There are only three television standards in the world: PAL, NTSC, and SECAM. Each has their own attributes and they are not compatible with each other. DVD players as well as VHS players, are pre-made to read-only the TV standard they were created for. This is usually determined by the country the player was purchased in. Some of our equipment can playback other formats for example a VHS video recorder may be designed to record and playback PAL, however it may also be able to playback NTSC footage. We can also use hardware converters to change between the different systems if required. Here’s a brief explanation of the three different television standards and the countries that support them:
