  • System and methods for both 2-tap and 3-tap flicker filtering of non-interlaced computer graphics to interlaced lines for television display
    Patent number: 6084568
    Abstract: A device performs both 2-tap and 3-tap flicker filtering of non-interlaced lines of computer graphics data to form interlaced lines. The device includes a data packer, a data unpacker, and a filter circuit. The filter circuit combines lines that it receives to form filtered lines. The data packer writes the filtered lines to line buffers while the data unpacker reads the lines stored in the line buffers. The read lines are either sent to the filter circuit for further filtering or are outputted to be displayed as interlaced lines. Both 2-tap and 3-tap flicker filtering can be accomplished by varying the order and/or number of read, write, and filter operations.
