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.
