'''16VSB''' is an abbreviation for 16-level vestigial sideband modulation, capable of transmitting four bits (2<sup>4</sup>=16) at a time.<br />
<br />
==How it works==<br />
Other slower but more rugged forms of VSB include [[Physics:2VSB|2VSB]], [[Physics:4VSB|4VSB]], and [[Physics:8VSB|8VSB]]. 16VSB is capable of twice the data capacity of 8VSB; while 8VSB delivers 19.39 Mbit/s (Megabits per second) in a 6-MHz [[Engineering:Television|television]] channel, 16VSB could deliver 38.78 Mbit/s, while making the sacrifice of being more prone to transmission error.<br />
<br />
==History==<br />
While 8VSB is the ATSC digital broadcast modulation format, 16VSB was planned for [[Engineering:Electrical cable|cable]] distribution. 16VSB is about twice as susceptible to noise, therefore less suitable than 8VSB for [[Engineering:Broadcasting|broadcast]], but well suited to the [[Physics:Signal-to-noise ratio|signal-to-noise ratio]] of hybrid fiber-coax distribution, allowing twice as much programming in a 6-MHz channel.<br />
<br />
==Technological obsolescence==<br />
As of 2007, a majority of cable companies have chosen to extend their existing [[Quadrature amplitude modulation|quadrature amplitude modulation]]-based systems to carry [[Engineering:Digital television|digital television]] rather than adopting any form of VSB. It is probable that 16VSB has been replaced by ''Digital Transmission Standard For Cable Television'' <ref>[http://www.scte.org/documents/pdf/Standards/ANSISCTE072006.pdf ANSI/SCTE 07 2006: Digital Transmission Standard For Cable Television]</ref> a cable standard that defines 64QAM and 256QAM transmission for digital cable.<br />
