<p>The present invention excludes the deterioration in image quality due to errors by concealment processing for decoded image data, thereby to improve the image quality of decoded images, without causing high deterioration in image quality resulting from the concealment processing. The moving picture decoding apparatus of the present invention has a decoder 1 for decoding an input stream for each macroblock and generating decoded image data, a transmission error detector 3 for detecting a transmission error in the input stream, and a stream error detector 6 for detecting a stream error in the input stream. When the transmission error is detected, the moving picture decoding apparatus conceals the decoded image data in macroblock units and when the stream error is detected, the moving picture decoding apparatus conceals the decoded image data in video packet units. <IMAGE></p> |
