Noise Shaped Video™ circuitry

While 216 MHz sampling 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.

Noise Shaped Video and the higher 216 MHz sampling frequency work together to cut video noise for improved transparency and clarity.

both luminance and color difference channels.

The benefit of the 216 MHz sampling rate is delivered by the Super Sub Alias Filter circuits. In comparison to most previous designs, these filters are now far more effective for two powerful reasons. First, the 216 MHz sampling rate is higher. Second, while some previous designs deployed Super Sub Alias Filter circuitry on the black-and-white (luminance) channel only, the DVP- NS9100ES uses these filters on all three video channels: luminance (Y), blue
