4K PLAYBACK EXPLAINED

COMPRESSION STANDARDS The evolution of compression technology JPEG MPEG-2 MPEG-4, H.264, AVC (Advanced Video Coding) H.265, HEVC (High-efficiency Video Coding)

4K RESOLUTIONS TV & Cinema 4K 4K TV resolution is 3840 pixels x 2160 lines

Aspect ratio 16:9

This is the resolution supported by UHD / 4K displays in the consumer TV and commercial panel markets.

UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.

Cinema 4K film projection resolution is 4096 pixels x 2160 lines Aspect ratio 17:9

This is the native resolution for DCI-compliant 4K digital projectors and monitors.

Pixels are cropped from the top or sides depending on the aspect ratio of the content being projected.

Also twice the horizontal and vertical resolution as the DCI 2K format, with four times as many pixels overall.

4K PLAYBACK – STANDARDS Optimal playback of native 4K content on a 4K UHD display New 4K Standards True Native 4K: 3840x2160 resolution @ 60fps frame rate

H.265 HEVC (high efficiency video coding): enables delivery of high-quality 4K content at about the same file size and data rate as HD content at H.264

HDMI 2.0: only the new HDMI 2.0 output can support 60 fps playback

4K PLAYBACK – ENCODING Process to deliver native 4K video @ 60fps

Video Encoding Native 4K (3840x2160) video file should be encoded to the new

compression format H.265 in order to playback at 60 fps H.265 HEVC (high efficiency video codec) enables delivery of high-quality

4K content at about the same file size and data rate as HD content at H.264

H.265/HEVC – THE NEW STANDARD The importance of proper video compression Smaller File Advanced compression efficiencies

from larger block sizes Up to 50% efficiency gain in coding

translates to lower bitrates

Better Picture Quality Increased intra prediction modes

and higher encoding computation allows for soft blur effect rather than macro-blocking

4K PLAYBACK – VIDEO FILE Process to deliver native 4K video @ 60fps

4K Video File Resolution: H.265 encoded 4K (3840x2160) video file Frame rate: playback at 60 fps

4K PLAYBACK – DECODE Process to deliver native 4K video @ 60fps

Decoding Player must be able to decode an H.265 4K (3840x2160) encoded file Player must be able to decode at a data rates of 60 fps

4K PLAYBACK – OUTPUT Process to deliver native 4K video @ 60fps Output to 4K Display Player must have HDMI 2.0 output to enable playback

at a frame rate of 60 fps HDMI 1.4a only supports 30 fps
