A digital broadcast data receiving apparatus comprises a plurality of broadcast data receiving units for receiving digital broadcast data supplied from a plurality of digital broadcast data sources, respectively and a parallel receiving unit for receiving, from the digital broadcast data output from the plural broadcast data receiving units, object program broadcast data which are multiplexed digital broadcast data including program broadcast data relating to an object program broadcast to be viewed by the viewer, and received broadcast data which are digital broadcast data output from the broadcast data receiving unit different from the broadcast data receiving unit which outputs the object program broadcast data. The parallel receiving unit performs the following processes according to time division multiplexing: a process of extracting program broadcast data relating to the object program broadcast to be viewed from the object program broadcast data, and a process of extracting data including information to be obtained even when the viewer does not watch the broadcast, from the received broadcast data. Therefore, it is possible to realize a receiving apparatus Which receives digital broadcast data supplied from plural input sources at the same time, and obtains necessary data included in the digital broadcast data supplied from one of the input sources while displaying the digital broadcast data supplied from the other input source, on a television receiver.
