  • Publication number: 20170150140
    Abstract: A measurement system is provided for measuring a change, of a device under test, between a first video sequence having a first video quality and a second video sequence having a second video quality. The measurement system comprises a video signal source configured to provide the first video sequence and the second video sequence, wherein the first video sequence is identified by a first identification indicator and the second video sequence is identified by a second identification indicator. The measurement system further comprises a detecting device configured to detect a change from the first video sequence to the second video sequence based on a difference between the first identification indicator and the second identification indicator.
