PAL. 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.
NTSC. NTSC (from National Television System Committee) is the first American standard for analog television, published and adopted in 1941. [1] In 1961, it was assigned the designation System M. It is also known as EIA standard 170. [2] In 1953, a second NTSC standard was adopted, [3] which allowed for color television broadcast compatible with ...
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 ...
Most Digital8 units offer an LP mode, which increases the recording time on an NTSC P6-120 tape to 90 minutes. For PAL, the Digital8 recorder runs 1½ times faster; thus, a 90-minute PAL Hi8 tape yields 60 minutes of Digital8 video. PAL LP mode returns the tape speed to the Hi8 SP speed, so a Hi8 90-minute tape yields 90 minutes of Digital8 video.
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 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.
Television standards conversion. Television standards conversion is the process of changing a television transmission or recording from one video system to another. Converting video between different numbers of lines, frame rates, and color models in video pictures is a complex technical problem. However, the international exchange of ...
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.
