Single-board wavelet video compression/decompression unit

Abstract

The system described is based on the wavelet video compression/decompression method, implemented on a single board and tailored for real-time work. Different bit-rates are supported in the full-duplex mode and in the range from 8-50 Mbit/s. The specific solution of the internal DMA transfer between the compressor/decompressor and the transmission FIFO buffers is described. Some considerations on the constant bit-rate implementation are given. An example for a live video transmission on an SDH loop is shown.
