Abstract
An image reproduction system includes a data bus for transmitting a compressed and coded digital image signal, in which compression mode information related to the compressing and coding of the digital image signal is added to the digital image signal. The system also includes a first input device that inputs the digital image signal transmitted by the data bus and a second input device that inputs an analog image signal. A converter converts the analog image signal inputted by the second input device to a digital signal. A buffer memory selectively stores either the digital image signal inputted by the first input device or the digital signal converted by the converter.
