ELI5: Explain Like I'm 5

NTSC-J

NTSC-J stands for National Television System Committee Japan. It is a type of video format that is used in Japan. Video formats tell us how a video should be displayed on a TV. NTSC-J is not the same as other video formats like PAL or HD, and it is only used in Japan. This is because only TVs in Japan are built to accept the NTSC-J format. That means if you try to play a video that uses NTSC-J in a different country, you won't be able to watch it because the TV won't understand it.
