Title: (EN) CORRELATING TIMELINE INFORMATION BETWEEN MEDIA STREAMS
Abstract:
(EN)

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.
