Abstract

There is provided a system for imitating distribution and explanation of conference documents in an actual conference so that a conference held in a desktop coferencing system can be made to approximate an actual conference. The system constituted of a transmitting side apparatus and at least one receiving side apparatus includes information management control units for managing the conference documents and information concerning the participants in the conference and controlling the whole system based on the management information, an input unit for inputting the conference documents as data, a transmitting unit and a receiving unit for exchanging data of the conference documents and the management information, a storing unit for storing the data of the conference documents received by the receiving unit, and document display units for displaying the conference documents. In such a system configuration, a conference document displayed in the transmitting side apparatus is transmitted to the receiving side apparatus so that the conference document can be not only stored in the storing unit, but also displayed to the document display unit. Thus, the transmitting side apparatus can distribute any conference document through a network to the receiving side apparatus.

Claims

1. A terminal connected with other terminal through a network, comprising:

management means for managing a common document, using management information relating to the common document;

transmitting means for transmitting the common document managed by said management means through the network to the other terminal; and

supply means for supplying the common document so as to cause the common document to be displayed on a display means,

wherein the common document is constituted with a layered structure, and

wherein one layer in the layered structure of the common document is set so as to be changeable by said terminal.

2. A terminal according to claim 1, wherein said management information includes a file name and page number of the common document.

3. A terminal according to claim 1, wherein said management information includes information concerning said terminal, from which the common document was transmitted.

4. A terminal according to claim 3, wherein the information concerning said terminal includes information for identifying said terminal.

5. A terminal according to claim 1, wherein the document is a document for a conference held through the network, and said transmitting means transmits the common document to one or more other terminals which are participating in the conference.

6. A terminal according to claim 1, further comprising display means.

7. A network conferencing system comprising:

a first terminal, including;

management means for managing a common document,

transmitting means for transmitting the common document managed by said management means through a network, and

supply means for supplying the common document so as to cause the common document to be displayed on a display means of said first terminal; and

a second terminal, including;

receiving means for receiving the common documents transmitted by said transmitting means, and

supply means for supplying the common document received by said receiving means to a display means of said second terminal,

wherein the common document is constituted with a layered structure, and

wherein one layer in the layered structure of the common document is set so as to be changeable by said first terminal.

8. A network conferencing system according to claim 7, wherein said management information incudes a file name and page number of the common document.

9. A network conferencing system according to claim 7, wherein said management information includes information concerning the terminal from which the common document was transmitted.

10. A network conferencing system according to claim 9, wherein the information concerning the terminal from which the common document was transmitted includes information for identifying that terminal.

11. A network conferencing system according to claim 7, wherein the common document is a document for a conference held through the network, said transmitting means transmits the common document to one or more other terminals which are participating in the conference.

12. A network conferencing system according to claim 7, further comprising display means.

13. A control method for plural terminals connected through a network, comprising the steps of:

managing a common document,

wherein the common document is constituted with a layered structure, and

wherein one layer in the layered structure of the common document is set so as to be changeable by said first terminal;

transmitting the common document managed in said managing step through the network to one or more other terminals; and

displaying the common document on a display means.

14. A computer memory storing at least the following processing steps to be executed in a computer:

managing a common document,

wherein the common document is constituted with a layered structure, and

wherein one layer in the layered structure of the common document is set so as to be changeable by said first terminal;

transmitting the common document managed in said managing step through a network to one or more other terminals; and

displaying the common document on a display means.

15. A terminal connected with at least one other terminal through a network, comprising:

management means for managing common pictures which are constituted with a layer structure;

transmitting means for transmitting the common pictures managed by said management means through the network to the at least one other terminal; and

supply means for supplying the common pictures so as to cause the common pictures to be displayed on a display means,

wherein at least one layer in the layered structure of the pictures is set so as to be changeable by a predetermined user.

16. A network conferencing system comprising:

a first terminal, including;

management means for managing common pictures which are constituted with a layer structure;

transmitting means for transmitting the common pictures managed by said management means through the network to the at least one other terminal; and

supply means for supplying the common pictures so as to cause the common pictures to be displayed on a display means,

wherein at least one layer in the layered structure of the pictures is set so as to be changeable by a predetermined user; and

a second terminal, including;

receiving means for receiving the common pictures transmitted by said transmitting means, and

supply means for supplying the common picture received by said receiving means to a display means of said second terminal.
