This is made possible by the 4K High-Precision Chroma Processor - The technologies for Panasonic's unique 4K High-Precision Chroma processing come directly from the Panasonic Hollywood Laboratory, the centre of Blu-ray Disc research and development. In this process, 4K colour signals (4:2:0) are interpolated into 4K (4:4:4) using a multi-tap chroma process, making them appear even more natural and deeper.
