以下是AVS论坛上一位特级会员关于此问题的解释,仅供参考:
How can 1024x768 be HD, you ask. Many dozens of people have asked that over and over here in the forum. The answer is, the Consumer Electronics Association has decided that any display with at least 720 lines can be called an HDTV and have the logo. There is some basis in fact for this because the human eye is more sensitive to vertical resolution than to horizontal resolution. This has been taken advantage of for years in NTSC because the horizontal resolution of NTSC is really poor. It is also taken advantage of in so-called HD-lite where the video is resampled to 1440x1080 on things like satellite, or maybe even shot with a 1440x1080 camera instead of the 1920x1080 camera you thought the network was using, and you probably didn't even notice. |
