NTSC/PAL Playback-DVD Players

It is the ability of the DVD to play CDs recorded in Pal and NTSC broadcasting systems. There are several colour broadcasting systems such as PAL, NTSC, etc. DVDs are usually compatible to all of these. When a PAL based recording is played, the system transmits only PAL signals. Similarly, a NTSC video signal is transmitted from NTSC-based software.
