Data compression ratio is defined as the ratio between the uncompressed size and compressed size: [1][2][3][4][5] Thus, a representation that compresses a file's storage size from 10 MB to 2 MB has a compression ratio of 10/2 = 5, often notated as an explicit ratio, 5:1 (read "five" to "one"), or as an implicit ratio, 5/1.
Closed-circuit television (CCTV), also known as video surveillance, [1][2] is the use of closed-circuit television cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point, point-to-multipoint (P2MP), or ...
The 2024 FIA Formula 2 Championship is a motor racing championship for Formula 2 cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The championship is the fifty-eighth season of Formula 2 racing and the eighth season run under the FIA Formula 2 Championship moniker. It is an open-wheel racing category serving as the ...
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
Aspect ratio (image) The aspect ratio of an image is the ratio of its width to its height. It is expressed as two numbers separated by a colon, width:height. Common aspect ratios are 1.85:1 and 2.40:1 in cinematography, 4:3 and 16:9 in television, and 3:2 in still photography.
Dynamic modulus. Dynamic modulus (sometimes complex modulus[1]) is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). It is a property of viscoelastic materials.
ISO 6346 is an international standard covering the coding, identification and marking of intermodal (shipping) containers used within containerized intermodal freight transport by the International Organization for Standardization (ISO). [ 1 ] The standard establishes a visual identification system for every container that includes a unique ...
Density (computer storage) Density is a measure of the quantity of information bits that can be stored on a given physical space of a computer storage medium. There are three types of density: length (linear density) of track, area of the surface (areal density), or in a given volume (volumetric density).
