HDMI 2.0 Is Here

HDMI 2.0 image
If you do audio for video or are planning on buying a new television, you'll want to know that an new HDMI spec has now been released. HDMI (High-Definition Multimedia Interface) is the digital interface that allows you to transfer both video and audio from one device to another with a single cable.

HDMI 2.0 will accommodate the latest 4k displays that operate at 3840x2160p at 60Hz (the standard hi-def that we mostly see is 1920x1200p60). The bandwidth is also doubled from 9Gbps to 18Gbps, and supports the upcoming new aspect ratio of 21:9.

But the exciting part for audio people is that the new spec will support up to 32 discrete audio channels with sample rates up to 1536kHz. While home theatre is just settling into 7.1, HDMI 2.0 is all set for more immersive formats.

You can find out more about the HDMI 2.0 spec at HDMI.org.

Bobby! You should know that it is 1536 kbit/s and not a sample rate of 1536 kHz.

A 16 bit/ 48 kHz stereo file has a bit rate of 1536 kbit/s.

Cheers.

Eric,
I'm well aware of the bit rate of a 48/16 file, but the spec says 1536kHz. Unless someone made a mistake on their end, I think you'll find this corroborated in other posts about HDMI 2.0 audio.

I know but we are audio guys... ;)
1536 kHz makes no sense, this must be a typo.
