Like the Apple IIe, the C64 can also output a composite video signal ( avoiding the RF modulator ) that can be plugged into a specialized monitor for a sharper picture.
12.
Image synchronization is achieved by transmitting negative-going pulses; in a composite video signal of 1 volt amplitude, these are approximately 0.3 V below the " black level ".
13.
"' Colorburst "'is an analog video, composite video signal generated by a video-signal generator used to keep the chrominance subcarrier synchronized in a color television signal.
14.
Since Analog video recordings use frequency modulation for the luminance part ( composite video signal in direct colour systems ), which keeps the tape at saturation level, audio style noise reduction is unnecessary.
15.
In this mode, S-Video chrominance ( C ) and luminance ( Y ) signals replace the red and green channels, while an equivalent composite video signal is output on the blue channel.
16.
Dot crawl is most visible when the chrominance is transmitted with a high bandwidth, so that its spectrum reaches well into the band of frequencies used by the luminance signal in the composite video signal.
17.
Because this system outputs a standard NTSC composite video signal and the used parts are somewhat easy and inexpensive to find, it has become a popular choice for fitting thermal night vision to other vehicles.
18.
The Raspberry Pis can also generate 576i and 480i composite video signals, as used on old-style ( PAL-BGHID, PAL-M, PAL-N, NTSC and NTSC-J.
19.
In some analog video formats ( Frequency modulation is the standard method for recording the luminance part of the signal, and is used to record a composite video signal in Direct colour systems ), e . g.
20.
A number of noise reduction techniques can be used to reduce the impact of tape hiss, including DBX, or, in case of video recording, frequency modulation of either the composite video signal, or the luminance part.
