480i is the video mode used for standard-definition digital video [1] in the Caribbean, Japan, South Korea, Taiwan, Philippines, Myanmar, Western Sahara, and most of the Americas (with the exception of Argentina, Paraguay, and Uruguay).
In 4:2:0, the horizontal sampling is doubled compared to 4:1:1, but as the Cb and Cr channels are only sampled on each alternate line in this scheme, the vertical resolution is halved. The data rate is thus the same. This fits reasonably well with the PAL color encoding system, since this has only half the vertical chrominance resolution of NTSC.
SDTV resolution by nation: for historical reasons, different countries use either 480i or 576i as their standard-definition picture format. Standard-definition television (SDTV; also standard definition or SD) is a television system that uses a resolution that is not considered to be either high or enhanced definition. [1]
The term refers to devices capable of displaying 480-line or 576-line signals in progressive scan, commonly referred to as 480p and 576p (PAL/SECAM) respectively, as opposed to interlaced scanning, commonly referred to as 480i (NTSC) or 576i (PAL, SECAM). High-motion is optional for EDTV. [1]
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.
This is completely untrue. 480i is a description for a digital video system whereas NTSC or 525 line refers to an analogue video system. One can easily be converted to the other but they are not the same. 86.143.181.133 17:02, 2 August 2009 (UTC) Especially as the analogue NTSC system specified 486 active lines and would thus be 486i.
