480i is the shorthand name for a video mode. The i, which is sometimes uppercase, stands for interlaced, the 480 for a vertical frame resolution of 480 lines. For the method of incrementally displaying Raster graphics, see Interlace (bitmaps. The digitally transmitted horizontal resolution is usually 720 or 704 pixels with an aspect ratio of 4:3 and therefore a display resolution of 640 × 480 (VGA); that is standard-definition television (SDTV). Digital television (DTV is the sending and receiving of moving images and sound by discrete ( digital) signals in contrast to the analog signals used by In Digital imaging, a pixel ( pict ure el ement is the smallest piece of information in an image The aspect ratio of an Image is its width divided by its height The term Video Graphics Array ( VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987, but through its widespread
The field rate (not the frame rate) is usually (60/100. The field rate of an Interlaced video image is twice the effective Frame rate, since interlacing draws only half of the image (the odd- or even-numbered lines at Frame rate, or frame frequency, is the measurement of the Frequency (rate at which an imaging device produces unique consecutive images called frames The 1% ≈) 59. 94 hertz for color TV and can be rounded up to 60 Hz. The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. Television ( TV) is a widely used Telecommunication medium for sending ( Broadcasting) and receiving moving Images, either monochromatic There are several conventions for written shorthands for the combination of resolution and rate: 480i60, 480i/60 (EBU) and 480/60i. The European Broadcasting Union ( EBU; L'Union Européenne de Radio-Télévision ("UER" and unrelated to the European Union) is a confederation 480i is usually used in countries that conventionally use NTSC (North America, Japan), because the 525 transmitted lines at 60 hertz of analogue NTSC contain 480 visible ones. NTSC ( National Television System Committee) is the Analog television system used in the United States, Canada, Japan, Mexico 480i can be transported by all major digital television formats, ATSC, DVB and ISDB. Digital television (DTV is the sending and receiving of moving images and sound by discrete ( digital) signals in contrast to the analog signals used by For the chemical compound see Divinylbenzene. Digital Video Broadcasting ( DVB) is a suite of internationally accepted Integrated Services Digital Broadcasting (ISDB is a Japanese standard for Digital television (DTV and Digital radio used by the country's radio NTSC DVDs use 480i when high motion is desired, but for movies 24 progressive frames per second (480p) are used instead. DVD (also known as " Digital Versatile Disc " or " Digital Video Disc " - see Etymology)is High motion is the characteristic of video or film footage displayed possessing a sufficiently high frame rate (or field rate that moving images do not blur or strobe even when tracked 480p is the shorthand name for a video display resolution The p stands for Progressive scan, i The 480i resolution is used in most standard-definition TVs.
