Abstract:
The receiving apparatus of the present invention includes: a reception unit which receives a broadcast; an output unit which outputs a service included in the received broadcast; an execution unit which executes an application program included in the received broadcast; an extraction unit which extracts, from service information included in the received broadcast, a font identifier which is information for identifying font data corresponding to the service; a switch detection unit which detects that a currently outputted service is switched; a connection unit which adopts, as font data to be used by the application program, font data identified by the font identifier corresponding to the currently outputted service that is detected; and a rendering unit which renders the font data to be used by the application program.
