480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
The simple way to convert NTSC video to CIF is to capture every other field (e.g., the top fields) of interlaced video, downsample it by 2:1 horizontally to convert 704 samples per line to 352 samples per line, and upsample it vertically by a ratio of 6:5 vertically to convert 240 lines to 288 lines.
An enlargement of a small section of a 1024x768 (VESA XGA) resolution image; the individual pixels are more visible in its scaled form than its normal resolution.A video scaler is a system that converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as ...
720p (720 lines progressive) is a progressive HD signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HD (1.78:1). All major HD broadcasting standards (such as SMPTE 292M ) include a 720p format, which has a resolution of 1280×720.
Television standards conversion is the process of changing a television transmission or recording from one video system to another. Converting video between different numbers of lines, frame rates, and color models in video pictures is a complex technical problem.
Second, the HDTV-standard 1280 × 720 [127] (otherwise commonly described as "720p"), which offers an exact 16:9 aspect ratio with square pixels; naturally, it displays standard 720p HD video material without stretching or letterboxing and 1080i/1080p with a simple 2:3 downscale. This resolution has found some use in tablets and modern, high ...
Standard definition—480i, to maintain compatibility with existing NTSC sets when a digital television broadcast is converted back to an analog one [citation needed] —either by a converter box or a cable/satellite operator's proprietary equipment; Enhanced definition—480p, about the same quality as DVDs; High definition—720p; High ...
Movies shot at 24 frames-per-second (fps) are often encoded onto a DVD at 24 fps progressive. For telecine sources, most DVD players can do the 2:2 or 3:2 pulldown conversion dealing with deinterlacing internally, before feeding the output to a progressive 576p or 480p display. [8] [9]
