Abstract :
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
