An old CBS ATV proposal for delivery via two NTSC-capable DBS channels. One channel would carry a MAC signal of NTSC characteristics; the other would carry additional vertical resolution and widescreen panels. This was the first system to prove that widescreen seams could be rendered invisible.
Industry:Software
A strategy where cache data is always written into main memory when data is written by the CPU. The write-through is done through the cache system.
Industry:Software
A device that forces tape into intimate contact with the head gap, usually by direct pressure at the head assembly.
Industry:Software
Circuit with hysteresis used for input signals that are noisy or have slow transition times.
Industry:Software
A noise containing harmonics of 59.94 Hz, heard on television set speakers under certain signal and transmission conditions. One such condition is the transmission of electronically generated characters of high level and resolution greater than can be carried in NTSC. The ringing resulting when those signals hit an NTSC philtre causes the television carrier to momentarily disappear. Since the characters are within a television field, the rate of appearance and disappearance is a multiple of the field rate, 59.94 Hz.
Industry:Software
The amount of detail that can be perceived in the vertical direction; the maximum number of alternating white and black horizontal lines that can be counted from the top of the picture to the bottom.
It is not the same as the number of scanning lines. It is the number of scanning lines minus the VBI times the Kell factor (and, where appropriate, times the interlace coefficient).
Industry:Software
A boost which is greater at the centre frequency than either above or below it.
Industry:Software
Equipment for making a record of a video waveform so that the mapped images may be stored and subsequently retrieved as the video waveform.
Industry:Software
A) A selector on the display that changes state or initiates an action when you touch it on screen. You use soft keys to select test signals or a sub-window of functions or to enter a file name. b) A soft key’s function changes to match the block above it, in the bottom line of the screen.
c) The softening of a key edge by reducing the gain of the keyer.
