Abstract :
A fully NTSC-compatible two-channel wide-aspect-ratio high-definition television (HDTV) system with equal vertical and horizontal resolutions is described. The wideband Y, I, 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 proposed system produces minimal crossluminance and crosschrominance, and provides equal edge and center resolutions
