Slow, periodic variations in the speed of the tape, characterised by its effect on pitch. A measure of non-uniform movement of magnetic tape or other recording parts.
Industry:Software
A scanning process in which the distance from centre to centre of successively scanned lines is two or more times the nominal line width, and in which the adjacent lines belong to different fields. For a given number of active vertical lines per frame, and a given frame-rate, interlaced scanning provides system-limited definition for still images. Moving images, however, provide reduced perceived spatial definition.
Although the interlaced scanning field-rate at a multiple of the framerate could improve temporal resolution, this is seldom perceived. When scanning interlaced 2:1 in either capture or display mode, the lines constituting one frame of the image are scanned and/or presented in two successive fields one-half the lines in one field and the other half interleaved as the following field. In a system based upon a nominal 60 Hz, for example, the generation and presentation of the two fields in succession require a total of 1/30 sec per frame, with a continual temporal progression from start to finish of the scanning. Note: Interlaced scanning may be introduced in the original scanning for image capture, or may be developed from progressive scanning of the original.
Industry:Software
A) The final combining and enhancing of a video program’s audio tracks. b) Electronically improving the quality of an audio or video signal, such as by adding sound effects, laugh tracks, and captions.
Industry:Software
A pulse at field rate used in TV cameras. Its leading edge is coincident with the leading edge of the vertical blanking pulse and its duration may be 10.5 lines.
Industry:Software
The process of altering one or more pattern parameters. See Modifier.
Industry:Software
Term used for an ATV scheme that allows existing NTSC television sets to tune into the ATV signal and get pictures and sounds; also used to describe an MIT ATV scheme using blanking adjustment for aspect ratio accommodation and using various sub-channels to carry additional information but requiring a very complex receiver to recover that information. It is said to offer 600 lines of vertical and 660 lines of horizontal static luminance resolution, with reduced static diagonal resolution and with dynamic resolution comparable to NTSC. The term Receiver Compatibility, as it is usually used, allows some degradation in pictures from the highest NTSC quality, in the same way that the receiver-compatible NTSC colour system introduced cross-luminance to existing black-and white TV sets.
Industry:Software
Technology of less complexity than medium scale integration. Usually means less than ten gate functions in the IC.
Industry:Software
The management of multiple signals on one channel by alternately sending portions of each signal and assigning each portion to particular blocks of time.
Industry:Software
A) The length of the path along which tape and head are in intimate physical contact. b) A term used to signify the session (job) is finished.
Industry:Software
A) One compressed picture or block of audio.
b) Decoded AAU or a decoded picture.
