Signal processing system using external storage device

摘要

A signal processing system comprises a signal processing device which includes a connector and a plurality of kinds of external storage devices which are arranged to store respective different kinds of information signals. In this system, the plurality of kinds of external storage devices are selectively connectable to the signal processing device through the connector, the information signal is transmissible to the signal processing device through the connector from the external storage device connected to the signal processing device, and the signal processing device further includes a detecting circuit which is arranged to detect via the connector the kind of the external storage device connected to the signal processing device. The system thus allows the external storage devices having information of varied kinds to be connected through one and the same connector. Therefore, information of diverse kinds can be formed and processed without necessitating any complex system arrangement.
