1.12 How does the resolution of CED compare to the VHS, LaserDisc,and DVD video formats?

RCA didn't use Lines of Resolution in their CED specifications, but a
bandwidth of 3 MHz translates to about 240 Lines, the same resolution as
VHS, but less than the 425 Lines of LaserDisc and 500 Lines of DVD. The
subjective evaluation of people familiar with all these formats is that
CED is better than VHS, but not as good as LaserDisc or DVD. CED does
pale in comparison to modern LaserDisc and DVD players, but in 1981 there
wasn't a lot of difference, because LaserDisc technology was young, and
at that time RCA had superior mastering techniques. A comparative review
of the Zenith VP2000 CED player and the Magnavox VH8000 LaserDisc player
in the July '81 issue of _Popular Electronics_ rated the Zenith unit
better in Video and Audio Signal-to-Noise ratios, but lower in total
Video bandwidth.
