Logical structure of a computer system.

a) Off-line storage of video/audio onto backup tapes, floppy disks, optical disks, etc. b) A collection of several files bundled into one file by a program (such as ar, tar, bar, or cpio) for shipment or archiving. This method is very reliable and can contain large amounts of data.

One of three essential components of a microprocessor. The other two are the registers and the control block. The ALU performs various forms of addition, subtraction, and logic operations, such as ANDing the contents of two registers or masking the contents of a register.

a) Artifacts can range from noise and snow, to spots. Anything that is visually wrong with the picture is an artifact. Artifacts however do not include picture errors caused by improperly adjusted displays. Artifacts are visual errors caused by the signal being sent to the display. b) A defect or distortion of the image, introduced along the sequence from origination and image capture to final display. Artifacts may arise from the overload of channel capacity by excess signal bandwidth. Artifacts may also result from: sampling effects in temporal, spatial, or frequency domains; processing by the transfer functions; compromises any inadequacies in the system employed; cascading of minor defects; basically any other departure of the total system from “complete transparency.” c) Visible (or audible) consequences of various television processes. Artifacts are usually referred to only when they are considered defects. Artifact elimination is often more apparent than quality increases such as resolution enhancement. d) Interference or other unwanted “noise” in video such as flickering, changes in color, and macroblocking. Some artifacts, such as macroblocking, can be remedied in video compression and some cannot. The quality of the finished product is, in large part, no better than the source material. See also Filter Artifacts, Impairments, and NTSC Artifacts.

Techniques by means of which something shot in one aspect ratio can be presented in another. The five currently used or proposed techniques are compared in the following table. It is also possible to combine techniques. Current ATV aspect ratio debates concentrate on the problems of presenting widescreen images to existing TV sets; the same problems (in an opposite direction) will occur when current aspect ratio images are presented on widescreen TV sets. In movie theaters, these problems are usually solved with movable drapes.
Industry:Entertainment
Electronic edit that replaces all previously recorded material with new audio and video and a new control track, starting at the edit point. Inserting a new control track allows for a constant speed reference throughout the entire tape.

Translates assembly language statements (mnemonics) into machine language.
Industry:Entertainment
Machine-oriented language. A program is normally written as a series of statements using mnemonic symbols that suggest the definition of the instruction. It is then translated into machine language by an assembler program.
Industry:Entertainment
Compression in which the encoding and decoding require different processing power (the encoding is normally more demanding).
