5. The image forming apparatus according to claim 4, wherein the coupling members are constant-velocity joints.
6. The image forming apparatus according to claim 1, wherein the drive unit further comprises a timing belt to transmit the drive force generated by the drive force generator to the drive shaft.
7. The image forming apparatus according to claim 1, wherein the bracket is formed of resin.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A method for creating an interactive video program comprising:
creating an episode file with a number of content assets, each asset including one or more of text, graphics, video, and functionality; and
associating each content asset with a location in a script andor pre-finalized video stream.
2. The method of claim 1 further comprising, when the video stream is finalized, associating the content assets with a time code in the video stream.
3. The method of claim 1, wherein at least some of the content assets are associated with the video stream at the time the script is created using a script writing tool andor an interactive content tool.
4. The method of claim 1, wherein at least some or all of the content assets are associated with the video stream at the time the video stream is edited using video editing post-production equipment andor an interactive content tool.
5. The method of claim 1, wherein at least some of the content assets are associated with the video stream after the video stream is edited using video editing post- production equipment andor an interactive content tool.
6. The method of claim 1, wherein additional content assets are associated with the video stream after editing.
7. The method of claim 1, wherein the video stream is part of a television program, and the interactive content is created during multiple points in the television production process for use by participants on multiple interactive television systems and using various user hardware devices and software.
8. The method of claim 7, wherein each content asset is used to describe the content, presentation, and behavior of an interactive application.
9. The method of claim 8, wherein a description of the content can be an object displayed as a combination of one or more of text, pictures, sounds, and video.
10. The method of claim 8, wherein the description of the presentation includes location on the screen, text styles, and background colors.
11. The method of claim 8, wherein the behavior description includes what actions happen initially and what happens in reaction to a particular user action andor lack of action.
12. The method of claim 7, wherein XML is used to describe at least of the following components of an interactive television application: content, presentation, and behavior.
13. The method of claim 12, wherein the description of the content can be an object displayed as a combination of one or more of text, pictures, sounds, and video.
14. The method of claim 12, wherein the description of the presentation includes location on the screen, text styles, and background colors.
15. The method of claim 12, wherein the behavior description includes what actions happen initially and what happens in reaction to the particular user action or lack of action.
16. The method of claim 1, further comprising providing to remote user hardware devices the content assets to allow a user to view and respond to the interactive content in the episode file.
17. A content production system including an interface, responsive to inputs from one or more of script writing software, non-linear editing software, and direct user inputs, and storage for storing content, presentation, and behavior information using an XML schema.
18. The content production system of claim 17, wherein the interface is responsive to inputs from script writing software.
19. The content production system of claim 17, wherein the interface is responsive to inputs from non-linear editing software.
20. The content production system of claim 17, wherein the interface is responsive to direct user inputs.
21. The content production system of claim 18, wherein the script writing software has the ability to open a window during script-writing and to create or edit a content asset.
21. A method for creating an interactive broadcast event including content assets for display with broadcast content, comprising:
creating an episode file with a number of content assets, each asset including one or more of text, graphics, video, and functionality; and
associating each content asset with a location in a script andor pre-finalized version of the broadcast event.
22. The method of claim 21, further comprising, when the broadcast event content is finalized, associating the content assets with a time code in the broadcast event.
23. The method of claim 21, wherein the broadcast event is over television.
24. The method of claim 21, wherein the broadcast event is over radio.
25. The method of claim 21, wherein the broadcast event is over the Internet.
26. The method of claim 21, wherein the content assets are displayed at the user end on the same display as the broadcast content.
