Patent number: 9258411Abstract: There is a need for a forensic diagnostic capability to facilitate a greater understanding of why xDSL transceivers are subject to otherwise inexplicable service interruptions during Showtime (steady state data transmission mode). In certain exemplary embodiments, diagnostic data from a previous Showtime is stored and then communicated to another transceiver and/or reported (or communicated) to a management entity. The stored diagnostic data can be used to determine why the service interruption occurred. In other embodiments, one or more portions diagnostic data from a last Showtime are stored. In additional embodiments, this diagnostic data is collected immediately prior to exiting Showtime and/or retraining (the “last” data collected prior to exiting Showtime and/or retraining).Type: GrantFiled: November 4, 2010Date of Patent: February 9, 2016Assignee: BROADCOM CORPORATIONInventors: Marcos C.

Publication number: 20160037416Abstract: Embodiments provide a method, apparatus and computer program for operating a user equipment (UE). The method beings by determining that a valid authentication for the UE, generated with a radio network operating with a first radio access technology (RAT), is not a mutual authentication between the UE and the network operating with the first RAT. In response, the UE unilaterally takes action to prevent the valid authentication that is not a mutual authentication from being used to authenticate with a radio network operating with a second RAT that utilizes mutual authentication.Type: ApplicationFiled: October 12, 2015Publication date: February 4, 2016Applicant: Broadcom CorporationInventors: Matti Tapani MOISANEN, Marko Tapani Akselin, Marko Tapani Niemi

Publication number: 20160037171Abstract: Multi-mode error concealment, recovery and resilience coding. Adaptation of a number of coding units (CUs) employed in accordance with video coding may be made as a function of error. As a number of errors increases, the respective number of CUs may correspondingly increase (e.g., which may be made in accompaniment with a reduction of CU size). As a number of errors decreases, the respective number of CUs may correspondingly decrease (e.g., which may be made in accompaniment with an increase of CU size). Such errors may be associated with a type of source providing a video signal, a type of error resilience coding employed, communication link and/or channel conditions, a remote error characteristic (e.g., such as associated with a source device and/or destination device), a local error characteristic (e.g., such as associated with operations and/or processing within a given device), and/or any other type of consideration.Type: ApplicationFiled: October 9, 2015Publication date: February 4, 2016Applicant: BROADCOM CORPORATIONInventors: Brian Heng, Wade K.

Patent number: 9253532Abstract: A participation device in a multiparty conference call may act as a server device and/or a client device for two-way audio and video (AV) streaming. A server device may encode a requested AV stream into a set of different encoding profiles that may be dynamically determined based on the varying channel conditions and device capacities of the client devices. At least a portion of differently encoded AV streams is selected and dynamically communicated to the client devices for display. Session parameters are determined according to the varying channel conditions and the device capacities of the client devices to create intended sessions. The selected encoded AV streams are communicated utilizing segment-based adaptive streaming techniques such as HTTP. A client device may access to a HTTP session to download an expected AV stream from the server device. The downloaded AV stream may be decoded into different decoding profiles for display as needed.Type: GrantFiled: October 14, 2014Date of Patent: February 2, 2016Assignee: BROADCOM CORPORATIONInventors: Xuemin Chen, Yong Li, Arlen J.

Patent number: 9253743Abstract: Systems and methods are described for reducing latency and improving beacon reception by a device capable of providing multiple wireless interfaces via a single radio (a “multi-interface device”). The multi-interface device utilizes the single radio to communicate with a first device over a first wireless channel and to communicate with a second device over a second wireless channel. The multi-interface device determines that a difference in time between a transmission of a first beacon by the first device over the first wireless channel and a transmission of a second beacon by the second device over the second wireless channel is less than a predetermined amount of time. In response to determining that the difference in time is less than the predetermined amount of time, the multi-interface device sends a request to either the first or the second device to shift the transmission of future beacons by a requested offset time.Type: GrantFiled: June 27, 2013Date of Patent: February 2, 2016Assignee: Broadcom CorporationInventors: Sushant Kumar Mishra, Jayaraman Nagarajan, Gireesh Hegde, Rakesh Raman

Patent number: 9253568Abstract: A technique for suppressing non-stationary noise, such as wind noise, in an audio signal is described. In accordance with the technique, a series of frames of the audio signal is analyzed to detect whether the audio signal comprises non-stationary noise. If it is detected that the audio signal comprises non-stationary noise, a number of steps are performed. In accordance with these steps, a determination is made as to whether a frame of the audio signal comprises non-stationary noise or speech and non-stationary noise. If it is determined that the frame comprises non-stationary noise, a first filter is applied to the frame and if it is determined that the frame comprises speech and non-stationary noise, a second filter is applied to the frame.Type: GrantFiled: May 14, 2010Date of Patent: February 2, 2016Assignee: Broadcom CorporationInventors: Elias Nemer, Wilfrid LeBlanc, Syavosh Zad-Issa, Jes Thyssen

Patent number: 9252809Abstract: Serializer-Deserializer (SerDes) operation is optimized for signals based on signal error statistics. Forward Error Correction (FEC) may provide feedback of error statistics or error correction statistics to a SerDes tuner, which uses the statistics to selectively tune or adjust SerDes operating parameters, such as vertical and horizontal sampling or slicing offsets, gain and equalization, to decrease the bit error rate (BER). Statistics report which bits and patterns are corrected and to what values. Knowledge of expected and actual signals is leveraged to correlate detected errors with underlying problems and solutions to optimize SerDes operation. Each node in a network, such as a Ethernet Passive Optical Network (EPON), is enabled to fine tune its operation independently for each logical or physical channel.Type: GrantFiled: October 11, 2012Date of Patent: February 2, 2016Assignee: Broadcom CorporationInventor: Ryan Hirth
