|The NTSC format (National Television Standards Committee) is the standard-definition television format for the United States, Canada, Japan, Mexico and other countries. The NTSC video format definition is 30 (29.97) interlaced frames per second, 525 resolution lines per video frame.
Home video products for use in the United States and Canada must be in the NTSC format to properly display both picture and sound. Home video products from Europe are manufactured in the PAL television format and from France and Russia in the SECAM television formats and they will not properly image on NTSC television systems, as American media producers have pressured disc player manufacturers to restrict playback access to NTSC discs.
As with other standard television formats, NTSC is being phased out for the generally universal DVB high-definition format.
