The second, the CLD-99, was again only a minor evolution; in terms of hardware it was simply a CLD-79 but with an improved 3D comb filter that worked via the S-Video output to increase picture quality.

In order for the comb filter effect to be audible, the spectral content of the program material must be full enough within the frequency range of this moving comb filter to reveal the filter s effect.

By placing the diaphragm of the microphone capsule parallel to and facing the plate boundary provided by the microphone package, the reflected sound delay is reduced, and the resulting comb filter interference frequencies are high enough that they are outside the audible range.

In addition to the advanced comb filter, the HLD-X0 and HLD-X9 contains a red-laser pickup, which significantly reduces crosstalk and picture-noise levels compared to players with the traditional infrared laser; it can also read through all but the worst cases of laser rot and surface wear.

Thus, while the peaks and troughs of the comb filter are more or less in a linear harmonic series, there is a significant non-linear behaviour too, causing the timbre of tape-flanging to sound more like a combination of what came to be known as flanging and phasing.

Though most of the pattern is removed from PAL and NTSC-encoded signals with a comb filter ( designed to segregate the two signals where the luma spectrum may overlap into the spectral space used by the chroma ) by modern displays, some can still be left in certain parts of the picture.

The comb filter present in these players is unique and is purportedly the finest comb filter ever used in consumer A / V gear : it is still in use in Mitsubishi's top-spec CRT rear-projection television sets ( the Diamond and now defunct Platinum series sets ) and Pioneer's Elite line of rear-projection televisions.

Signals range from composite and split, to YUV and RGB . Depending upon which format is used, this can result in far higher fidelity, particularly at strong color borders or regions of high detail ( especially if there is moderate movement in the picture ) and low-contrast details like skin tones, where comb filters almost inevitably smudge some detail.
