Abstract: A new single-channel, NTSC-compatible, wide-aspect extended-definition television (EDTV) system is proposed. It is an intermediate system, between the side-panel and letterbox systems. Unlike previously proposed intermediate systems, it widens the aspect ratio to 16:9 without using the horizontal blanking period. Moreover, it achieves 420 active lines using a bandwidth compression technique for side-panel signals. Conventional NTSC receivers display a center-panel portion of the widescreen image using 420 active lines, and side-panel signals are multiplexed into the remaining top and bottom areas of the image. High-frequency components are also transmitted, not only for the center-panel area but also for the side-panel area. This produces a high-quality, boundless widescreen image with more than 400 TV lines of horizontal and vertical resolution.
