Receiving apparatus, receiving method, receiving program, recording medium with the program recorded therein and communication system

A receiving apparatus comprising:

• a receiving section for receiving a first broadcast, a second broadcast, and a third broadcast each broadcasting first information in a different frequency band respectively, and also receiving a fourth broadcast, a fifth broadcast, and a sixth broadcast each broadcasting second information with the contents different from those of said first information in a different frequency band respectively;
• a first demodulating section for demodulating said first and fourth broadcasts;
• a second demodulating section for demodulating said second and fifth broadcasts;
• and
• a third demodulating section for demodulating said third and sixth broadcasts, wherein said first demodulating section, second demodulating section, and third demodulating section execute demodulation simultaneously, said third demodulating section demodulates said sixth broadcasts when said second demodulating section demodulates said second broadcast, and said third demodulating section demodulates said third broadcast when said second demodulating section demodulates said fifth broadcast.

• and
• a third demodulating section for demodulating said fifth and sixth broadcasts, wherein said first demodulating section, second demodulating section, and third demodulating section execute demodulation simultaneously.

A receiving method of receiving a plurality of groups of information each group including a plurality of different information, said plurality of groups transmitted as electric waves in different frequency bands from an earth station and a plurality of artificial satellites respectively, fetching a specified group of information by demodulating the received electric wave, and fetching the information included in the group of information, said method comprising the steps of:

• fetching any one of said plurality of groups of information by demodulating, of the electric waves received from said earth station, the electric wave in any one frequency band;
• fetching, by demodulating the electric waves received from at least any one of said plurality of artificial satellites in a frequency band corresponding to the same group of information as that fetched based on the electric wave received from said earth station, said same group of information;
• and
• fetching said other groups of information by modulating, of the electric waves received from at least any one of said artificial satellites, those in the frequency band corresponding to the groups of information other than that fetched based on the electric wave received from said earth station.
