    • A system and method for implementing improved decoded picture buffer (DPB) management for scalable video coding and multiview video coding. To address the issue of mismatches in reference picture markings, all prior unnecessary reference pictures can be marked as unused after the decoding of an open decoding refresh (ODR), open layer refresh (OLR), or open view refresh (OVR) picture or, when scalable video coding (SVC) is at issue, an indication can be made in the stream that previous and current reference picture markings are identical. To address the occurrence of potential overflows in the decoded picture buffer, ODR, OLR, or OVR pictures may not be encoded if a switch can cause an overflow m the decoded picture buffer; all prior pictures may be removed from the decoded picture buffer; or prior pictures may removed from the DPB based on certain control indications. Solutions are also provided to address the issue of mismatches in bi-dependent leading pictures.
    • 一种用于实现用于可缩放视频编码和多视图视频编码的改进的解码图像缓冲器(DPB)管理的系统和方法。 为了解决参考图像标记中的不匹配问题,在解码开放解码刷新(ODR),开放层刷新(OLR)或打开视图刷新(OVR)图像之后,可以将所有先前不必要的参考图片标记为未使用, 当可伸缩视频编码(SVC)出现问题时,可以在流中进行指示,即先前和当前的参考图片标记是相同的。 为了解决解码图像缓冲器中潜在的溢出的发生,如果开关可能导致解码的图像缓冲器溢出,则ODR,OLR或OVR图像可能不被编码; 可以从解码图像缓冲器中去除所有先前的图像; 或者可以基于某些控制指示从DPB去除现有图像。 还提供了解决方案来解决双重依赖的主要图片中的不匹配问题。

    • A method and device for encoding, decoding, storage and transmission of a scalable data stream to include layers having different coding properties. The method includes: producing one or more layers of the scalable data stream, wherein the layers are characterized by a coding property, and signaling the layers with the coding property such that they are readable by a decoder to determine the coding property without analyzing the scalable data stream. Also, a method of encoding, decoding, storage, and transmission of a scalable bit stream, wherein at least two scalability layers are present and each layer is characterized by a set of at least one property, such as profile, level and a set of at least one HRD/VBV parameter, that may be different from that of the entire stream, and wherein said a set of at least one property is signaled for at least one layer that is different from the entire stream, wherein signaling of said a set of at least one property may be in said scalable bit stream, in a file format container containing said scalable bit stream, or in a transmission or control protocol for transmission or control of at least one layer of said scalable bit stream.
