Patent number: 7733848Abstract: In order to enable V.34 fax relay communications over IP (“FoIP”) without increasing a gateway complexity, the gateway relays all types of fax control signals in demodulated form and transfers fax image type signals either as demodulated or as PCM encoded signal, based on a predetermined condition. The PCM data type is added to FoIP protocol to allow transferring PCM encoded fax image signals without exiting from FoIP mode of operation until the completion of a fax call. During a FoIP call, the communicating gateway determines whether the input fax signal is a ‘fax control signal’ or a ‘fax image’ type signal. If the gateway determines that the input signal is a fax control signal or supported fax image signal, it handles it in a traditional fax relay manner. However, if the gateway determines that the input fax image type signal cannot be demodulated, it outputs the fax signal to the IP network as PCM encoded signal and without performing demodulation.Type: GrantFiled: May 25, 2005Date of Patent: June 8, 2010Assignee: AudioCodes Ltd.Inventor: Vladimir Ulybin

Publication number: 20030128403Abstract: The invention relates to a method of detecting a watermark W, formed by a set of coefficients, in an information signal S, said watermark W and said information signal S being configured in the form of matrices SM M*M. The coefficients of the Fourier transform matrix of the matrix of the signal TSM and the coefficients of the Fourier transform matrix of the watermark matrix TWM are used in a calculation step CAL of the inverse transform matrix of the multiplication ITM of the transform matrix of the signal TSM and of the transform matrix of the watermark TWM, said calculation CAL being produced in sequences which each result in obtaining I columns of the inverse transform matrix of the multiplication, where M is a multiple of I and different from I. Said I columns are stored in a memory called internal memory and the detection step DET of the watermark is achieved with each sequence by detection of peaks of each set of the I columns while said I columns are present in the internal memory.Type: ApplicationFiled: December 17, 2002Publication date: July 10, 2003Inventors: Hugues De Perthuis, Eric Desmicht

Patent number: 6522424Abstract: An image data transfer system and method enable scan time and transfer time of the image data to be adjusted appropriately without lacking a part of the image data, suitable for low price. A data segmentation device segments the image data from a scan device into high order n bits and low order (N−n) bits, subsequently, transferring the high order n bits toward a data transfer device at the same time when the scan device scans a manuscript, and transferring the low order (N−n) bits toward a memory device. The data transfer device transfers the high order n bits of the image data toward a personal computer at the same time when the scan device scans the manuscript. The memory device stores therein the low order (N−n) bits of the image data temporarily. Furthermore, the data transfer device scans the low order (N−n) bits of the image data from the memory device to transfer toward the personal computer after transfer of the high order n bits.Type: GrantFiled: February 10, 1999Date of Patent: February 18, 2003Assignee: Nec CorporationInventors: Kouji Nakahara, Tetsuichirou Yamamoto

Patent number: 6483600Abstract: A system and method for communicating a facsimile reliably in real-time without using bandwidth inefficiently. A facsimile signal is created at a transmitting facsimile device and communicated to a transmitting gateway. The transmitting gateway demodulates the facsimile signal by using the modulation data rate at which the facsimile signal was sent. The image and any control information, with the exception of the DCS signal, are left coded such that processing time is not wasted on decoding the image. The facsimile signal is packetized and sent over the data network, such as the Internet. The facsimile signal is sent to a receiving gateway closest to the facsimile device that is the destination of the facsimile.Type: GrantFiled: February 26, 1999Date of Patent: November 19, 2002Assignee: 3Com CorporationInventors: Guido M. Schuster, Richard G. McCallister, Sean Fendt

Patent number: 6438105Abstract: A reliable facsimile transmission protocol and method for transmission of facsimile data over an IP network such as the Internet. The protocol features error correction through the use of a retransmission of packets with a flow-control window and a dynamic redundancy window which alters the number of redundant frames that are transmitted in the packet. The size of the dynamic redundancy window expands or contracts depending on the behavior and quality of the IP network, for example whether it exhibits choppy, error-causing characteristics.Type: GrantFiled: February 8, 1999Date of Patent: August 20, 2002Assignee: 3Com CorporationInventors: Khwaja F.
