Method and System for Synchronizing Media Streams

摘要

A method and system for synchronizing two or more media streams, generated by different sources (210, 220). An identifier generator 200 generates identifiers 600 with unique sequence numbers and a unique media identifier in relation to a second media stream generated by second media server 220. The generated identifiers are supplied to an encoder 230 and an identifier storage 205. In the identifier storage 205 a broadcaster stores an associated URL (first media server address & content) with a particular identifier. The identifiers and the second media stream 620A are encoded by the encoder 230 into a carrier (620M) which is recorded or broadcasted. Play-out of the recorded or broadcasted is accomplished by feeding the encoded carrier to a decoder 300, which decodes the identifiers and the second media stream 620B. The decoded identifier is received by a first device 310 that retrieves 560 the stored associated URL for the particular identifier and subsequently request 570 first media server 210 for the first media stream indicated by the associated URL. The first media stream 610 is provided 580 to the first device 310, which is also provided 552 with the decoded second media stream 620B.
