Abstract

System for transmitting one or more presentation data streams from a presentation workstation. In response to receiving an input to open a presentation application, operating parameters are obtained for a presentation to provide presentation operating parameters for the presentation. One or more selected presentation data streams are captured based on the obtained presentation operating parameters. Then, the one or more captured presentation data streams are transmitted based on the obtained presentation operating parameters directly from the presentation workstation to one or more viewing devices via a network without utilizing an intervening server.

Claims

1. A computer implemented method for transmitting one or more presentation data streams from a presentation workstation, the computer implemented method comprising:

responsive to receiving an input to open a presentation application, obtaining operating parameters for a presentation to provide presentation operating parameters for the presentation;

capturing one or more selected presentation data streams based on the presentation operating parameters for the presentation to form one or more captured presentation data streams; and

transmitting the one or more captured presentation data streams based on the presentation operating parameters for the presentation directly from the presentation workstation to one or more viewing devices via a network without utilizing an intervening server.

2. The computer implemented method of claim 1, further comprising:

recording the one or more captured presentation data streams based on the presentation operating parameters for the presentation to form one or more recorded presentation data streams.

3. The computer implemented method of claim 2, further comprising:

storing the one or more recorded presentation data streams in a presentation file within a storage device in the presentation workstation to provide a complete record of the presentation.

4. The computer implemented method of claim 3, further comprising:

compressing the one or more captured presentation data streams to form one or more compressed presentation data streams, wherein the one or more compressed presentation data streams are transmitted based on the presentation operating parameters for the presentation.

5. The computer implemented method of claim 4, wherein the one or more compressed presentation data streams are recorded based on the presentation operating parameters for the presentation.

6. The computer implemented method of claim 2, wherein the presentation application stops the capturing step for one or more particular presentation data streams when the transmitting and the recording steps for the one or more particular presentation data streams are disabled.

7. The computer implemented method of claim 2, wherein the transmitting and the recording steps may be enabled and disabled independently of each other at the presentation workstation.

8. The computer implemented method of claim 3, wherein one or more of the transmitting, the recording, and the storing steps may be enabled and disabled at the presentation workstation at any time during the presentation based on a user input.

9. The computer implemented method of claim 1, wherein the transmitting step may be enabled and disabled at the presentation workstation for each of the one or more captured presentation data streams independently of other captured presentation data streams.

10. The computer implemented method of claim 1, wherein a selected display content is captured and transmitted, and wherein the selected display content is a current window within a display device in the presentation workstation.

11. The computer implemented method of claim 10, wherein the selected display content is a dynamic animation or video, and wherein the dynamic animation or video is transmitted as a video presentation data stream.

12. The computer implemented method of claim 10, wherein the selected display content is a static image, and wherein the static image is transmitted as an image presentation data stream.

13. The computer implemented method of claim 12, wherein transmission of the image presentation data stream occurs in response to user input or automatically at pre-determined time intervals at the presentation workstation.

14. The computer implemented method of claim 2, further comprising:

inserting navigation tags into the one or more captured presentation data streams at the presentation workstation.

15. The computer implemented method of claim 14, wherein a user inserts the navigation tags into the one or more captured presentation data streams at the presentation workstation.

16. The computer implemented method of claim 1, wherein the presentation application automatically inserts navigation tags into the one or more captured presentation data streams at the presentation workstation.

17. The computer implemented method of claim 1, wherein the presentation application sends a presentation address identifier to the one or more viewing devices via the network for a run-time execution environment on the one or more viewing devices to access the captured presentation data streams.

18. The computer implemented method of claim 17, further comprising:

downloading a player application from the presentation workstation to the one or more viewing devices via the network using the presentation address identifier.

19. The computer implemented method of claim 17, wherein the one or more viewing devices connect to the presentation workstation and initiate transmission of the one or more captured presentation data streams using the presentation address identifier.

20. The computer implemented method of claim 17, wherein the run-time execution environment is a Web browser, and wherein the presentation address identifier is a uniform resource locator.

21. The computer implemented method of claim 2, wherein users of the one or more viewing devices select which transmitted or recorded one or more captured presentation data streams to output on the one or more viewing devices.

22. The computer implemented method of claim 14, wherein users of the one or more viewing devices utilize the navigation tags in the one or more captured presentation data streams to navigate through the presentation at the one or more viewing devices.

23. A data processing system for transmitting one or more presentation data streams, comprising:

a bus system;

a storage device connected to the bus system, wherein the storage device includes a set of instructions; and

a processing unit connected to the bus system, wherein the processing unit executes the set of instructions to obtain operating parameters for a presentation to provide presentation operating parameters for the presentation in response to receiving an input to open a presentation application, capture one or more selected presentation data streams based on the presentation operating parameters for the presentation to form one or more captured presentation data streams, and transmit the one or more captured presentation data streams based on the presentation operating parameters for the presentation directly from a presentation workstation to one or more viewing devices via a network without utilizing an intervening server.

24. The data processing system of claim 23, wherein the processing unit executes a further set of instructions to record the one or more captured presentation data streams based on the presentation operating parameters for the presentation to form one or more recorded presentation data streams.

25. The data processing system of claim 24, wherein the processing unit executes a further set of instructions to store the one or more recorded presentation data streams in a presentation file within a storage device in the presentation workstation to provide a complete record of the presentation.

26. A computer program product for transmitting one or more presentation data streams from a presentation workstation, the computer program product comprising:

a computer usable medium having computer usable program code embodied therein, the computer usable medium comprising;

computer usable program code configured to obtain operating parameters for a presentation to provide presentation operating parameters for the presentation in response to receiving an input to open a presentation application;

computer usable program code configured to capture one or more selected presentation data streams based on the presentation operating parameters for the presentation to form one or more captured presentation data streams; and

computer usable program code configured to transmit the one or more captured presentation data streams based on the presentation operating parameters for the presentation directly from the presentation workstation to one or more viewing devices via a network without utilizing an intervening server.
