A method by which material previously recorded on one track of a tape may be rerecorded on another track while simultaneously adding new material to it.
Industry:Software
A) Depressing a button causing some change while a switcher is transitioning. b) Selecting a tape edit point while VTR is moving.
Industry:Software
The process by which a magnetised sample of magnetic material tends to demagnetize itself by virtue of the opposing fields created within it by its own magnetization. Self-demagnetization inhibits the successful recording of short wavelengths or sharp transitions in a recorded signal.
Industry:Software
Device that ensures audio and video signals from varying sources are coordinated by timing them against a reference signal and advancing or delaying them as needed.
Industry:Software
A hypothetical decoder that is conceptually connected to the output of the encoder. Its purpose is to provide a constraint on the variability of the data rate that an encoder or editing process may produce (ISO13818-2 Annex C). This postulates the existence of a buffer in the receiver and a prediction mechanism in the encoder. This mechanism will predict the buffer fullness due to the constant fill from the constant bit rate (CBR) stream and the variable empty due to the variation in decoder bit demand. This latter factor can be controlled at the encoder by varying the quality of the encoding process (quantization factor, mainly).

In 1992, Intel introduced the Peripheral Component interface bus specification. PCI, a high-speed interconnection system that runs at processor speed, became compatible with the VL bus by its second release in 1993. PCI includes a 64-bit data bus and accommodates 32-bit and 64-bit expansion implementations. PCI is designed to be processor-independent and is used in most high-speed multimedia systems. PCI is designed so that all processors, co-processors, and support chips can be linked together without using glue logic and can operate up to 100 MHz, and beyond. PCI specifies connector pinout as well as expansion board architecture.

A) An image drawn on a CRT display remains visible only for a few milliseconds (the persistence of the screen phosphor), unless it is redrawn continuously. This process is called display refresh or screen refresh. Different displays use different refresh rates, but display refresh is normally required between 60 and 80 times a second to avoid any visible screen flickering. 75 times a second is a common refresh rate. In general, a higher refresh rate results in a more stable appearing display. b) Process of restoring the charge in a dynamic memory. Refresh logic must rewrite the contents of the complete RAM periodically (typically 2 ms), called refreshing the memory. See Dynamic Memory.
Regenerative Pulse Distribution Amplifier (Regenerative Pulse DA) – Reconstructs the signal and allows for adjustment of delay. Also see Linear Pulse DA.
Industry:Software
Video producing equipment such as cameras, tape recorders, or character generators.

One of two fields that comprise a frame of interlaced video.
Each line of a top field is spatially located immediately above the corresponding line of the bottom field.
