摘要： An end user computer is assigned a multicast content distribution group by a network service intelligence platform. The network service intelligence platform authenticates a token sent by the user and signed by a third part content controller, and provides the user with credentials for joining the group. The credentials include an authorization key as well as identifications of the user and the requested content. The credentials are encrypted and authenticated by the third party content controller. The user includes the encrypted and authenticated credentials in a join request sent to a network resource, such as an edge router. After verifying the credentials, the network resource adds the end user computer to the multicast group.

摘要： A system for providing multicast distribution of incrementally enhanced content is disclosed. The system may include encoding content by utilizing an incremental layer encoding algorithm to generate a low resolution base stream for content and one or more incremental streams for the content. The incremental streams may each have higher resolutions than the base stream. The system may provide the base streams and one or more of the incremental streams to a client device based on available bandwidth and based on the capabilities of the client device. Each of the streams of content may be provided to the client device by having the client device connect to one or more multicast sessions. As the streams are accessed by the client device, the client device may combine and decode the base streams, along with any accessed incremental streams, to obtain the content at an available resolution.

摘要： A client system includes a processor configured to obtain multicast information for a content item, the multicast information including information about a multicast session for a base stream and additional multicast sessions for available incremental streams. The processor is also configured to determine an available bandwidth, and to join a set of initial multicast sessions based on the available bandwidth, the set of initial multicast sessions including the multicast session for the base stream and at least one of the additional multicast sessions for the incremental streams. The processor is also configured to monitor a network condition, and to perform an action based on the network condition, the action selected from the group consisting of joining another of the additional multicast sessions, leaving one of the initial multicast sessions, and a combination thereof.

摘要： A graphical user interface, i.e., multimedia communications application program, for setting up and handling a multimedia call is disclosed that employs realistic metaphors of real life face-to-meetings in setting up and handling a multimedia call to establish a virtual meeting which is automatically reconfigured in response to user action. This is realized by taking advantage of prospective virtual meeting participants' already existing knowledge of how real life face-to-face meetings operate. To this end, the multimedia communications application program enables the virtual meeting participants through direct manipulation of the realistic graphical metaphors to establish a realistic virtual meeting room which is displayed on the screen of their workstation monitor. The virtual meeting room includes a table and chairs arranged in a realistic manner in the virtual meeting room. The virtual meeting room and table are automatically configured in response to user action in such a manner as to minimize the screen area displaying the virtual meeting room and, thereby, maximizing the screen area available for multimedia collaboration by the meeting participants. An empty chair is displayed at the table which indicates that at least one more participant can be added to the virtual meeting. Once a predetermined maximum number of participants have been included in the virtual meeting, the empty chair is no longer displayed.
