Data receiving apparatus and method in a VBI receiver |
摘要 |
A VBI receiver and method is disclosed. The receiver includes an over-sampling circuit, a transition detector, a data selector, and a data output device. The over-sampling circuit is for over-sampling VBI data and outputting and over-sampled signal. The transition detector is for detecting the transition of the over-sampled signal and outputting a transition signal representing the transition position. The data selector is for recording the transition signal and outputting a position signal according to the transition signal and at least a previous transition signal. The data output device outputs digital output data from the over-sampled signal according to the position signal.
