Device and method for converting aspect ratio of video signal

A device for converting an aspect ratio of a video signal, the device displaying a received image on a screen divided into a plurality of horizontal sections and vertical sections, the device comprising:

• a micro-processor for generating interpolation ratio conversion extent information in block units defined by the horizontal and vertical sections;
• a bus decoder for receiving, decoding and storing the interpolation ratio conversion extent information;
• and,
• an interpolation ratio controller for using the stored interpolation ratio conversion extent information in determining horizontal and/or vertical interpolation ratio conversion extents for each block and making different conversion of an interpolation ratio for each horizontal and/or vertical positions of the received image according to the extents.
