In order to accurately display the information on the format of a signal source apparatus and a signal by image, the output signals of analog signal sources are supplied through interface, signal lines and interfaces to analog signal processing circuit. Also, output signals of digital signal sources and output signals of information generating circuits are synthesized by multiplexers and supplied to a demultiplexer through interfaces, buses and an interface. The signals from the separated sources are processed in a digital signal processing circuit. The signals from the separated generating circuits are supplied to an information processing circuit, so that an image corresponding to the information indicating the format of the apparatus and/or the output signal is formed, and is synthesized with the signals from the signal processing circuits to be supplied to a monitor. <IMAGE> |
