Vestigial side band. VSB is a digital frequency modulation technique used to send data over a coaxial cable network. Used by Hybrid Networks for upstream digital transmissions, VSB is faster than the more commonly used QPSK, but it's also more susceptible to noise.

Vestigal Side Band Watt (energy per unit time, one joule per second)

A means of digital signal transmission in which the binary numbers are converted to symbols which modulate a"carrier" on eight distinct amplitudes or levels. The 8VSB method of digital signal modulation was chosen by the ATSC and thus adopted by the FCC as the standard for terrestrial digital signal transmission. 8VSB is a very robust method of digital signal transmission particularly suited to terrestrial broadcast.

An acronym for visible satellite imagery.
