SYNCHRONIZED DATA PROCESSING BETWEEN RECEIVERS

摘要

A method, a client device and a synchronization server are described for enabling synchronization of data processing by a first and second receiver wherein the method may comprise: said first receiver processing data units of a first broadcast stream, a play-out delay Δtp defining a time interval between transmission of a data unit to said first receiver and the processing of said data unit by said first receiver; initiating transmission of data units of a second broadcast stream to said second receiver, a common timeline correlating one or more data unit in said first stream with one or more corresponding data unit in said second stream; and, selecting one or more data units from a plurality of stored data units corresponding to said second stream, wherein at least part of said selected data units have corresponding data units of said first stream that have been transmitted to said first receiver but that have not been processed by said first receiver due to said play-out delay.

1. Method for enabling synchronization of data processing by a first and second receiver comprising:
said first receiver processing data units of a first broadcast stream, a play-out delay Δtp defining a time interval between transmission of a data unit of said first broadcast stream to said first receiver and the processing of said data unit by said first receiver; initiating transmission of data units of a second broadcast stream to said second receiver, a common timeline correlating one or more data units of said first broadcast stream with one or more corresponding data units of said second broadcast stream; and, selecting for transmission to said second receiver separate from said second broadcast stream, one or more data units from a plurality of stored data units corresponding to data units of said second broadcast stream, wherein at least part of said one or more selected data units have corresponding data units of said first broadcast stream that have been transmitted to said first receiver but that have not yet been processed by said first receiver due to said play-out delay.
