A packet-based, hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. The network accommodates real time voice transmission both through dedicated, scheduled bandwidth and through a packet-based routing within the confines and constraints of a data network. Conversion and call processing circuitry is also disclosed which enables access devices and personal computers to adapt voice information between analog voice stream and digital voice packet formats as proves necessary. Routing pathways include wireless spanning tree networks, wide area networks, telephone switching networks, internet, etc., in a manner virtually transparent to the user. A voice session and associate call setup simulates that of conventional telephone switching network, providing well-understood functionality common to any mobile, remote or stationary terminal, phone, computer, etc.

Hierarchical Data Collection Network Supporting Packetized Voice Communications Among Wireless Terminals and Telephones

A method is provided in one example embodiment and includes receiving data indicative of a personal position of an end user and receiving image data associated with an object. The image data can be captured by a first camera at a first angle and a second camera at a second angle. The method also includes synthesizing the image data in order to deliver a three-dimensional rendering of the object at a selected angle, which is based on the data indicative of the personal position of the end user. In more specific embodiments, the synthesizing is executed by a server configured to be coupled to a network. Video analytics can be used to determine the personal position of the end user. In other embodiments, the method includes determining an approximate time interval for the synthesizing of the image data and then delaying audio data based on the time interval.

System and method for providing three dimensional imaging in a network environment

A method is provided in one example and includes capturing panoramic image data through a first camera in a camera cluster, and capturing close-up image data through a second camera included as part of a spaced array of cameras. The presence of a user in a field of view of the second camera can be detected. The close-up image data and the panoramic image data can be combined to form a combined image. In more specific embodiments, the detecting includes evaluating a distance between the user and the second camera. The combined image can reflect a removal of a portion of panoramic image data associated with the user in a video conferencing environment.

System and method for providing depth adaptive video conferencing

Systems and methods by which voice/data communications may occur in multiple modes/protocols are disclosed. In particular, systems and methods are provided for multiple native mode/protocol voice and data transmissions and receptions with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus, and multi-protocol framing engines. Such systems preferably include subsystem functions such as PBX, voice mail and other telephony functions, LAN hub and data router. In preferred embodiments, a TDM bus and a packet bus are intelligently bridged and managed, thereby enabling such multiple mode/protocol voice and data transmissions to be intelligently managed and controlled with a single, integrated system. A computer or other processor includes a local area network controller, which provides routing and hub(s) for one or more packet networks. The computer also is coupled to a buffer/framer, which serves to frame/deframe data to/from the computer from TDM bus. The buffer/framer includes a plurality of framer/deframer engines, supporting, for example, ATM and HDLC framing/deframing. The buffer/framer is coupled to the TDM bus by way of a switch/multiplexer, which includes the capability to intelligently map data traffic between the buffer/framer and the TDM bus to various slots of the TDM frames. Preferably, a DSP pool is coupled to buffer/framer in a manner to provide various signal processing and telecommunications support, such as dial tone generation, DTMF detection and the like. The TDM bus is coupled to a various line/station cards, serving to interface the TDM bus with telephone, facsimiles and other telecommunication devices, and also with a various digital and/or analog WAN network services.

A system and method for alerting participants in a videoconference that one or more participants are improperly framed by the videoconference camera is provided. An embodiment comprises a temporary self-view picture-in-picture image appearing when the number of faces detected by the videoconference camera changes. A face detection algorithm is used to determine when the number of faces being detected by the videoconference camera has changed. The self-view picture-in-picture image displays, for a duration of time, a representation of the image being captured by the videoconference camera, allowing participants who are not properly framed by the videoconference camera to adjust their position to that their faces are captured by the videoconference camera.

Adaptive quantization for uniform quality in panoramic videoconferencing

A Multiservice Access Concentrator (MAC) receives a called number and matches the number against a destination-pattern index. A logical group of single access telephone numbers are associated to at least one voice port, wherein a logical group of candidate voice ports are formed. The logical group of candidate voice ports are sorted to form a sorted table. The sorting comprises using a prioritized sort criteria, wherein the sort criteria comprises sorting by explicit preference, longest telephone number match metric, local voice ports taking priority over network voice ports, administrative metrics of the network voice ports, time-of-last-use timestamp, and predefined order. Hunting for a voice port among a logical group of candidate voice ports is performed, wherein the logical group of candidate voice ports is distributed across at least one voice over packet-data-network system (VOPS). The VOPS comprises voice over Internet Protocol (IP) network systems, voice over Frame Relay network systems, voice over Asynchronous Transfer Mode (ATM) network systems, and voice over High-level Data Link Control (HDLC) network systems, but the embodiment is not so limited. Ringing of a telephone extension coupled to the voice port is performed.

Method and apparatus for voice port hunting of remote telephone extensions using voice over packet-data-network systems (VOPS)

A method and apparatus for link state determination in voice over frame-relay networks. In one embodiment, the present invention includes a method for determining link state for permanent calls in an FRF.11 voice over data network at the virtual voice channel level. This is a capability not present in FRF.11, which includes a management mechanism for determining link state of virtual circuits, but no mechanism for determining link state of virtual channels. One embodiment uses a standard FRF.11 signaling frame with a status indicator bit to signal that a channel is a primary operative channel or an alternate operative channel. The signaling frames are sent end to end through the network by an initiator device along a primary data path and all alternate data paths. If a primary or alternate path is operative, a reciprocator device returns the signaling frame along the operative path. The initiator determines by receipt or non-receipt of the signaling frames which paths are operative at any time. This allows the initiator to quickly detect primary path failure and switch to an operative alternate path.
