Refers to a transparent sheet of glass or acetate on which a “layer” or “level” of artwork is painted. Since the sheet is clear where there is no artwork, several sheets can be superimposed, allowing “automatic hiddensurface removal,” or simply, the “painter’s algorithm.”

A) The magnetised portion along the length of a videotape on which sync control information is placed. The control track contains a pulse for each video field and is used to synchronise the tape and the video signal. b) A synchronising signal on the edge of the tape which provides a reference for tracking control and tape speed. Control tracks that have heavy dropouts are improperly recorded and may cause tracking defects or picture jumps. c) A signal recorded on video tape to allow the tape to play back at a precise speed in any VTR. Analogous to the sprocket holes on film.

Cell is a compression technique developed by Sun Microsystems. The compression algorithms, the bit stream definition, and the decompression algorithms are open; that is, Sun will tell anybody who is interested about them. Cell compression is similar to MPEG and H.261 in that there is a lot of room for value-add on the compressor end. Getting the highest quality image from a given bit count at a reasonable amount of computation is an art. In addition the bit-stream completely defines the compression format and defines what the decoder must do and there is less art in the decoder. There are two flavours of Cell: the original called Cell or CellA, and a newer flavour called CellB.

Sony’s wired edit control protocol, also called LANC (Local Application Control), which allows two-way communication between a camcorder or VCR and an edit controller such as the Thumbs Up.
Control-L allows the controller to control the deck (fast forward, play, etc.) and also allows the controller to read the tape position (tape counter) information from the deck.

A network where a central server controls services and information; the server is maintained by one or more individuals called network administrators. On a centralised network that uses NIS, this server is called the NIS master, and all other systems on the network are called NIS clients. See also Network Administrator, NIS, NIS Client, NIS Domain, and NIS Master.
