20100115370 | METHOD AND APPARATUS FOR ERROR CONCEALMENT OF ENCODED AUDIO DATA - A method of frame error concealment in encoded audio data comprises receiving encoded audio data in a plurality of frames; and using saved one or more parameter values from one or more previous frames to reconstruct a frame with frame error. Using the saved one or more parameter values comprises deriving parameter values based at least part on the saved one or more parameter values and applying the derived values to the frame with frame error. | 05-06-2010 |
20150287418 | METHOD AND APPARATUS FOR RESILIENT VECTOR QUANTIZATION - It is inter alia disclosed to quantise a vector of a plurality of coefficients using a predictive mode of operation of a vector quantiser, wherein the vector quantiser can operate in either a predictive mode of operation or a non-predictive mode of operation, determine a vector of a plurality of recovered coefficients; compare the vector of the plurality of coefficients to the vector of the plurality of recovered coefficients; and determine the mode of operation of the vector quantiser for a vector of a plurality of coefficients associated with a subsequent frame of audio samples, wherein the mode of operation is dependent on the comparison. | 10-08-2015 |
20150332677 | AUDIO CODEC MODE SELECTOR - There is inter alia a method comprising: receiving a request to change the coding rate of a multimode audio codec; determining that the request corresponds to a coding rate of another mode of operation of the multimode audio codec; determining a frame of an input audio signal of the multimode audio codec to be an active region of the audio signal; maintaining a current operating mode of the multimode audio codec; and reducing the coding rate of the multimode audio codec to a coding rate lower than the requested coding rate. | 11-19-2015 |

20160064004 | MULTIPLE CHANNEL AUDIO SIGNAL ENCODER MODE DETERMINER - It is inter alia disclosed a method comprising: determining an indication of similarity between a first audio frame of a multiple channel input audio signal and a second audio frame of the multiple channel input audio signal; and determining a coding mode for a multiple channel audio spatial encoder dependent on each of: data indicating a coding mode of a mono audio encoder for the first audio frame of the multiple channel input audio signal; a coding mode of the multichannel spatial audio encoder for the first audio frame of the multiple channel input audio signal; and the indication of similarity. | 03-03-2016 |
20160078877 | AUDIO SIGNAL ENCODER - An apparatus comprising: a channel analyser configured to determine for a first frame of at least one audio signal a set of first frame audio signal multi-channel parameters; a multichannel difference selector configured to select for the first frame groups of elements of the set of first frame audio signal multi-channel parameters based on a value associated with the first frame; and a multichannel parameter encoder configured to generate an encoded first frame audio signal multi-channel parameter based on the selected groups of elements of the set of first frame audio signal multi-channel parameters. | 03-17-2016 |
20160086368 | Image Point of Interest Analyser with Animation Generator - An apparatus comprising a point of interest analyser configured to define at least one region within an image as an interest region, determine a position associated with the at least one region; an audio track generator configured to determine at least one audio signal based on the position; and an animated presentation generator configured to generate an animated image comprising the at least one region and the at least one audio signal. | 03-24-2016 |
20160105602 | METHOD, APPARATUS AND COMPUTER PROGRAM FOR AUTOMATICALLY CAPTURING AN IMAGE - An apparatus comprising: means for processing, at a first time, a user-input to determine a position condition defined in respect of an object that is yet to be included in a sensed image; and means for automatically capturing, after the first time, a sensed image including a first object not included in the sensed image at the first time, in response to determination that the user-input position condition is satisfied in respect of the first object. | 04-14-2016 |
