Patent CA-2204442-C (CA)
Inventor: LAUWERS CHRIS J
IPC: H04N7/15
Filed: 1994-03-16
Granted: 1998-10-20
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 environment. 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.

Abstract: A circuit for training a trainable filter circuit having an adjustable time constant, the circuit having a clock generator operative to generate first and second clock signals on first and second clock signal outputs, respectively, of substantially the same amplitude and frequency. A first circuit has a reference filter circuit coupled to the first clock signal output and the second clock signal has the trainable filter circuit coupled to the second clock signal output. Means for adjusting one of the voltage input to and time constant of the reference circuit are provided. An amplifier coupled to an output of the reference circuit and to an output of the trainable filter circuit is operative to produce a DC output when the amplitudes of signals on the reference circuit output and the training circuit output are equal and an AC signal when they are unequal. A separator circuit coupled to an output of said amplifier is operative to rectify the AC signal and to subtract therefrom the DC signal and a feedback line couples an output of the separator circuit to the trainable filter circuit whereby an RC time constant of the trainable loop is modified until said AC signal is zero.

Title: Method of completing long distance pots calls with ip telephony endpoints
Inventor: RAMAMURTHY RAM S
IPC: H04M3/428
Filed: 1999-04-19
Granted: 2002-12-24
Abstract: When a calling party calls a called party on the public-switched telephone network (PSTN), a database common to both the PSTN and an Internet Protocol (IP) network, is accessed to determine whether the called telephone line is currently active on the IP network. That database maintains a record for each user who is currently active on the IP network through an Internet Service Provider (ISP). In addition, each record contains information identifying the particular user logged into the network on that line, an indication whether the telephone line is IP telephony capable, an indication whether that line is currently active on an IP telephony call on an Internet Telephony network (ITN), and the IP telephony feature set subscribed to by the called party on that line. If the telephone line is active, IP telephony capable, currently active on an IP . telephony call on the ITN, and the called party subscribes to a call waiting-on-IP feature, then the incoming call can be forwarded as an IP telephony call to the called telephone line over the ITN. Alternatively, the incoming call can be directed to an alternate destination on either the ITN network or the PSTN, such as a voice mail or message service. If the called party is engaged in a browsing activity and has an IP telephony capability, then the called party is alerted to the incoming telephone call via a message on his terminal. The incoming call is then completed through the ITN to the called party as an Internet telephony call.  If the called party is currently active on the IP network through an ISP, but does not have an IP telephony capability, then the PSTN forwards a message to the ISP, which pushes a message to the called party to inform him or her of the incoming call. The incoming call is then be directed onto the IP network to a messaging service, or on the PSTN to a voicemail service, or to an alternate telephone number, such as a cellular phone, for pickup by the called party.
