VQM is a standardized method of objectively measuring video quality that closely predicts the subjective quality ratings that would be obtained from a panel of human viewers. The technology is covered by four U.S. patents owned by NTIA/ITS. End-users and service providers can utilize VQM tools to specify/verify system performance, compare competing service offerings, maintain and monitor the quality of their networks, and optimize the use of limited network resources such as bit-rate. Due to its excellent performance in the International Video Quality Expert’s Group (VQEG) Phase II validation tests, the NTIA/ITS VQM methods were adopted by the ANSI as a U.S. national standard (ANSI T1.801.03-2003), and as international ITU Recommendations (ITU-T J.144, and ITU-R BT.1683, both adopted in 2004).

NTIA/ITS would like as many people as possible to benefit from this technology, so we have made VQM software downloads available that may be freely used for both non-commercial and commercial purposes. VQM tools are available for both the Windows and Linux operating systems and customized for different applications (e.g., batch processing, command line processing, and end-to-end in-service monitoring).
