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. |
