    • A change to the high level syntax of the H.264/MPEG-4 AVC based Multiview Coding standard is made to allow for efficient management of the reference pictures lists. The invention allows for inter-view reference pictures to be duplicated in the final reference list by modifying the equation that is used to select the index of the inter-view picture that is to be added to the reference list. Duplication of a reference picture is valuable when a modified version of the reference picture is used as a reference picture along with the original reference picture, such as in weighted prediction and adaptive reference filtering. An efficient implementation of the reordering of reference pictures is also achieved through an implementation of the invention. Reordering of reference pictures can improve coding efficiency by enabling pictures that are more correlated to the current picture to be present in the lower indices of the reference picture list. In the MVC extension, a new set of RPLR commands were introduced to reorder inter-view reference pictures. The equations specified in the derivation of the view index value in the current MVC specification are modified to allow management of the reference pictures lists through another implementation of the invention. This modification removes the restrictions imposed in the current specification and additionally allows duplication of an interview reference picture in the reference list.
    • 对基于H.264 / MPEG-4 AVC的多视图编码标准的高级语法的改变是为了有效地管理参考图片列表。 本发明允许通过修改用于选择要添加到参考列表的视频间图像的索引的等式来将视频间参考图像复制在最终参考列表中。 当参考图像的修改版本与原始参考图像一起用作参考图像时,例如在加权预测和自适应参考滤波中,参考图像的复制是有价值的。 通过实施本发明也可以实现参考图片的重新排序。 参考图片的重新排列可以通过使与当前照片更相关的图片能够出现在参考图片列表的较低索引中来提高编码效率。 在MVC扩展中,引入了一组新的RPLR命令来重新排序视频间参考图片。 在当前MVC规范中导出视图索引值中指定的等式被修改以允许通过本发明的另一实现来管理参考图片列表。 该修改消除了当前规范中施加的限制,并且还允许在参考列表中复制面试参考图片。
