Abstract

A digital decoder decodes a digital broadcast signal inputted, and outputs a plurality of caption service data CSD1 to CSD6 to a CPU. The CPU 1 selects two among the CSD1 to CSD6, and converts the selected caption service data into closed caption data. The two closed caption data are allocated to each of closed captions CC1 and CC3, and are outputted from a digital broadcast/analog broadcast receiving apparatus to a display device.
