摘要

高清视频需要传输和接收的数据量巨大,难以发送和存储。本文提出了一种基于二值运动矢量技术的高清视频压缩技术。其中,为每个当前块搜索最佳匹配块的过程发生。所提出的技术保持高清质量,峰值信噪比至少为62 dB,灰度压缩比为26%。该技术在Xilinx Vertex 2 2V250fg456 FPGA上实现。硬件最高运行速度为63.8 MHz。FPGA利用率占总CLB片的12.37%,占总锁存器的8.61%。

Design and Implementation of a Video Compression Technique for High Definition Videos Implemented on a FPGA
High definition videos contain huge data to be transmitted and received, which is difficult to be sent and stored. In this paper a compression technique based on binary motion vector technique is used to compress HD videos. In which the process of searching for the best matching block for each current block occurs. The proposed technique keeps HD quality with at least Peak Signal to Noise Ratio 62 dB and along with 26% compression ratio on gray scale. The proposed technique is implemented on a Xilinx Vertex 2 2V250fg456 FPGA. The maximum operating speed of the hardware is 63.8 MHz. The FPGA utilization is 12.37% of total CLB slices and 8.61% of total latches.
