Original Abstract

This paper is about video compression method based on the 3D DCT. Properties of this algorithm depend on the way how 3D DCT coefficients are grouped together into output bit stream. In the next text we briefly describe the main components of the encoder and decoder architecture including the definitions of mathematical operations of the Forward and Inverse Three Dimensional Discrete Cosine Transform. Secondly, two scan orders for 3D DCT coefficients are presented. Also the modified Huffman dictionary for 3D DCT coefficients is discussed. The experimental confirmation of proposed methods is realized as well.
