Abstract

In an embodiment, a videoconference system is provided in which a conference can be controlled by an end user (e.g., a participant of the conference) without the assistance of an operator. In another embodiment, the end user is presented with a graphical feature on an image associated with an ongoing conference that links to a menu, which in turn links to routines for selecting various options that change the setup of the conference. In yet another embodiment, the parameters of the conference can be changed while the conference is ongoing. In a further embodiment, the conference control unit includes a menu generator. Any combination of the above embodiments can be used together in one embodiment.

Claims

1. A method for controlling a video communication session whereby any of a plurality of users each using an endpoint can control a video control unit, each of the endpoints providing live video data to the video control unit, the method comprising:

transmitting from the video control unit to a given user'"'"'s endpoint a video signal, wherein the video signal comprises a composite of the live video data from at least one of the plurality of endpoints and further comprises at least one representation of a control option;

inputting the given user'"'"'s request at the endpoint in response to the control option;

sending a control signal carrying the request from the given user'"'"'s endpoint to the video control unit; and

responding to the control signal at the video control unit by changing parameters of the video communication session.

2. The method of claim 1, wherein the video control unit is a multipoint control unit.

3. The method of claim 1, wherein the video control unit is a media gateway.

4. The method to claim 1, wherein the sending supports sending a Dual Tone Multi-Frequency signal.

5. The method of claim 1, wherein the sending supports sending a far end camera control signal.

6. The method of claim 1, wherein the sending supports sending the user'"'"'s vocal signal.

7. The method of claim 1, wherein the sending supports sending a proprietary control signal.

8. The method of claim 1, wherein the representation of the option includes at least text data.

9. The method of claim 1, wherein the representation of the option includes data presented as a graphical shape.

10. The method of claim 1, wherein the representation of the option includes data presented as text within a graphical shape.

11. The method of claim 1, wherein responding further comprises generating a menu and transmitting that menu to the given user by at least

selecting menu characteristics from a bank of menu characteristics;

generating text images corresponding to text;

selecting graphic objects, to be used in the menu, from a bank of graphic objects; and

composing the menu by building the menu from the menu characteristics, the text image, and the graphic objects, and

transmitting the menu to the given user as a composite with the live video data from at least one of the plurality of endpoints.

12. The method of claim 1, further comprising generating a menu including text images and graphic objects.

13. The method of claim 1, wherein the control option comprises a menu selection, and wherein the responding comprises:

if the menu selection indicates a cursor movement, moving the cursor in a selected direction, and then providing another menu selection;

if the menu selection indicates an exit of a menu, closing the menu; and

if the menu selection indicates a selection of a routine, selecting the routine.

14. The method of claim 1, wherein the parameters of the video communication session include at least one parameter selected from a group consisting of a layout of the video communication session, a quality, a region of interest, and a visual effect.

15. The method of claim 1, wherein responding to the control signal includes at least one action selected from a group consisting of displaying a certain user, changing a volume, adding a user, removing a user, and altering the duration of the communication session.

16. A system comprising a control module configured to change parameters of a video communication session based on control signals from an endpoint of a video communication session user without assistance from an operator, the system comprising:

at least one menu generator configured to generate video data for at least one menu having at least one option selectable by the user; and

a video module configured to

incorporate into a video signal a composite of live video data from at least one of the plurality of endpoints and the video data for the menu, and to

transmit the video signal to an endpoint.

17. The system of claim 16, wherein the video module is part of a Multipoint Control Unit.

18. The system of claim 16, wherein the video module is part of a media gateway.

19. The system of claim 16, wherein the parameters can be changed by the user while the conference is ongoing.

20. The system of claim 16, wherein the control signals comprise at least one of the signal selected from the group consisting of a Dual Tone Multi-Frequency signals and a far end camera control signal.

21. The system of claim 16, wherein the parameters of the video communication system include at least one parameter selected from a group consisting of a layout of the video communication system, a quality, a region of interest, and a visual effect.

22. The system of claim 16, wherein the parameters of the video communication system include at least one parameter selected from a group consisting of a speaker output, a volume level, an added user, a removed user, and a duration of the communication session.

23. The system of claim 16, wherein the menu includes at least text data.

24. The system of claim 16, wherein the menu includes at least a graphical image.

25. The system of claim 16, wherein the menu generator comprises:

a text generator for adding text to images;

a bank of graphic objects for storing at least one graphic object used by the menu;

a builder for building the menu using the text from the text generator and the at least one graphic object from the bank of graphic objects; and

a controller for sending control signals to the text generator, the bank of graphic objects and the builder to form the menu.

26. The system of claim 16, wherein the video signal is capable of forming an image on a screen at the end point indicative of the menu and the live video data.

27. The system of claim 16, further comprising:

the endpoint; and

a network communicatively connecting the endpoint to the control module.

28. The system of claim 16, further comprising an audio unit for processing an audio stream from an endpoint, the audio unit recognizing at least a Dual Tone Multi-Frequency.

29. The system of claim 16, wherein the video module further comprises:

one or more input modules for receiving the live video data from one or more endpoints; and

a common interface communicatively connected to the one or more input modules.

30. The system of claim 29, wherein the video module further comprises one or more output modules that

receive signals from the common interface associated with the one or more input modules and the at least one menu generator;

compose the signals from the common interface into one composed video image; and

compress the composed video image to formulate the video signal.

31. A computer readable medium having stored thereon instructions for a method for controlling a video control unit at an endpoint, the method comprising:

transmitting from the video control unit to a given user'"'"'s endpoint a video signal, wherein the video signal comprises a composite of the live video data from at least one of the plurality of endpoints and further comprises at least one representation of a control option;

inputting the given user'"'"'s request at the endpoint in response to the control option;

receiving at the video control unit a control signal from the endpoint in response to the control option; and

responding to the control signal at the video control unit by changing parameters of the video communication session.

32. A method for interfacing between a plurality of endpoints and a video control unit in a video communication session, comprising:

generating at the video conferencing unit a video signal comprising a composite of live video data from at least one of the plurality of endpoints and video data indicative of at least one representation of a control option;

transmitting the video signal to the plurality of endpoints; and
