A more effective coding/decoding of a sequence of information values and, for instance, one which enables implementations of increased processing speed, is achieved by rendering the binarization of the information values dependent on previously coded/decoded information values.

Coding concept for a sequence of information values

Decoder for decoding a picture, wherein blocks into which the picture is subdivided are assigned to a set of prediction types, which include intra prediction and inter prediction. For each of predetermined intra-predicted blocks, the decoder is configured to derive, from the data stream, an information on a partitioning of the respective predetermined intra-predicted block into partitions. The decoder is configured to derive, from the data stream, for each partition of the respective predetermined intra-predicted block, a partition-specific prediction residual signal related to a spatial domain prediction residual signal of the respective partition of the respective predetermined intra-predicted block via a predetermined transform. The predetermined transform can be identified out of a set of transforms including a first transform and a second transform, which equals a concatenation of a primary transform and a secondary transform applied onto a subset of coefficients of the primary transform.

Decoder, encoder and methods comprising a coding for intra subpartitions

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.

File generator, file parser, methods and video bitstream with improved access unit delimiter, end of sequence, end of bitstream and further non-video coding layer network access layer units

Findings are described according to which a higher compression rate or better rate/distortion ratio may be achieved by adopting or predicting second coding parameters used for encoding a second view of the multi-view signal from first coding parameters used in encoding a first view of the multi-view signal. In other words, redundancies between views of a multi-view signal may not be restricted to the views themselves, such as the video information thereof, but that the coding parameters in parallelly encoding these views show similarities which may be exploited in order to further improve the coding rate.

Multi-view signal codec with reusing coding parameters

Various concepts for media content streaming are described. Some allow for streaming spatial scene content in a spatially unequal manner so that the visible quality for the user is increased, or the processing complexity or used bandwidth at the streaming retrieval site is decreased. Others allow for streaming spatial scene content in a manner enlarging the applicability to further application scenarios.

Spatially unequal streaming

A video data stream having a video encoded thereinto and is described. It includes first timing information on first coded picture buffer, CPB, removal times to be applied at decoder side in case of buffering a complete version of the video data stream, and second timing information on second CPB removal times to be applied at decoder side for buffering a reduced version of the video data stream, differing from the video data stream by removal of a portion of the video data stream from the complete version of the video data stream. Corresponding video encoders, video decoders, network nodes, apparatuses for managing the coded picture buffer, CPB, of a video decoder, and apparatuses for splicing together video data streams are also referred to.

Hypothetical reference decoder

A better rate distortion ratio is achieved by making interrelationships between coding parameters of different planes available for exploitation for the aim of redundancy reduction despite the additional overhead resulting from the need to signal the inter-plane prediction information to the decoder. In particular, the decision to use inter plane prediction or not may be performed for a plurality of planes individually. Additionally or alternatively, the decision may be done on a block basis considering one secondary plane.

Inter-plane prediction

Wedgelet separation lines of neighboring blocks are predicted from each other by aligning the wedgelet separation lines of such neighboring blocks to each other, thereby reducing the side information coding rate that may be used.

Effective wedgelet partition coding

Different concepts for improving video coding efficiency are described, many of them allow for video coding in a manner realizing tile-independent coding with reducing, however, the coding efficiency losses otherwise associated with the tile-dependency disruptions, with nevertheless merely marginally, if all, modifying the codec behavior alongside the tile boundaries.

Inter-prediction concept using tile-independency constraints

An apparatus () for receiving an input video data stream according to an embodiment is provided. The input video data stream has a video encoded thereinto. The apparatus () is configured to generate an output video data stream from the input video data stream.

Video encoder, video decoder, methods for encoding and decoding and video data stream for realizing advanced video coding concepts

A method for checking a video data stream having a video encoded thereinto on trustworthiness comprises: subjecting a predetermined portion of the video data stream, or data derived therefrom, to a hash function to obtain a hash value; deriving a digital signature from the video data stream; and checking whether the hash value fits to the digital signature to determine whether the video data stream is trustworthy.

Concept for trustworthiness check of video data streams

Concepts are described, including encoding, processing and decoding of a data stream having a video encoded thereinto, wherein the video comprises a plurality of pictures, wherein the data stream comprises a plurality of pictures in at least two layers, wherein the pictures of at least one layer are split into a predetermined layer-specific number of subpictures, one or more of the pictures or subpictures of one layer corresponds to one picture or subpictures in one or more other layer, and at least one of the subpictures comprises boundaries for boundary extension for motion compensation, and an indication that at least one of the boundaries of corresponding subpictures or corresponding pictures in different layers are aligned with each other.

Video coding in relation to subpictures

The video decoder () comprises an input interface () configured for receiving the encoded video signal comprising the encoded picture data. Moreover, the video decoder () comprises a data decoder () configured for reconstructing the plurality of pictures of the video sequence depending on the encoded picture data. Moreover, further video decoders, video encoders, systems, methods for encoding and decoding, computer programs and encoded video signals according to embodiments are provided.

Encoder and decoder, encoding method and decoding method for reference picture resampling extensions

An apparatus for decoding a picture is configured to partition the picture into coding blocks, using recursive multi-tree splitting. Splitting schemes for the multi-tree splitting are described. According to an embodiment, the decoder decodes a split direction flag from a data stream by context adaptive entropy decoding using a context which depends on whether, and discriminates between, a first number of criteria which would be fulfilled in case of a split direction indicated by the split direction flag being horizontal equals a second number of criteria which would be fulfilled in case of the split direction indicated by the split direction flag being vertical, the first number being greater than the second number, and the first number being smaller than the second number.

Encoding and decoding a picture

Interpolation between explicitly signaled CPB (or HRD) parameters at selected bit rates is used to achieve a good compromise between CPB parameter transmission capacity and CPB parametrization effectiveness and may be, particularly, made in an effective manner.
