Specification supports 4K video and 32 channel audio

The HDMI Forum is a nonprofit association that manages the HDMI specification. Today the HDMI 2.0 specification has been officially unveiled and is available for partners to download right now. HDMI 2.0 promises significantly increased bandwidth allowing new features.

HDMI 2.0 supports bandwidth of up to 18 Gbps. That gives the specification the bandwidth to support 4K 50/60 resolution video -- that is four times the clarity of standard 1080p/60 video. HDMI 2.0 also supports 32 audio channels along with dynamic auto lip-see and extensions to CEC.

HDMI 2.0 is backwards compatible with earlier versions of HDMI, and perhaps the best news is that HDMI 2.0 doesn't require new plugs or new cables. Existing high-speed category two cables are already capable of carrying the increased bandwidth provided by HDMI 2.0.

The HDMI 2.0 specification is available for adopters to download via the HDMI Adopter Extranet. A press conference will be held to discuss the new features of HDMI 2.0 at IFA 2013 in Berlin this Friday.

Check out Dolby Atmos. I saw Elysium that way and it is amazing!

Yeah... But theaters aren't going to use HDMI for their audio systems in the first place. HDMI is for home theaters and otherwise consumer use.

Are you seriously suggesting that consumers will invest in complex 32-speaker systems for their living rooms, and that the number of such eccentrics significantly exceeds the number of fingers on one hand?

The previous version of the spec supported 8 audio channels, which current 7.1 home theatre systems max out. They wanted to bump it up to leave room for future use, what would YOU suggest that they set the limit to?

They had to pick something, so they likely picked a number of channels that they thought would be enough to last them into the distant future. The fact is that the 24 new audio channels require about 1.4% of the extra bandwidth capacity added by HDMI 2.0... not exactly causing a problem there.

Oh, and also... The Dolby system boasts 64 speakers because you need that many to cover the perimeter of a huge movie theater hall. When you need to pan sound across a 100'-long wall, then yeah a linear array of a dozen speakers would work better than 2.

For home use, however, all you need is to cover a living room. Even very large living rooms (or home theater rooms) have less than 1/100th of the volume of a typical movie theater hall.

Even Dolby, in its most luxury-overkill, mode wouldn't need 32 friggin' speakers to provide a perfect sound-field and accurate sound positioning down to a degree of arc over even a McMansion-style home's available space...

If only I knew this was coming I would have made my McMansion media room bigger!

Just buy your neighbor's McMansion, hollow it out and turn it into a giant media room.

You many need more than 64 speakers then, but you could split the house into 2 media rooms. A his and her set-up.
