Bundling frames to save energy while streaming video from LTE mobile device

Published: 04 October 2013 Publication History

Abstract

It is becoming feasible to stream user generated video directly to the Internet, which enables a new class of exciting applications and services. However, energy consumption of smartphones that transmit the content over mobile network is a limiting factor. We study the potential of frame bundling to save energy while streaming video through a LTE uplink. Our simulation results show that if real-time streaming is not strictly necessary, bundling video frames for a few seconds before transmitting them is an effective mechanism to save energy. We analyze the energy savings achievable for different video bit rates with varying network conditions, namely round-trip time (RTT), packet loss, UE mobility, and background traffic. The results confirm that bundling remains effective also in non-ideal network conditions.
