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

摘要

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