network (WLAN). A cross-layer optimization framework is proposed to minimize the wireless transceiver energy consumption while meeting the user required visual quality constraints. The framework relies on the IEEE 802.11 standard and on the embedded bitstream structure of the scalable...
This paper focuses on the implementation challenges of recent developments in video compression standards. The collaborative effort, which goes under the name of joint video team (JVT), has recently completed the standardization of the new H.264/MPEG-4 advanced video coding (AVC) standard. The scalable video coding (SVC), will be standardized as an amendment to MPEG-4 Part 10 AVC/ITU-T 1-1.264. The...
