An Industry-Strength DVR System using an Efficient Compression Algorithm

효율적인 압축 알고리즘을 이용한 실용화 수준의 DVR 시스템

  • Published : 2004.06.01


We describe a practical implementation of DVR (Digital Video Recording) system. And we propose a new image compression algorithm, that input video signal is divided into two parts, a moving target and a non-moving background part to achieve efficient compression of image sequences. This algorithm reorganizes a target area and a back-ground area by use of Macro Block(MB) unit on encoding scheme. The proposed algorithm allows high quality image reconstruction at low bit rates.
