One of the main challenges of video-coding is to provide the guaranteed quality under highly compressed video. In our study, a structured R-Q base rate-control framework is proposed for low-delay video coding, which contains thrcc processing stages: the control of encoding frame-rate, bit-allocation for frame-level and the decision of quantization parameters for macroblock-level. First, thc proposed framework decides the encoding frame-rate per group of pictures (COPS) for better motion continuity. In the second stage, target-bit per frame is effectively estimated with the frame texture and buffer fullness. Last, based on an adaptive R-Q model modified by the Kalman filter for each cluster of MBs (COBs), a suitable.quantization parameter of each MB can be confirmed. In comparison with the TMNXrc module, our new framework can achieve higher objective and perceptual quality with lower computational complexity'.
