ENCODING/DECODING APPARATUS PROVIDED WITH INPUT/OUTPUT INTERFACE FOR EXTERNAL EQUIPMENT

摘要

The present invention aims that an external equipment can easily utilize a writing/reading part (1) such as a CD-ROM driver, a decoding processing part (2) and a display part (3) inside an encoding/decoding apparatus built in a television receiver without deteriorating previous decoding function. A signal switcher (6) and an input/output interface (5) for an external equipment (7) are provided with in a encoding/decoding apparatus. A display part (3) in the encoding/decoding apparatus can be utilized by controlling a signal switcher (6) to select either a signal from a writing/reading part (1) or an external signal from the input/output interface for an external equipment (702) by a control microcomputer (701) and supplying the output of the signal switcher to a display part through a decoding processing part (201).
