Which organization selected the 8 level vestigial sideband as the terrestrial transmission technology?

• A. Advanced Television Systems Committee
• B. Digital Video Interface Association
• C. Internet Television Association
• D. National Cable Association

Answer: (A)

The concept being tested is which organization is responsible for selecting the transmission method used for terrestrial digital TV. The 8-level vestigial sideband refers to the 8-VSB modulation chosen for over-the-air broadcasts in the ATSC standard. That choice was made by the Advanced Television Systems Committee, the group that developed and published ATSC. This organization determined that 8-VSB best fits a 6 MHz broadcast channel and provides a practical balance of data rate and robustness for terrestrial transmission in North America. The other entities listed are not standards bodies for this technology—one is a display-interface standard, another is not a recognized standards organization, and the last is a trade association, not a standards body responsible for terrestrial broadcast modulation.
