    • The present principles relate to a hypothetical reference decoder (HRD) for a Scalable Video Coding extension for a compression algorithm. One such implementation proposes to modify the H.264/AVC HRD for use with the SVC of AVC. That implementation defines HRD constraints for each interoperability point of SVC. One implementation in particular is described, but other implementations are possible and are contemplated by the present principles. The changes for spatial, temporal, and SNR scalability are shown. There are also changes to the related HRD parameters followed that are shown. The several mentioned implementations provide rules for an HRD for SVC. At least one implementation proposes the SVC-HRD rules as modifications to the AVC-HRD rules. A user may use the proposed SVC-HRD rules to build an SVC-HRD and test a bitstream for SVC compliance.
    • 本原理涉及用于压缩算法的可伸缩视频编码扩展的假设参考解码器(HRD)。 一种这样的实现方案提出修改用于AVC的SVC的H.264 / AVC HRD。 该实现为SVC的每个互操作性点定义了HRD约束。 具体描述了一个实施方式,但是其他实施方式是可能的并且由本原理构思。 显示了空间,时间和SNR可伸缩性的变化。 显示随后的相关HRD参数的变化。 这几个提到的实现为SVC的HRD提供了规则。 至少有一个实施方案提出将SVC-HRD规则作为对AVC-HRD规则的修改。 用户可以使用提出的SVC-HRD规则来构建SVC-HRD并测试比特流以符合SVC。

    • Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular implementation accesses a video picture that includes multiple pictures combined into a single picture, and accesses additional information indicating how the multiple pictures in the accessed video picture are combined. The accessed information includes spatial interleaving information and sampling information. Another implementation encodes a video picture that includes multiple pictures combined into a single picture, and generates information indicating how the multiple pictures in the accessed video picture are combined. The generated information includes spatial interleaving information and sampling information. A bitstream is formed that includes the encoded video picture and the generated information. Another implementation provides a data structure for transmitting the generated information.
