Abstract:
Since its finalization in 2001 Recommendation ITU-R BS.1534, nicknamed MUSHRA, has become very popular. MUSHRA is an acronym for “multi stimulus with hidden reference and anchors.” Many researchers created variants of the original design and called it still MUSHRA, and very often test reports are missing important information about test parameters and statistical analysis. Very often the mandatory anchor is not used.
ITU-R WP 6C is currently working on a revision of MUSHRA. This revision will specify in more detail how to perform the test and the statistical analysis, will add some of the most popular variants as official alternatives, and will offer new, more powerful anchors.
This workshop will present current discussions and results from the spring 2012 meeting of ITU-R.
