NTSC-J or "System J" is the informal designation for the analogue television standard used in Japan. The system is based on the US NTSC ( NTSC-M ) standard with minor differences. [ 1 ] While NTSC-M is an official CCIR [ 2 ] [ 3 ] [ 4 ] and FCC [ 5 ] [ 6 ] [ 7 ] standard, NTSC-J or "System J" are a colloquial indicators.
The channel encoding on NTSC-J differs slightly from NTSC-M. In particular, the Japanese VHF band runs from channels 1–12 (located on frequencies directly above the 76–90 MHz Japanese FM radio band) while the North American VHF TV band uses channels 2–13 (54–72 MHz, 76–88 MHz and 174–216 MHz) with 88–108 MHz allocated to FM radio ...
Analog television system by nation Analog color television encoding standards by nation. Every analog television system bar one began as a black-and-white system. Each country, faced with local political, technical, and economic issues, adopted a color television standard which was grafted onto an existing monochrome system such as CCIR System M, using gaps in the video spectrum (explained ...
Instead, virtual channels, sent as part of the metadata along with the program(s), allow channel numbers to be remapped from their physical RF channel to any other number 1 to 99, so that ATSC stations can either be associated with the related NTSC channel numbers, or all stations on a network can use the same number.
PAL's color encoding is similar to the NTSC systems. SECAM, though, uses a different modulation approach than PAL or NTSC. PAL had a late evolution called PALplus , allowing widescreen broadcasts while remaining fully compatible with existing PAL equipment.
Multichannel Television Sound (MTS) is the method of encoding three additional audio channels into analog 4.5 MHz audio carriers on System M and System N.The system was developed by an industry group known as the Broadcast Television Systems Committee (BTSC), a parallel to color television's National Television System Committee, which developed the NTSC television standard.
Both the GameCube and Wii are region-locked, and the Wii Shop Channel is also region-locked as well. On the Wii, channels from other regions will refuse to load with the message "This channel can't be used." The coded regions are: NTSC-U (The Americas and Asia) PAL (Europe and Oceania) NTSC-J (Japan) NTSC-K (South Korea)
EIA-608 defines four channels of caption information, so that a program could, for example, have captions in four different languages. There are two channels, called 1 and 2 by the standard, in each of the two fields of a frame. The channels are often presented to users numbered simply as CC1-2 for the odd field and CC3-4 for the even field.
