    摘要: The present invention is directed to a system, including apparatus and architecture, and method for providing scheduled and ad hoc voice over IP conference services having enhanced quality and reliability. The system uses an overlay network of geographically distributed conference servers working simultaneously and collaboratively to host a given conference session. Multiple conference servers simultaneously and collaboratively perform the necessary audio mixing. The voice routing path is established and controlled within the overlay network and supports conference services across different conference service providers.

    摘要: A system and method for establishing a private message chat between electronic devices. The method includes steps of providing an indication as to the availability of a user for receiving a private message chat; receiving an audio input message from at least one first client; and transmitting the audio input message to at least one second client over a communications network, wherein the at least one second client can receive, temporarily store and play back the audio input message. The first client may receive a reply audio input message from the at least one second client or, receive a reply text input message from the at least one second client, and subsequently may further communicate back to the second client device via one of audio or text messaging, according to that user's discretion. The transmitting of any audio input message may be accomplished via VoIP or SIP.

    摘要: A system, method, and computer program product for establishing multi-party VoIP conference audio calls in a distributed, peer-to-peer network where any number of nodes are able to arbitrarily and asynchronously start or stop producing audio output to be mixed into a single composite audio stream that is distributed to all nodes. A single distribution tree is used that has optimal communications characteristics to distribute the composite audio signal to all nodes. An audio mixing tree is established and maintained by adaptively and dynamically adding and merging intermediate mixing nodes operating between user nodes and the root of the single distribution tree. The intermediate mixing nodes and the root of the single distribution tree are all hosted, in an exemplary embodiment, on user nodes that are endpoints of the distribution tree.

    摘要: Projector and camera arrangements are provided for use in electronic whiteboard systems. Specifically, the present invention provides projector and camera arrangements wherein the projector and camera share the same imaging optics. By sharing the same projection and camera optics, the distortions that affect the projection system are the same as those of the camera system. Thus, the calibration step required in conventional whiteboard systems where the projector and camera are separate, i.e., each having their own distinct optics and settings, is no longer needed. Further, the arrangements provided in accordance with the invention are self-aligning, even when lens distortions are large and even in the presence of strong perspective effects. The shared optics projector and camera arrangements of the invention also provide for dynamic zooming. In addition, various active and passive optical marker or lightpen designs are provided for use in electronic whiteboard systems.

    摘要: A method and apparatus for compressing video data to improve its tolerance to error, especially with a low bit rate network. With this invention video data is divided into a number of frames and each frame is divided into a number of macroblocks. A dependency count is assigned to each macroblock, and if the dependency count for the macroblock exceeds or is equal to a threshold, the dependency block is intra-coded using low bit rate coding algorithm. If the dependency count is below the threshold, the macroblock is inter-coded.

    摘要: A framework is provided to offer composite voice applications and services. A composite application and service begins from the user dialing in via phone and ends by the user hanging up the phone. The composite interactive voice services architecture includes a session initiation protocol session service unit is in the loop of session signaling all the time starting from the time the user first dials in, during the user roaming across various voice servers, and until the end of the composite service when user hangs up the phone. This unit accepts a command and login instruction of the next interactive voice service from the previous interactive voice service. The unit has knowledge of DTMF sequences required for the user to login to next interactive voice service. The session service unit automatically accomplishes a roaming process such that composite applications and services can be achieved across various voice servers.

    摘要: An n-ways conferencing system using only the participants' telephony devices and without an external conference server. A plurality of telephony devices dial in to and report their mixing capability to a connection topology manager. The connection topology manager also determines the location of each telephony device and neighboring telephony device pairs in the conference service, as each telephony device is used for mixing voice signals of its closest neighbors, and calculates a minimum conference traffic delay for each telephony device. The connection topology manager then builds a topology for the conference service based on the mixing capability, location, and minimum conference traffic delay, wherein the connection topology manager distributes a mixing computation in a substantially uniform manner across the plurality of telephony devices. When a change in the network condition is detected, the connection topology manager rebuilds the topology to bypass the change in the network condition.
