Abstract

A television receiver apparatus has large versatility to adapt itself to newly offered services or new modes of use. An external memory element loaded with a flash memory is connected to the receiver apparatus through an external memory interface having a connector and an interface circuit. The external memory element stores information such as a program for implementing an additional function or data such as video and audio data. The information stored in the external memory element is taken up by the receiver apparatus through the external memory interface. The information from the external memory element is processed by a controlling portion of the receiver apparatus so as to be subjected to use.
