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

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
