20140181318 | MULTIMEDIA COMMUNICATION CONTROL UNIT AS A SECURE DEVICE FOR MULTIMEDIA COMMUNICATION BETWEEN LAN USERS AND OTHER NETWORK USERS - A system and method for providing multimedia communication between a firewall protected, LAN based endpoint and an endpoint that is external to the LAN. A logical port of a multimedia communications control unit is attached to the LAN behind the firewall. Another logical port of the multimedia communications control unit is attached to the external endpoint. Multimedia communication data, consisting of call management data and media data, can be exchanged between the endpoints via the multimedia | 06-26-2014 |
20120206564 | Control Unit for Multipoint Multimedia/Audio System - The present invention is a system and a method for providing a control unit for a multipoint multimedia/audio conference that enables one or more participants to take part in more than one conference simultaneously. The control unit can operate in audio and/or video sections of an MCU and/or Management and Control System (MCS). The MCS, in an exemplary embodiment of the present invention, controls the participation of at least one participant in more than one conference simultaneously by using a Cross-Conference Database (CCDB). The MCU performs connection changes affecting which participants are associated with one or more conferences based on the information that is stored in the CCDB. | 08-16-2012 |
20090284581 | DELAY REDUCTION FOR TRANSMISSION AND PROCESSING OF VIDEO DATA - The present invention is a method and system for reducing delay in video communication, including, for example, video transcoding and continuous presence in a multipoint multimedia conference. The video communication control unit reduces such delay by processing a video stream in a small number of macroblocks referred to as “chunks,” without waiting to get a full frame of video data. Instead, the incoming video stream is converted into decoded chunks. These decoded chunks are transferred to an output module without waiting to decode an entire frame. An encoder in the output module encodes the decoded chunks (also referred to as encoder chunks), and transfers them to an end user without waiting for the entire frame to be processed. Thus, reducing the delay in waiting for the entire frame of video data provides improved real-time video communication. | 11-19-2009 |
