Abstract: A method, apparatus and computer program product is provided to encode or decode a picture. The method, apparatus and computer program product receives a picture; then encode the picture as one or more slices. The method, apparatus and computer program product encode, into a slice header of a slice of the one or more slices, one or more tile identifiers indicative of one or more tile positions for one or more tiles in the slice. The method, apparatus and computer program product encode one or more assignments of one or more tile identifier values for the one or more tile identifiers indicative of tile positions in a parameter set file. Another or the same method, apparatus and computer program product may be provided to encode or decode an indication of an in-picture-prediction-enabled tile set comprising the one or more dependent tiles by identifying one or more dependent tiles from the one or more tiles. The one or more dependent tiles are dependent on another dependent tile within a coded picture or form a logical atomic unit with another dependent tile.

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 are provided to signal grouping types in an image container file. Relative to the construction of an image container file, the method, apparatus and computer program product construct an image container file having a group box with a grouping type associated with burst-captured images, time-synchronized images captured by a plurality of image capture devices or an image item associated with an audio track. With respect to the processing of an image container file, the method, apparatus and computer program product permit an image container file having a group box with a grouping type associated with one of burst-captured images, time-synchronized images captured by a plurality of image capture devices or an image item associated with an audio track to be processed to cause one or more image items from the image container file to be rendered in accordance with the grouping type.

Abstract: There is disclosed a method, an apparatus and a computer program product for video encoding and decoding. In accordance with an embodiment the method for encoding comprises concluding that a coded video sequence starts at particular position in a bitstream, wherein the coded video sequence is a sequence of coded pictures in decoding order that is independently decodable and is followed by another coded video sequence or the end of the bitstream, and wherein the bitstream comprises access units, and an access unit comprises coded video data for a single time instance and associated other data, and an access unit comprises one or more network abstraction layer (NAL) units; and indicating in an access unit delimiter to treat the NAL unit(s) associated with the access unit delimiter as a start of a coded video sequence.

Abstract: There is disclosed a method, an apparatus and a computer program product for video encoding and decoding. In accordance with an embodiment the method comprises obtaining an intra random access point picture from a first location of a coded video bitstream and determining whether the intra random access point picture is reusable in at least a second location of the coded video bitstream, the at least second location differing from the first location. If the determining indicates that the intra random access point picture is reusable, providing an identification assigned with the intra random access point picture that the intra random access point picture is a reusable intra random access point picture.

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: A method comprising: encoding an input picture into a coded constituent picture;
reconstructing, as a part of said encoding, a decoded constituent picture corresponding to the coded constituent picture; encoding a spatial region into a coded tile, the encoding comprising: determining a horizontal offset and a vertical offset indicative of a region-wise anchor position of the spatial region within the decoded constituent picture; encoding the horizontal offset and the vertical offset; determining that a prediction unit at position of a first horizontal coordinate and a first vertical coordinate of the coded tile is predicted relative to the region-wise anchor position, wherein the first horizontal coordinate and the first vertical coordinate are horizontal and vertical coordinates, respectively, within the spatial region; indicating that the prediction unit is predicted relative to a prediction-unit anchor position that is relative to the horizontal and vertical offset; deriving a prediction-unit anchor position equal to sum of the first horizontal coordinate and the horizontal offset, and the first vertical coordinate and the vertical offset, respectively; and determining a motion vector for the prediction unit; and applying the motion vector relative to the prediction-unit anchor position to obtain a prediction block.
