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. Aside from the line count being different, converting to a format that requires 60 fields every second from a format that has only 50 ...
When operating in this mode most of them do not output a true (625/50) PAL signal, but rather a hybrid consisting of the original NTSC line standard (525/60), with colour converted to PAL 4.43 MHz (instead of 3.58 as with NTSC and South American PAL variants and with the PAL-specific phase alternation of colour difference signal between the ...
PAL-M is the analogue colour TV system used in Brazil since early 1972, [1][2] making it the first South American country to broadcast in colour. It is unique among analogue TV systems in that it combines the 525-line 30 frames-per-second System M with the PAL colour encoding system (using very nearly the NTSC colour subcarrier frequency ...
576i is a standard-definition digital video mode, [1] originally used for digitizing 625 line analogue television in most countries of the world where the utility frequency for electric power distribution is 50 Hz. Because of its close association with the legacy colour encoding systems, it is often referred to as PAL, PAL/ SECAM or SECAM when ...
Typically, for 25 frame/s formats (European among other countries with 50 Hz mains supply), the content is PAL speedup, while a technique known as "3:2 pulldown" is used for 30 frame/s formats (North America among other countries with 60 Hz mains supply) to match the film frame rate to the video frame rate without speeding up the play back.
This subtle simplification caused NTSC sets to scan 240p/60 instead of 480i60, with similar results for PAL. While this actually improved picture quality for the kind of low-definition images that videogames of this era generated, such a signal modification could cause problems in a broadcast environment as the signal behaviour is outside the ...
Though the color standards are often used as synonyms for the underlying video standard - NTSC for 525i/60, PAL/SECAM for 625i/50 - there are several cases of inversions or other modifications; e.g. PAL color is used on otherwise "NTSC" (that is, 525i/60) broadcasts in Brazil, as well as vice versa elsewhere, along with cases of PAL bandwidth ...
These images are output as 60 (NTSC) or 50 (PAL) interlaced fields. The result is a progressive-scan content, which is compatible with traditional interlaced scanning systems. This is how Sony described the progressive recording mode in the operating guide for a 60 Hz ("NTSC") Sony DCR-HC96 camcorder: Note on the progressive recording mode
