Type of transmission where only a part of the available transponder is used for the signal, allowing the satellite operator to sell the remaining space on the transponder to other uplinkers. SCPC is typically used for feeds rather than for direct programming.
The advantage of SCPC over MCPC is that the signals uplinked to the same transponder can be transmitted up to the satellite from different locations.
Industry:Software
Interconnect consisting of three wires. One wire transports luminance while the other two wires each transport a colordifference signal. This system is commonly used for connecting equipment in a “component facility” because it is more compatible with non-VTR video sources, time-base correctors, displays, and monitoring equipment.
Industry:Software
A device designed to wind and clean magnetic tape in order to restore it to a quality that approaches the condition of a new tape, providing the tape has not been physically damaged.
Industry:Software
A series of tests that automatically check hardware components of a system each time it is turned on.
Industry:Software
The number of discrete sample measurements made in a given period of time. Often expressed in megahertz for video.
These samples are then converted into digital numeric values to create the digital signal.
Industry:Software
A spatial resolution smaller than that of a pixel. Although digital images are composed of pixels, it can be very useful to resolve image detail to smaller than pixel size, i.e., sub-pixel. For example, the data for generating a smooth curve on television needs to be created to a finer accuracy than the pixel grid itself, otherwise the curve will look jagged.
Again, when tacking an object in a scene or executing a DVE move, the size and position of the manipulated picture must be calculated, and the picture resolved, to a far finer accuracy than the pixels, otherwise the move will appear jerky.
Industry:Software
To make a file system that is accessible from a specific directory on a workstation temporarily inaccessible.
Industry:Software
A self-checking code employing binary digits in which the total number of 1s (or 0s) in each code expression is always even or always odd. A check may be made for even or odd parity as a means of detecting errors in the system.
Industry:Software
a) A series of horizontal scan lines that make up a display. The scanned (illuminated) area of the cathode-ray picture tube. b) A set of scanning lines; also the type of image sampling using scanning lines (as in raster scanning).
Industry:Software
A TV transmitter network in which all the transmitters use the same frequency. The coverage areas overlap.
Reflections are minimized by guard intervals. The transmitters are separated by up to 60 km. The special feature of these networks is efficient frequency utilization.
