Digital Copy
A digital copy is a commercially distributed computer file containing a media product such as a film or music album. The term contrasts this computer file with the physical copy (typically a DVD, Blu-ray, Blu-ray 3D, or Ultra HD Blu-ray disc) with which the digital copy is usually offered as part of a bundle. It allows the disc's purchaser to acquire a single copy of the film on a digital device such as a personal computer, smartphone, tablet computer, or digital media player, and view it on those devices without requiring access to the physical media. "Digital copy" is also commonly referred to as "digital HD" (where it is referencing a high-definition or UHD digital copy). Features There are three types of a digital copy. The first is a copy made in advance and included on the disc. The second is created dynamically from the DVD content itself.

Stereophonic Sound
Stereophonic sound, commonly shortened to stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and the Internet.

Display Aspect Ratio
The display aspect ratio (DAR) is the Aspect ratio (image), aspect ratio of a display device and so the proportional relationship between the display size, physical width and the height of the display. It is expressed as two numbers separated by a colon (''x'':''y''), where ''x'' corresponds to the width and ''y'' to the height. Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10, and 16:9. To distinguish: * The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or Centimetre, cm (Display size). * The pixel aspect ratio, pixel aspect ratio (PAR) is calculated from the width and height of one pixel. * The storage aspect ratio, storage aspect ratio (SAR) is calculated from the numbers of pixels in width and height stated in the Graphics display resolution, display resolution. Because the units cancel out, all aspect ratios are unitless. Diagonal and area The size of a television set or computer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Display Resolution
The display resolution or display modes of a digital television, computer monitor, or other display device is the number of distinct pixels in each dimension that can be displayed.

It is usually quoted as ', with the units in pixels: for example, ' means the width is 1024 pixels and the height is 768 pixels. This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight". One use of the term ''display resolution'' applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, AMOLED, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pi ...
