Patent number: 11856386Abstract: An apparatus for processing audiovisual data for a scene comprises a receiver (201) for receiving audiovisual data for the scene. The audiovisual data comprises audio data for the scene comprising a plurality of audio elements and image data for at least a first image of the scene where the first image has a first aspect ratio. An image remapper (203) performs a content dependent non-uniform mapping of the first image to a second image which has a different aspect ratio. The image remapper (207) is arranged to generate mapping data describing the content dependent non-uniform mapping. An audio remapper (207) replaces a first audio element of the plurality of audio elements by a second audio element generated by modifying a spatial property for the first audio element in response to the mapping data. The spatial property being modified may be a position and/or spatial spread of the first audio element.Type: GrantFiled: September 10, 2019Date of Patent: December 26, 2023Assignee: Koninklijke Philips N.V.Inventors: Werner Paulus Josephus De Bruijn, Jeroen Gerardus Henricus Koppens

Patent number: 10575112Abstract: An audio signal processing apparatus includes a receiver which receives an audio signal including audio data for at least a first audio object associated with a three dimensional image. The audio signal also includes depth position data indicative of a target depth position for the first audio object. A determiner determines a visual rendering depth range for a target three dimensional display for presenting the three dimensional image, and a mapper for mapping the target depth position to a rendering depth position for the audio object where the mapping is dependent on the visual rendering depth range. The visual rendering depth range may specifically be a depth range in which the three dimensional display can accurately render objects, and the mapper may amend the positions of audio object sound sources such that these match the depth positions of corresponding visual objects presented by the three dimensional display.Type: GrantFiled: August 30, 2016Date of Patent: February 25, 2020Assignee: Koninklijke Philips N.V.Inventor: Werner Paulus Josephus De Bruijn

Patent number: 10440496Abstract: A spatial audio processing apparatus comprises a receiver (101) for receiving audio scene data describing an audio scene comprising spatial audio components and associated position data. The audio components may be provided as audio objects. A distance unit (105) provides a position indication which includes a focus distance that is indicative of a distance from a reference position in the audio scene. An adapter (103) adapts a perceptual emphasis property, such as an audio level, frequency distribution, or degree of diffuseness, of a spatial audio component relative to at least one other spatial audio component of the audio scene in response to a difference measure reflecting a difference between the focus distance and a distance in the audio scene from the reference position to a position of the spatial audio component. An audio renderer (107) renders the resulting audio scene using the received position data. The approach may emphasize audio at the focus distance in the audio scene.Type: GrantFiled: April 6, 2017Date of Patent: October 8, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Werner Paulus Josephus De Bruijn, Leon Maria Van De Kerkhof

The estimator may perform the steps of first finding a matching peak profile for the set of peaks from the set of peak profiles; extracting first room dimension data associated with the matching peak profile(s) from the store; and determining the room dimension estimate in response to the first room dimension data. The peak profiles may represent calculated Eigenfrequencies.Type: GrantFiled: April 24, 2014Date of Patent: March 6, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Werner Paulus Josephus De Bruijn
