    • A scalable video bitstream may have an H.264/AVC compatible base layer (BL) and a scalable enhancement layer (EL), where scalability refers to color bit depth. The SVC standard allows spatial inter-layer prediction, wherein a residual in the EL is generated which is then intra coded. Another spatial intra-coding mode for EL is pure intra coding (I_NxN). The invention discloses a new intra-coding mode and two new inter coding modes, particularly for bit depth scalability. The new intra coding mode uses encoding of the residual between upsampled reconstructed BL and original EL, using mode selection. Two possible modes are residual prediction from BL and additional intra-coding of this residual. The new inter coding modes use also prediction of EL from reconstructed BL. In a first inter coding mode, the residual is encoded using Motion Estimation based on this residual. In a second inter coding mode, the residual is encoded using upsampled motion information from the BL.
    • 可分级视频比特流可以具有H.264 / AVC兼容的基本层(BL)和可缩放增强层(EL),其中可伸缩性指的是颜色位深度。 SVC标准允许空间层间预测,其中生成EL中的残差然后进行帧内编码。 EL的另一空间帧内编码模式是纯帧内编码(I_NxN)。 本发明公开了一种新的帧内编码模式和两种新的帧间编码模式,特别是用于比特深度可扩展性。 新的帧内编码模式使用模式选择对上采样的重建BL和原始EL之间的残差进行编码。 两种可能的模式是来自BL的剩余预测和该残差的附加帧内编码。 新的帧间编码模式还使用重建BL的EL预测。 在第一帧间编码模式中,使用基于该残差的运动估计对残差进行编码。 在第二帧间编码模式中,使用来自BL的上采样运动信息来编码残差。

    • The invention presents a scalable solution to encode the whole 12-bit raw video once to generate one bitstream that contains an H.264 /AVC compatible base layer and a scalable enhancement layer. If a color bit depth scalable decoder is available at the client end, both the base layer and the enhancement layer sub-bitstreams will be decoded to obtain the 12-bit video and it can be viewed on a high quality display that supports more than eight bit; otherwise only the base layer sub-bitstream is decoded using an H.264 /AVC decoder and the decoded 8-bit video can be viewed on a conventional 8-bit display. The enhancement layer contains a residual based on a prediction from the base layer, which is either based on bit-shift or based on an advanced bit depth prediction is utilized, wherein the advanced bit depth prediction method is a Smoothed Histogram method or a Localized Polynomial Approximation method.
    • 本发明提出了一种可扩展的解决方案,用于对整个12位原始视频进行编码以产生一个包含H.264 / AVC兼容基本层和可伸缩增强层的比特流。 如果在客户端可以使用彩色位深度可伸缩解码器,则基础层和增强层子比特流将被解码以获得12位视频,并且可以在支持多于八个的高质量显示器上观看 位; 否则仅使用H.264 / AVC解码器解码基本层子比特流,并且可以在传统的8位显示器上观看解码的8位视频。 增强层包含基于来自基本层的预测的残差,其基于位移或基于高级位深度预测,其中高级位深度预测方法是平滑直方图或局部多项式 近似法。

    • A scalable video bitstream may have an H.264 /AVC compatible base layer (BL) and a scalable enhancement layer (EL), where scalability refers to color bit depth. The H.264/AVC scalability extension SVC provides also other types of scalability, e.g. spatial scalability where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled in two logical steps (TUp, BDUp), one being texture upsampling and the other being bit depth upsampling. Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values that each pixel can have, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. The BL information is upsampled at the encoder side and in the same manner at the decoder side, wherein the upsampling refers to spatial and bit depth characteristics.
