PAL:- Is a format widely used in Europe, Australia, Asia and Africa. PAL stands for Phase Alternation Lines and has various sub-systems for VHF and UHF bands for each country. SECAM:- Is mainly used in Eastern Europe and France (SECAM-L) SECAM stands for System Electronique Couleur Avec Memoire was founded by Frenchs. NTSC stands for the National Television Systems Committee who developed the system and public broadcasting of NTSC began in the United States in 1954.

From a hardware point of view there is. A consumer CD-i player is localized for a specific broadcast system. The output signal of the video connectors is according to this local system. You can tell which broadcast system is used by looking at the version indication after the normal type ID (refer to What does the /00, /20, etc. after the type-indication mean?).

NTSC (National Television Standards Committee) is a standard used in North America , Japan,Korea, the Philippines and parts of South America. It has the ability to display up to 525 lines of resolution. PAL (Phase Alternating Line), a standard used almost everywhere else in the world, has the ability to display 625 lines of resolution.

NTSC (National Television Standards Committee), PAL (Phase Alternating Lines) and SECAM (SEquentiel Couleur Avec Memoire) are different worldwide, generally incompatible television standards. Some short, not completely accurate information follows. what where freq/frames/scan lines ---- ----- ---------------------- NTSC US/Japan 60hz/30/525 PAL Europe 50hz/25/625 SECAM France & many others 50hz/25/625 For detailed and accurate (but muddled) information, see the Worldwide TV standards page.

NTSC (National Television Standards Committee) is a standard used in North America and Japan. It has the ability to display up to 525 lines of resolution. PAL (Phase Alternating Line), a standard used almost everywhere else in the world, has the ability to display 625 lines of resolution. SECAM (Sequential Color Memory) is used sparingly around the world and can be found in France, parts of Greece, Eastern Europe, Russia, Africa and a few other parts of the world.

DVD-V has the same NTSC vs. PAL problem as videotape and laserdisc. The MPEG video on DVD is stored in digital format, but it's formatted for one of two mutually incompatible television systems: 525/60 (NTSC) or 625/50 (PAL/SECAM). There are three differences between discs intended for playback on different systems: picture size and pixel aspect ratio (720x480 vs. 720x576), display frame rate (29.97 vs 25), and surround audio (Dolby Digital vs. MPEG). (See 3.4 and 3.6 for details.

There is no such thing as a blank NTSC, SECAM or PAL tape. NTSC, SECAM and PAL refer to different standards used to record video onto a blank tape. Therefore, when purchasing blank tapes you do not need to be concerned about whether the tape is NTSC, SECAM or PAL.

Different countries use different methods of recording and playback. Please go to Video Standards for a complete explanation of this.

Not really. DVD supports two television systems: 525/60 (NTSC) and 625/50 (PAL). There are three differences between discs intended for different markets: picture size (720x480 vs. 720x576), frame rate (29.97 vs 25), and surround audio (Dolby Digital vs. MPEG-2). (See 3.3 and 3.5 for details.) However, a producer can choose to include additional video and audio --at the expense of playing time-- so that all formats are covered.

There are two basic formats of television signal. In the UK and Europe (and Japan) the standard is called 'PAL', yet in America the standard format is 'NTSC'. DVD discs can be encoded in either of these two formats, and this should not be confused with Region Coding as this is something completely different. In almost all cases, NTSC discs can be played within the UK and Europe without any problems.

These are two different TV picture standards. Region 2 (Europe) uses the PAL standard whereas region 1 (USA and Canada) uses the NTSC standard. These standards are incompatible with one another and to be able to view a region 1 DVD on a UK TV, you'll need to have an NTSC compatible or multi-standard TV.
