If the signal is at 0.Three volts (or 0 IRE) the image can be black. The sign area from 0 to 0.3 volts (-40 to 0 IRE models) is reserved for management indicators, the rest for image data.

The first 11.1 microseconds make up the horizontal blanking interval, or control signal, the following 52.46 microseconds make up the image sign. See HBI; VBI. NTSC: Acronym for National Television Standards Committee (or Never The same Color, when you want :-) Picture Signal: The 52.Forty six microseconds of sign following the management sign. The next chart lists frequency data for the "commonplace" provider sets. In an HRC (Harmonically Related Carrier) system, all image service frequencies are derived from a 6 MHz oscillator, so all channels except 5 and 6 can be 1.25 MHz decrease than normal. Channel Band Freq. Carrier Carrier Carrier Freq. It introduced channel bonding, which is like combining a number of lanes on a highway to make visitors transfer faster. The presence of a PPV movie channel or your system ensures you've gotten addressable converters. A revenue-enhancing system where customer's pay to look at a film or occasion on a "per view" basis.
