This standard describes a serial digital interface

for 525/60 and 625/50 digital television equipment

operating with either 4:2:2 component signals or 4fsc

composite digital signals. This standard has application

in the television studio over lengths of coaxial

cable where the signal loss does not exceed

an amount specified by the receiver manufacturer.

Typical loss amounts would be in the range of 20 dB

to 30 dB at one half the clock frequency with appropriate

receiver equalization. Receivers designed to

work with lesser signal attenuation are acceptable.
