Pixelmetrix Adds OTT Analytics

Pixelmetrix has announced an update to its OTT Media Grinder (OMG), a system for validation of over-the-top delivery infrastructure. Forming part of the overall service analytics engine of the OMG, the new feature, dubbed VideoMargin Metrics, is intended to find the key contributing factors leading to OTT service quality issues.VideoMargin Metrics is designed to quantify the QoS/QoE performance factors for OTT delivery by measuring network, HTTP and video layer performance. Seven parameters measure each aspect of the delivery domain spanning content server, network, authentication, individual client behavior and collective client behavior. Consolidated service availability is provided as a single number in a "five nines" type of representation.The OMG itself is designed to simulate thousands of OTT clients (iPhone, iPad, etc.) with multiple user-defined behaviors. For example, some pools of clients can consume content to the end, while other pools of clients can randomly change speeds, drop connections, or "flap" between adaptive bitrates.
