In this paper, an implementation of the video compression standard using SPIHT based on codec design is implemented. Here distributed arithmetic technique is used for pipelined bit-sequential operation as a multiply-accumulate operation. Discrete Wavelets decompose at one level of approximation and gives detailed information at the next level. These subsequent levels can add more details to the information content. For the encoder, dependences that prohibit parallel execution are resolved and a

A major objective of our proposed compression algorithm is to select the information which give up the largest possible resolution reduction is to be transmitted first. To reduce design complexity, Distributed arithmetic based 2D Discrete wavelet SPIHT compressor is proposed in this paper. This hybrid architecture can achieve more frames transmission compared to bit plane techniques.
