NTSC-J
From Wikipedia, the free encyclopedia
NTSC-J is an analog television system and video display standard for the region of Japan.
[edit] Technical definition
It is based on 'regular' NTSC, but is slightly different. The black level and blanking level of the NTSC-J signal are identical (at 0 IRE), as they are in PAL, another video standard, while in American NTSC, black level is slightly higher (7.5 IRE) than blanking level.
- Since the difference is quite small, a slight turn of the brightness knob is all that is required to enjoy the "other" variant of NTSC on any set as it is supposed to be; most watchers might not even notice the difference in the first place.
- NTSC VHS videotape uses 7.5 IRE units
- PAL S-VHS uses 0.0 IRE units
[edit] Marketing definition
The term NTSC-J is also used to distinguish regions in console video games, which use televisions. NTSC-J is used as the name of the video gaming region in Japan. Games designated as part of this region will not run on hardware designated as part of the NTSC-US or PAL mostly due to the regional differences of the standards, but there is usually a kind of regional lockout built into the video game systems in question.
