Abstract
A system and method are provided for determining delay of a plurality of media streams. The system and method involve generating, at a source processor, a series of source time packets; transmitting, at the source processor, through a network, the series of source time packets as a source packet stream; generating, at a destination processor, a series of destination time packets; receiving, at the destination processor, through the network, the source packet stream; determining, at the destination processor, a transmission time for the source packet stream based on the source time data and the destination time data; and determining, at the destination processor, a relative synchronization error based on the source signature data and the destination signature data. Each source time packet includes source time data and source signature data. Each destination time packet includes destination time data and destination signature data.
