Abstract: A method of communication between a plurality of users is claimed. Two communication devices are registered with at least one communication network. At least one of the two communication devices is configured for wireless communication. Two users are allowed to use one of the two communication devices to connect to at least one communication network. A service record is maintained for each registered communication device. The service record includes the respective communication device's addressing information. A query is issued for a service instance associated with one of the two users in response to a request by the other user to establish communication. Addressing information of the second communication device is retrieved and a communication over at least one communication network established using the retrieved addressing information if a service instance is found.

Abstract: A collaboration initiation software product includes machine readable code to allow a first user to log in at a first device. The code is operable to cause the first device to communicate first user location-related information to a network to allow a server to maintain a service record. The code is operable to cause display of representations of at least two real-time communication types from the group consisting of video communication, audio communication and data conferencing. The code is operable to allow the user to select a real-time communication type. The code is operable to cause display of a user identifier for a second user in a directory on the first device. The code is operable to respond to the first user's selection of the displayed identifier to cause initiation of communication, in which location information of a second device at which the second user has logged in is retrieved.

Abstract: A method of communication between two users using a system is claimed. Two communication devices are registered with at least one communication network and are capable of at least one communication type. A first user is allowed to connect to at least one communication network by using the first communication device. The first communication device is configured for wireless communication. From the first communication device, information indicating the location of the first user is sent to the system to enable the system to maintain a service record including the first user's location information. The first user is allowed to request communication by selecting an identifier for the second user from a list of displayed user identifiers. Location information from a service record is retrieved for the second communication device in response to the request. Communication of a selected type is initiated using the communication network and the retrieved address information.

The system is configured to enable multiple playbacks of media associated with the accessed media file.

Abstract: A system for real-time communication between a plurality of separated users is claimed. The system includes a record including associated location information of where a first user is logged in. Computer software causes display of a user identifier for a second user on the display of a communication device of the first user for selection by the first user.

Abstract: Two users are allowed to log in to respective first and second communication devices. The first and second communication devices are registered with at least one communication network. At least one communication network is a wireless network. Service records are maintained for the first and second communication devices. The service records include location information for the communication device at which the respective users have logged in. A user identifier for the second user is displayed in a list on the display of the first communication device. The first user is allowed to request communication with the second user by selecting the displayed identifier. Necessary location information of the second communication device is retrieved from a service record in response to the selection. The retrieved information is used to establish a connection between the first and second communication devices, thereby enabling real-time communication, including at least audio, between the two users.

Abstract: A communication system includes a call agent that coordinates and supervises communications between endpoints. The call agent allocates a QoS agent for each endpoint involved in a call. The QoS agents generate reservations for the call in order to provide the call with a guaranteed amount of bandwidth and an established QoS. Each endpoint or location associated with an endpoint has a reservation policy that determines how calls are to be handled when a reservation is or is not obtained and when a reservation is lost or obtained during a call. The communication system is able to handle reservations, or the lack thereof, during various situations like on hold, call transfer, call forwarding, conference call, and shared line services.

Abstract: An audio mixer on a first device receives one or more incoming audio streams. Each of the one or more incoming audio streams has an associated timestamp. The audio mixer generates a mixed audio stream from the one or more incoming audio streams. The audio mixer determines differences in the time base of each of the one or more incoming audio streams and the time base for the mixed audio stream. The audio mixer generates mapping parameters associated with the determined differences and transforms the timestamp of each of the one or more incoming audio streams to a corresponding output timestamp associated with the mixed audio stream according to the mapping parameters. the mapping parameters are provided to a video mixer for similar processing and transformation such that the mixed audio stream is in synchronization with a mixed video stream.

Abstract: A multimedia collaboration system has multimedia document marking and searching capabilities such that a user can rapidly access desired selected portions of stored multimedia documents. The mark and search feature can be context-based, content-based, time-based, or event based. The multimedia documents can be a collection of individual components in multiple media combined with an overall structure and timing component. The multimedia collaboration system itself 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.

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.
