Said invention can be used, in particular for reducing a data rate during a video data transmission. An analysis of video scene texture by an encoder is performed in such a way that synthesized texture areas are determined. The video scene coding is carried out with the aid of data for said synthesized texture areas. Information on the texture of said areas, metadata used for describing the determined areas and the synthesized texture are generated. Coded data and metadata are evaluated by a decoder in such a way that the video scenes are reconstructed by synthetically generated textures by means of evaluation of metadata for determined areas.

摘要： A further coding efficiency increase is achieved by, in hybrid video coding, additionally predicting the residual signal of a current frame by motion-compensated prediction using a reference residual signal of a previous frame. In other words, in order to further reduce the energy of the final residual signal, i.e. the one finally transmitted, and thus increase the coding efficiency, it is proposed to additionally predict the residual signal by motion-compensated prediction using the reconstructed residual signals of previously coded frames.

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： Rate control mechanisms for video encoding aim to provide the best possible video quality while keeping given conditions on transmission rate and decoding delay. In order to achieve a constant video quality, the anchor and non-anchor frames of different frame types are encoded using a different number of bits. However, since video sequences generally contain widely varying picture content and previously coded frames are used to predict a given frame, a suitable assignment of frame target bit rates is hard to determine, especially for non-anchor frames. According to the invention, non-anchor frames are coded using a fixed quantization parameter. Since the quantization parameter used for the encoding of non-anchor frames is directly derived from the average quantization parameter of the previously encoded anchor frame, such approach ensures a constant video quality. Beside of that, the complexity of the rate control strategy is reduced, because no macroblock-level rate control is applied for the encoding of non-anchor frames.
摘要翻译：视频编码的速率控制机制旨在提供最佳视频质量，同时保持传输速率和解码延迟的条件。为了实现恒定的视频质量，使用不同数量的比特对不同帧类型的锚和非锚定帧进行编码。然而，由于视频序列通常包含广泛变化的图像内容，并且先前编码的帧用于预测给定的帧，因此难以确定帧目标比特率的适当分配，特别是对于非锚帧。根据本发明，使用固定的量化参数对非锚定帧进行编码。由于用于非锚定帧的编码的量化参数直接从先前编码的锚帧的平均量化参数导出，所以这种方法确保了视频质量的恒定。除此之外，由于没有宏块级速率控制被应用于非锚帧的编码，所以速率控制策略的复杂性被降低。

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.
