Abstract
The capability of progressive transmission according to resolution and rate scalability is considered essential for emerging video applications to multimedia. This paper presents the 3D wavelet based video subband coder using quad-tree algorithm. The proposed video coding system decomposes the input sequence into temporal and spatial subbands and relatively allocates the higher bit rate to the low frequency image of the 3D wavelet sequences. Moreover, the proposed system limits error propagation within a certain group of frames (GOF) and improves the PSNR performance of the reconstructed image. In addition, the proposed system progressively transmits the embedded bit stream according to the resolution and rate scalability.
