Abstract

To overcome the disadvantages of output stream volatility due to the ignorance of the complexity of different frame types by IPP development platform for H.264 in TETRA, a layered rate control algorithm is proposed. According to the channel conditions and buffer state, the proposed algorithm allocates bits to Group of Picture (GOP), frame and MB, respectively. Then, the optimized RD model and allocated bits are used to determine quantization parameter ( ). Simulation results show the variance of the number of coding bits and coding time per frame decreases respectively by 61.3% and 57.4%, while the average PSNR increases 0.2dB.
