Most televisions use overscanning, resulting in some of the video being lost beyond the edges of the screen. Underscanning modifies the video timing so that the entire video signal appears in a rectangle centered on the television screen with a black border. The resolutions for square-pixel underscan and overscan images are: NTSC overscan: 640 x 480 PAL overscan: 768 x 576 NTSC underscan: 512 x 384 PAL underscan: 640 x 480.
Industry:Software
Rough edit decision list made by screening original materials, but without actually performing edits.
Industry:Software
A horizontal line in the vertical interval that is sometimes used to evaluate the amount of noise introduced in a certain part of the transmission path. A line is reinserted (and is therefore relatively noise free) at one end of the transmission path of interest. This ensures that any noise measured on that line at the other end was introduced in that part of the path.
Industry:Software
Four-digit value generated by a signature analyzer, which is used to characterize data activity present on a logic node during a specific period of time.
Industry:Software
The finest moments of time that can be perceived in a particular system. It is not the same as dynamic resolution, which is spatial resolution when an image is changing. As an example, suppose a spoked wheel is turning. If the spokes are a blur when the wheel is not turning, the system has poor static resolution; if they are clear, it has good static resolution (for the spokes). If they are a blur when the wheel is turning, the system has poor dynamic resolution and poor temporal resolution.
If they are clear when the wheel is turning, the system has good dynamic resolution. If, though clear, they appear to be stationary, or turning in the wrong direction, or turning at the wrong speed, or flashing rapidly in different positions so it is impossible to tell which way or at what speed they are turning (a temporal blur), the system has poor temporal resolution. A great deal of evidence indicates that the human visual system cannot simultaneously perceive high spatial resolution and high temporal resolution.
Industry:Software
Deleting the least-significant digits of a quantity and applying some rule of compensation and correction to the part retained.
Industry:Software
To reduce a window to an icon for later use. In Windows® it is called “minimize.”
Industry:Software
a) A pickup pattern which is more sensitive to sounds arriving from one direction than from any other. b) Wire or group of wires in which data flows in only one direction. Each device connected to a unidirectional bus is either a transmitter, or a receiver, but not both.
