Calibration patterns for all major display controlsEvaluation patterns for measuring display and player qualityClips to test deinterlacing performanceSamples of different video and audio codec'sAll patterns created at 1080p in native colour space using custom softwareBy Spears & MunsilBlu-ray EditionStacey Spears and Don Munsil, who created the highly-regarded DVD Player BenchmarkTM and Progressive Scan Shootout at Secrets of Home Theater and High Fidelity®, have applied all their technical wizardry to this Blu-ray test and evaluation disc. "The test patterns on this disc represent the current state-of-the-art. They are cleaner and more accurate than the test patterns found on previous discs. There are a lot of subtle details that go into making them as mathematically perfect as possible, especially to ensure that they retain all their precision after lossy encoding. We have built proprietary tools to generate patterns and a custom encoder that preserves much more detail.
