Method and system for handling content in videoconferencing
First Claim
1. A method for distributing content received from a content delivery endpoint in a multipoint multimedia conference, comprising:
- identifying capabilities of a first receiving endpoint;
identifying a quality of a connection that carries the content from a multipoint control unit toward the first receiving endpoint;
associating at the multipoint control unit, based on the identified capabilities and quality, content delivery resources for distributing the content toward the first receiving endpoint, wherein the content delivery resources associated with the first receiving endpoint differ from content delivery resources associated with a second receiving endpoint; and
transferring the content toward the first and second receiving endpoints via the associated content delivery resources,wherein the content comprises one or more data files to be presented during the multimedia conference, andwherein the first receiving endpoint is associated with a first quality level if the identified capabilities of the first receiving endpoint comprise a capability to decode compressed content received from the content delivery endpoint and the connection is identified as a high quality connection.

Abstract
A technique allows delivering content in a videoconference among a plurality of conferees in multiple quality levels. Content distributed from a multipoint control unit that is connected to an endpoint that delivers the content to receiving endpoints may have two or more quality levels. The quality level can be adapted to the capabilities of the receiving endpoints and the current quality of the connection that is used to deliver the content toward the receiving endpoints. The quality level associated with an endpoint may change during a session dynamically, adapting the delivery mode to changes in the condition of the connection between the receiving endpoints and the multipoint control unit.

22. A multipoint control unit comprising:
-
a first transmitting network interface module configured to receive packets carrying data of received compressed content from a content transmitting endpoint and transfer the data of the received compressed content toward a common interface; a decoder, configured to obtain from the common interface the data of received compressed content, decode the data of the received compressed content and generate decoded content; an encoder configured to compress the decoded content and provide a second data of compressed content; and a second transmitting network interface module configured to obtain, from the common interface, the data of the received compressed content or to obtain the second data of compressed content and transmit packets that carry the obtained data toward a first receiving endpoint; and a content manager module configured to identify capabilities of the first receiving endpoint, identify a quality of a connection associated with the first receiving endpoint, and accordingly instruct the second transmitting network interface module whether to obtain the data of the received compressed content or the second data of compressed content, wherein the content comprises one or more data files to be presented during a multimedia conference, and wherein the first receiving endpoint is associated with a first quality level if the identified capabilities of the first receiving endpoint comprise a capability to decode compressed content received from the content transmitting endpoint and the connection is identified as a high quality connection. - View Dependent Claims (23, 24, 25, 26, 27)

28. A non-transitory computer readable medium, comprising instructions that when executed by one or more processors of a multipoint control unit, cause the multipoint control unit receiving content from a content delivery endpoint to:
-
identify capabilities of a first receiving endpoint of a plurality of receiving endpoints; identify a quality of a connection associated with the first receiving endpoint; based on the identified capabilities and quality, associate content delivery resources of the multipoint control unit for transmitting the content toward the first receiving endpoint, wherein the content delivery resources associated with the first receiving endpoint differ from content delivery resources associated with a second receiving endpoint of the plurality of receiving endpoints; and transfer the content toward the first receiving endpoint and the second receiving endpoint, wherein the content comprises one or more data files to be presented during a multimedia conference, and wherein the first receiving endpoint is associated with a first quality level if the identified capabilities of the first receiving endpoint comprise a capability to decode compressed content received from the content delivery endpoint and the connection is identified as a high quality connection. - View Dependent Claims (29, 30, 31)
