    • 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。

    • Video decoding for any standard mainly includes the steps of entropy decoding (E), inverse transformation/inverse quantization (ITIQ) and motion compensation (MC). These steps can work independently and in parallel after getting the required information. Known video decoders suffer from bottlenecks resulting from centrally organized processing. An apparatus for decoding video data organized in blocks comprises a plurality of processing modules (E, ITIQ, MC) to be passed sequentially by the data, wherein the data output of a first module (101) triggers the start of the further processing of said data in a subsequent second module (301,302), and wherein at least the first and the second module can process simultaneously two or more of said data blocks and include pipeline buffers for storing the two or more data blocks. An advantage of the invention is that the idle time of processing blocks is reduced, which improves decoding efficiency.

    • Video decoding includes very similar processing steps for different standards. The processing can work independently and in parallel in separate modules. Known multi-standard video decoders suffer from bottlenecks resulting from centrally organized processing. An improved apparatus for decoding video data comprises common elements of a RISC processor, including instruction providing unit (51,52,53, 54), queuing unit (55) and ALU (59), and special video processing modules, wherein the video processing modules are embedded in the RISC processor, so that they also receive instructions through the instruction bus (IB) and provide (IRB) data to the queuing unit (55), like the common RISC processor elements. The special video processing modules include a motion compensation unit (510), means (512) for performing IDCT and inverse quantization, an entropy decoding unit (513) and a filter unit (515).
