Abstract

The present invention provides a method by which the capabilities of a device that is not specifically adapted for use as a video endpoint can be determined. The capabilities of the device may be, for example, whether or not an application required for the device to act as a video endpoint is present at the device. If the application is not present on the device then the invention provides means by which the device can access the application. The capabilities of the device that are determined may, alternatively, be properties of the device, such as the amount of free memory available to the device'"'"'s operating system. By determining properties of the device any application being used by the device to connect to a video conference can be altered in order to improve the device'"'"'s connection to a video call.

Claims

1. A method of configuring a device so that it can connect to a video conference call hosted by a multi-conference unit (MCU), the method comprising the steps of:

a) the MCU transmitting an applet to the device;

b) the applet being adapted to execute on the device and determining whether a video endpoint application is present on the device; and

c) causing a video endpoint application to be transmitted to the device if it is not present on the device thereby configuring the device so that it can communicate with the MCU.

2. A method of configuring a device according to claim 1 further comprising the step of the device transmitting an initiation message requesting a connection to the MCU and the MCU transmitting the applet in response to the initiation message.

3. A method of configuring a device according to claim 1 wherein the applet is downloaded from one of the group comprising the MCU and an external server.

4. A method of configuring a device according to claim 1 wherein the video endpoint application includes one of the group comprising:

a codec a user interface and a protocol processor.

5. A method of configuring a device according to claim 4 wherein the protocol processor is adapted to encapsulate media data to be transmitted by the device into a streaming protocol.

6. A method of configuring a device according to claim 5 wherein the streaming protocol includes one of the group comprising User Datagram Protocol (UDP), real-time transmission protocol (RTP), Transmission Control Protocol (TCP) or Hypertext Transfer Protocol (HTTP).

7. A method of configuring a device according to claim 1 wherein the applet determines whether the video endpoint application is the most recent video endpoint application available and, if it is not, causes the device to download the most recent version of the video endpoint application.

8. A method of configuring a device according to claim 1 further comprising the applet determining whether all the video endpoint applications are present on the device and downloading any video endpoint application not present on the device to the device.

9. A method of configuring a device according to claim 1 wherein the all the video endpoint applications required to configure the device are downloaded in a bundle.

10. A method of configuring a device according to claim 1 wherein the applet monitors properties of the device and alters the configuration of a video endpoint application in response to a change in the properties of the device.

11. A method of configuring a device according to claim 10 wherein a property of the device is selected from the group comprising:

the free memory of the device, the processing power of the device, the device'"'"'s operating system, whether the device supports echo cancellation, the resolution at which media data is captured by the device and the resolution at which the device can display images.

12. A method of configuring a device according to claim 10 wherein the step of altering the configuration of the device comprises changing the codec executing on the device.

13. An MCU including a software applet, the applet being arranged for download to and execution on a device;

the applet when executed on the device being arranged to cause the device to determine whether the device includes a video endpoint application configured to enable the device to communicate with a multiconference unit (MCU); and

to cause a video endpoint application to be transmitted to the device from the MCU if it is not present on the device thereby configuring the device so that it can communicate with the MCU.

14. An applet being executable on a device, and adapted to:

a) determine whether the device includes a video endpoint application configured to enable the device to communicate with a multiconference unit (MCU); and

b) cause a video endpoint application to be transmitted to the device if it is not present on the device thereby configuring the device so that it can communicate with the MCU.
