480i
open-in-new
<p>480i is the <a href="/facts/Video/F1AV8ben">video</a> mode used for <a href="/facts/Standard-definition_television/dvqEXg2A">standard-definition</a> <a href="/facts/Digital_video/xsn9omqG">digital video</a> in the <a href="/facts/Caribbean/zRI9aMCh">Caribbean</a>, <a href="/facts/Japan/U5mz0SRT">Japan</a>, <a href="/facts/South_Korea/pCobAaVw">South Korea</a>, <a href="/facts/Taiwan/VcJoUD8w">Taiwan</a>, <a href="/facts/Philippines/ARpmxXQV">Philippines</a>, <a href="/facts/Myanmar/zcqQH2oE">Myanmar</a>, <a href="/facts/Western_Sahara/xAmSkuJl">Western Sahara</a>, and most of the <a href="/facts/Americas/hEuUTL4K">Americas</a> (with the exception of <a href="/facts/Argentina/aFSA5bAk">Argentina</a>, <a href="/facts/Paraguay/sbzfv4Rl">Paraguay</a>, and <a href="/facts/Uruguay/X6V0apCb">Uruguay</a>). The other common standard definition digital standard, used in the rest of the world, is <a href="/facts/576i/KXywE4Ps">576i</a>. </p><p>It originated from the need for a standard to digitize analog <a href="/facts/525_lines/NTPQFv9B">525 line</a> TV (defined in <a href="/facts/Rec._601/rBCG7yEf">BT.601</a>) and is now used for digital TV broadcasts and home appliances such as game consoles and DVD disc players. </p><p>The <i>480</i> identifies a vertical resolution of 480 lines, and the <i>i</i> identifies it as an <a href="/facts/Interlaced_video/YBk246TF">interlaced</a> resolution. The <a href="/facts/Refresh_rate/7mGJs7Dz">field rate</a>, which is 60 <a href="/facts/Hertz/6Wshj5qm">Hz</a> (or 59.94 Hz when used with NTSC color), is sometimes included when identifying the video mode, i.e. 480i60; another notation, endorsed by both the <a href="/facts/International_Telecommunication_Union/Yn8UKKkw">International Telecommunication Union</a> in <a href="/facts/Rec._601/rBCG7yEf">BT.601</a> and SMPTE in <a href="/facts/SMPTE_259M/JWHJAGsd">SMPTE 259M</a>, includes the <a href="/facts/Frame_rate/sbRkc9xa">frame rate</a>, as in 480i/30. </p><p>Although related, it should not be confused with the analog "<a href="/facts/525_lines/NTPQFv9B">525 lines</a>" resolution, mandated by <a href="/facts/CCIR_System_M/arU7p0qI">CCIR Systems M and J</a> and usually paired with <a href="/facts/NTSC/HYWIvxCR">NTSC</a> color. This association explains why 480i is sometimes inaccurately called "NTSC", even though NTSC only exists in the analog domain. </p>
