摘要： A Wyner-Ziv coding scheme jointly utilizes multiple side information at the decoder is described. A new probability model is introduced based on an extended turbo decoding trellis, so that the transitional probability is calculated from the probabilities conditioned on multiple side information. The proposed scheme handles multiple side information in a multi-dimensional manner to potentially achieve coding performance better than either selecting one side information or generating a single side information by averaging several side information. When the decoder receives multiple streams of parity bits, the conditional probabilities on the parity bits from the multiple streams all contribute in turbo decoding. The errors existing in some of the streams can be automatically eliminated during the decoding process.

摘要： Request bits estimation for a Wyner-Ziv codec is described. In one aspect, and prior to communicating Wyner-Ziv parity bits to a Wyner-Ziv decoder, an estimated total number of parity bits to send to the Wyner-Ziv decoder are determined. This estimated number of parity bits allows the Wyner-Ziv decoder to reconstruct a frame of different coded content using the Wyner-Ziv parity bits such that the reconstructed frame will meet particular quality criteria. This estimated number of parity bits is determined independent of a request-bits feedback loop between the Wyner-Ziv coder and the Wyner-Ziv decoder. The estimated number of parity bits is communicated to the Wyner-Ziv decoder for reconstruction and presentation of the frame to a user.

摘要： Method and apparatus for intra prediction mode coding and decoding are disclosed. In one embodiment, the encoding and decoding process assigns individual indices and codewords to DC mode and Planar mode respectively. The flag is set if the current intra prediction mode is equal to any of one or more neighboring intra prediction modes. Variable length codes are designed for a remaining mode set. If the flag is not set, the currently intra prediction mode is encoded using the variable length codes. In another embodiment, multiple most probable modes are used. If the current intra prediction mode is not equal to any of the multiple most probable modes, the current intra prediction mode is encoded using variable length codes designed for the corresponding remaining modes according the ranking order of the remaining modes.

摘要： A method and apparatus for improved intra chroma prediction mode coding are disclosed. Intra prediction exploits the spatial correlation within a picture or within a picture region. In practice, a picture is divided into blocks and the intra mode prediction is performed on a block basis. In newer coding systems, multiple intra coding modes such as Vertical mode, Horizontal mode, DC mode and Diagonal mode, have been used to improve the coding efficiency of intra coding. Furthermore, a Luma_mode has also been used in intra prediction of chroma component to further improve the performance in the High Efficiency Video Coding (HEVC) standard being developed. However, the mode selection information for intra prediction has to be conveyed to the decoder for proper operation. Spatial features in a picture often exist in both luma and chroma components. The intra luma prediction mode and intra chroma prediction mode will have high probability to be the same. Accordingly, an embodiment according to the present invention adaptively assigns variable length codes to a set of mode symbols associated with intra chroma prediction by assigning a shortest code to the Luma_mode. Luma_mode not only can be the best luma mode of the corresponding luma block but also can be selected from several corresponding luma modes. The maximum length of chroma prediction codes is decreased by one bit when Luma_mode is equal to one of frequent modes. The coding efficiency of arithmetic coding of chroma prediction codes is further improved by selecting the context upon neighboring blocks.

摘要翻译： 公开了一种用于改进的帧内色度预测模式编码的方法和装置。 帧内预测利用图片内或图片区域内的空间相关性。 实际上，将图像划分成块，并且以块为基础执行帧内模式预测。 在较新的编码系统中，已经使用诸如垂直模式，水平模式，直流模式和对角线模式的多个帧内编码模式来提高帧内编码的编码效率。 此外，Luma_mode也被用于色度分量的帧内预测，​​以进一步提高正在开发的高效率视频编码（HEVC）标准中的性能。 然而，用于帧内预测的模式选择信息必须被传送到解码器以进行正确的操作。 图片中的空间特征通常存在于亮度和色度分量中。 内部亮度预测模式和内部色度预测模式将具有相同的概率。 因此，根据本发明的实施例通过向Luma_mode分配最短代码来自适应地将可变长度代码分配给与帧内色度预测相关联的一组模式符号。 Luma_mode不仅可以是对应亮度块的最佳亮度模式，还可以从几个相应的亮度模式中选择。 当Luma_mode等于频繁模式之一时，色度预测码的最大长度减少一位。 通过选择相邻块的上下文，进一步提高色度预测码的算术编码的编码效率。
