Professional Alternative Content Processing for Digital Cinema

Alternate Content Processing for Digital Cinema is a uniquely demanding task which requires the best possible scaling and image processing if the viewer experience is to be maximized.  The large screen size and dark viewing environment mean that noise and picture softness which would not be noticed on a normal projector or TV screen suddenly becomes apparent to the viewer.

The situation is exacerbated because Alternate Content feeds are often not of the same quality as true digital cinema content, sometimes the alternate content comes from a professional source, sometimes from a consumer-grade source.  Often it has been mastered or recorded in standard definition.  Even feeds in HD format often contain significant noise in dark areas and areas of saturated color and many images have a lack of sharpness when shown on a large movie screen.

Using a general purpose scaler not specifically optimised for Digital Cinema simply makes the image larger, it doesn't improve the quality of the image.

To truly generate a picture of suitable quality for Digital Cinema viewing requires a video processor up to the task, for which PVProHD-DC and HQView-400DC have been especially optimised.

PVProHD-DC is a state of the art alternate content processor which uses real-time SIMD DSP-based software image processing techniques to effectively re-master the alternate content image in real-time.  As well as excellent scaling using 1024-tap scaling filter and superb de-interlacing and aspect ratio conversion, PVProHD-DC performs per-pixel motion adaptive noise reduction to significantly reduce image noise and grain in HD and SD images without causing loss of detail or motion blur.  PVProHD-DC can also enhance image clarity through its detail enhancement algorithms and provides a real-time unsharp mask which is able to make near-HD quality from SD sources.  PVProHD-DC uses true post-production grade image processing algorithms as used in the production of movies, ensuring best in class picture performance always.

HQView-400DC is a cost effective Alternate Content Processor for budget conscious installations.  It provides great scaling and de-interlacing and SD noise reduction, as well as detail enhancement and aspect ratio conversion of common sources.

PVProHD-DC outputs the Digital Cinema Alternate Content standard format of 2048x1080p so is fully compatible with the alternate content input of leading Digital Cinema 4K and 2K projectors from many manufacturers.  HQView400DC outputs 1920x1080p which is also compatible with most leading digital cinema projectors. In particular PVProHD-DC and HQView-400DC have been tested and optimised for use with the Sony CineAlta range of 4K Digital Cinema projectors.
