In a display apparatus, a text code input section outputs externally-supplied text code information to a font conversion section and a voice synthesizer section. The font conversion section converts the input text code into a corresponding font, and transmits the font to a display drive section via a video signal input section, and the display drive section causes a display section to display the font. Meanwhile, the voice synthesizer section converts the input text code into corresponding voice data, and transmits the voice data to a voice device where the voice data is outputted. With this structure, superior convenience is ensured for a display apparatus which serves only as an individual displaying apparatus and relies on an external device (server) for the major functions of the system.
