Abstract：This paper presents an algorithm for coding color video signal using 3D-wavelet transformation. When the 3 color channels of RGB of the video signal are converted to color channels of YCbCr, and" the frame order t of the signal is replaced by order z, this signal can be considered as 3 blocks in a 3D-space. Each block presents a color channel. After splitting each block into smaller sub-blocks, imitate the method of 2D-wavelet transformation for image, the sub-blocks can be transformed with 3D-wavelet. Most of energy of each color channel is in
the transformed low-frequency bands. These bands affect the visual quality of the video signal
most. After quantizing different bands with different precision and entropy coding each band, the intra- and inter-frame redundancy of the color video signal can be eliminated and the data
can be compressed. Our simulation experiments show that this algorithm can obtain very good results.
