DIGITAL BROADCAST RECEPTION SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, SIGNAL PROCESSING PROGRAM, AND DIGITAL BROADCAST RECEIVER

摘要

A signal processing device for creating as natural a display video as possible with as high a quality as possible from the received signal of digital broadcast provided by simulcast. The signal processing device comprises a first decoder for performing motion compensation prediction by analyzing a first coded bit stream, acquiring a syntax element, and using the syntax element for the motion compensation prediction, a second decoder for performing motion compensation prediction by analyzing a second coded bit stream, acquiring a syntax element, and using the syntax element for the motion compensation prediction, and a syntax element converting section for converting the syntax element acquired by the second decoder into a syntax element adapted to the image format of the first coded bit stream. In response to detection of an error the first decoder performs motion compensation prediction by using the syntax element acquired by the conversion by the syntax element converting section in place of the syntax element acquired by the first decoder.
