Editing 16VSB

{{Short description|Type of vestigial sideband modulation}}
{{Refimprove|date=September 2018}}
'''16VSB''' is an [[abbreviation]] for 16-level [[vestigial sideband modulation]], capable of transmitting four bits (2<sup>4</sup>=16) at a time.

==How it works==
Other slower but more rugged forms of VSB include [[2VSB]], [[4VSB]], and [[8VSB]]. 16VSB is capable of twice the data capacity of 8VSB; while 8VSB delivers 19.39&nbsp;Mbit/s (Megabits per second) in a 6-MHz [[television]] [[communications channel|channel]], 16VSB could deliver 38.78&nbsp;Mbit/s, while making the sacrifice of being more prone to transmission error.

==History==
While 8VSB is the [[ATSC Standards|ATSC]] digital broadcast modulation format, 16VSB was planned for [[Electrical cable|cable]] distribution. 16VSB is about twice as susceptible to [[signal noise|noise]], therefore less suitable than 8VSB for [[Broadcasting|broadcast]], but well suited to the [[signal-to-noise ratio]] of [[hybrid fiber-coax]] distribution, allowing twice as much programming in a 6-MHz channel.

==Technological obsolescence==
As of 2007, a majority of cable companies have chosen to extend their existing [[quadrature amplitude modulation]]-based systems to carry [[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 It is probable that 16VSB has been replaced by ''Digital Transmission Standard For Cable Television'' 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.
