480i is a shorthand name for the video mode used for standard-definition analog or digital television in Caribbean, Myanmar, Japan, South Korea, Taiwan, Philippines, Laos, Western Sahara, and most of the Americas (with the exception of Argentina, Paraguay and Uruguay).
Another development was the move from standard-definition television (SDTV) (576i, with 576 interlaced lines of resolution and 480i) to high-definition television (HDTV), which provides a resolution that is substantially higher.

Standard-definition television

480i is a shorthand name for the video mode used for standard-definition analog or digital television in Caribbean, Myanmar, Japan, South Korea, Taiwan, Philippines, Laos, Western Sahara, and most of the Americas (with the exception of Argentina, Paraguay and Uruguay).
The two common SDTV signal types are 576i, with 576 interlaced lines of resolution, derived from the European-developed PAL and SECAM systems, and 480i based on the American NTSC system.

576i

625-line720x576analogue
The other common standard, used in the other parts of the world, is 576i.
Because of its close association with the color encoding system, it is often referred to as simply PAL, PAL/SECAM or SECAM when compared to its 60 Hz (typically, see PAL-M) NTSC-color-encoded counterpart, 480i.

Interlaced video

The 480 identifies a vertical resolution of 480 lines, and the i identifies it as an interlaced resolution.
The US adopted the 525 line system, later incorporating the composite color standard known as NTSC, Europe adopted the 625 line system, and the UK switched from its idiosyncratic 405 line system to (the much more US-like) 625 to avoid having to develop a (wholly) unique method of color TV.

NTSC

analogNTSC-M30p
It is mandated by CCIR Systems M and J, which are usually paired with NTSC color - which led to the "NTSC" name being often inaccurately used to refer to this video mode.
As a consequence, the ATSC digital television standard states that for 480i signals, SMPTE "C" colorimetry should be assumed unless colorimetric data is included in the transport stream.

PAL-M

color
Other color encodings have also been used with System M, notably PAL-M in Brazil.
It is unique among analog 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), unlike all other countries which pair PAL with 625-line systems and NTSC with 525-line systems.

Enhanced-definition television

The term refers to devices capable of displaying 480-line or 576-line signals in progressive scan, commonly referred to as 480p (NTSC-HQ) and 576p (PAL) respectively, as opposed to interlaced scanning, commonly referred to as 480i (NTSC) or 576i (PAL).
