Abstract: The embodiments relate to a method at a sender device, the method including receiving, as a response to a delivered indication of a number of supported subpictures, from a receiver an indication on a number of subpictures allowed in an encoded image data; partitioning a bitstream representing an image data into subpictures, the amount of which corresponds to the indicated number of subpictures; generating an encoded bitstream including said subpictures; delivering the encoded bitstream to a receiver apparatus; and delivering required parameter sets for said subpictures to said receiver apparatus. The embodiments also concern a method at a receiver device, and corresponding devices.

Abstract: A method, apparatus and computer program product create a media presentation description with a first representation set and a second representation set. The first representation set belongs to a first adaptation set and the second representation set belongs to a second adaptation set and the first representation set is associated with the first media entity and the second representation set is associated with the second media entity. The method, apparatus and computer program product encode, in the media presentation description, an adaptation and representation grouping descriptor. The adaptation and representation grouping descriptor groups the first representation set with the second representation set based on the grouping type.

Abstract: An apparatus, method and computer program is disclosed. The apparatus may comprise means for providing first virtual content for presentation, which first virtual content is associated with a first space and comprises one or more first virtual objects. One of the first virtual objects may comprise one or more virtual objects having respective audio signals and another may represent a miniature representation of a second space into which the user can transition. The miniature representation may have a second scale, smaller or larger than the first scale, and may comprise one or more second virtual objects having respective audio signals audible from outside of the second space. The apparatus may further comprise means for determining whether at least part of the user is within the first space or the second space, and dependent on the determination, modifying the audio signal of one or more of the first or second virtual objects.
