Spectral Interleaving
Cohabitation of Luminance & Color information in the same spectrum.

This is made possible by placing the color subcarrier, with its derived spectrum, half way between the 227th & 228th Luminance spectral lines. 
 

 
Broadcast Spectrum Shaping
NTSC Broadcast signal uses Vestigial SideBand (VSB) transmission, with properly bandlimited "I" & "Q" chroma information. 
Note also, the aural carrier @ 4.5 MHz. In practice, this is inserted as a highlevel aural transmitter output at the transmitting antenna. 

The Video information is Amplitude Modulation (AM); the Aural information is Frequency Modulation (FM).

 
VTR/VCR Recording Spectrum
Note that Video information is recorded on magnetic tape as a FM signal. The sound recorded as conventional baseband (longitudinal) magnetic recording. Also. in the multi head "HiFi" VHS VCRs, in addition, FM sound recording is used.

Numerical Relationships
 
Video Resolution verses Bandwidth
 
Comb Filtering
This Analog Signal Processing (ASP) is used for "apparent" Enhanced Horizontal Resolution, as well as, improved Video Signal to Noise Ratio (SNR).

There is, however, a reduction in Vertical Resolution; for which certain non-linear circuits attempt to compensate.

 
Genlock
Genlock is where several video sources are synchronized with each other, e.g., either a master sync generator or a camera or a VTR/VCR.

However it cannot be used synchronize a VTR/VCR to an external source; a TimeBase Corrector (TBC) is used for that purpose.
