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 content distribution method, comprising:

accepting registration requests to register a set of clients with a server, where the set of clients includes two or more clients;

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

distributing a set of contents-pieces to the registered set of clients upon receiving the request,

determining an order of the registered set of clients;

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

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;

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

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

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

wherein each client receives respective contents-pieces corresponding to each client, the set of contents-pieces being a meaningful content,

wherein the meaningful content is jointly formed by the set of contents-pieces when the set of clients reproduce the set of contents-pieces in a reproduction session,

wherein the timings are aligned to that of one client having the longest delay time from the server,

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.

2. A method according to claim 1, 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.

3. A method according to claim 1, 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.

4. A server apparatus which distributes multiple-contents containing contents-pieces to a set of clients, where the set of the clients includes two or more 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;

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;

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

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

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

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

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,

wherein the timings are aligned to that of one client having the longest delay time from the server apparatus,

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, and

wherein the distribution controller further transmits timing information representing timings of reproducing the contents-pieces to the registered set of clients.

5. A mobile terminal which communicates with a server apparatus distributing a set of contents-pieces, the set of contents-pieces being a meaningful content, 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 set of contents-pieces assigned to the mobile terminal from the server apparatus; and

a reproduction device which reproduces the received one of the set of contents-pieces in a reproduction session

wherein the meaningful content is jointly formed by the set of contents-pieces when a plurality of mobile terminals reproduce the set of contents-pieces in the session

wherein the contents receiver also receives arrangement-guide contents for guiding how to arranged the mobile terminal among the other mobile terminals,

wherein the reproduction device forms a part of a wide screen when the mobile terminal is arranged in accordance with the arrangement-guide contents,

wherein the reproduction device forms a part of a multi-screen when the mobile terminal is arranged in accordance with the arrangement-guide contents,

wherein the contents receiver is coupled to a data communication link other than a telephone communication link
