摘要

描述了一种完全兼容ntsc的双通道宽宽比HDTV(高清晰度电视)系统，具有相同的垂直和水平分辨率。宽带、Y、I和Q分量在频谱上分为低频和高频频段。然而，只有低频分量在空间上被分割成中心和边缘段。对低频边缘信号进行NTSC编码和解码，使用现有的硬件来兼容中心信号。该系统使用增强垂直滤波器，产生最小的交叉亮度和交叉色度，同时提供相等的边缘和中心分辨率。

A fully compatible HDTV system with equi-resolution

A fully NTSC-compatible, two-channel, wide aspect-ratio HDTV (high-definition television) system with equal vertical and horizontal resolutions is described. The wideband, Y, I and Q components are spectrally split into low-frequency and high-frequency bands. However, only the low-frequency components are spatially split into center and edge segments. The low-frequency edge signals are NTSC encoded and decoded using the existing hardware for the compatible center signals. The system uses augmented vertical filters and produces minimal cross-luminance and cross-chrominance, while providing equal edge and center resolutions.<>
