Sony today announced an upgrade on its long-evolving Digital Reality Creation TV picture improvement technology. First introduced in 1997, this new iteration called DRC Multifunction v2.5.has been developed to create 1080p HD images from any type of digital signal input.
It extends the basic DRC concept, which centers around improving the resolution of various input signals based on interpolation (clever guessing), to make better use of the latest high definition LCD panels. The last significant change to DRC happened back in 2004.
With version 2.5, Sony engineers have utilised sophisticated Digital Mapping techniques to reduce noise and improve subjective resolution. The company says the technology “can create more real, stable HD signals by improving the vertical resolution of 720p and 1080i sources.” The technology will also improve lower resolution material already upconverted to 1080i (typically from DVD players with upscaling). According to Sony: “These signals have different characteristics from the original 1080i HD signals, but they can also be optimized by DRC-MFv2.5.” The technology will debut in the next generation of Sony BRAVIA LCD TVs.
