System for automatically adding additional data stream to existing media connection between two end points upon exchange of notifying and confirmation messages therebetween
First Claim
1. An automatic method for adding an additional data stream to an existing media source between two endpoints comprising the following steps:
- a. a first endpoint identifying the availability of said additional data stream to a second endpoint via a first message containing a reference to said existing media source;
b. said first endpoint notifying said second endpoint of the desire to connect to provide said additional data stream via a second message;
c. said second endpoint notifying said first endpoint of confirmation to connect via a third message; and
d. said first and said second endpoint establishing communication to provide said additional data stream to said second endpoint, said additional data stream being associated in said first endpoint and said second endpoint with said existing media source.

Abstract
An automatic method for adding an additional data stream, such as auxiliary teleconference data, to an existing media connection between two endpoints, such as a teleconference between teleconferencing systems. A first endpoint identifies the availability of a second data stream to a second endpoint via a first message which references the existing media connection. The first endpoint notifies the second endpoint of the desire to connect via a second message. The second endpoint notifies the first endpoint of confirmation to connect via a third message. The first and the second endpoint then establish communication wherein the additional data stream is associated in a first endpoint and the second endpoint with the existing media connection.

13. An apparatus in a first endpoint for adding an additional data stream to an existing media source between two endpoints comprising:
-
a. a first circuit coupled to a communication interface, said first circuit creating and transmitting a first message containing a reference to said existing media source which identifies the availability of said additional data stream to a second endpoint; b. a second circuit coupled to said communication interface, said second circuit receiving a second message from said second endpoint notifying said first endpoint of confirmation to receive said additional data stream; and c. a third circuit coupled to said communication interface, said third circuit providing said additional data stream to said second endpoint such that said second endpoint interprets said additional data stream as being received from said first endpoint. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. An automatic method for adding an additional media stream associated with an existing media stream transmitted between two endpoints comprising the following steps:
-
a. a first endpoint identifying the availability of said additional media stream to a second endpoint via a first message containing a reference to said existing media stream; b. said second endpoint notifying said first endpoint of confirmation to connect via a second message; and c. said first and said second endpoint establishing communication to provide said additional media stream to said second endpoint, said additional media stream being associated in said second endpoint with said first endpoint. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. An apparatus for adding an additional media stream associated with an existing media stream transmitted from a first endpoint to a second endpoint, said apparatus comprising:
-
a means for identifying an availability of said additional media stream to said second endpoint via a first message containing a reference to said existing media stream; a means for receiving a confirmation to connect via a second message from said second endpoint; a means for providing said additional media stream to said second endpoint, said additional media stream being associated at said second endpoint with said first endpoint.

38. A computer readable medium in a digital processing system which is a first endpoint that is transmitting an existing media stream to a second endpoint, said medium containing executable computer program instructions which when executed in said digital processing system cause said system to perform steps comprising:
-
identifying an availability of an additional media stream to said second endpoint via a first message containing a reference to said existing media stream; receiving a confirmation to connect via a second message from said second endpoint; providing said additional media stream to said second endpoint, said additional media stream being associated at said second endpoint with said first endpoint.
