NTSC color is usually associated with the System M; this combination is sometimes called NTSC II. [7] [8] The only other broadcast television system to use NTSC color was the System J. Brazil used System M with PAL color. Vietnam, Cambodia and Laos used System M with SECAM color - Vietnam later started using PAL in the early 1990s.
DV Audio/Video data can be stored as raw DV data stream file (data is written to a file as the data is received over FireWire, file extensions are .dv and .dif) or the DV data can be packed into container files (ex: Microsoft AVI, Apple MOV). The DV meta-information is preserved in both file types being Sub-timecode and Start/Stop date times ...
For DV-NTSC only 480 lines are used. The digitally transmitted horizontal resolution is usually 720 samples (which includes 16 samples for the horizontal sync and horizontal blanking) or 704 visible pixels with an aspect ratio of 4:3 (with vertically rectangular pixels) and therefore a display resolution of 640 × 480 ( VGA ); that is standard ...
This process can be reversed to retrieve the original 24 frame per second content. On NTSC DVDs, 24 frame per second content is stored as 60 interlaced frames per second using a process called 3:2 pulldown, which if done properly can also be reversed. ^ f As of July 2008, about 66.7% of Blu-ray discs are region free and 33.3% use region codes.

Those in NTSC countries, such as the United States, generally require both a region-free, multi-standard player and a multi-standard television to view PAL discs, or a converter box, whereas those in PAL countries generally require only a region-free player to view NTSC discs (with the possible exception of Japanese discs in most European ...
Introduced in 1999, Digital8 is a form of the industry standard DV codec, recorded on Hi8 media. In engineering terms, Digital8 and MiniDV are indistinguishable at the logical format level. To store the digitally encoded audio/video on a standard NTSC Video8 cassette, the tape must be run at double the Hi8 speed.
Perhaps the most technically challenging conversion to make is the PAL and SÉCAM to NTSC conversion. PAL and SÉCAM use 625 lines at 50 fields/s or 25 frames/s; NTSC uses 525 lines at 59.94 fields/s (60000/1001) or 30 frames/s; The NTSC standard is temporally and spatially incompatible with both PAL and SÉCAM.
So typical DV video is correctly listed as 480i/30. The long hand for 24p is 480p/24. Often the resolution is dropped and the i/p designation moved after the frame rate for shorthand. 24p cameras do not, as NTSC video cameras do, shoot 30 interlaced frames per second (60 fields); they shoot 24 full progressive frames per second.
