Patent number: 10367601Abstract: Control logic determines when a network condition has changed by evaluating network condition data. Based on a detected network condition change, the control logic reorders an encoder parameter controller execution sequence of a plurality of encoder parameter controllers. The control logic configures the plurality of reordered encoder parameter controllers so that an encoder parameter determination from a prior encoder parameter controller is used as a decision input for a subsequent encoder parameter controller. An encoder encodes data, such as audio data, video data or other type of data using the generated encoder control parameters from the reordered plurality of encoder parameter controllers. A related method is also disclosed.Type: GrantFiled: August 12, 2016Date of Patent: July 30, 2019Assignee: Google LLCInventors: Tina le Grand, Niklas Blum, Minyue Li, Henrik Lundin, Michael Tschumi, Alexander Narest

Patent number: 10290303Abstract: Computer-implemented techniques can include establishing, between first and second computing devices, an audio communication session via a network. The first computing device can receive and temporarily store audio packets corresponding to an audio input signal obtained by the second computing device. When the audio packets cause the buffer to fill beyond or at a rate exceeding a loss threshold indicative of a temporary loss of communication via the network, the techniques can decode the audio packets to obtain an audio output signal, determine whether the audio output signal includes speech, and when the audio output signal includes speech, remove a redundant portion of the audio output signal corresponding to a pitch period to obtain a modified audio output signal. The modified audio output signal can then be output via a speaker of the first computing device.Type: GrantFiled: August 25, 2016Date of Patent: May 14, 2019Assignee: Google LLCInventors: Serge Lachapelle, Henrik Lundin

Patent number: 10269371Abstract: A computer-implemented technique can include establishing an audio communication session between first and second computing devices and obtaining, by the first computing device, an audio input signal using audio data captured by a microphone. The first computing device can analyze the audio input signal to detect a speech input by its first user and can determine a duration of a detection period from when the audio input signal was obtained until the analyzing has completed. The first computing device can then transmit, to the second computing device, (i) a portion of the audio input signal beginning at a start of the speech input and (ii) the detection period duration, wherein receipt of the portion of the audio input signal and the detection period duration causes the second computing device to accelerate playback of the portion of the audio input signal to compensate for the detection period duration.Type: GrantFiled: September 29, 2017Date of Patent: April 23, 2019Assignee: Google LLCInventors: Erik Kay, Jonas Erik Lindberg, Serge Lachapelle, Henrik Lundin

Patent number: 6690311Abstract: Methods, systems, and arrangements enable true wide-band calibration of analog-to-digital conversion (ADC) using correction table indexing. The frequency of an analog input signal that corresponds to a digital output sample is accounted for, at least partially, when accessing a correction table during the creation and use thereof. For example, in addition to at least a portion of a current sample, at least portion(s) of previous and/or subsequent samples may be used to build (e.g., by bit concatenation) an index for addressing a correction table memory. In effect, compensation may be achieved for ADC errors that are frequency dependent. This correction table indexing may advantageously be employed along with a scheme that estimates one or more parameters of the analog input signal in the digital domain on a sample-by-sample basis in order to reconstruct the analog input signal in the digital domain.Type: GrantFiled: September 26, 2001Date of Patent: February 10, 2004Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Henrik Lundin, Peter Händel, Mikael Skoglund

Patent number: 6445317Abstract: A method, arrangement, and system enable adaptive calibration of an analog-to-digital converter (ADC) from reference signals with unknown parameter(s) that may vary (e.g., a varying frequency). An analog reference signal s(t) is supplied to an ADC to be calibrated. The output x(n) of the ADC is used by a, e.g., sine-wave reconstruction filter to reconstruct an estimate ŝ(n) of the sampled instances of the signal s(t). A recursive frequency estimator within the sine-wave reconstruction filter produces a frequency estimate of the analog reference signal s(t) from the signal x(n). An adaptive reconstruction filter uses this frequency estimate and the signal x(n) to produce the estimate ŝ(n). When a convergence detector determines that the adaptive reconstruction filter has converged, the estimate ŝ(n) is used to alter values that are stored in a correction table. During functional operation of the ADC, the correction table is used to correct the output values of the ADC.Type: GrantFiled: December 15, 2000Date of Patent: September 3, 2002Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Henrik Lundin, Peter Händel, Mikael Skoglund, Mikael Pettersson
