摘要： A method and a system enabling inter-destination synchronization of processing of content of at least a first and second media stream, wherein said first and second media stream are associated with one or more markers for marking one or more content parts of said first and second media streams respectively. The method comprises the steps of: detecting a first marked content part in said first media stream and a second marked content part in said second media stream, said first and second market content part being associated with a first and second marker respectively; associating first timing information, preferably comprising a first clock time, with said detected first marked content part and associating second timing information, preferably comprising a second clock time, with said detected second marked content part; determining a timing difference on the basis of said first and second timing information; and, generating on the basis of said timing difference synchronization information for enabling a first and/or second synchronization client to adjust the processing of said first and/or second media stream respectively.

摘要： A system is provided for enabling correlating timeline information between a first media stream and a second media stream which are both associated with a common play-out timeline. The system comprises at least two stream monitors arranged for providing identification information for a media stream by obtaining a persistent identification of one or more media samples of the media stream, determining a timestamp value associated with the persistent identification, and providing the timestamp value and the persistent identification as the identification information. Furthermore, a correlation subsystem is provided for combining the identification information to enable correlating timeline information of the first media stream to timeline information of the second media stream by matching a first persistent identification of the first media stream to a second persistent identification of the second media stream and thereby matching a first timestamp value of the first media stream to a second timestamp value of the second media stream. The system enables media synchronization to be provided for a plurality of devices in a segment of a media distribution network with less computational complexity and/or bandwidth.
