DECODING DEVICE AND DISPLAY SYSTEM FOR VIDEO SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide the video signal decoding device which enables a high- picture-quality display free of interlacing disturbance on an LCD monitor and the display system which uses the video signal decoding device. SOLUTION: A frame/field process deciding means 302 decides whether data decoded by a variable-length decoding part 301 has frames processed or fields processes by macroblocks. When the data have the fields processed, it is judged that the data is an area having movement in a frame and a field interpolating means 307 generates frame data by interpolation and outputs the data.
