ABSTRACT:
Disclosed is an apparatus and method for image conversion and automatic error correction for a digital television receiver (TV) which can improve the picture quality by converting an image signal for a TV or PC that displays an image having an RGB format into an image signal of YPbPr for the digital TV and automatically correcting an error produced in the received image signal. The apparatus includes an image receiving and converting section for converting an image receiving and converting section for converting received RGB image data into image data of a digital TV format and rearranging parity bits and error information bits produced from the converted image data to form one image signal, a storage and image providing section for receiving the image signal from the image receiving and converting section, storing the image signal in a memory bank and providing the image signal so as to detect and correct an error produced in the image signal, and an error correcting and outputting section for receiving the image signal from the storage and image providing section, correcting the error by computing the parity bits and the error information bits from the original image data of the image signal, and interpolating the image to match a 16:9 aspect ratio for the digital TV.
