FILM-TO-VIDEO FORMAT DETECTION FOR DIGITAL TELEVISION |
摘要 |
<p>19 FILM-TO-VIDEO FORMAT DETECTION FOR DIGITAL TELEVISION A film-to-video format detector (24) for a digital television receiver (10). The detector (24) receives pixel data from a current field and a second preceding field. It determines a set of pixel difference values, sums them to obtain a field difference value, and compares the field difference value to a threshold. These steps are repeated to obtain a series of field difference indicators. This series is analyzed to determine whether it has a pattern corresponding to a film-to-video format.</p> |
