Parameters for overlay handling for immersive teleconferencing and telepresence for remote terminals

1. A method for video conferencing, executable by a processor, comprising:

receiving video data associated with an immersive teleconferencing session, wherein the received video data is associated with a sender;

identifying a parameter associated with the video data, wherein the parameter specifies overlay data associated with the immersive teleconferencing session, and wherein the parameter indicates whether a receiver is allowed to use overlays from another sender not associated with the received video data; and

displaying the video data with one or more overlays based on the identified parameter.

2. The method of claim 1 , wherein the parameter may be offered a Session Description Protocol (SDP).

3. The method of claim 1 , wherein the parameter is negotiated during an initial offer-answer negotiation or during the immersive teleconferencing session.

4. The method of claim 1 , wherein the parameter defines maximum number of overlays and restricts a number of overlay instances at a particular time.

5. The method of claim 1 , wherein the parameter defines a list of overlay ids shared by the sender at a given time instance.

6. The method of claim 1 , wherein the parameter defines a list of overlay ids shared by the sender and supported by the receiver at a given time instance.

7. The method of claim 1 , wherein the parameter defines a prioritized list of overlay ids the receiver is allowed to use other than overlays shared by the sender.

8. The method of claim 1 , wherein the parameter defines a list of allowed senders from whom the receiver may receive and use overlays.

9. A computer system for video conferencing, the computer system comprising:

one or more computer-readable non-transitory storage media configured to store computer program code; and

one or more computer processors configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:

receiving code configured to cause the one or more computer processors to receive video data associated with an immersive teleconferencing session, wherein the received video data is associated with a sender;

identifying code configured to cause the one or more computer processors to identify a parameter associated with the video data, wherein the parameter specifies overlay data associated with the immersive teleconferencing session, and wherein the parameter indicates whether a receiver is allowed to use overlays from another sender not associated with the received video data; and

displaying code configured to cause the one or more computer processors to display the video data with one or more overlays based on the identified parameter.

10. The computer system of claim 9 , wherein the parameter may be offered a Session Description Protocol (SDP).

11. The computer system of claim 9 , wherein the parameter is negotiated during an initial offer-answer negotiation or during the immersive teleconferencing session.

12. The computer system of claim 9 , wherein the parameter defines maximum number of overlays and restricts a number of overlay instances at a particular time.

13. The computer system of claim 9 , wherein the parameter defines a list of overlay ids shared by the sender at a given time instance.

14. The computer system of claim 9 , wherein the parameter defines a list of overlay ids shared by the sender and supported by the receiver at a given time instance.

15. The computer system of claim 9 , wherein the parameter defines a prioritized list of overlay ids the receiver is allowed to use other than overlays shared by the sender.

16. The computer system of claim 9 , wherein the parameter defines a list of allowed senders from whom the receiver may receive and use overlays.

17. A non-transitory computer readable medium having stored thereon a computer program for video conferencing, the computer program configured to cause one or more computer processors to:

receive video data associated with an immersive teleconferencing session, wherein the received video data is associated with a sender;

identify a parameter associated with the video data, wherein the parameter specifies overlay data associated with the immersive teleconferencing session, and wherein the parameter indicates whether a receiver is allowed to use overlays from another sender not associated with the received video data; and

display the video data with one or more overlays based on the identified parameter.

18. The computer readable medium of claim 17 , wherein the parameter may be offered a Session Description Protocol (SDP).

19. The computer readable medium of claim 17 , wherein the parameter is negotiated during an initial offer-answer negotiation or during the immersive teleconferencing session.

20. The computer readable medium of claim 17 , wherein the parameter defines maximum number of overlays and restricts a number of overlay instances at a particular time.
