Problems here may result in low-level colour pictures that lack contrast. Below average Upper frequency response As with TVs and VCRs, this is the highest luminance frequency that can be resolved. The higher the figure the better. We assess both composite and S-video outputs. This test puts a precise figure on this leakage.
All electronic systems generate unwanted noise.
It's not so much of a problem in the digital domain, but things are rather different when the signals are converted back into analogue. In video systems, noise is apparent as grain or low-level patterning. Although sound quality is influenced by many different parameters, audio jitter leads to a lack of musicality or a softening of the bass amongst other things. A disappointing showing, usually for a specified reason Very poor. Not recommended at all Bob Tomalski explains the technicalities behind HCC's in-depth examination of DVD players' performance.
