HQV Benchmark 2.0 is an updated version of the original tool and it consists of various video clips and test patterns which are designed to evalute motion correction, de-interlacing, decoding, noise reduction, detail enhancement and film cadence detection.
There are two versions of the program, standard definition on DVD and high definition on Bluray. As our audience will be concentrating on HD content so will we.
This has a total of 39 video tests which is increased from 23 in the original and the scoring is also up from a total of 130 to 210. As hardware and software gets more complicated, the software has been tuned to make sure we can thoroughly maximise our analysis.
When AMD released the Catalyst 10.6 drivers back in June of this year they made additions to the settings that deal with video playback quality. They have added settings such as Mosquito Noise Reduction and De-blocking to help to provide the best video quality possible. Many people will wonder what these features are for so we have added a definition of these terms to help understand their relevance.
Definition of: mosquito noise:
A distortion that appears near crisp edges of objects in MPEG and other video frames that are compressed with the discrete cosine transform (DCT). It occurs at decompression when the decoding engine has to approximate the discarded data by inverting the transform model. The mosquito noise appears as random aliasing in these areas and requires sophisticated detection circuits to eliminate it. As TVs get larger, mosquito noise and other artifacts become more noticeable.
Deblocking filter (video)
A deblocking filter is applied to blocks in decoded video to improve visual quality and prediction performance by smoothing the sharp edges which can form between blocks when block coding techniques are used. The filter aims to improve the appearance of decoded pictures.
