The invention provides an interrogator for obtaining information associated with a caller identification, such as a telephone number, transmitted within an incoming telephone call including: a receiving device configured to receive the incoming telephone call and to extract the caller identification from the incoming telephone call; an interrogating device configured to receive the extracted caller identification from the receiving device and to interrogate information associated with the caller identification from an external data base, which is configured to operate independently from the user voice communication device for which the incoming telephone call is intended for; and a forwarding device configured to receive and to forward the interrogated information.

Automatic caller identification translation

A concept for transmitting information from a client to a server is described, the client being for streaming visual content from the server and for integrating the visual content into a 3D scene of a user application, and the client being for obtaining a rendered view of the 3D scene.

Client-server communication for streaming of visual content

Block-based coding of a picture is rendered more effective by providing an intra-prediction coding concept according to which a certain block of the picture is intra-prediction coded using a certain intra-coding mode by partitioning the predetermined block into partitions along a certain dimension with the number of partitions being greater than two and/or the partitions being one sample wide along the certain dimension with the partitions being, for reconstruction purposes, sequentially subject to spatial prediction using the intra-prediction coding mode signaled for the certain block followed by correcting the thus obtained predictor using a prediction residual so that for preceding partitions a reconstruction of the samples is available to the decoder at the time of processing the next, then current, partition. Signaling overhead with respect to the partitioning may be left off or may be kept low.

Partition-based intra-coding concept

A video decoder for decoding a video from a data stream is configured to decode an indication from the data stream which is valid for a sequence of pictures of the video, and indicates that RASL pictures within the sequence of pictures are coded in a manner excluding a predetermined set of one or more coding tools.

Video coding concept allowing for limitation of drift

A video decoder is configured to decode a plurality of video frames which are subdivided into a set of one or more slices. The decoder evaluates slice type information indicating whether a slice is encoded using an independent coding mode having no prediction of video content of a current frame on the basis of a video content of a previous frame, or using a single-predictive mode having a prediction of a block of pixels on the basis of one block of pixels of a previous frame, or using a bi-predictive mode having a prediction of a block of pixels on the basis of two or more blocks of pixels of one or more previous frames, to select a mode of operation for decoding a slice.

Video decoder, video encoder, method for decoding a video content, method for encoding a video content, computer program and video bitstream

A video decoder for decoding a video from a data stream using block-based predictive decoding is arranged to derive, using inter prediction, a first prediction, p, for a current block, derive, using intra prediction, a second prediction, p, for the current block determine a scalar weighting parameter, α, based at least in part on a look up table using prediction parameter information of blocks neighboring the current block, determine a prediction signal, q, for the current block as a weighted sum, of the first prediction, p, and the second prediction, p, using, at least in part, the scalar weighting parameter, α, and decode the current block using the prediction signal, q.

Composed prediction and restricted merge

A picture in a data stream is subdivided into different size transform bocks. For a transform block, a transformation is selected by checking whether the block's size exceeds a threshold. If it does, a default technique is used to select the transformation. If it does not, a transformation is used from a list of transformations as identified by an index, the list including an identity transformation and non-identity transformations. A coefficients block in the data stream is decoded, and if the selected transformation is the identity transformation, then the coefficients block is used as a residual sample array, and if the selected transformation is not the identity transformation, the coefficients block is subjected to an inverse transformation corresponding to the selected transformation to obtain a residual sample array used to correct a prediction for the transform block.

Unified transform type signaling and transform type dependent transform coefficient level coding

An encoding scheme for encoding a sequence of integer values comprises encoding a value at a predetermined position and then consecutively calculating and encoding differences between neighboring values. A respective decoding scheme is also provided. These encoding and decoding schemes provide a more efficient encoding concept.

A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

Concept for picture/video data streams allowing efficient reducibility or efficient random access

An apparatus includes an encoder, which receives image or video data, encodes the data and provides a bitstream. The encoder includes a CABAC encoder, which receives a binary valued syntax element associated with a block of the data to be encoded, and encodes, using a selected context model, the syntax element into coded bits for the bitstream. The syntax element includes a tool flag indicating whether or not certain coding tool is employed when encoding a block of the data. For a block of the data which exhibits an aspect ratio larger than 2 and for a block of the data which exhibits an aspect ratio less than or equal to 2, and to which blocks the certain coding tool is applicable, first and second context models for encoding the tool flag are selected from a group of one or more first and second context models, respectively.

Use-case driven context model selection for hybrid video coding tools

An encoding scheme is provided for arithmetically encoding a sequence of information values into an arithmetic coded bitstream by providing the bitstream with entry point information, allowing for resuming arithmetic decoding of the bitstream from a predetermined entry point onward. A respective decoding scheme is also provided. These encoding and decoding schemes provide more efficient encoding in view of the decoding speed.

An apparatus configured to select a predetermined intra prediction mode out of a plurality of intra-prediction modes which includes a first set of intra-prediction modes and a second set of matrix-based intra-prediction modes. The apparatus is configured to select a subset of one or more secondary transforms dependent on the predetermined intra prediction mode so that the subset is nonempty in case of the predetermined intra prediction mode being contained in the first set of intra-prediction modes or in the second set of matrix-based intra-prediction modes. The apparatus is configured to derive a transformed version of a prediction residual for a predetermined block, which is related to a spatial domain version of the prediction residual of the predetermined block via a transform defined by a concatenation of a primary transform and a predetermined secondary transform out of the subset of secondary transforms.

Coding using matrix based intra-prediction and secondary transforms

An encoder for hybrid video coding, the encoder for providing an encoded representation of a video sequence on the basis of an input video content, and the encoder configured to: determine one or more syntax elements related to a portion of the video sequence; select a processing scheme to be applied to the portion of the video sequence based a property described by on the one or more syntax elements, the processing scheme for acquiring a sample for a motion-compensated prediction at an integer and/or fractional location within the portion of the video sequence; encode an index indicating the selected processing scheme such that a given encoded index value represents different processing schemes depending on the property described by the one or more syntax elements; and provide, as the encoded representation of the video sequence, a bit stream including the one or more syntax elements and the encoded index.
