Abstract

In a multimedia environment, end-users are provided with the ability to effectively access, manipulate and share one or more multimedia objects, or select portions thereof, independent of the terminal and/or network capabilities that are associated with the terminals employed by each end-user. This may be accomplished, for example, by identifying a set of multimedia data that is stored in a multimedia database that is accessible by each end-user. The set of multimedia data is then adapted in accordance with an information adaptation service and modified in accordance with a transcoder/scalability service. The functions provided by both of these services are based on a number of user preferences and based on a number of terminal and communication (e.g., network) connection capabilities associated with the terminals corresponding to each of the end-users that are to have access to the modified set of multimedia data.

Claims

1. A method for providing an intelligent multimedia services environment in a network, comprising the steps of:

responsive to a request by an end user, a first terminal device coupled to the network establishing a session with a media server and initiating a multimedia application that is shared by a second terminal device;

simultaneously, the first and second terminal devices sharing and manipulating multimedia data from one or more multimedia databases;

selecting the multimedia data according to user preferences utilizing a first application associated with the multimedia application;

adapting the multimedia data according to terminal device capabilities and network capabilities utilizing a second application associated with the multimedia application;

providing communication between the first terminal device and the second terminal device and the multimedia data and the multimedia application;

determining preferences of the first and second terminal devices; and

automatically adapting the multimedia data to satisfy the determined preferences and the terminal device and network capabilities of the first and second terminal devices prior to sending the multimedia data to the first and second terminal devices.

2. The method of claim 1, further comprising the step of transmitting commands between the first and second terminal devices defining operations and manipulations required in the shared multimedia data received by the first and second terminal devices.

3. The method of claim 1, wherein the determined preferences of the terminal devices include user preferences, terminal device capabilities, and network capabilities.

4. The method of claim 3, further comprising the step of sharing preferences of each of the first and second terminal devices with all connected terminal devices.

5. The method of claim 4, further comprising the step of storing the user preferences, terminal device capabilities and network capabilities at a Universal Resource Locator (URL) address.

6. The method of claim 5, further comprising the steps of:

identifying a multimedia data set stored in the one or more multimedia data bases;

utilizing the second application to modify the multimedia data set according to the user preferences, terminal device capabilities; and

network capabilities, wherein the second application is a transcoder/scalability service; and

making the modified multimedia data set available to one or more terminal devices connected to the network.

7. The method of claim 6, further comprising the steps of:

scaling the modified multimedia data set according to one or more significance values associated with each element of the modified multimedia data set; and

encoding the modified multimedia set according to the terminal capabilities and communication connection capabilities.

8. The method of claim 6, wherein the multimedia data set comprises one of, or a combination of two or more:

a still image;

one or more regions of interest of the still image;

a cropped portion of the still image;

a video object; and

a segment of the video object.

9. The method of claim 6, wherein the user preferences comprise:

a number of elements that constitute the multimedia data set,

a significance value assigned to each element of the multimedia data set; and

a price associated with making the modified multimedia data set available to the one or more terminal devices.

10. The method of claim 6, wherein the terminal device capabilities include:

a level of resolution and an amount of processing power associated with each of the one or more end user terminal devices connected to the multimedia data set.

11. A multimedia system associated with a network, comprising:

a first terminal device coupled to the network for establishing a session with a media server and for initiating a multimedia application;

a second terminal device for simultaneously sharing and manipulating multimedia data with the first terminal device, from one or more multimedia databases;

a server coupled with, and providing communication between, the first terminal device and the second terminal device and the multimedia data and the multimedia application;

a first application associated with the multimedia application for selecting the multimedia data according to user preferences

a second application associated with the multimedia application for adapting the multimedia data according to terminal device and network capabilities; and

at least one transcoder coupled with the media server for automatically adapting the multimedia data to satisfy the preferences of the first and second terminal devices and the capabilities of the network and the first and second terminal devices prior to sending the adapted multimedia to the first and second terminal devices.

12. The multimedia system of claim 11, further comprising means for transmitting commands between the first and second terminal devices defining operations and manipulations required in the shared multimedia data received by the terminal devices.

13. The multimedia system of claim 11, wherein the determined preferences of the first and second terminal devices include user preferences, terminal device capabilities;

and network capabilities.

14. The multimedia system of claim 11, wherein the at least one transcoder further comprises a scalability function for modifying the multimedia data.

15. The multimedia system of claim 14, wherein the transcoder is capable of communicating with each of the first and second terminal devices over a network connection.

16. The multimedia system of claim 15, wherein the transcoder is associated with a server.

17. The multimedia system of claim 15, wherein the transcoder is associated with a gateway device.

18. The multimedia system of claim 11, wherein the multimedia data comprises one of, or a combination of:

a still image;

one or more regions of interest of the still image;

a cropped portion of the still image;

a video object; and

a segment of the video object.

19. The multimedia system of claim 11, further comprising:

a multimedia data set stored in the first and second multimedia data bases;

a transcoder/scalability means for encoding, scaling and compressing the multimedia data set according to the user preferences, terminal device capabilities; and

network capabilities; and

a means for making the modified multimedia data set available to one or more terminal devices.

20. The multimedia system of claim 11, wherein the server further comprises a multipoint controller.
