Sony Develops New High Definition Creation Technology DRC-MFv2.5


Creating real high-resolution 1080 progressive images from various types of high-definition input

Sony Corporation announced “Digital Reality Creation Multifunction v2.5 (DRC-MFv2.5)”. This has evolved from the original “DRC” video processing technology that realized the creation of real High Definition (HD) video. This new technology can create the optimal real 1080 progressive (1080p) HD images from various types of digital input available in the digital broadcast era.

“DRC” was developed in 1997 as a technology that can convert a standard television signal format to a high-definition signal format, based on the concept of establishing a higher resolution signal format from scratch. “DRC” is different from the conventional interpolation technology that generates pixels based on the linear interpolation function. It is Sony’s unique technology that can create video with high resolution and close to reality by advanced original signal processing, optimizing the correlation characteristics of standard television signals and high definition signals.

In 2004, “DRC-MFv2” evolved from the original “DRC”, as a technology that can take HD signals from a TV broadcast or high definition camera and create even higher resolution quality and real texture.

The new creation technology “DRC-MFv2.5” can realize the following features by further improvement of “Digital Mapping” to reduce noise and the creation of real HD images:

  1. Improvement of real HD signal creation to make video objects “close to real”
    “DRC-MFv2.5” can create more real, stable HD signals by further improvement of resolution, reality and visual depth creation performance, and new robust signal processing for various kinds of HD signals.
  2. Creation of sharp and real progressive signals
    “DRC-MFv2.5” can realize a big improvement of the vertical resolution and reality of high-speed video images by the direct creation of real 1080p signals from ordinary HD signals.
  3. Creation for the digital broadcast signals
    Sometimes current digital HD broadcast programs include 1080 interlace (1080i) HD signals converted from standard definition signals. These signals have different characteristics from the original 1080i HD signals. “DRC-MFv2.5” can realize the maximum performance of full HD displays by optimizing various HD signals.

This technology is planned to be sequentially adopted in high definition flat TVs such as the BRAVIA series.
