ABSTRACT:
A video processing apparatus including a display comprises a filter for receiving a video signal containing video information and ancillary information related to the video information and having a predetermined frequency. The filter passes a component corresponding to the frequency of the video signal. An ancillary information extractor extracts the ancillary information from the video signal passed by the filter. A video processor processes the video signal so that the ancillary information extracted by the ancillary information extractor is displayed on the display. The video processing apparatus is able to enhance the reliability of ancillary information extraction by removing the influence of noise.
