An undesired increase in amplitude of a portion of the composite video signal relative to that of another portion. Also, a greater than proportional change in the output of a circuit for a change in input level.
For example, expansion of the sync pulse means an increase in the percentage of sync during transmission.

EDO DRAM allows read data to be held past the rising edge of CAS (Column Address Strobe) improving the fast page mode cycle time critical to graphics performance and bandwidth. EDO DRAM is less expensive than VRAM.
Industry:Entertainment
A 625-line video standard that allows processing of component video quality digital signals by composite PAL equipment.
The signal can be distributed and recorded in a composite digital form using D2 or D3 VTRs.

a) Extended (or Enhanced) Definition Television is a proposed intermediate television system for evolution to full HDTV that offers picture quality substantially improved over conventional 525-line or 625-line receivers, by employing techniques at the transmitter and at the receiver that are transparent to (and cause no visible quality degradation to) existing 525-line or 625-line receivers. One example of EDTV is the improved separation of luminance and color components by pre-combing the signals prior to transmission.
Also see Improved Definition Television. b) Specifically, a video format with sampling frequencies 18 MHz (Y), 4.5 MHz (C), and resolution 960 pixels by 576 lines (Y), 480 pixels by 288 lines (C).

Extra key inputs that may be accessed by keyboard that do not appear on the bus rows. Traditionally, these inputs are used only for luminance keys, such as simple character generators or titling cameras; however, they are not limited to this on Ampex switchers. These are sources 9 and 0 on 4100 series switchers, and 31 and 32 on AVC switchers.

The next stop in creating a boundary rep solid is to “extrude” the silhouette. Extrusion (or sweeping) is a method of dragging a polygon through space in order to define a solid. There are typically two kinds of extrusion: translational and rotational.
