摘要: A method for measuring quality of packetized audio and video transmission over a chain includes: providing one or more measurement detectors along the chain; detecting, by detectors, loss bit stream packets at points; determining unique identifier each detected lost packet; sending, list packet identifiers to central monitoring system; constructing, system, simulated point based on stored error-free received identifiers; evaluating deriving score point.
