Publication number: 20130282820Abstract: A method for optimizing a multiparty multimedia conferencing communication session over communications networks is provided. A host multimedia stream is received from a host multimedia client. A first element indicative of presence of a multimedia conferencing session is transmitted to participating multimedia clients by the host multimedia client. Subsequently, individual multimedia streams are received from participating multimedia clients. The host multimedia stream is processed and transmitted to the participating clients. A second element indicative of presence of the multimedia conferencing session is transmitted by the participating clients to the host multimedia client and to each other. The individual multimedia streams are processed separately and transmitted to the host multimedia client and to the participating multimedia clients.Type: ApplicationFiled: April 23, 2013Publication date: October 24, 2013Applicant: OnMobile Global LimitedInventors: Marwan A.

Patent number: 7996217Abstract: An apparatus for processing adaptive codebook pitch lag from one CELP based standard to another CELP based standard. The apparatus has various modules that perform at least the functionality described herein. The apparatus includes a time-base subframe checker inspection module, which is adapted to associate one or more incoming subframes with an outgoing subframes of a destination codec. The apparatus also has a decision module coupled to the time-base subframe inspection module. The decision module is adapted to determine a desired pitch lag parameter from a plurality of pitch lag parameters among respective two or more incoming subframes. The apparatus has a pitch lag selection module coupled to the decision module. The pitch lag selection module is adapted to select the desired pitch lag parameter.Type: GrantFiled: July 26, 2007Date of Patent: August 9, 2011Assignee: OnMobile Global LimitedInventors: Marwan A.

Publication number: 20070025546Abstract: A method and apparatus for DTMF detection and voice mixing in the code-excited linear prediction (CELP) parameter space, without fully decoding and reconstructing the speech signal. The apparatus includes a Dual Tone Multiplexed Frequency (DTMF) signal detection module and a multi-input mixing module. The DTMF signal detection module detects DTMF signals by computing characteristic features from the input CELP parameters and comparing them with known features of DTMF signals. The multi-input mixing module mixes multiple sets of input CELP parameters, that represent multiple voice signals, into a single set of CELP parameters. The mixing computation is performed by analyzing each set of input CELP parameters, determining the order of importance of the input sets, selecting a strategy for mixing the CELP parameters, and outputting the mixed CELP parameters.Type: ApplicationFiled: September 19, 2006Publication date: February 1, 2007Applicants: Dilithium Networks Pty Ltd., Macchina Pty Ltd.Inventors: Marwan Jabri, Jianwei Wang, Sameh Georgy, Michael Ibrahim

Publication number: 20050258983Abstract: Method and apparatus for trans-rating a bitstream of data through multi-rate voice coders converting a bitstream representing frames of data encoded according to a first voice compression method of a first rate to a second voice compression method according to a second rate. A trans-rating pair includes voice compression parameters mapping modules. The method of trans-rating includes either bit-unpacking or unquantization on an encoded packet at input site to obtain rate information and voice compression parameters according to the first rate voice compression method. The information of the first rate and the required output rate, namely a second rate type, in addition to external control commands, are then used to determine the converting strategy of the trans-rating pair. Next, at least some of the compression parameters of the first rate are passed through, or mapped, into compression parameters of the second rate compatible with the second rate voice compression method.Type: ApplicationFiled: May 11, 2004Publication date: November 24, 2005Applicant: Dilithium Holdings Pty Ltd.
