... Page 10 of the guide compares two images that hardly look different for a test score high of 10 and 0, and in this case resembles reasonable expectations for this test...
... MPEG NR targets compression noise, is processed differently and should not be used for this test...
... This test is all about the NTSC broadcast television system, analog cable, analog RF tuners and the RF noise that can easily come from them...
... You can also reverse the test, turn the NR off on the player and turn it on for your TV if available...
... Some NR circuits offer different range levels in which case test all of them and determine which setting provides the best balance of detail versus noise suppression...
... While an NR circuit can successfully navigate the prior noise test of still images, the addition of motion will show any artifacts created by the process and may help identify what kind of NR the video processor is using...
... The roller coaster is also a convenient test for LCD pixel speed provided you turn off NR on the player and display...
... HQV Benchmark DVD on Your Player Just because a player fails some or all of these tests does not mean it will generate the same errors when playing a Hollywood movie on your player, nor would passing some of these tests qualify as high fidelity performance...
... None of the tests even relate to how the vast majority of movies are captured, processed and mastered for DVD along with how your player is designed to reproduce them...
... Missing from this disc is the same test material processed and mastered just like Hollywood does...

... On the Test Bench The very ability to inspect and view an HDMI video source goes directly against the copyright capability of the connection since the means to see it would infer a means to steal it...
... All tests were performed using Digital Video Essentials as the source material...
... Horizontal Frequency Response Luminance As noted, waveform monitoring response was useless for this test...
... Visually the player passed the continuous frequency burst test quite well for luminance...
... This pattern always has banding so the best I can state on this is high, medium or a low contrast response with high being the best and low being the worst...
... The Toshiba HD-A35 remains a reference for this test...
... Similar to the HQV Benchmark DVD it, contains similar test material for jaggies, cadence and titles...
... The OPPO DV-981HD passed many of the tests but it uses intelligent deinterlacing...
... The ABT disc image quality and some of the tests like jaggies are better implemented and delivered than the HQV Benchmark...
... Moving on to test images from DVE at 1080p I was greeted with an overall good response...
... As noticed for the color burst response test this player is lacking by comparison...
