  • Patent number: 11991355
    Abstract: Concepts are described, including encoding of a video into data stream and decoding of a data stream having a video encoded thereinto, using motion compensation prediction between pictures of equal resolution and pictures of different resolution, based on motion vectors at a half-sample resolution and on motion vectors at a different resolution using interpolation filters to obtain sub-sample values within a reference sample array. The interpolation filter is selected from two interpolation filter versions different in a higher edge preserving property, and the selection is depending on whether a current picture is equal in picture resolution to the reference sample array in horizontal and/or vertical dimension, and/or a constraint information in the data stream.

  • Publication number: 20240129499
    Abstract: An interleaved multi-layered video data stream with interleaved decoding units of different layers is provided with further timing control information in addition to the timing control information reflecting the interleaved decoding unit arrangement. The additional timing control information pertains to either a fallback position according to which all decoding units of an access unit are treated at the decoded buffer access unit-wise, or a fallback position according to which an intermediate procedure is used: the interleaving of the DUs of different layers is reversed according to the additionally sent timing control information, thereby enabling a DU-wise treatment at the decoder's buffer, however, with no interleaving of decoding units relating to different layers. Both fallback positions may be present concurrently. Various advantageous embodiments and alternatives are the subject of the various claims attached herewith.

  • Publication number: 20240114157
    Abstract: The signalization of the inter-layer dependencies between layers of a multi-layered data stream is described. A good compromise between a too intensive restriction of the potential diversity of inter-layer dependencies on the one hand and a too complex signaling of the inter-layer dependencies on the other hand has been found by describing the inter-layer dependencies by way of a first inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by a base layer-ID and a second inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by an extension layer-ID, the base layer ID and extension layer ID indexing the layers the portions of the multi-layer data stream are associated with.

  • Publication number: 20240064352
    Abstract: A file parser for generating an output video bitstream from a file according to an embodiment is provided. The file parser is configured to receive the file being an input video bitstream, wherein the input video bitstream has a video encoded therein. The input video bitstream has a sample group, the sample group having a network abstraction layer unit; and/or the input video bitstream has an indication that an access unit of a plurality of access units of the input video bitstream or a sample of a plurality of samples of the input video bitstream, which does not have the network abstraction layer unit, should have the network abstraction layer unit. The file parser is configured to generate the output video bitstream from the input video bitstream depending on the sample group.

  • Publication number: 20240056573
    Abstract: Sub-picture extraction is rendered less complex by providing each slice with start position information which indicates a starting position from which onwards the picture is, along a coding path, encoded into the respective slice, relative to an onset position at which the coding path starts traversing a segment the starting position is located in. Alternatively or additionally, sub-picture extraction processes are treated like choosing one layer out of a multi-layer datastream.
