  • HDTV up converter
    Patent number: 6181382
    Abstract: An electronic apparatus for converting a standard video signal having 59.94 fields per second into an HDTV video signal having 60.00 fields per second, by adding a number of video fields into each sequence of 1000 video fields. The apparatus detects the best moment for adding the new video field, so that the human eye does not perceive an abrupt change in the video image, by detecting the best motion conditions which occurs either when the image motion is high or very low. For adding the new video field, the apparatus uses an interpolation technique for creating two interpolated video fields which are inserted in place of one existing video field which is deleted. The apparatus also comprises a de-interlacer module for deinterlacing the 60 Hz video image, by using an advanced interpolation technique for calculating the missing video lines.
