Low Bit Rate Video Signal Processing Using Dynamic Profiling

Abstract

In this paper the three algorithm are used for low bit rate colour video signal processing, namely simple dynamic profiling (simple DP), minimum dynamic profiling (minimum DP), mean dynamic profiling (mean DP). This technique is used in conjunction with frame reduction scheme to lower the bit rate without much affecting the colour video signal. Many of the techniques available for low bit rate video applications will either require lot of hardware resources or take advantage of the powerful computer platform that is used for their software implementation. The algorithms used are devised targeting hardware implementation for systems with limited hardware resources. The algorithms can be used for multiple colour frames for any type of video signals. When the results are compared to coarse quantization technique, the new techniques not only achieve better compression ratio and better PSNR results for colour video
