Abstract

The invention facilitates asynchronous interaction between a geographically separated facilitator and at least one user. The said invention provides asynchronous interaction between rural classrooms (teacher-student community) and expert teachers to increase the outreach of the expert teachers much beyond that is permitted with the teachings of the prior art.

Claims

1. A method for enabling asynchronous interaction between a first station and a second station, the method comprising:

receiving, at the second station, a multimedia-based message via a first network having a first bandwidth, the second station being geographically separated from the first station, wherein the multimedia-based message comprises embedded metadata, wherein the metadata comprises a media time point during a duration of the display of the multimedia-based message for at least one rhetoric question hierarchy (RQH);

obtaining, based on the embedded metadata, via a second network having a second bandwidth, at least one RQH associated with the multimedia-based message from a content repository, wherein the first bandwidth is larger than the second bandwidth;

displaying the multimedia-based message and the information request at the media time point included in the metadata;

receiving a first response to a first question in the at least one RQH; and

evaluating the first response.

2. The method of claim 1, further comprising at least one of:

displaying a second question based on the evaluation of the first response and the metadata; and

displaying a plurality of subsequent questions, wherein the plurality of subsequent questions are based on the metadata and the evaluation of the second information response with respect to the preceding information request.

3. The method of claim 1, further comprising:

obtaining a user query;

transmitting the query to the content repository via the second network; and

retrieving a response to the query from the content repository via the second network, the response being provided by a third station.

4. The method of claim 3, wherein the query and the response comprise at least one of:

a text, an audio, or an audio-visual format.

5. The method of claim 1, wherein the at least one RQH is an embedded rhetoric question having at least one of:

a text, an audio, or an audio-visual format.

6. The method of claim 1, wherein the first network is a satellite based Direct-To-Home network.

7. The method of claim 1, wherein the second network is the Internet.

8. The method of claim 1, wherein the second station is connected to the first network via a set top box.

9. The method of claim 1, wherein the second station is connected to the second network via a multimedia communication device, the multimedia communication device being a Home Infotainment Platform box connected to at least a set top box.

10. The method of claim 1, wherein the second station is connected to the second network via a multimedia communication device, the multimedia communication device providing a regional language support.

11. The method of claim 1, wherein the multimedia-based message is transmitted from the first station to the second station via a broadcasting station.

12. A method for enabling asynchronous interaction between an authoring station and at least one remote student station associated with a plurality of students, the method comprising:

receiving, at the at least one remote student station, a lecture via a first network having a first bandwidth, wherein the lecture comprises embedded metadata, wherein the metadata comprises a media time point during a duration of the display of the multimedia-based message for at least one question;

obtaining, based on the embedded metadata, via a second network having a second bandwidth, at least one question associated with the lecture from a content repository, wherein the first bandwidth is larger than the second bandwidth;

displaying the lecture and the at least one question at the media time point included in the metadata;

receiving, a first response with respect to the at least one question;

evaluating the first response; and

displaying a second response based on the evaluation of the first response.

13. The method of claim 12, further comprising at least one of:

obtaining a student request;

transmitting the student request to the content repository via the second network; and

retrieving a tutor response with respect to the student request from the content repository via the second network, the tutor response being provided by a tutor station.

14. The method of claim 12, wherein:

the lecture, the metadata, and the at least one question are generated by the authoring station;

the lecture is transmitted from the authoring station to the student station via a broadcasting station; and

the metadata and the at least one question are transmitted from the authoring station to the content repository.

15. A system for enabling asynchronous interaction between an authoring station and at least one remote student station associated with a plurality of students, the system comprising:

a student station configured to;

receive a lecture via a first network having a first bandwidth, wherein the lecture comprises embedded metadata, wherein the metadata comprises a media time point during a duration of the display of the multimedia-based message for at least one question;

obtain, based on the embedded metadata, via a second network having a second bandwidth, at least one question associated with the lecture from a content repository, wherein the first bandwidth is larger than the second bandwidth;

display the lecture and the at least one question at the media time point included in the metadata;

receive a first response with respect to the at least one question;

evaluate the first response, and

display a second response based on the evaluation of the first response.

16. The system of claim 15, wherein the student station includes at least one of:

a Home Infotainment Platform box that is connected to at least one of a set top box, a television set, or a remote control device.

17. The system of claim 16, wherein the student station further includes a voice capturing device and a video capturing device.

18. The system of claim 16, wherein the remote control device is configured to enable answering of the question.

19. The system of claim 15, wherein the student station is further configured to:

obtain a student request;

transmit the student request to the content repository via the second network; and

retrieve a tutor response with respect to the student request from the content repository via the second network, the tutor response being provided by a tutor station.

20. The system of claim 19, wherein the student request comprises an audio format.

21. The system of claim 15, further comprising:

an authoring station configured to generate the lecture, the metadata, and the at least one question; and

wherein the lecture is transmitted from the authoring station to a broadcasting station, the metadata and the at least one question is transmitted from the authoring station to the content repository, the broadcasting station is configured to broadcast the lecture via the first network, the first network is a satellite based Direct-To-Home network, and the content repository is configured to store the metadata and the at least one question.
