Leq represents the continuous noise level, equivalent in loudness and energy, to the fluctuating sound signal under consideration. Refer to LAeq.

a) A TV set, or a TV set specifically designed for closed circuit viewing (i.e., from a VTR) without the electronic capability to receive broadcast signals. b) A hardware device that displays the images, windows, and text with which you interact to use the system. It is also called a video display terminal (VDT). c) Program that controls the operation of a microcomputer system and allows user to run programs, examine and modify memory, etc.
Industry:Software
a) A television system that limits the recording or transmission of useful picture information to about three-quarters of the available vertical picture height of the distribution format (e.g., 525-line) in order to offer program material that has a wide picture aspect ratio. b) Term generally used for the form of aspect ratio accommodation involving increasing vertical blanking. See Blanking Adjustment.
Industry:Software
A separate playback head on some tape recorders that makes it possible to listen to the material on the tape an instant after it has been recorded and while the recording is still in progress.
Industry:Software
a) A defined set of constraints on the values which may be taken by some parameters within a particular profile. A profile may contain one or more levels. b) In MPEG-2, a range of picture parameters. c) Defines the bounds of the coding parameters, such as resolution, bit rate, etc. within each profile. The variation of performance is inherently wide in a profile.
Thus, levels have been defined in order to set reasonable constraints.
Industry:Software
A set of outputs from a switcher or video recorder for the specific purpose of feeding video monitors (although not limited to that purpose). These include preview, individual M/Es, DSK, and bus rows. The AVC also provides monitor outputs for RGB signals, aux bus selections, and switcher status information.
Industry:Software
As in a book library, it is somewhere one might keep effects, i.e., on a disk or collection of disks, hence a library of canned effects.
Industry:Software
The cable that connects the monitor to the workstation to provide power to the monitor. It has a male connector on one end and a female connector on the other.

A light valve projector uses a bulb as the source of light. The valve technology changes the color and intensity of the source to form the picture. Film or slide projectors are examples of light valve technology. The Digital Micro-Mirror Device (DMD) also known as the Digital Light Processor (DLP), the Image Light Amplifier (ILA), and LCD are all examples of electronic light valve technology. Obtaining black in a picture produced by a light valve projector requires the ability to shut the light off in particular areas of the picture. Shutting light off in a small area is actually rather difficult. Consequently, the real picture contrast ratio of a number of these projectors is rather poor.
