<p>A decoder for MPEG and the like, in which a voice can be outputted even if an image is frozen and the voice can be synchronized with the voice immediately after the image is unfrozen. A dynamic image data is frozen and outputted continuously by using the third output buffer region (8D) of a memory (8), and the I picture and P picture in a dynamic image data stream being inputted during freeze are decoded by using the first ouput buffer region (8B) and the second output buffer region (8C). A voice data stream is decoded while being kept in synchronism with the dynamic image. Since decoded I picture and P picture are stored in the first output buffer region (8B) and the second output buffer region (8C) even during freeze, the image data synchronized with the voice data can be outputted immediately after it is unfrozen.</p> |
