| 摘要 | Disclosed herein is a method of synchronizing of a plurality of data streams having time-stamped packets, wherein the plurality of data streams are of a first type and at least a second type different than the first type, of which at least one stream of the first type is to be processed at a server. The method includes re-dating a timestamp of a packet, using a processor, based on an estimated relative delay for transport up to the server between first-type and second-type streams and a predicted relative delay representative of a processing time duration between first-type and second-type streams, thereby allowing the relative delays to cancel at least partially. | ||

A method of synchronizing a plurality of data streams having time-stamped packets, wherein the plurality of data streams are of a first type and at least a second type different than the first type, of which at least one stream of the first type is to be processed at a server, the method comprising: re-dating a timestamp of a packet, using a processor, based on an estimated relative delay for transport up to the server between first-type and second-type streams and a predicted relative delay representative of a processing duration difference between first-type and second-type streams, thereby allowing the relative delays to cancel at least partially. | ||
