The NTSC 4.43 system, while not a broadcast format, appears most often as a playback function of PAL cassette format VCRs, beginning with the Sony 3/4" U-Matic format and then following onto Betamax and VHS format machines, commonly advertised as "NTSC playback on PAL TV". Multi-standard video monitors were already in use in Europe to ...
Some DVD players (usually lesser known brands) include an internal transcoder and the signal can be output in NTSC-M, with some video quality loss due to the standard conversion from a 625/50 PAL DVD to the NTSC-M 525/60 output format. A few DVD players sold in Argentina, Paraguay and Uruguay also allow a signal output of NTSC-M, PAL, or PAL-N.
NTSC discs may be output from a PAL DVD player in three different ways: using a non-chroma encoded format such as RGB SCART or YP B P R component video. using PAL 60 encoded composite video/S-Video—a "hybrid" system which uses NTSC's 525/60 line format along with PAL's chroma subcarrier; using NTSC encoded composite video/S-Video.
When transferred to NTSC television, the rate is effectively slowed to 23.976 FPS (24×1000÷1001 to be exact), and when transferred to PAL or SECAM it is sped up to 25 FPS. 35 mm movie cameras use a standard exposure rate of 24 FPS, though many cameras offer rates of 23.976 FPS for NTSC television and 25 FPS for PAL/SECAM.
Standard recording time is up to 90 minutes for PAL and 120 minutes for NTSC. These times are doubled for Long Play (LP) recording mode. (The cassette holds the same length tape; tape consumption is different between PAL and NTSC recorders.) Longer tapes were available, but were less common.
Analog television systems were standardized by the International Telecommunication Union (ITU) in 1961, [1] with each system designated by a letter (A-N) in combination with the color standard used (NTSC, PAL or SECAM) - for example PAL-B, NTSC-M, etc.). These analog systems for TV broadcasting dominated until the 2000s.
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. Aside from the line count being different, converting to a format that requires 60 fields every second from a format that has only 50 fields poses difficulty. Every second, an additional 10 ...
This preserves the pitch and sample rate of the audio, and the higher resolution of PAL video compared to NTSC, at the expense of more stuttery motion. [8] [9] Yet another method is frame blending, which preserves smooth motion but leaves ghosting artifacts. This method has been criticized by some as looking amateurish. [10] [11]
