HDTV Bandwidth Compression Technique for the Japanese MUSE System

本文叙述了可在单一卫星通道内传送的日本HDTV传输体制MUSE的频带压缩技术。它利用人眼的视觉特性,采用多重亚奈取样方式,将信号基带降低到8.1MHz。

This paper presents a bandwidth compression technique in the Japanese MUSE system which can be transmitted over a single satellite channel. It makes use of multiple Sub-Nyquist Sampling encoding which adapts to human visual characteristics, thus can reduce the baseband of sig- nals to 8.1MHz.
