Abstract

Most mobile video applications are often operated on battery energy supply devices. The higher resolutions and complex functionality of video applications need high resource requirements. Thus, power efficient design plays an important role in computation intensive applications especially for video encoding systems. This paper proposed a power-scalable video encoding scheme (PSVE) for energy limited systems. The PSVE establishes game theoretical analysis and models the power consumption problem as a game problem. PSVE can make video encoder work under variable energy resource constraint while keep better performance. It uses game theory to solve the tradeoff between encoding effect and power consumption. Experimental results demonstrate the efficiency of the proposed approach.
