Pixelmetrix Eyes OTT QoS/QoE

At NAB in Las Vegas, Pixelmetrix will unveil its OTT Media Grinder (OMG), a system for validation of over-the-top (OTT) delivery infrastructure. The OMG is designed to enable operators to qualify and periodically audit OTT service quality by simultaneously emulating thousands of OTT clients, generating large amounts of OTT transaction traffic into the network.The OMG simulates thousands of OTT clients (iPhone, iPad, etc) with multiple user-defined behaviors. "Pools" of clients can behave well (for example, consume content to the end), while other pools of clients can randomly change speeds, drop connections, or "flap" between adaptive bitrates.The system uses Pixelmetrix's VideoMargin Metrics to quantify the QoS/QoE performance factors for OTT delivery by measuring network, HTTP and video layer performance. Packaged in 1RU, dedicated GigE Interfaces are available for management and load generation. The OMG is designed to be operated stand-alone in a single location, or in a distributed, coordinated, multi-site configuration.
