Abstract

A technique enabling several kinds of contents information to be used in terminals like cellular phones, regardless of the type of terminals without burdening contents providers. A contents conversion server receives, from a terminal, access destination information such as a URL of a contents providing server, and type information on the terminal or on its browser. Next, if the access destination information is interpreted to point to contents information not in the contents conversion server, but in the contents providing server, as an access destination, the contents conversion server obtains the pointed to contents information from the contents providing server. Then, the contents conversion server converts an arbitrary type of obtained contents information, based on the type of information, and moreover, converts the link information, if included, in accordance with a predetermined rule. Consequently, the contents conversion server sends converted contents information to the terminal.

Claims

1. A contents conversion method in a contents conversion server, which is connected to a plurality of user terminals and a plurality of contents providing servers through a network, comprising:

receiving, from a certain user terminal of said plurality of user terminals, access destination information and information concerning a type of said certain user terminal or an access requesting source in said certain user terminal;

if said access destination information is interpreted to represent only said contents conversion server as an access destination, transmitting, to said certain user terminal, information including link information causing access via said contents conversion server to a contents providing server registered in said contents conversion server in advance; and

if said access destination information is interpreted to represent contents information in one of said plurality of said contents providing servers as an access destination, performing a conversion processing, and

wherein performing said conversion processing comprises;

acquiring contents information represented in said access destination information from said one of plurality of said contents providing servers;

by converting said contents information of an arbitrary format, based on said information concerning said type of said certain user terminal or said access requesting source in said certain user terminal, and by further converting link information included in said contents information in accordance with a predetermined rule to convert an original link destination into a format in which said contents conversion server is set as an access destination and information concerning said original link destination is included, generating converted contents information; and

transmitting the converted contents information to said certain user terminal.

2. The contents conversion method as set forth in claim 1, further comprising:

if said access destination information is interpreted to represent only said contents conversion server as an access destination and a search condition for the registered contents providing servers is received, searching said registered contents providing servers matching with said search condition and transmitting, to said certain user terminal, information including link information causing access via said contents conversion server to said registered contents providing servers matching with said search condition.

3. A program embodied on a computer-readable medium causing a contents conversion server, which is connected to a plurality of user terminals and a plurality of contents providing servers through a network, to convert contents, said program comprising:

receiving from a certain user terminal of said plurality of user terminals, access destination information and information concerning a type of said certain user terminal or an access requesting source in said certain user terminal;

if said access destination information is interpreted to represent only said contents conversion server as an access destination, transmitting, to said certain user terminal, information including link information causing access via said contents conversion server to a contents providing server registered in said contents conversion server in advance; and

if said access destination information is interpreted to represent contents information in one of said plurality of said contents providing servers as an access destination, performing a conversion processing, and

wherein said performing said conversion processing comprises;

acquiring contents information represented in said access destination information from said one of the plurality of said contents providing servers;

by converting said contents information of an arbitrary format, based on said information concerning said type of said certain user terminal or said access requesting source in said certain user terminal, and by further converting link information included in said contents information in accordance with a predetermined rule to convert an original link destination into a format in which said contents conversion server is set as an access destination and information concerning said original link destination is included, generating converted contents information; and

transmitting the converted contents information to said certain user terminal.

4. The program as set forth in claim 3, further comprising:

if said access destination information is interpreted to represent only said contents conversion server as an access destination and a search condition for the registered contents providing servers is received, searching said registered contents providing servers matching with said search condition, and transmitting, to said certain user terminal, information including link information causing access via said contents conversion server to said registered contents providing servers matching with said search condition.

5. A contents conversion server, which communicates with a plurality of user terminals and a plurality of contents providing servers through a network, comprising:

a unit that receives from a certain user terminal of said plurality of user terminals, access destination information and information concerning a type of said certain user terminal or an access requesting source in said certain user terminal, the unit responsive to access destination information interpreted to represent only said contents conversion server as an access destination, transmitting, to said certain user terminal, information including link information causing access via said contents conversion server to a contents providing server registered in said contents conversion server in advance;

a unit that acquires contents information represented in said access destination information from one of said plurality of said contents providing servers as an access destination, if said access destination information is interpreted to represent contents information in said one of the plurality of said contents providing servers;

a converter that converts said contents information of an arbitrary format, based on said information concerning said type of said certain user terminal or said access requesting source in said certain user terminal, and further converting link information included in said contents information in accordance with a predetermined rule to convert an original link destination into a format in which said contents conversion server is set as an access destination and information concerning said original link destination is included, to generate converted contents information; and

a unit that transmits the converted contents information to said certain user terminal.

6. The contents conversion server as set forth in claim 5, further comprising:

a unit that searches registered contents providing servers matching with a search condition if said access destination information is interpreted to represent only said contents conversion server as an access destination and said search condition for the registered contents providing servers is received; and

a unit that transmits information including link information causing access via said contents conversion server to said registered contents providing servers matching with said search condition.
