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.
