That is the country code. A jap DVD can only be played on a Jap DVD player. A US DVD can only be played on a US DVD player, etc.

Answer 2

NTSC - National Television System Committee

The first colour TV broadcast system was implemented in the United States in 1953. This was based on the NTSC - National Television System Committee standard. NTSC is used by many countries on the American continent as well as many Asian countries including Japan.
NTSC runs on 525 lines/frame.

SYSTEM NTSC M
Lines/Field 525/60
Horizantal Frequency 15.734 kHz
Vertical Frequency 60 Hz
Colour Subcarrier Frequency 3.579545 MHz
Video Bandwidth 4.2 MHz
Sound Carrier 4.5 MHz

PAL - Phase Alternating Line

The PAL - Phase Alternating Line standard was introduced in the early 1960's and implemented in most European countries except for France.
The PAL standard utilises a wider channel bandwidth than NTSC which allows for better picture quality.
PAL runs on 625 lines/frame.

SYSTEM PAL B,G,H
Line/Field 625/50
Horizontal Frequency 15.625 kHz
Vertical Frequency 50 Hz
Colour Sub Carrier Frequency 4.433618 MHz
Video Bandwidth 5.0 MHz
Sound Carrier 5.5 MHz

SYSTEM PAL I
Line/Field 625/50
Horizontal Frequency 15.625 kHz
Vertical Frequency 50 Hz
Colour Sub Carrier Frequency 4.433618 MHz
Video Bandwidth 5.5 MHz
Sound Carrier 6.0 MHz

SYSTEM PAL D
Line/Field 625/50
Horizontal Frequency 15.625 kHz
Vertical Frequency 50 Hz
Colour Sub Carrier Frequency 4.433618 MHz
Video Bandwidth 6.0 MHz
Sound Carrier 6.5 MHz

SYSTEM PAL N
Line/Field 625/50
Horizontal Frequency 15.625 kHz
Vertical Frequency 50 Hz
Colour Sub Carrier Frequency 3.582056 MHz
Video Bandwidth 4.2 MHz
Sound Carrier 4.5 MHz

SYSTEM PAL M
Line/Field 525/60
Horizontal Frequency 15.750 kHz
Vertical Frequency 60 Hz
Colour Sub Carrier Frequency 3.575611 MHz
Video Bandwidth 4.2 MHz
Sound Carrier 4.5 MHz

SECAM - Sequential Couleur Avec Memoire

The SECAM - Sequential Couleur Avec Memoire or Sequential Colour with Memory standard was introduced in the early 1960's and implemented in France. SECAM uses the same bandwidth as PAL but transmits the colour information sequentially.
SECAM runs on 625 lines/frame.

SYSTEM SECAM B,G,H
Line/Field 625/50
Horizontal Frequency 15.625 kHz
Vertical Frequency 50 Hz
Video Bandwidth 5.0 MHz
Sound Carrier 5.5 MHz


SYSTEM SECAM D,K,K1,L
Line/Field 625/50
Horizontal Frequency 15.625 kHz
Vertical Frequency 50 Hz
Video Bandwidth 6.0 MHz
Sound Carrier 6.5 MHz


I hope it helps.

Answer 3

Screen resolutions are different in some countries. Many European countries have PAL as the standard, while the U.S. has NTSC.

You can easily google search the two for more info or look on Wikipedia.

Answer 4

the main difference between these systems are the way the color wave is carried by the frequency signal as each system has its own way to carry the color signal and thats a way to hard to be explained here but u can for sure find it on the interent if u r interested and u have the background .

Answer 5

Basically the "language" in which it's written.

They are different "languages" for the hardware, like Arabic is to English is to Japanese.
