Display resolutionThe 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 can be an ambiguous term, especially as the displayed resolution is controlled by different factors in cathode-ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays.
PALColor encoding system for analogue televisionAnalog television encoding systems by nation (at time of digital switchover, where applicable): NTSC SECAM PAL No infoPAL (an acronym for Phase Alternating Line) is a colour encoding system for analogue television. It was one of three major analogue colour television standards, the others being NTSC and SECAM.
AmpexAmpex Data Systems Corporation is an American electronics company founded in 1944 by Alexander M. Poniatoff as a spin-off of Dalmo-Victor. The name AMPEX is an acronym, created by its founder, which stands for Alexander M. Poniatoff Excellence. Ampex operates as Ampex Data Systems Corporation, a subsidiary of Delta Information Systems, and consists of two business units.
Display aspect ratioThe display aspect ratio (DAR) is the aspect ratio of a display device. It is a proportional relationship between the physical width and the height of the display. It is expressed as a pair of integer 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.Video file formatA video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9) alongside audio data in an audio coding format (e.g. Opus).
Refresh rateIn reference to terminology originating with cathode-ray tubes (CRTs), the refresh rate, also known as vertical refresh rate, vertical scan rate or vertical frequency, is the number of times per second that a raster-baseddisplay device displays a new image. This can be independent of frame rate, which describes how many images are stored or generated every second by the device driving the display.ITU-TThe International Telecommunication Union Telecommunication Standardization Sector (ITU-T) is one of the three Sectors (branches) of the International Telecommunication Union (ITU).
Streaming mediaStreaming media is the method by which multimedia data is delivered through a network for playback using a digital media player or media player software. Media is transferred in a stream of packets from a server to a client and is rendered in real-time or near real-time; this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content.
Color reproductionColor reproduction is an aspect of color science concerned with producing light spectra that evoke a desired color, either through additive (light emitting) or subtractive (surface color) models. It converts physical correlates of color perception (CIE 1931 XYZ color space tristimulus values and related quantities) into light spectra that can be experienced by observers. In this way, it is the opposite of colorimetry.
Optical discAn optical disc is a flat, usually disc-shaped object that stores information in the form of physical variations on its surface that can be read with a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to be detected on the other side. They may contain analog or digital information, or a mixture of the two.
Radio broadcastingRadio broadcasting is the transmission of signals, especially audio, to receivers using radio waves over a wide area. Listeners require a broadcast radio receiver to receive these signals. "Terrestrial" broadcasts come from stations on land, and include AM and FM (both analog); and DAB (digital). Audio is also broadcast via satellite in both digital and analog, originating from a satellite in orbit around Earth.
Magnetic tapeMagnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape can record and play back audio, visual, and digital computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting.*As an Amazon Associate I earn from qualifying purchases.
