Patent number: 8666047Abstract: Systems and methods that enable high quality audio teleconferencing are disclosed. In one embodiment of the present invention, a signal processor receives signals from a spatially dispersed set of directional microphones, processing the microphone signals and the far-end received audio into a signal for transmission to a far-end party. The processing may comprise the use of one or more algorithms that reduce conference room noise and may selectively increase participant audio levels by processing the microphone signals using beamforming techniques. An embodiment of the present invention may also comprise one or more omni-directional microphones that may be used in cooperation with the directional microphones to adjust for background noise, acoustic echo, and the existence of side conversations.Type: GrantFiled: March 12, 2007Date of Patent: March 4, 2014Assignee: Broadcom CorporationInventor: Darwin Rambo

Patent number: 8571854Abstract: One or more methods and systems of detecting or identifying one or more types of algorithms used in the encoding of a voice or speech waveform is presented. The system and method may be used as a testing tool to identify whether a voice data stream is encoded using a linear G.711, ?-law G.711, or A-law G.711 algorithm. The system and method are applied to a voice data stream to ensure that a codec with the appropriate algorithm is used to reproduce an audio waveform.Type: GrantFiled: December 29, 2008Date of Patent: October 29, 2013Assignee: Broadcom CorporationInventor: Darwin Rambo

Patent number: 8391175Abstract: Details of media encoding and decoding devices which support generic homing sequences, and methods for operating such devices are disclosed. The use of generic homing sequences may permit an embodiment of the disclosed invention to support real-time, bit-exact testing of existing and future media encoding and decoding devices. An embodiment of the present invention may permit the initialization of encoding and decoding algorithms to a known state, enabling bit-exact testing of a large group of devices using these algorithms, including those whose specifications do not support such functionality. This capability may permit the full-speed, bit-exact, testing, of both locally and remotely situated media encoders and decoders.Type: GrantFiled: August 9, 2010Date of Patent: March 5, 2013Assignee: Broadcom CorporationInventors: Darwin Rambo, Phil Houghton

Patent number: 8077848Abstract: Certain embodiments of the invention provides a method and system for 7-digit dialing in a 10-digit mandatory dialing area. Aspects of the invention may include collecting a dialed string of digits corresponding to a directory number for a dialed call and determining whether an area code should be pre-pended to the collected dialed string of digits. The area code may be transparently pre-pended to a 7-digit dialed directory number if it is determined that the call is for a local area in order to conform with mandatory 10-digit dialing. Otherwise, 10-digits may be collected and used to route the call.Type: GrantFiled: January 9, 2003Date of Patent: December 13, 2011Assignee: Broadcom CorporationInventor: Darwin Rambo

Patent number: 8073391Abstract: A device and method support dialup modem access over a wireless local area and/or personal area network such as, for example, an IEEE 802.11a/b/g/n and/or IEEE 802.15.3a network. A representative embodiment permits a user of a conventional Internet web browser application to access a dialup information provider via a switched telephone network, using the wireless network. A terminal adapter comprising a wired network interface and a wireless network interface receives messaging containing dialing information from a user of a personal computer, via the wireless network. The terminal adapter establishes a dialup connection to the information provider, and exchanges information between the personal computer and the information provider via the wired and wireless interfaces.Type: GrantFiled: July 13, 2010Date of Patent: December 6, 2011Assignee: Broadcom CorporationInventor: Darwin Rambo

Patent number: 8018853Abstract: Methods for using communication network statistics in the operation of a real-time communication system are disclosed. Embodiments of the invention may provide improved playback of real-time media streams by incorporating into the algorithms used for playback of the media stream network statistics typically calculated by some transport protocols. An additional aspect of the present invention may include machine-readable storage having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the foregoing.Type: GrantFiled: April 28, 2009Date of Patent: September 13, 2011Assignee: Broadcom CorporationInventors: Wilfrid LeBlanc, Darwin Rambo

Patent number: 7865361Abstract: One or more methods and systems of analyzing, assessing, and reporting voice quality scores are presented. In one embodiment, voice quality scores are generated by querying one or more computing devices responsible for processing a reference speech sample input into a voice communication system. In one embodiment, voice quality scores are transmitted by a voice analysis platform and subsequently analyzed. In one embodiment, a single voice analysis platform is used to measure voice quality of a voice communication system. In one embodiment, multiple voice analysis platforms are used to measure voice quality at multiple endpoints of one or more voice communication systems. In one embodiment, the method comprises a user determining one or more points along a communication system where transmitted reference speech samples are to be tapped. The tapped reference speech samples are ported to a voice analysis platform where a voice quality score is generated and graphically displayed.Type: GrantFiled: July 16, 2003Date of Patent: January 4, 2011Assignee: Broadcom CorporationInventors: Darwin Rambo, Philip Houghton

Publication number: 20100122109Abstract: Self-calibration of devices such as computer and graphics processors permits adjustment of processor clock rates, and access to normally unused processor capacity. Processor clock rates specified by device manufacturers are normally selected to insure operation across the entire manufacturer-specified range of operating temperatures and supply voltages. By limiting processor clock rates to nominal values, even when operating well within manufacturer-specified temperature and/or supply voltage limits, designers sacrifice processor capacity. By determining the upper limits of processor clock rates at which reliable operation can be realized, and adjusting processor clock rates to match those speeds, a representative embodiment of the present invention permits device users to gain additional, previously inaccessible processing capacity.Type: ApplicationFiled: January 19, 2010Publication date: May 13, 2010Inventors: Darwin Rambo, Philip Houghton
