8VSB is the modulation method used for broadcast in the ATSC digital television standard. ATSC and 8VSB modulation is used primarily in North America; in contrast, the DVB-T standard uses COFDM. A modulation method specifies how the radio signal fluctuates to convey information.

2020年10月22日 · Advanced Television Systems Committee Television. 8VSB Modulation. 8VSB Modulation is a special kind of PAM Modulation. Each channel has a single carrier signal on the left of the signal. 8VSB uses digital amplitude modulation with 8 distinct amplitude levels representing 3 digital bits.

Terrestrial (local) broadcasters use 8VSB modulation that can transfer at a maximum rate of 19.39 Mbit/s, sufficient to carry several video and audio programs and metadata.

Simply put, 8-VSB is the RF modulation format utilized by the DTV (ATSC) digital television standard to transmit digital bits over the airwaves to the home consumer.

2009年5月8日 · The other highlights of ATSC that are useful to understand is that it uses 8VSB modulation -- this fact and $3 will get you a cup of coffee -- and that each 6MHz channel has a dedicated 19.39...

8VSB transmits data in a way that allows for error correction, ensuring better reception and fewer artifacts in the video display. The '8' in 8VSB refers to the eight distinct signal states used to represent digital data, enhancing the capacity for information transmission.

2023年2月23日 · 8VSB, which stands for 8-level vestigial sideband modulation, is the key to unlocking the magic of over-the-air digital television broadcast in North America. Unlike its European counterpart, DVB-T, which uses COFDM, 8VSB is the preferred modulation method of the ATSC digital television standard.

2011年1月26日 · 8-VSB is a single carrier 8-level vestigial sideband modulation method adopted for OTA broadcast of the ATSC DTV standard in the USA and Canada. In the 6MHz channel used for broadcast ATSC, 8-VSB carries 19.39 Mb of data per second. The eight signal levels are selected with the use of a trellis code.

2001年12月1日 · Since the American Television Systems Committee (ATSC) and the group of “elite” television geniuses that sold this country on eight levels of vestigial side band (8VSB), the American television industry has been trying to turn, what appears to some as a sow’s ear, into a working silk purse.
