Digital Television Signal Processing and Display Technology

摘要

Sony is introducing a new DTV television set into the market in fall 1998. There are some advances in display technology that set it apart from other products which will be introduced into the market. The flat screen "FD Trinitron" is a 34V (36 inch) CRT in which the front surface is completely flat. The picture is therefore free from geometric distortions that all other CRT's exhibit. The DRC (Digital Reality Creator) circuit transforms analog NTSC signals into high definition TV video by not only doubling the horizontal lines, but by increasing the horizontal resolution as well. This gives the viewer an almost HDTV quality picture from standard NTSC video. The MID (Multi-Image Driver) displays up to 12 multiple images on the television screen. The images can be real-time scaled to different sizes on the screen.
