A proprietary audio compression algorithm from Scientific-Atlanta, used for satellite links.
Industry:Software
A camera tube in which the optical image falls on a photo-emissive cathode which emits electrons that are focused on a target at high velocity. The target is scanned from the rear by a low-velocity electron beam. Return beam modulation is amplified by an electron multiplier to form an overall light-sensitive device.
Industry:Software
The interface used to communicate with the system after it is powered up, but before it is booted up and running IRIX.
Industry:Software
A term used to describe a picture condition in which vertical or nearly vertical lines have a sawtooth appearance. The result of scanning lines starting at relatively different points during the horizontal scan.
Industry:Software
Empty channel spaces in the frequency allocation table to which broadcast channels cannot be assigned due to potential interference. The most obvious one is the co-channel taboo: two different television or radio stations cannot operate on the same frequency in the same geographical area. Other taboos cover geographical spacing for adjacent channels and for “images” (spurious frequencies akin to aliases) that are caused by reception in existing television sets. The taboos effectively knock out much of the UHF television band, so some ATV proponents wonder whether they might be too strict.
Industry:Software
A device developed in Germany which permits audio and video signals to be recorded on magnetic tape.
Industry:Software
Jitter is a random aberration in the time period due to noise or time base instability. Pick-off means sample point.
Industry:Software
In a uniformly magnetised sample of magnetic material, the product of the residual flux density and the cross-sectional area.
Residual flux is indicative of the output that can be expected from a tape at long wavelengths.
Industry:Software
Signals which endure for a brief time. These may include overshoots, damped sinusoidal waves, etc., and, therefore, additional qualifying information is necessary.
Industry:Software
One or more of several image orthicon impairments that have been referred to as “Orthicon Effect” as follows: edge effect, meshbeat or Moiré, ghost, halo, burned in image. It is obviously necessary to indicate specifically the effects experienced and, therefore, it is recommended that use of this term be discontinued.
