Abstract: The present paper presents a code and decode system based on the digital code of wavelet transform theory in order to implement multiresolution data flow encode and enha nce the interpolation of a system. This system is based on wavelet transform technique with digital signal processi ng method. An embedded zerotree encoder is designed on the basis of wavelet transform theory applied to the encode of video images a nd a video collection-play system is established that implements the data collection-play and is suitable to the play meeting the needs of proposed frequency and band width.

Key words: wavelet transform, multi-resolution-analysis, embedd ed zerotree wavelet encoder
