Information about 16vsb
16VSB is an abbreviation for 16-level vestigial sideband modulation, capable of transmitting four bits (24=16) at a time.
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 Mbit/s (Megabits per second) in a 6-MHz television channel, 16VSB could deliver 38.78 Mbit/s, while making the sacrifice of being more prone to transmission error.
While 8VSB is the ATSC digital broadcast modulation format (used in the United States and a few other countries), 16VSB was planned for cable distribution. 16VSB is about twice as susceptible to noise, therefore less suitable than 8VSB for 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.
However, as of 2004, cable companies have chosen to extend their existing quadrature amplitude modulation-based systems to carry digital television rather than adopting any form of VSB.
Quadrature amplitude modulation (QAM) is a modulation scheme which conveys data by changing (modulating) the amplitude of two carrier waves.

abbreviation (from Latin brevis "short") is a shortened form of a word or phrase. Usually, but not always, it consists of a letter or group of letters taken from the word or phrase. For example, the word "abbreviation" can itself be represented by the abbreviation "abbr.

In telecommunications, 2VSB is an abbreviation for 2-level vestigial sideband modulation, a transmission method capable of transmitting one bit (21=2) at a time.

4VSB is an abbreviation for 4-level vestigial sideband modulation, capable of transmitting two bits (22=4) at a time.
Other faster but less rugged forms include 8VSB and 16VSB. While 2VSB is more rugged, it is also slower.
