NTSC 

In addition to region codes, there are also differences in discs for NTSC and PAL TV systems

The MPEG video on DVD is stored in digital format, but it's formatted for one of two mutually incompatible television systems: NTSC or PAL/SECAM. Therefore, there are two kinds of DVDs: NTSC DVDs and PAL DVDs. Some players only play NTSC discs, others play PAL and NTSC discs.

All DVD players sold in PAL countries play both kinds of discs. These multi-standard players convert NTSC to PAL .

Most NTSC players can't play PAL discs. A very small number of NTSC players can convert PAL to NTSC.

So, if you have a NTSC only DVD player you will NOT be able to play a PAL disc unless you use a standards converter box.

DVD discs are still either PAL or NTSC standard. Also, similar to multisystem VCRs, DVD players will not convert video standards. When you're playing an NTSC-standard DVD, it will output an NTSC signal. When you're playing a PAL-standard DVD, it will output a PAL signal.

There are two ways to watch both PAL and NTSC DVDs. You can either view your DVDs on a multisystem TV, or purchase a Tenlab video converter to convert your DVD player's output signal. A multisystem TV has the ability to receive and display both PAL and NTSC video signals. A Tenlab video converter would receive a video signal and convert the signal into the desired video standard. So if you wanted to watch a PAL DVD disc and you had only an NTSC television, the Tenlab converter could convert the signal from PAL to NTSC, which would then be viewable on your television.( for USA costumers )
