Energy/QoS provisioning is challenging for video applications over lossy wireless network with power-constrained mobile handheld devices. In this paper, the authors exploit the inherent error-tolerance of video data to generate a range of acceptable operating points by controlling the amount of errors in the system. In particular, they propose an error-aware video encoding technique - EAVE - that intentionally injects errors while ensuring acceptable QoS. The expanded tradeoff space generated by EAVE allows system designers to comparatively evaluate different operating points with varying QoS and energy consumption by aggressively exploiting error-resilience attributes, and can potentially result in significant energy savings.
