enhancing the image quality during normal and trick play
operations. Progressive interpolation, sharpness and brightness
equalization are implemented with these output filters. When
using pause, fast forward, or fast reverse, the progressive
interpolation filter provides a high quality image output, without
displaying annoying artifacts. The ZR36730 supports video edge
enhancement and brightness control via programmable filter
coefficients, giving it the flexibility to control the sharpness,
intensity, and dynamic range of the image.
