Preliminary

4K / 60p

High speed display in 60 frames per second of 4K video (3,840 x 2,160 pixels – Ultra HD), which has four times the resolution of Full Hi-vision, for highly detailed videos with extremely smooth movement.

10-bit gradation

Previous Blu-ray Discs displayed the color signals (Y, Cb, Cr) in 8-bit gradation each (256 gradations). By expanding this to 10-bit gradation each (1,024 gradations), even minute signals can be faithfully reproduced to realize richly textured video.

High Dynamic Range

A technology that drastically expands the brightness peak from the previous 100 nit to 1,000-10,000 nit, marking a significant leap in the dynamic range of the picture. Bright light sources (e.g. lights or rays of the sun) and reflected light (from metal or water) that up to now were difficult to display can now be shown in rich textures.

BT.2020 wide color gamut

Compliant with the ITU-R BT.2020 wide color gamut signal formulated for 4K/8K broadcasting. Enables vividly rich coloration not previously possible on Blu-ray discs (BT.709 standard).

HEVC (H.265) / 100Mbps

Support for the highest 100Mbps video signal using the latest high-efficiency video compression technology. Compression efficiency and high bit rate far beyond previous Blu-ray discs (MPEG-4/AVC (H.264), maximum 40Mbps) enabling outstanding playback of high quality video with 4K/60p/10bit, High Dynamic Range, BT.2020, etc.
