摘要
分析研究了基于MPEG-2标准的高清晰度数字电视信源编码技术,阐述了小波分析中多分辨分析的基本思想和理论,并将基于多分辨思想的Mallat算法较好地应用于HDTV的图像压缩编码系统中。
This paper makes a deep research on the source coding technique in High Definition TV system based on MPEG2 Standard, describing the main idea and fundamental theory about multiresolution analysis(MRA)in wavelet transform. Also, the Mallat algorithm based on MRA theory is well applied to HDTV image compression coding system.
