摘要

该系统基于小波视频压缩/解压缩方法，在单板上实现，适合实时工作。全双工模式支持不同的比特率，范围为8 ~ 50mbit /s。描述了压缩机/减压器与传输FIFO缓冲器之间的内部DMA传输的具体解决方案。给出了恒比特率实现的一些考虑。给出了在SDH环路上进行实时视频传输的一个示例。

Single-board wavelet video compression/decompression unit

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.
