Abstract

The present invention relates to video conferencing and multimedia messaging, and takes advantage of the capabilities of the communication system to which the audio participants are connected, in order to increase the performance of all the participants in a mixed conference. In a preferred embodiment, the audio participants are provided with a MMS device, and a MMS Engine captures periodically, or at certain events, video conference data attached to MMS messages and addressed to the MMS device. In the opposite direction, the MMS device provides multimedia data to the conventional video conference participants by attaching the multimedia data to MMS messages, which are sent to the IP-addressable MMS Engine. The MMS Engine separates the multimedia data and converts it to a format compatible with the video conference. The converted multimedia data is then provided to video conference participants, and treated like any other multimedia stream included in the video conference.

means for transmitting said converted multimedia data to the respective video conferencing End Point; and

means for initiating said means for converting and transmitting periodically or at a predefined event.

11. The MMS Engine according to claim 10, wherein the MMS receiving unit is further configured to determine that the MMS message is associated with the video conference by investigating a sender, or a receiver address, included in the MMS message, from which a conference ID of the video conference is found, and

the transmission unit is further configured to transmit the converted multimedia data to the video conferencing End Point according to the conference ID.

12. The MMS Engine according to claim 10, wherein the video conference involves an MCU through which said converted multimedia data is transmitted prior to reaching said respective video conferencing End Point.

13. The MMS Engine according to claim 10, wherein said predefined event occurs when a difference between previously received multimedia data and corresponding multimedia data generated in the MMS device is larger than a predefined threshold.

14. The MMS Engine according to claim 10, wherein said predefined event occurs at a time when one or more video or audio participants leaves or enters the video conference.

15. The MMS Engine according to claim 10, wherein said multimedia data is an image stored in the MMS device or captured by a camera connected to, or integrated in, the MMS device.

16. The MMS Engine according to claim 10, wherein said multimedia data is a video sequence.

17. The MMS Engine according to claim 15, wherein the converted multimedia data is merged, creating real-time video.

18. The MMS Engine according to claim 10, wherein said converted multimedia data is treated as any other multimedia stream associated with the video conference.

19. The MMS Engine according to claim 10, wherein the MMS Engine is incorporated in, or connected to, a Gateway, an MCU or an End Point.

20. A method enabling MMS capabilities in a video conference including one or more video participants associated with a respective video conferencing End Point, and one or more audio participants associated with a respective MMS device, comprising steps of:

capturing video conferencing data from a data source originating from one or more video conferencing End Points or MCUs;

converting said video conferencing data to a MMS attachable format;
