    Abstract: First and second users log in using at least one of a plurality of respective communication devices. Address information of the communication devices used by the first and second users to log in are sent to respective first and second servers, separated from each other by at least one wide area network. A user identifier for the second user is displayed in a quick dial list of user identifiers selected by the first user. The first user selects the displayed second user's identifier to request communication with the second user. The first user also selects a communication type. In response, the first server is queried to obtain the current address information for the selected second user. The received address information is used to establish the selected communication type, over the wide area network, between the first and second users.

    Abstract: A content storage and distribution networked system is described. The system includes at least one local network at a first physical premises, at least one audio-video storage device in communication with the local network, and at least two client devices in communication with the local network. The audio-video storage device is configured to store at least one media file, which includes at least video. The first client device is configured to enable the two client device to simultaneously access the at least one media file stored on the audio-video storage device. The system is configured to cause playback of media that is associated with the retrieved media file, and to enable the user of the first client device to operate on the playback of the media associated with the retrieved media file, using at least the operations of start, stop, pause, fast forward, and reverse.

    Abstract: A user logs in, at a first address, using a first communication device and establishes communication with an associated server using a wireless communication link. The user enables the first user to log in, at a second address, using the first communication device and establish communication with an associated server. Another user can log in using one or more communication devices. User identifiers for a second user are displayed in a quick dial list for a first user. When the first user selects the second user's identifier, the second user's address information is obtained and used to establish communication between these users.

    Abstract: A multimedia collaboration system that integrates separate real-time and asynchronous networks—the former for real-time audio and video, and the latter for control signals and textual, graphical and other data—in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mixing technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.
