Abstract

A receiving system of the present disclosure includes: a plurality of demodulators; an add-on generating one stream based on an output from each of the demodulators; a selector selecting and outputting one among an output from one of the demodulators, namely the demodulator, and the one stream from the add-on; and a back-end processor generating an output for a display based on an output from the selector and the other demodulators, namely the demodulators. The selector selects an output from the demodulator in a single channel transmission mode, and selects the stream from the add-on in a multiple channel transmission mode.

First claim

What is claimed is:

1. A receiving system receiving a plurality of carriers and generating one or a plurality of streams, the system comprising:
a first demodulator receiving and processing a first transmission signal;
a second demodulator receiving and processing a second transmission signal different from the first transmission signal;
a combiner generating one stream based on at least an output of the first demodulator and an output of the second demodulator;
a selector receiving an output from the first demodulator and the one stream from the combiner as inputs, and selecting and outputting one among the output from the first demodulator and the one stream from the combiner; and
a back-end processor receiving an output from the selector and an output from the second demodulator as inputs, and generating an output for a display, wherein
the selector selects the output from the first demodulator in a receiving mode in single channel transmission, and selects the one stream in a receiving mode in multiple channel transmission.

2. The receiving system of claim 1 , wherein the first demodulator, the second demodulator, the combiner, the selector, and the back-end processor are implemented with one LSI.

3. The receiving system of claim 1 , wherein the combiner, the selector, and the back-end processor are implemented with one LSI.

4. The receiving system of claim 1 , wherein the combiner and the selector are implemented with one LSI.

5. The receiving system of claim 1 , wherein the back-end processor processes an output from the selector and the output from the second demodulator separately in the receiving mode in single channel transmission, and processes the output from the selector while not processing the output from the second demodulator in the receiving mode in multiple channel transmission.

6. The receiving system of claim 1 , wherein the back-end processor determines whether the receiving mode in single channel transmission or the receiving mode in multiple channel transmission is selected.

7. A receiving system receiving a plurality of carriers and generating one stream, the system comprising:
a first demodulator receiving and processing a first transmission signal;
a second demodulator receiving and processing a second transmission signal different from the first transmission signal; and
a combiner generating one stream based on at least an output from the first demodulator and an output from the second demodulator, wherein
in the combiner, rearrangement and combination of data output by the first demodulator and of data output by the second demodulator are performed based on header information obtained from the first and second demodulators, and first identification data and second identification data which are respectively bound to target data to be rearranged,
the second identification data indicate order of arrangement in a group of data, of the first identification data, having an identical value, and
the header information includes information for specifying each carrier of the plurality of carriers.

8. The receiving system of claim 7 , wherein the rearrangement and combination is performed based on the first identification data, the second identification data and a predetermined data corresponding to the second identification data which are defined as information inside an updateable storage in the combiner.

9. The receiving system of claim 7 , wherein
the stream comprises a plurality of packets in which indices indicating continuity of data in the packets are present,
the second identification data are the indices indicating the continuity of data.

10. A receiving system receiving a plurality of carriers and generating one stream, the system comprising:
a first demodulator receiving and processing a first transmission signal;
a second demodulator receiving and processing a second transmission signal different from the first transmission signal; and
a combiner generating one stream based on at least an output from the first demodulator and an output from the second demodulator, wherein
in the combiner, rearrangement and combination of data output by the first demodulator and of data output by the second demodulator are performed based on header information obtained from the first and second demodulators, and
the header information includes information for specifying each carrier of the plurality of carriers.

11. The receiving system of claim 10 , wherein the information for identifying the plurality of carriers is 8-bit information.

12. The receiving system of claim 11 , wherein the 8-bit information is included in header information of an extension.

13. A receiving system according to claim 10 , wherein the first demodulator and the second demodulator perform different demodulation techniques, and each of the first demodulator and the second demodulator receives a signal in a different modulation, and demodulates the signal.

14. A receiving system according to claim 7 , wherein the first demodulator and the second demodulator perform different demodulation techniques, and each of the first demodulator and the second demodulator receives a signal in a different modulation, and demodulates the signal.
