Publication number: 20110043601Abstract: A method which allows standard telephone users to audio conference with video conferencing participants over IP networks in a private secure environment. A dial-out is performed from one or more conference client terminals bridging audio between the Internet and the PSTN networks. The process uses a mixed mode hybrid network architecture for call set-up, initialization and teardown including the method to mix audio at the desktop terminal instead of in a general purpose server as in the prior art. The method conferences video and audio between multiple clients and include audio from a standard telephone network within the conference. A virtual private network connects all of the IP clients together including the voice over IP server used to transcode the proprietary audio into the H.323 standard for transport into the telephony network.Type: ApplicationFiled: December 23, 2009Publication date: February 24, 2011Applicant: MEETRIX CORPORATIONInventors: Thomas A.

Publication number: 20090016347Abstract: As prior art systems fail to produce end-to-end transport and routing mechanisms capable of secure, accurate, and timely delivery of real-time media, the present invention prescribes the method and process to facilitate server-less, IP based sessions across all of public and private network infrastructure without regard for network hardware or carrier makeup. The method and process claimed herein defines the application of well known standards in a unique fashion so as to facilitate transportation of TCP and UDP packets associated with a real-time multicast session in a secure manner while achieving unencumbered access through firewalls and across multiple carrier, public networks through IPSec based virtual networking.Type: ApplicationFiled: September 24, 2008Publication date: January 15, 2009Applicant: Meetrix CorporationInventors: L.

Publication number: 20040022322Abstract: A method and process used to improve the quality of multi participant video conferencing over Internet protocol which uses a unique feedback control loop to dynamically adjust for transport discrepancies commonly found in standard IP networks. The bit-rate of compressed video is adjusted by the limitation of data transport thru the network. Decimation of compressed objects represented by spatial and temporal sub bands of information during times of long latency or limited bandwidth are used to reduce the transmit bit-rate. Wavelet transforms are used for the derivation of spatial and temporal sub-band. Linear summation of decompressed sub-bands during the Inverse wavelet transform allows a quality of image based on the number of object or frame sub-bands received per given frame time. Error signals are developed based on the expected sub-band transport and the actual received number of sub-bands.Type: ApplicationFiled: July 16, 2003Publication date: February 5, 2004Applicant: Meetrix CorporationInventor: Thomas A.

Publication number: 20030235338Abstract: A method and process for improving the quality of multi participant video conferencing over Internet Protocol. The method uses a unique grayscale area map that represents objects in 3-D space to determine area boundaries and object priority for culling prior to transport. The method uses an objects depth map to determine the highest energy magnitude for motion estimation and compensation. By controlling the flow rate of objects over the temporal domain and the re-creation of object based predictive frames, a constant bit-rate scalable video compression algorithm has been shown. Spatial and temporal hierarchical significance trees are used to build maps of significant energy on a per-object basis. Thus, the bit-rate of compressed video is dynamically adjusted by the limitation of data transport through the network.Type: ApplicationFiled: May 28, 2003Publication date: December 25, 2003Applicant: Meetrix CorporationInventor: Thomas A.
