摘要： A more efficient way of addressing different bit-depths, or different bit-depths and chroma sampling format requirements is achieved by using a low bit-depth and/or low-chroma resolution representation for providing a respective base layer data stream representing this low bit-depth and/or low-chroma resolution representation as well as for providing a higher bit-depth and/or higher chroma resolution representation so that a respective prediction residual may be encoded in order to obtain a higher bit-depth and/or higher chroma resolution representation. By this measure, an encoder is enabled to store a base-quality representation of a picture or a video sequence, which can be decoded by any legacy decoder or video decoder, together with an enhancement signal for higher bit-depth and/or reduced chroma sub-sampling, which may be ignored by legacy decoders or video decoders.

摘要： A video frame arithmetical context adaptive encoding and decoding scheme is presented which is based on the finding, that, for sake of a better definition of neighborhood between blocks of picture samples, i.e. the neighboring block which the syntax element to be coded or decoded relates to and the current block based on the attribute of which the assignment of a context model is conducted, and when the neighboring block lies beyond the borders or circumference of the current macroblock containing the current block, it is important to make the determination of the macroblock containing the neighboring block dependent upon as to whether the current macroblock pair region containing the current block is of a first or a second distribution type, i.e., frame or field coded.

摘要： An entropy encoding/decoding scheme uses an arithmetic encoder/decoder together with a context modeler for performing a context-based adaptive binary arithmetic coding, which is especially suited for video compression applications. The context modeler includes an initializer for initializing the context modeler by determining and providing initialization probability information to the arithmetic encoder, the initialization probability information to be used by the arithmetic encoder for processing a start symbol of a symbol sequence. The initializer is operative to determine the initialization probability information based on an estimation of the symbol statistics relating to the start symbol such that an initialization probability distribution is different from an equi-probable distribution for all symbols of the symbol set. By means of the initialization, the context-based adaptive binary arithmetic coding/decoding scheme is optimally adjusted before processing a start symbol of the symbol sequence so that no bit rate compression losses because of a delayed context-based adaptation are introduced.

摘要： Binarization a data value comprises binarizing the minimum of the data value and a predetermined cut-off value in accordance with a first binarization scheme, in order to yield a primary prefix. If the data value is greater than the cut-off value, binarizing a difference of the data value minus the predetermined cut-off value in accordance with a second binarization scheme to obtain a binary suffix, the first binarization scheme being different from the second binarization scheme, and appending the primary suffix to the primary prefix is performed. A very effective compression of data values may be achiever by using the binarization scheme for preparing the syntax elements for the arithmetic coding, the binarization scheme substantially being a combination of two different binarization schemes, and by using binary arithmetic coding instead of m-ary arithmetic coding for coding the binarized syntax elements.

摘要： In the scalable video coding in connection with motion compensation both in a base layer and in an enhancement layer, a prediction of the motion data of the enhancement layer is performed by using the motion data of the base layer to obtain a scalability concept, which provides, on the one hand, a maximum flexibility for the calculation of the motion data of the different layers and, on the other hand, allows a lower bit rate.

摘要： A method for encoding a video frame or picture comprises dividing up the video frame or the picture in portions of a first type associated with a first scanning pattern, and portions of a second type associated with a second scanning pattern. Data corresponding to a predetermined of the portions of the video frame or picture is transformed into a two-dimensional transform coefficient array. Fhe transform coefficients are precoded in order to obtain transform data units. One of a first and a second set of context models is chosen depending on as to whether the predetermined portion is a portion of a type being associated with the first or the second scanning pattern. One context model of the chosen one of the first and the second set of context models is assigned to the transform data unit based on the scanning position assigned to the predetermined transform coefficient. Finally, the transform data unit or a sub-unit thereof is arithmetically encoded into a coded bit stream based on the probability estimation with which the assigned context model is associated.
