Hd Movie Wallpaper Biography
High-definition video or HD video refers to any video system of higher resolution than standard-definition (SD) video, and most commonly involves display resolutions of 1,280×720 pixels (720p) or 1,920×1,080 pixels (1080i/1080p). This article discusses the general concepts of high-definition video, as opposed to its specific applications in television broadcast (HDTV), video recording formats (HDCAM, HDCAM-SR, DVCPRO HD, D5 HD, AVC-Intra, XDCAM HD, HDV, and AVCHD), the Blu-ray Disc and the D-VHS video tape format.
From a historical perspective, the first electronic scanning format 405 lines was the first "high definition" television system as the previous mechanical systems had far fewer scanning lines.
From 1939, the US and other European countries experimented with 441 lines and 605 lines until the Federal Communications Commission (FCC) mandated 525 lines for the US from 1941. In wartime France, René Barthélemy experimented with higher definitions, reaching 1015 and even 1042 lines. Official French transmissions finally began with 819 lines from late 1949; however, this standard was abandoned in 1984 upon the adoption of 625-line colour on the TF1 network.
