Title: (ZH) 在媒体流之间使时间线信息相互关联的系统和方法
Abstract: front page image
(ZH) 提供了一种用于使得能够在第一媒体流和第二媒体流之间使时间线信息相互关联的系统,所述第一媒体流和第二媒体流二者都与公共播出时间线相关联。该系统包括至少两个流监视器,所述流监视器被布置用于通过下述提供针对媒体流的标识信息:获得媒体流的一个或多个媒体样本的持久标识,确定与持久标识相关联的时间戳值,以及提供时间戳值和持久标识作为标识信息。此外,相互关联子系统被提供用于组合标识信息,以使得能够将第一媒体流的时间线信息与第二媒体流的时间线信息相互关联,这通过使第一媒体流的第一持久标识与第二媒体流的第二持久标识匹配,并且从而使第一媒体流的第一时间戳值与第二媒体流的第二时间戳值匹配。可系统化的媒体同步在较小计算复杂度和/或带宽的情况下被提供用于媒体分发网络的分段中的多个设备。
