A Graded Entropy Test Sequence Series for Subjective Video Quality Assessment

Andrew McMahon

As part of a desire to standardise subjective testing of video systems, the ITU-R (formerly known as the CCIR) has produced a set of testing methodologies (Recommendation 500), and a library of test sequences (detailed in Recommendation 803). One of the test sequences (“Diva with Noise”) has, over the years, been the centre of argument as to whether it is “critical, but not unduly so”, as called for by Recommendation 500. The main objection to the use of the “Diva” sequence is that it is more critical than material which would actually be broadcast. To date, most codecs fail tests using the existing “Diva with Noise” sequence.
