FIG. 1 depicts an exemplary block diagram of a conferencing system in accordance with one embodiment of the present invention.
Reference is now made to FIG. 1, which depicts an exemplary block diagram of a conferencing system 10 in accordance with the principles of the present invention. The system comprises a plurality of conference endpoints 12 and 14. Each of the endpoints 12 and 14 can call and be called. Each of the endpoints 12 and 14 generates and/or terminates information streams. Each of the endpoints 12 and 14 comprises a control module. In accordance with the present invention, a local endpoint can control one or more functions of a remote endpoint by using control signals according to a certain protocol. Conversely, one or more functions of the local endpoint can be controlled by the remote endpoint by using control signals according to a certain protocol.
One or more of the endpoints 12 and 14 may comprise an analog phone coupled to an adapter unit. The adapter unit is connected in series with the analog phone. The adapter unit may be connected to the network 16 via POTS connection, or an IP connection, or a modem connection, etc. In accordance with certain embodiments of the present invention, the adapter unit enables the endpoint 12 to embed a control signal in an outgoing audio signal, according to a low profile signaling protocol, as discussed further herein. The adapter unit can also extract and decode a control signal from an incoming audio signal according to a low profile signaling protocol.
One or more of the endpoints 12 and 14 may also comprise a video conferencing unit (“VCU”). A VCU transmits, receives, and processes video images as well as audio signals. A VCU typically comprises a video processing component and an audio processing component. The video processing component may include a camera to capture live images of conference participants, and a video display for showing real-time video images of conference participants or images of documents. The audio processing component of a video conferencing unit may include one or more microphones and one or more loudspeakers. In one embodiment, for example, the endpoint 12 and/or the endpoint 14 of FIG. 1 may be embodied as the VCU depicted in FIG. 3 or may include an ISDN interface in place of the IP interface.
As another example, the control signals may include instructions for the bridge to dial a specific phone number, connect to a specific IP address or use other dialing information to connect another party. In this manner, a conferee may be added to a conference call. Advantageously, by having the bridge call a participant instead of having the participant call the bridge, the participant need not remember any particular dialing information or passwords to join a conference. The dialing information can be in different format for different connections. The dialing information can be phone numbers, E.164 strings which are strings for dialing international phones, IP addresses or SIP addresses etc. Such information can be difficult to remember. For example, phone numbers, conference ID numbers can be long strings of numbers. An international phone number alone can be up to 15 digits long. Other dialing information, such as IP addresses, or an SIP (Session Initiation Protocol) address (URIs, Uniform Resource Indicator), can be even more complicated,
In the situation where each speakerphone is connected to a videoconferencing unit, such as by an HSSB link described below, the new connection can be a video link between the two videoconferencing units. Speakerphone A is linked to videoconferencing unit A and speakerphone B is linked to videoconferencing unit B. Participant A elects to migrate the conference between Participants A and B from audio only to video and audio. Participant A selects this function on speakerphone A. Speakerphone A retrieves the dialing information such as a telephone number or an IP address, or both, from videoconferencing unit A. This information is then transmitted to speakerphone B in a message that says “Have your video unit call mine at 123-456-7890.” Speakerphone B receives the message and provides the request and number or numbers to videoconferencing unit B. Videoconferencing unit B then initiates the videoconference to complete the connection. This is an example of commands being transferred among various units in a chain to perform the desired operation.
Similarly, during a video conference, a video conference unit may have a phone number of another party for an audio conference. Video conference unit A may send the phone number to speakerphone A which is connected to video conference unit A via a conference link, such as an HSSB link. Speakerphone A can then dial the phone number and set up an additional audio conference with that party. The phone number could be previously stored in Video conference unit A; it could be received by video conference unit A from a far end video conference unit B during the video conference call, which in turn may have received it from a similarly connected speakerphone B; or it could be supplied by other methods. In the process of setting up the video conference or the audio conference, user involvement is minimal.
In one embodiment of the present invention, the network 16 of FIG. 1 (and/or any of the networks 27, 28, and 29 of FIG. 2) may be an IP-based network. The network may comprise a packet switched IP-based network such as a local area network (LAN) utilizing, for example, Ethernet technology, or a wide area network (WAN) such as the Internet. Devices communicating through an IP-based network employ an appropriate communication standard and an appropriate protocol such as Transmission Control Protocol/Internet Protocol (TCP/IP).
Reference is now made to FIG. 3, which depicts an exemplary conferencing system 100 employing an IP-based protocol in accordance with one embodiment of the present invention. One or more of the endpoints 12 and 14 of FIG. 1 or one or more of the endpoints 24, 25, and 26 of FIG. 2 may be embodied as the endpoint 102 shown in FIG. 3. Although the endpoint 102 is depicted and described as a video conferencing unit, it will be appreciated by those of skill in the art that the video capability is optional, and the endpoint 102 may alternatively be a device for audio conferencing without video conferencing capability.
The endpoint 12 of FIG. 1 may be embodied as the local endpoint 600 of FIG. 6A, and the endpoint 14 of FIG. 1 may be embodied as the remote endpoint 601 of FIG. 6B. Any of the endpoints 24, 25, and 26 of FIG. 2 may be embodied as the local endpoint 600 or the remote endpoint 601 of FIGS. 6A and 6B.
As discussed herein, the carrier signal modulator/demodulator 608 can also demodulate incoming modulated carrier signals. Once the digital data has been extracted from the incoming modulated carrier signal by the carrier signal modulator/demodulator 608, the digital data is forwarded to a local data management engine 614. An exemplary embodiment of a data management engine is shown in FIG. 6C. Although the perspective from the local endpoint 600 or the remote endpoint 601 is utilized at certain parts of this discussion for purposes of simplicity, the local endpoint 600 and the remote endpoint 601 are capable of performing identical or similar functions, due to the bidirectional nature of communication, in accordance with the present invention.
