摘要:
Methods and systems for inter-destination synchronization in first and second receivers for content parts associated with a play-out timeline are disclosed. First timing information comprising first content part identifiers and associated first clock times may be determined, where the first receiver may receive a first content part identifier comprising first fingerprints for identifying a first content part in a first media stream. Second timing information comprising second content part identifiers and associated second clock times may be determined, where the second receiver may receive a second content part identifier identifying a second content part in a second media stream based on the first and second timing information. A timing difference in processing a content part in the first and second media streams may be calculated. Based on the timing difference, synchronization information for inter destination synchronization between said first and second streams may be generated.
