Abstract: A method, apparatus and computer program product describing groups of overlays, such as semantically correlated overlays, to background media content. In the context of a method, a group of overlays to background media content is defined by metadata (60). The overlays include semantically correlated overlays having alternative overlays representing content with different levels of detail or overlays providing different choices of content. The method also includes receiving client selection of a respective overlay from a group of overlays (62). In response to the client selection, the method causes the respective overlay to be provided. The respective overlay is received (64) for presentation concurrent with background media content (68).

Abstract: A method, apparatus and computer program product creates a viewpoint position structure for media content. The viewpoint position structure specifies a position of a viewpoint defined in a reference coordinate system and an offset of the reference coordinate system with respect to a geographical reference. The method, apparatus and computer program product cause storage of the viewpoint position structure. An indication may be created as to whether the media content is augmented reality media content. The augmented reality media content may comprise a background that is at least partially transparent. The offset may be determined, within the reference coordinate system, relative to a geomagnetic reference direction, based upon one or more of a viewpoint yaw angle, a viewpoint pitch angle, or a viewpoint roll angle.

Abstract: A method, apparatus and computer program product encode, into a container file comprising one or more samples, track fragment run metadata associated with a track fragment run. The track fragment run metadata includes a per-sample part comprising per-sample metadata for one or more samples in the container file and a cyclic part. The track fragment run metadata includes an indication of a pattern appearing earlier in the track fragment run and resolving the cyclic part causes at least a subset of the per-sample part to be set by cyclic assignment of the pattern indication of a pattern appearing earlier in the track fragment run.

Abstract: A method, apparatus and computer program product encode, into a media description, a first information item indicative of a first locator for segment metadata for a set of representations. The method, apparatus and computer program product encode, into the media description, one or more representation-specific information items indicative of representation-specific locator for segment media data for one or more representations of the set of representations. The method, apparatus and computer program product cause storage of the media description with the set of representations.

Abstract: A method, apparatus and computer program product provide a signaling mechanism that could be utilized in conjunction with a media interface and exchange mechanism in a media processing pipeline defined in Moving Picture Experts Group-I (MPEG-I) Network-based media processing (NBMP). In particular, a method, apparatus and computer program product provide a NBMP media interface mechanism that enables virtual reality (VR) stitching within an NBMP-enabled system independent of stitching algorithm used.
