Analog television encoding systems by nation: NTSC (green), SECAM (orange), and PAL (blue) SECAM, also written SÉCAM (French pronunciation:, Séquentiel de couleur à mémoire, French for color sequential with memory), is an analog color television system that was used in France, Russia and some other countries or territories of Europe and Africa.
Analog television encoding systems by nation: NTSC (green), SECAM (orange), and PAL (blue) Phase Alternating Line (PAL) is a colour encoding system for analog television.It was one of three major analogue colour television standards, the others being NTSC and SECAM.
Because of its close association with the legacy colour encoding systems, it is often referred to as PAL, PAL/SECAM or SECAM when compared to its 60 Hz (typically, see PAL-M) NTSC-colour-encoded counterpart, 480i. The 576 identifies a vertical resolution of 576 lines, and the i identifies it as an interlaced resolution. [1]
25i, also known as 50i, is an interlaced format showing 25 interlaced frames per second, or 50 fields per second, and is the standard broadcast framerate for countries with a PAL and SECAM television history (most of the world). The interlaced format sacrifices some detail in vertical resolution in favor of a higher apparent framerate, and can ...
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.
PAL and SECAM televisions had less of a need for one. SECAM in particular was very robust, but PAL, while excellent in maintaining skin tones which viewers are particularly sensitive to, nevertheless would distort other colors in the face of phase errors. With phase errors, only "Deluxe PAL" receivers would get rid of "Hanover bars" distortion.
SECAM, PAL: Color broadcasting started on 26 February 1975. [83] Used SECAM from 1968 to 1996. PAL has been in use since 1997. Luxembourg * 1967/ 1972: Compagnie Luxembourgeoise de Télédiffusion: PAL, SECAM: The then only channel for audiences in Luxembourg, France and Belgium originally used the French/Belgian 819-line black and white ...
SECAM, a format associated with French-speaking Europe, while using the same resolution and refresh rate as PAL, is a distinct format which uses a very different system of color encoding. Some DVD players can only play discs identified as NTSC, PAL or SECAM, while others can play multiple standards. [9]
