DefinitionPower-rate distortion analysis is important for wireless video communication applications in energy management, resource allocation, and QoS provisioning, especially over wireless video sensor networks.To design an energy-scalable standard video encoder, we take three major steps: 1.We group the encoding operations into several modules, such as motion prediction, pre-coding (transform and quantization), and entropy coding, and then introduce a set of control parameters Γ = [γ1, γ2,….γL] to control the power consumption of each module. The encoding power consumption, denoted by P, is then a function of Γ, denoted by P(γ1, γ2,….γL). The expression of this function also depends on the power consumption model of the specific micro-processor [1,2]. 2.We analyze the rate-distortion behavior of each control parameter, and integrate these models into a comprehensive parametric rate-distortion model for the video encoder, denoted by D(R; γ1, γ ...
