Audio Terminology And Definitions Dictionary

 

16 x 9 This is the standard scr screen that has 1.78 units of horizontal width to 1 unit of vertical height. All current TVs support this aspect ratio. TV programming or video content transmitted or fed to a TV that is not in the 16x9 aspect ratio will appear on the screen either with black bars on the top and bottom of the image ("letterboxing") or black bars on either side of the image ("pillarboxing"). "Windowboxing," another strategy for displaying 16 x 9 content on a screen that does not have a 16 x 9 aspect ratio, centers a slightly smaller image on the screen surrounded by a black border on all four sides. 

 

3LCD  Technology used in many video projectors that employs three LCD chips (one for each primary color: green, blue, and red) to produce an image.

 

480i An interlaced image with 480 lines of vertical resolution scanned alternately—odd lines first, then even lines. 480i is commonly referred to as "standard video resolution."

 

480p  480p images contain 480 lines of vertical resolution scanned. 480p is similar to the resolution of standard broadcast TV (and is referred to as SDTV, or Standard Definition Television), but the image is scanned progressively, rather than in alternate fields.

 

4k Resolution The term 4K refers to one of two high-definition resolutions: 3840 x 2160 pixels or 4096 x 2160 pixels. 4K is four times the high-definition resolution of 1080p (1920x1080 pixels), which is currently one of the primary consumer high-definition resolution standards.

 

720p  A720p image contains 1280 pixels displayed across the screen horizontally and 720 pixels displayed down the screen vertically, yielding720 progressively displayed pixel rows on the screen. This means that all 720 pixel rows are displayed at all times. Although 720p is high-definition, it takes up less bandwidth than 1080i or 1080p.

 

8k Resolution  8K resolution refers to an image with 7680 x 4320 pixels (or 4320p). It is effectively sixteen times more detailed than the current 1080p resolution standard. NHK's proposed Super Hi-Vision broadcast format follows this 8k standard. In addition, Super Hi-Vision provides for up to 22.2 channels of audio.

 

1080i  A broadcast standard that provides 1080 lines of vertical resolution scanned in an interlaced ("alternate field") manner, similar to a 480i image.

 

1080p  An image, usually from a Blu-ray disc, consisting of 1080 vertical lines of resolution scanned progressively.
