Abstract

An Internet system includes an original server that transmits its contents to a platform server. The platform server collects the contents, and broadcasts them to receivers through satellite channels via a communications satellite. When the contents transmitted from a satellite Internet subnetwork includes contents requested by user terminals, the receivers select the desired contents, and deliver them to the user terminals. When the contents do not include the desired contents, the receivers receive them from a CATV Internet subnetwork or a terrestrial Internet subnetwork, and delivers them. Thus, the Internet system can selects the channels in response to the traffic of the channels or to the desired contents.

Claims

1. An Internet system comprising:

a receiver for receiving contents like image information from a first Internet subnetwork using a radio channel with a broadcasting function;

for selecting, when contents requested by a user terminal are included in the contents transmitted from said first Internet subnetwork, the contents requested by said user terminal from among the contents transmitted from said first Internet subnetwork; and

for delivering the contents requested by said user terminal to said user terminal.

2. The Internet system according to claim 1, wherein when the contents requested by said user terminal are not included in the contents transmitted from said first Internet subnetwork, said receiver changes its connection to a second Internet subnetwork using wired channels, and delivers the contents requested by said user terminal to said user terminal by receiving them from said second Internet subnetwork.

3. The Internet system according to claim 1, wherein said receiver stores the contents received from said first Internet subnetwork into a storage, and delivers the contents requested by said user terminal to said user terminal by retrieving them from said storage.

4. The Internet system according to claim 1, wherein said receiver stores index information including titles and contents of the contents transmitted from said first Internet subnetwork into a storage.

5. The Internet system according to claim 1, wherein said first Internet subnetwork consists of a satellite network using a communications satellite and satellite channels.

12. The Internet system according to claim 2, wherein said second Internet subnetwork consists of at least one of a cable television Internet subnetwork and a terrestrial Internet subnetwork based on dialup Internet protocol connection and leased line Internet protocol connection.

6. An Internet system comprising an original server that possesses contents like image information, that monitors an access state from a second Internet subnetwork using a wired channel, and that when said second Internet subnetwork is likely to congest, transmits contents that have been transmitted through said second Internet subnetwork via a first Internet subnetwork using a radio channel with a broadcasting function.

7. The Internet system according to claim 6, further comprising a receiver for receiving the contents from said first Internet subnetwork and from said second Internet subnetwork that is likely to congest;

for changing its connection to said first Internet subnetwork when contents requested by a user terminal are included in the contents transmitted from said first Internet subnetwork;

for selecting the contents requested by said user terminal from the contents transmitted from said first Internet subnetwork; and

for delivering the contents selected to said user terminal.

9. The Internet system according to claim 6, wherein said first Internet subnetwork consists of a-satellite network using a communications satellite and satellite channels.

13. The Internet system according to claim 6, wherein said second Internet subnetwork consists of at least one of a cable television Internet subnetwork and a terrestrial Internet subnetwork based on dialup Internet protocol connection and leased line Internet protocol connection.

8. An Internet system comprising a platform server that is connected via a network to a plurality of original servers each possessing contents like image information;

and that when a second Internet subnetwork using a wired channel is likely to congest, transmits the contents, which have been transmitted by each original server via said second Internet subnetwork, via a first Internet subnetwork using a radio channel with a broadcasting function in response to a request from said original server.

10. The Internet system according to claim 8, wherein said first Internet subnetwork consists of a satellite network using a communications satellite and satellite channels.

11. The Internet system according to claim 10, wherein said communications satellite and satellite channels employ Ka band of 30 GHz/20 GHz band.

14. The Internet system according to claim 8, wherein said second Internet subnetwork consists of at least one of a cable television Internet subnetwork and a terrestrial Internet subnetwork based on dialup Internet protocol connection and leased line Internet protocol connection.
