Abstract

A hierarchical wavelet transform coding structure which satisfies the requirements of high definition video cassette recorder (HD-VCR) for studio application in wireless environments is proposed. All of the coefficients in a transformed image are adaptively quantized and hierarchically converted into a single stream of binary symbols using the monotone decreasing property. The resulting bit stream goes through an adaptive arithmetic coder, and two-level control of bit rate is performed so as to maintain a constant target bit rate. The proposed algorithm can be efficiently implemented with much reduced computing time for the real world application. It is verified by simulation that for some test sequence of images at least 4 dB of PSNR improvement can be achieved compared with other DCT-based scheme at a constant target bit rate, avoiding the blocking effect which would be impossible otherwise.
