Abstract

A multiple-contents distribution in a client and server system is disclosed. The multiple-contents contain contents-pieces, which are to be distributed to a set of clients including mobile phone terminals. The set of clients are registered with the server in response to registration requests. The server determines an order of the registered set of clients. The server then initiates a distribution of the contents-pieces to the registered sets of clients, wherein the contents-pieces are selected in accordance with the order of the clients.

Claims

1. A multiple-contents distribution method in a client and server system of distributing multiple-contents containing contents-pieces to a set of clients, the method comprising:

accepting registration requests to register the set of clients with the server;

receiving a request from at least one of the registered set of clients;

distributing the contents-pieces of the multiple-contents to the registered set of clients upon receiving the request, wherein each client receives respective contents-pieces corresponding to each client.

2. A method according to claim 1, further comprising:

determining an order of the registered set of clients; and

selecting the respective contents-pieces in accordance with the determined order.

3. A method according to claim 1, further comprising:

measuring delay times of transmission between the server and each set of clients; and

controlling timings of transmitting the contents-pieces to each set of clients based on the delay times for a simultaneous contents reproduction at the clients.

4. A method according to claim 3, wherein the timings are aligned to that of one client having the longest delay time from the server.

5. A method according to claim 2, further comprising:

generating arrangement-guide contents corresponding to the order of the registered set of clients; and

transmitting the arrangement-guide contents to the registered set of clients in addition to the contents-pieces for guiding how to arrange the clients.

6. A method according to claim 5, wherein the clients arranged in accordance with the arrangement-guide contents form a wide screen and wherein each of the clients displays one of the contents-pieces corresponding to a region of an image.

7. A method according to claim 5, wherein the clients arranged in accordance with the arrangement-guide contents form a multi-screen and wherein each of the clients displays one of the contents-pieces in accordance with a predetermined layout of the multi-screen.

8. A method according to claim 1, wherein the set of clients include cellular phone terminals, and wherein the contents-pieces are transmitted thereto through a data communication other than a telephone communication.

9. A method according to claim 1, further comprising:

transmitting timing information representing timings of reproducing the contents-pieces to the registered set of clients.

10. A server apparatus which distributes multiple-contents containing contents-pieces to a set of clients, the server apparatus comprising:

a storage device which stores the multiple-contents;

an accepting device which accepts registration requests to register the set of clients with the server apparatus;

a receiving device which receives a request from at least one of the registered set of clients;

a contents handler which handles the multiple-contents in the storage device, wherein the contents handler selects the contents-pieces of the multiple-contents; and

a distribution controller which controls a distribution of the multiple-contents, wherein the distribution controller transmits the contents-pieces of the multiple-contents selected by the contents handler to the registered set of clients.

11. A server apparatus according to claim 10, further comprising:

a determining device which determines an order of the registered set of clients, and

wherein the contents handler selects the respective contents-pieces in accordance with the determined order.

12. A server apparatus according to claim 10, further comprising:

a measuring unit which measures delay times of transmission between the server apparatus and each set of clients, and

wherein the distribution controller controls timings of transmitting the contents-pieces to each set of clients based on the delay times for a simultaneous contents reproduction at the clients.

13. A server apparatus according to claim 12, wherein the timings are aligned to that of one client having the longest delay time from the server apparatus.

14. A server apparatus according to claim 11, further comprising:

a contents generator which generates arrangement-guide contents corresponding to the order of the registered set of clients, and

wherein the distribution controller transmits the arrangement-guide contents to the clients in addition to the contents-pieces for guiding how to arrange the clients.

15. A server apparatus according to claim 10, wherein the distribution controller further transmits timing information representing timings of reproducing the contents-pieces to the registered set of clients.

17. A mobile terminal according to claim 16, wherein the contents receiver also receives arrangement-guide contents for guiding how to arrange the mobile terminal among the other mobile terminals.

18. A mobile terminal according to claim 17, wherein the reproduction device forms a part of a wide screen when the mobile terminal is arranged in accordance with the arrangement-guide contents.

19. A mobile terminal according to claim 17, the reproduction device forms a part of a multi-screen when the mobile terminal is arranged in accordance with the arrangement-guide contents.

20. A mobile terminal according to claim 16, wherein the contents receiver is coupled to a data communication link other than a telephone communication link.

21. A mobile terminal according to claim 16, wherein the contents receiver further receives a timing instruction from the server, and wherein the reproduction device reproduces the received one of the contents-pieces in accordance with the timing instruction.

16. A mobile terminal which communicates with a server apparatus distributing multiple-contents containing contents-pieces, the mobile terminal comprising:

a request sender which sends a registration request to the server apparatus in order to share a session with other mobile terminals;

a contents receiver which receives one of the contents-pieces assigned to the mobile terminal from the server apparatus; and

a reproduction device which reproduces the received one of the contents-pieces under the session.

22. A computer program product comprising:

a computer storage medium and a computer program code mechanism embedded in the computer storage medium for causing a computer to distribute multiple-contents containing contents-pieces stored in a storage device to a set of clients, the computer code mechanism comprising;

a first code segment for accepting registration requests to register the set of clients with the computer;

a second code segment for determining relative locations of the registered set of clients to which the contents-pieces are transmitted;

a third code segment for handling the multiple-contents in the storage device, by selecting the contents-pieces in accordance with the relative locations of the set of clients; and

a fourth code segment for distributing the multiple-contents, by transmitting the selected contents-pieces of the multiple-contents to the registered set of clients.

23. A computer program product comprising:

a computer storage medium and a computer program code mechanism embedded in the computer storage medium for causing a computer to communicates with a server apparatus distributing multiple-contents containing contents-pieces, the computer code mechanism comprising;

a first code segment for sending a registration request to the server apparatus in order to share a session with mobile terminals;

a second code segment for receiving one of the contents-pieces assigned to the computer from the server apparatus; and

a third code segment for reproducing the received one of the contents-pieces under the session.
