Abstract

A system and method allow an Internet user to act as a broadcast session conductor by assembling audiovisual information in a multimedia document, and broadcasting that information to a predetermined group for simultaneous viewing. During the network broadcast, members of the predetermined group can interact with the Internet conductor using a standard telephone or other audio connection. The broadcast information may be used for such sessions as on-line training/teaching seminars, telemarketing, teleshopping and other multimedia events.

Claims

1. A method for broadcasting information over a network, comprising:

identifying, by a broadcast session conductor, a broadcast audience to receive a broadcast session;

determining and locating in real time, based on a profile of the broadcast audience, items to be broadcast during the broadcast session that are located at different locations;

collecting the items from their location to a central broadcast system, wherein the locations can include floppy or hard drive, websites, remote server or CDs;

creating, by the broadcast session conductor, the broadcast session for the identified broadcast audience based on audiovisual information; and

broadcasting the broadcast sessions in real time for reception only by the identified broadcast audience over the network or providing secured access to the broadcast audience for manual retrieval of the broadcast session.

2. The method of claim 1, wherein the step of creating the broadcast session comprises:

retrieving information from an audiovisual database;

creating a multimedia document based on the retrieved information;

specifying a length of the broadcast session;

specifying a required bandwidth for the broadcast session;

specifying a participation list; and

saving the broadcast session in a database.

3. The method of claim 2, wherein the multimedia document is created using a multimedia authoring tool.

4. The method of claim 2, wherein the multimedia document includes at least two of text, video, and audio data.

5. The method of claim 1, wherein the broadcast audience is designated by providing members of the broadcast audience with a code, the code being entered at a terminal of each of the members to access the broadcast session.

6. The method of claim 5, wherein a controller queries the terminal of each of the members to determine if the code is correct.

7. The method of claim 1, wherein the broadcast session is broadcast in MPEG-2 format.

8. The method of claim 1, wherein the broadcast session is broadcast in HTML format.

9. The method of claim 1, wherein the broadcast session is broadcast using at least one of satellite television, cable television, wireless cable television, and broadcast television.

10. The method of claim 1, further comprising the step of establishing an audio link between members of the broadcast audience and the broadcast session conductor.

11. The method of claim 10, wherein the audio link communicates transaction information related to the broadcast session.

12. The method of claim 5, wherein the broadcast session is made available to predetermined terminals connected to the network, the predetermined terminals being designated by the broadcast session conductor specifying the code.

13. The method of claim 11, wherein users of the predetermined terminals and the broadcast session conductor communicate using telephone stations, white boards and chat rooms.

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

16. The system of claim 15, wherein the broadcast session comprises:

a multimedia document, the multimedia document including at least two of audio, video, and text data;

a broadcast length; and

a broadcast bandwidth.

17. The system of claim 15, wherein the broadcast session audience is designated by providing each member of the broadcast session audience with a code, the code being entered at a terminal of a member of the broadcast session audience to access the broadcast session.

18. The system of claim 15, wherein the broadcast session is broadcast in MPEG-2 format.

19. The system of claim 15, wherein the broadcast session is broadcast in HTML format.

20. The system of claim 15, further comprising a broadcast center, the broadcast center transmitting the broadcast session by at least one of satellite television, cable television, wireless cable television, and broadcast television.

21. The system of claim 15, further comprising an audio link, the audio link connecting members of the broadcast session audience and the broadcast session conductor.

22. The system of claim 21, wherein the audio link communicates transaction information related to the session broadcast.

23. The system of claim 17, wherein the broadcast session is made available to predetermined terminals connected to the Internet, the predetermined terminals designated by a broadcast session conductor specifying the code.

24. The method of claim 1, wherein the broadcast session is at least one of narrowcast, multicast, switched connection and encrypted transmission.

25. The method of claim 1, wherein the broadcast session and the audiovisual information are stored in and retrieved from at least one database.

26. The method of claim 10, wherein the audio link is established via one or more of a telephone network and a data network, audio communication received from the audio link may be selectively broadcast as part of the broadcast session.

27. The method of claim 1, further comprising establishing a white board space as a communication link between one or more members of the broadcast audience and a broadcast session conductor.

15. A system for broadcasting information over a network, comprising:

a profile determining device that determines characteristics of a broadcast audience;

a locating and retrieval device for locating and retrieving items in real time for assembly in a broadcast session, wherein a location can include floppy or hard drive, website, remote server or CDS;

a database that stores broadcast sessions created by a broadcast session conductor, for an identified broadcast audience from audiovisual information; and

a broadcast device that broadcasts the broadcast sessions in real time for reception only by the identified broadcast audience over the network, the broadcast audience being identified by the broadcast session conductor, before the broadcast.
