Abstract

A system, method, and article of manufacture that allow a document containing custom objects to be shared in a distributed collaborative computer system. This is accomplished by allowing custom objects to be embedded in a document. When the document is to be shared, the document with custom objects is converted to a Rich Multi-Media (RMM) format. Furthermore, the converted document may be shared during a collaborative session among multiple computers. Alternatively, the converted document may be viewed by a user independent of a collaborative session.

Claims

1. A computer system for sharing a document in a distributed collaborative environment:

a presenter client computer;

one or more computer programs executable by the presenter client computer,

wherein the one or more computer programs comprise computer instructions for;

creating a document with one or more embedded custom objects, wherein the embedded custom objects include a video object;

converting the document to a rich multi-media format; and

controlling rendering of the document during a collaborative session;

a conferencing server computer connected to the presenter client computer and to one or more attendee client computers via a global-area network; and

a computer program at the conferencing server computer,

wherein the computer program comprises instructions for;

receiving the document and forwarding the document to each of the attendee client computers to be downloaded onto each of the attendee client computers before the collaborative session;

receiving a remote command for sharing the document from the presenter client computer during the collaborative session; and

forwarding the remote command to each of the attendee client computers, wherein each of the attendee client computers renders its locally downloaded document according to the received remote command such that playback of the video object embedded in the locally downloaded document at each of the attendee client computers is remotely controlled by the remote command to be in synch with the presenter computer.

2. The computer system of claim 1, further comprising:

a computer program executable by each attendee client computer, wherein the computer program comprises computer instructions for;

receiving a command from the conferencing server computer; and

executing the command to render the document in synch with the presenter client computer.

3. The computer system of claim 2, further comprising:

a streaming server computer connected to the presenter client computer and the one or more attendee client computers via a global-area network for storing data to be accessed by the client computers during a collaborative session.

4. The computer system of claim 1, wherein the custom objects embedded in the document downloaded to each of the attendee client computers before the collaborative session include a media object, and each of the attendee client computers plays the media object embedded in its locally downloaded document according to another remote command from the presenter computer such that playback of the media object at each of the attendee client computers is in synch with the presenter computer.

5. The computer system of claim 4, wherein the embedded media object is selected from the group consisting of a video object, an audio object, a 3D model and a meeting recording object.

6. The computer system of claim 1, wherein each attendee computer comprises a local viewer program that is remotely controlled by the remote command from the presenter computer to play the video object embedded in the locally downloaded document in sync with the presenter computer.

7. A method for sharing a document between a first computer and one or more additional attendee computers, the method comprising:

creating a document with one or more embedded custom objects at the first computer, wherein the embedded custom object include a video object;

converting the document to a rich multi-media format;

downloading the document onto the one or more additional attendee computers before a collaborative session; and

remotely controlling rendering of the locally downloaded document at each of the attendee computers from the first computer during the collaborative session such that playback of the video object embedded in the locally downloaded document at each of the attendee computers is remotely controlled by the first computer to be in synch with the first computer.

8. The method of claim 7, wherein controlling rendering further comprises:

under control of the a first computer, transmitting a command for sharing the document to a second computer for transmission to the one or more additional attendee computers, such that the command is executed synchronously at the first computer and each of the one or more additional attendee computers.

9. The method of claim 8, further comprising:

under control of each of the one or more additional attendee computers, receiving the command from the second computer; and

executing the command to render the document in synch with the first computer.

10. The method of claim 9, further comprising:

accessing a streaming server computer for data required to render the document.

11. A computer-readable storage medium storing a computer program executable by a first computer for sharing a document between the first computer and one or more additional attendee computers, the computer program comprising computer instructions for:

creating a document with one or more embedded custom objects at the first computer, wherein the embedded custom object include a video object;

converting the document to a rich multi-media format;

downloading the document onto the one or more additional attendee computers before a collaborative session; and

remotely controlling rendering of the locally downloaded document at each of the attendee computers from the first computer during the collaborative session such that playback of the video object embedded in the locally downloaded document at each of the attendee computers is remotely controlled by the first computer to be in synch with the first computer.

12. The computer-readable storage medium of claim 11, wherein the computer program further comprises computer instructions for:

transmitting a command for sharing the document from the first computer to a second computer for transmission to the one or more additional attendee computers, such that the command is executed synchronously at the first computer and each of the one or more additional attendee computers.

13. The computer-readable storage medium of claim 11, wherein the computer program further comprises computer instructions for:

accessing a streaming server computer for data required to render the document.
