Modified Stream Synchronization
First Claim
1. Method for inter-destination synchronization of at least a first and at least a second stream, said second stream being associated with an output stream of a media stream modification unit using said first stream as an input stream, the method comprising:
- providing first arrival time information of a packet in the first stream arriving at a first synchronization point and second arrival time information of a packet in the second stream arriving at a second synchronization point;
providing synchronization correlation information on a synchronicity relationship between said input stream and said output stream; and
calculating delay information based at least on the first and second arrival time information and the synchronization correlation information.

Abstract
A method and system for inter-destination synchronization of at least a first and a second stream is described, wherein the second stream is the output stream of a media stream modification unit using the first stream as an input stream. The method comprises the steps of: providing first arrival time information of a packet in the first stream arriving at a first synchronization point and second arrival time information of a packet in the second stream arriving at a second synchronization point; providing synchronization correlation information on the synchronicity relationship between said input stream and said output stream; and, calculating delay information on the basis of the first and second arrival time information and the synchronization correlation information.

13. A synchronization unit for synchronizing the output of at least a first synchronization point receiving a first media stream and a second synchronization point receiving a second media stream, said second stream being the output stream of a media stream modification unit using the first stream as an input stream, the synchronization unit comprising:
-
a first input for receiving first timing information associated with a packet in a stream, said stream being associated with a first synchronization point and second arrival time information of a packet in the second stream arriving at a second synchronization point; a second input for receiving synchronization correlation information on a synchronicity relationship between said input stream and said output stream; and a processor for calculating delay information based at least on the first and second arrival time information and the synchronization correlation information. - View Dependent Claims (14, 15)
