摘要:
An end station for a videoconference/multimedia conference is disclosed, where the end station requests, receives and displays multiple video streams. Call control messages request video streams with specified video policies. A static policy specifies a constant source video stream, e.g., a participant. A dynamic policy dynamically maps various source streams to a requested stream and shows, for example, the current speaker, or a round robin of participants. A network access device, e.g., a media switch or a video composition system, mediates between the multi-stream end station and the core conference system. Multi-stream endpoints need not handle the complexity of directly receiving video according to a potentially wide variety of call control protocols, formats, and bit-rates. Multi-stream endpoints decentralize compositing video streams, which increases functional flexibility and reduces the need for centralized equipment.

Disclosed are conferencing systems, devices, architectures, and methods for implementing a trigger-based conferencing system to facilitate increased productivity meeting participation. An exemplary method, in accordance with embodiments, of managing a workflow application in a conference, where the conference includes a plurality of events, can include: (i) creating a trigger by defining a predicate and action for the trigger; (ii) registering the trigger to at least one of a plurality of detection points; (iii) evaluating the trigger's predicate each time any of the detection points against which it is registered are encountered; and (iv) executing actions associated with the trigger if the predicate evaluation is positive, where execution of the actions can result in a state change in the conference.

Techniques for scheduling a task include receiving task data and quorum data. Task data describes tasks to be performed by one or more participants. Quorum data indicates a participant set of one or more participants to perform each task. Current user data may also be received. Current user data describes a current task set of one or more tasks currently being performed by a particular participant. Either or both of the task data and the current user data describe interruptibility through a particular medium of a plurality of communications media. A particular time interval to schedule a particular task is determined based at least in part on the interruptibility of the task or the particular participant. These techniques allow either or both unscheduled tasks and previously scheduled tasks to be moved to time intervals that overlap other scheduled tasks, including tasks currently being performed by a participant.

According to one embodiment of the invention, a method for maintaining video capability includes receiving at a device from a source a plurality of packets representative of video data. The plurality of packets include a payload and a header. The method also includes transmitting a copy of the plurality of received packets back to the source with a modified header and an unmodified payload. The transmitted copy provides data representative of the video data.

摘要:
Techniques for dynamically mapping source video streams of sources to the requested destination video streams based on a policy are provided. The source video streams that are mapped to the destination video streams are changed based on events that cause changes in the mapping based on the policy. The mappings may be managed by a media switch remote from the end device or by an event aware stream router associated with the end device. The mappings are used to display images of participants associated with the source video streams where position changes in images displayed are minimized when events occur.

The present invention provides optical fiber communication cable assemblies useful for separating and conveying individual fibers from a multiple optical fiber cable to connectors in a protective manner. The optical fiber cable assembly is suitable for outdoor use and includes a (i) cable with multiple optical fibers; (ii) a furcation unit attached to the cable for directing individual optical fibers from the cable to furcation legs; and (iii) multiple furcation legs receiving at least one of the optical fibers. The furcation legs include (i) a buffer tube surrounding the optical fiber; (ii) strength members surrounding the buffer tube; and (iii) a jacket surrounding the strength members. The furcation legs typically exhibit a tensile rating of at least about 50 pounds (lbf), more typically 100 pounds (lbf) or more. Moreover, the furcation legs typically exhibit total shrinkage of less than about 2 percent when cycled from +23° C. to −40° C. to +70° C. to −40° C.

According to one embodiment of the invention, a method for use in establishing communications includes receiving an invitation for communication at a first device. The invitation for communication is devoid of video capability information. In response to receiving the invitation for communication, the method includes transmitting, from the first device, a signal other than an SDP signal. This signal includes video capability information. After transmission of the signal, the first device receives an offer and incorporates the video capability information included in the signal.
