Ran across the Miranda DT-4101 Digital Theater Pre-Processor at http://www.miranda.com/DT-4101.htm and was curious if anyone here has ever used this or anything similar?
Here's some of the key verbage from their website:
Large display applications have seen tremendous image quality improvements in recent years due to to improved projection technology and the availability of high-quality, up-scaling devices (e.g. line doublers, line quadruplers and scalers). The DT-4101, which is typically installed before the up-scaler or projector, is designed to radically reduce artifacts and maximizing signal quality. Pre-processing is important because up-scaling and large displays tend to magnify the effects of noise and other artifacts.
Top-Quality, 10-Bit Conversion and Processing
The DT-4101 accepts a large number of different video formats and provides conversion from these various formats to a common output format. Featuring multiple inputs of Composite Analog (NTSC or PAL), S-Video, Component and Serial Digital Component (SDI) the DT 4101 provides easy, seamless switching among inputs. Designed to guarantee the best possible signal quality, the DT-4101’s internal conversion is based on the same 10-bit processing featured in Miranda’s highly acclaimed broadcast and post-production converters.
MPEG-2 Artifact Reduction
Of all the signal processing built into the DT-4101, the single most important block is Miranda’s MPEG artifact reduction system (MARS). Based on new and advanced algorithms, MARS processing dramatically reduces an impairment commonly referred to as mosquito noise, which is introduced by MPEG compression and decompression. Mosquito noise appears around the edges of persons and objects within a video signal that has been compressed and decompressed and is particularly objectionable when the image is up-scaled and projected on a large-screen display. MPEG artifact reduction is now considered an essential function due to the wide deployment of MPEG-2 for Digital Television (DTV), Satellite TV (DBS), Digital Video Disk (DVD), Digital Video Tape (e.g. DV and DVHS), Personal Video Recorders (PVR) and new broadband digital video services (e.g. DSL and digital cable).
Adaptive Detail Enhancement
Another important DT-4101 feature is its adaptive detail enhancement, which, unlike linear-based detail enhancement processors, uses adaptive circuitry to detect the image zones where more or less detail is required. This adaptation is carried out pixel-by-pixel in real time. Detail enhancement helps to reduce the softening effect of up-scaling and large-screen projection.
