Patent number: 8078456Abstract: A modified synchronized overlap add (SOLA) algorithm for performing high-quality, low-complexity audio time scale modification (TSM) is described. The algorithm produces good output audio quality with a very low complexity and without producing additional audible distortion during dynamic change of the audio playback speed. The algorithm may achieve complexity reduction by performing the maximization of normalized cross-correlation using decimated signals. By updating the input buffer and the output buffer in a precise sequence with careful checking of the appropriate array bounds, the algorithm may also achieve seamless audio playback during dynamic speed change with a minimal requirement on memory usage.Type: GrantFiled: May 12, 2008Date of Patent: December 13, 2011Assignee: Broadcom CorporationInventors: Juin-Hwey Chen, Robert W.

Patent number: 8045482Abstract: A system and method is described for constructing a proximity-based ad hoc network among a plurality of sensors and for using such a network to perform location tracking. The system and method uses time-coded data received from each of the sensors to determine a current proximity of each of the sensors to one or more beacons. Then, by leveraging information relating to the effective transmission ranges of the beacons, the system and method determines the relative location of each of the plurality of sensors with respect to other sensors within the plurality of sensors. Where actual (as opposed to relative) location information is available for a particular sensor, it can be used to generate or augment location information associated with other sensors known to be spatially and temporally proximate to the particular sensor. The current location information for each of the sensors is then used in providing location-based services.Type: GrantFiled: February 8, 2008Date of Patent: October 25, 2011Assignee: Yahoo!

Patent number: 8041562Abstract: A technique is described herein for reducing audible artifacts in an audio output signal generated by decoding a received frame in a series of frames representing an encoded audio signal in a predictive coding system. In accordance with the technique, it is determined if the received frame is one of a predefined number of received frames that follow a lost frame in the series of the frames. Responsive to determining that the received frame is one of the predefined number of received frames, at least one parameter or signal associated with the decoding of the received frame is altered from a state associated with normal decoding. The received frame is then decoded in accordance with the at least one parameter or signal to generate a decoded audio signal. The audio output signal is then generated based on the decoded audio signal.Type: GrantFiled: May 29, 2009Date of Patent: October 18, 2011Assignee: Broadcom CorporationInventor: Jes Thyssen

Patent number: 8024192Abstract: A technique is described for use in a decoder configured to decode a series of frames representing an encoded audio signal. The technique is for transitioning between a lost frame and one or more received frames following the lost frame in the series of frames. In accordance with the technique, an output audio signal associated with the lost frame is synthesized. An extrapolated signal is generated based on the synthesized output audio signal. A time lag is calculated between the extrapolated signal and a decoded audio signal associated with the received frame(s), wherein the time lag represents a phase difference between the extrapolated signal and the decoded audio signal. The decoded audio signal is time-warped based on the time lag, wherein time-warping the decoded audio signal comprises stretching or shrinking the decoded audio signal in the time domain.Type: GrantFiled: August 15, 2007Date of Patent: September 20, 2011Assignee: Broadcom CorporationInventors: Robert W.

Patent number: 8015000Abstract: An audio decoding system performs frame loss concealment (FLC) when portions of a bit stream representing an audio signal are lost within the context of a digital communication system. The audio decoding system employs two different FLC methods: one designed to perform well for music, and the other designed to perform well for speech. When a frame is deemed lost, the audio decoding system analyzes a previously-decoded audio signal corresponding to previously-decoded frames of an audio bit-stream. Based on the results of the analysis, the lost frame is classified as either speech or music. Using this classification, other signal analysis, and knowledge of the employed FLC methods, the audio decoding system selects the appropriate FLC method which then performs FLC on the lost frame.Type: GrantFiled: April 13, 2007Date of Patent: September 6, 2011Assignee: Broadcom CorporationInventors: Robert W.

Patent number: 8010350Abstract: A method and system for refining an estimated pitch period estimate based on a coarse pitch useful for performing frame loss concealment in an audio decoder as well as for other applications. A normalized correlation at the coarse pitch lag is computed and used as the current best candidate. The normalized correlation is then evaluated at the midpoint of the refinement pitch range on either side of the current best candidate. If the normalized correlation at either midpoint is greater than the current best lag, the midpoint with the maximum correlation is selected as the current best lag. After each iteration, the refinement range is decreased by a factor of two and centered on the current best lag. This bisectional search continues until the pitch has been refined to an acceptable tolerance or until the refinement range has been exhausted. During each step of the bisectional pitch refinement, the signal is decimated to reduce the complexity of computing the normalized correlation.Type: GrantFiled: April 13, 2007Date of Patent: August 30, 2011Assignee: Broadcom CorporationInventor: Robert W.

Patent number: 8005678Abstract: A technique is described herein for updating a state of a decoder configured to decode a series of frames representing an encoded audio signal. In accordance with the technique, an output audio signal associated with a lost frame in the series of frames is synthesized. The decoder state is set to align with the synthesized output audio signal at a frame boundary. An extrapolated signal is generated based on the synthesized output audio signal. A time lag is calculated between the extrapolated signal and a decoded audio signal associated with a first received frame after the lost frame in the series of frames, wherein the time lag represents a phase difference between the extrapolated signal and the decoded audio signal. The decoder state is then reset based on the time lag.Type: GrantFiled: August 15, 2007Date of Patent: August 23, 2011Assignee: Broadcom CorporationInventors: Robert W.

Patent number: 8005774Abstract: Methods, systems, and apparatuses for generating relevance functions for ranking documents obtained in searches are provided. One or more features to be used as predictor variables in the construction of a relevance function are determined. The relevance function is parameterized by one or more coefficients. An ideal query error is defined that measures, for a given query, a difference between a ranking generated by the relevance function and a ranking based on a training set. According to a structured output learning framework, values for the coefficients of the relevance function are determined to substantially minimize an objective function that depends on a continuous upper bound of the defined ideal query error. The query error is determined using a structured output learning technique. The query error is defined as a maximum over a set of permutations.Type: GrantFiled: November 28, 2007Date of Patent: August 23, 2011Assignee: Yahoo! Inc.Inventor: Olivier Chapelle
