Time Base Corrector. Video device that allows to re-generate (with no default) the sync. of a video signal from a jittery, noisy source (E.g. VCR).
Transmission Control Protocol (TCP/IP: by Internet Protocol); can be also used to monitor or control some devices. Compare to UDP.
Thunderbolt (originally codenamed Light Peak) is an interface for connecting peripheral devices to a computer via an expansion bus. Thunderbolt essentially combines PCI Express and DisplayPort into a new serial data interface that can be carried over longer and less costly cables. There are existing DisplayPort adapters for DVI, dual-link DVI, HDMI, and VGA output from the Thunderbolt port, showing broad compatibility of this new connector.
Video (TV scan) device that converts encoded Composite or Y/C signals into encoded Composite or Y/C signals but with different standards. This operation is made with no changes in the Horizontal and the Vertical scan frequencies (E.g. PAL to SECAM).
HDTV standard, for Analog YUV & RGB embedded Sync on each on the 3 channels. The 3 “steps” levels are -0,3v, 0v on 751 load. Allows for syncing of higher frequencies than BLACKBURST.
Transistor to Transistor Logic.
User Datagram Protocol (UDP/IP: by Internet Protocol Layer4); can be also used to monitor or control some devices. Compare to TCP.
An audio input/output where one of the two output terminals is at ground potential.
Ultra high Definition Television. A UHDTV resolution consists a computer format between 2560 x 1440 to 7680 x 4320 pixels.
Underwriter's Laboratories (U.S.A.)
Output image size. In Underscan mode, the entire image often appears as a rectangle centered on the display screen with a black border around it. Compare to OVERSCAN.
Device that converts a computer graphics image into a Higher (up) resolution computer format, by changing the horizontal and the vertical scan rates.
Universal Serial Bus, for computer peripherals.
In computing, a Uniform Resource Locator (URL) specifies where a known resource is available and the mechanism for retrieving it. It is also referred to as a Universal Resource Locator and in many technical documents and verbal discussions it is often used as a synonym for URI(Uniform Resource Identifier).
Sometimes called DR, DB or PR, PB. It is the difference of color versus the white (Y) Luminance. U=DR=R-Y and V=DB=B-Y (see Component).
Ultra eXtended Graphic Array. Non-interlaced. - Standard computer format consisting of 1600 x 1200 pixels. The aspect ratio is 4:3.
see refresh rate.
Video Electronics Standards Association. Organization that sets format standards for computer displays.
Video Graphics Array. Analog computer format (first introduced by IBM®) with Horizontal & Vertical separated sync. VGA is a 640 x 480 resolution at 60 HZ or 70 Hz (non-interlaced vertical scan rate).
Amplifier used for video signals. Enables a signal to be transmitted over a long distance (see Booster).
see Scan Converter.
TV/Video system also called TV or HDTV standard. The main worldwide TV standards are PAL, SECAM and NTSC.
