S-VHS:

Super-VHS is the technological successor to the VHS format.  The
S-VHS format has digital freeze frame capabilities, higher
resolution than VHS (400+ vs. 240 lines), 4 audio channels vs. 2
for VHS, high fidelity audio as a standard feature, better video
and audio signal/noise ratio, improved contrast with detail, and
wider Y/C separation for dot interference elimination.  Since the
cost of S-VHS and VHS recorder, editing, and camcorder systems of
comparable features are virtually the same, these advantages of
S-VHS come at the expense of only a slightly higher cost for
recording tapes.  If S-VHS begins to penetrate the consumer
market and production of S-VHS tapes expands, these costs are
also likely to fall.
