Abstract
Recently, an idea of source splitting [1] has been proposed, which reduces average bitrate for encoding run-level symbols of quantized DCT coefficients. This paper presents an efficient method which allows the source splitting idea to be practically applied to video coding systems. The proposed method consists of (i) an iterative pairwise splitting algorithm for fast finding optimal splitting indices; (ii) a memory allocation algorithm for determining the Huffman table sizes; (iii) and an exhasutive search algorithm for determining the number of Huffman tables to be used. Simulation results show that the bitrate reduction performance can be further improved by using the proposed improved method and that computational burden can be also considerably reduced with the proposed method.
