Oversampling at the 216 MHz frequency of the DVP-NC555ES and
DVP-CX777ES is even more dramatic
The DVP-NC555ES and DVP-CX777ES go further still, all the way to an
amazing 216 MHz oversampling. This corresponds to 8x oversampling for
progressive scan, 16x for interlaced playback. It's the most powerful
oversampling that Sony has ever built into a DVD player. You get superb clarity
with the effective suppression of video noise, while enjoying the full video
bandwidth for breathtaking picture detail.
Noise Shaped Video™ circuitry (all models)
While 108 MHz and 216 MHz oversampling deals with noise outside the
video frequency range, another circuit reduces noise within the frequency range.
That's important because the perceived transparency and depth of the video
image depends on controlling noise. Sony's D/A converter uses Noise Shaped
Video circuitry to shift noise from inside the visible frequency range to outside.
Even though the overall noise level remains the same, the perceived noise is
dramatically reduced. What's more, once shifted, the out-of-band noise is further
suppressed by the analog filter. The result is reproduction without flecks or
specks of unwanted color. You'll see a video picture that's vibrant, deep,
transparent and clean.
