摘要：
A method and system for detecting a VSB mode in a digital TV receiver is disclosed. The system includes first and second VSB mode detectors implemented before and after a channel equalizer. The first VSB mode detector detects a VSB mode from a signal before channel-equalization, the second VSB mode detector detects a VSB mode from a channel-equalized signal, and one of the detected VSB modes is output to the channel equalizer as the finally detected VSB mode.
