Abstract: An apparatus is disclosed, configured to receive, from first and second spatial audio capture apparatuses, respective first and second composite audio signals comprising components derived from one or more sound sources in a capture space. The apparatus is further configured to identify a position of a user device corresponding to one of first and second areas respectively associated with the positions of the first and second spatial audio capture apparatuses, and to render audio representing the one or more sound sources to the user device, the rendering being performed differently dependent on, for the spatial audio capture apparatus associated with the identified first or second area, whether or not individual audio signals from each of the one or more sound sources can be successfully separated from its composite signal.

Abstract: A method for packing a frame of immersive or omnidirectional content may include: determining one or more head motion statistics for rendering and packing immersive or omnidirectional content; determining a classification of a head motion based, at least partially, on the one or more determined head motion statistics; determining resolution(s) and/or a packing scheme based on determined viewport change rate, extent, change prediction/frequency, etc., as summarized by FIG. 6. If there is little or no head motion, the majority of a frame may be packed with high quality and resolution content of the viewport. If there is a greater amount of head motion, a smaller portion of the frame may be packed with high quality and resolution content of the viewport, and medium/low resolution content may be included with the frame that is associated with non-viewport content.

Abstract: The embodiments relate to a method and a technical equipment for implementing the method. The method comprises receiving encoded omnidirectional video content for displaying, wherein the encoded omnidirectional video content comprises a viewport region, a margin region outside the viewport region and a background region (801); defining image regions to be included in the margin region, wherein the definition is based on a margin speed threshold (802); determining a head speed and a direction of motion (803); determining when the head speed is greater than or equal to the margin speed threshold, and as a response to the determining, adding negative margins in one or more direction with respect to the viewport (804); downloading the viewport with a first quality; and downloading the negative margins at a quality lower than the first quality (805).

Abstract: Apparatuses, systems, methods, and computer programs enable spatial audio rendering that allows for six degrees of freedom of movement of a listener. The spatial audio comprises higher order ambisonic signals. An apparatus includes circuitry for generating audio signal content sets that provide spatial audio scenes; determining positions in which the spatial audio scenes are audible; and associating a subset of audio signal content sets with the determined positions such that a first subset of audio signal content sets is associated with a first position and a second subset of audio signal content sets is associated with a second position. When audio signal content is provided for rendering, the first subset of audio signal content sets is retrieved if the listener is at the first position and if the listener is at the second position the second subset of audio signal content sets is retrieved.

Abstract: This specification describes an apparatus, method and computer program for communicating with a plurality of remote devices in a conference session, outputting, on a display, a user interface comprising a plurality of display portions respectively associated with the plurality of remote devices, and receiving user selection of one or more of the remote devices. Based on the received user selection, the apparatus may cause display of a display portion associated with the one or more selected remote devices on a linked user device which is linked to the apparatus, and enable one or more communications actions for use with the one or more selected remote devices.
