Tektronix Screen for PQM 300 Program QoS Monitor

The PQM300 Program Quality of Service (QoS) Monitor is a multi-channel solution for monitoring the quality of compressed video. From the pioneer in picture quality measurement technology, which brought you the world’s first objective picture quality analysis tool, comes a natural extension of this capability designed for those engaged in the delivery of compressed video.

Bandwidth means money and the PQM300 can help the user better manage it. Using the Picture Defect Index (PDI) scale, the user can objectively allocate bandwidth on an individual program basis, using it where the user need it most without wasting it on a single program. The PQM300 PDI scale is derived from the industry standard Picture Quality Rating (PQR) scale made popular by the Tektronix PQA200 Picture Quality Analysis System. This ensures confidence that the displayed QoS results will approximate the experience of human viewers.

The PQM300 enables the user to quickly identify the most annoying MPEG picture defects before they become customer complaints. This dependable single-ended (no reference) solution provides an instantaneous view of the most annoying MPEG compression-related artifacts, such as blockiness. The PQM300 also aids in detecting uncorrelated Gaussian noise, frozen frames and loss of service. Unlike limited devices that can only scan one program at a time, the PQM300 is designed to simultaneously monitor all of your programs in real time so that no picture defects go undetected.
