Quality assurance for IPTV

摘要

A tool designed to perform quality assurance on IPTV encoded assets is presented. The tool works on stored MPEG-2 transport stream files and combines a powerful graphical-user-interface with automatic no-reference detectors to handle video quality, audio and field-ordering issues. The tool provides automatic quality assurance of assets before they are made available for streaming and replaces the need for exhaustive viewing tests by human operators.
