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

A video decoder () for decoding an encoded video signal comprising encoded picture data to reconstruct a plurality of pictures of a video sequence of a video. 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.

Video coding using a coded picture buffer

To increase efficiency of a bit-depth scalable data-stream an inter-layer prediction is obtained by mapping samples of the representation of the picture or video source data with a first picture sample bit-depth from a first dynamic range corresponding to the first picture sample bit-depth to a second dynamic range greater than the first dynamic range and corresponding to a second picture sample bit-depth being higher than the first picture sample bit-depth by use of one or more global mapping functions being constant within the picture or video source data or varying at a first granularity, and a local mapping function locally modifying the one or more global mapping functions and varying at a second granularity smaller than the first granularity, with forming the quality-scalable data-stream based on the local mapping function such that the local mapping function is derivable from the quality-scalable data-stream.

Bit-depth scalability

The usual coding order according to which the reference view is coded prior to the dependent view, and within each view, a depth map is coded subsequent to the respective picture, may be maintained and does lead to a sacrifice of efficiency in performing inter-view redundancy removal by, for example, predicting motion data of the current picture of the dependent view from motion data of the current picture of the reference view. Rather, a depth map estimate of the current picture of the dependent view is obtained by warping the depth map of the current picture of the reference view into the dependent view, thereby enabling various methods of inter-view redundancy reduction more efficiently by bridging the gap between the views. According to another aspect, the following discovery is exploited: the overhead associated with an enlarged list of motion predictor candidates for a block of a picture of a dependent view is comparatively low compared to a gain in motion vector prediction quality resulting from an adding of a motion vector candidate which is determined from an, in disparity-compensated sense, co-located block of a reference view.

Efficient multi-view coding using depth-map estimate for a dependent view

Concepts for predictive picture coding using template matching are presented which may, for a given computation complexity, result in an increased coding efficiency.
