HDMI Forum today announced the release of Version 2.0 of the HDMI Specification. This latest HDMI Specification offers a significant increase in bandwidth (up to 18Gbps) to support new feature such as 4K@50/60Hz (2160p); 32 audio channels as well as up to 1536kHz audio sample frequency; as well as dynamic auto lip-sync and extensions to CEC. The complete Version 2.0 of the HDMI Specification is available to Adopters on the HDMI Adopter Extranet and HDMI Licensing will host a press conference to discuss the new features of the HDMI 2.0 Specification at IFA 2013 in Berlin on Friday, September 6 at 12:00pm in the TecWatch Forum area of Hall 11.1.
HDMI 2.0 is fully backwards compatible with earlier versions of the HDMI specifications, furthermore the HDMI 2.0 does not define new cables or new connectors. Current High Speed cables (Category 2 cables) are capable of carrying the increased bandwidth. The HDMI 2.0 Compliance Test Specification (CTS) is expected to be released before the end of 2013.
The good news here is that HDMI 2.0 is probably going to be the thing that we needed 3D HDTV manufacturers to finally add support for 3D modes with higher refresh rate such as 1080p at 50/60Hz per eye, unlike the currently available 1080p 24Hz 3D mode which is the maximum used in the devices equipped with HDMI 1.4. With that said however the HDMI Forum has still not revealed what the new HDMI 2.0 Specification will support in terms of 3D features, but thanks to the increase of the maximum supported bandwidth and the presence of support of 4K resolution with 60Hz refresh rate we should also get 1080p 60Hz for 3D mode as well. Though we are probably not going to see new 3D HDTV sets using the new HDMI 2.0 interface earlier than the spring of 2014, this is still good news.
