In the next step before implementation of the newest HDMI technology in actual products, the HDMI Forum Inc. has completed and released the Compliance Test Specification (CTS) for Version 2.0 of the HDMI Specification.
The 2.0 CTS is the document by which adopters can ensure that their 2.0-enabled HDMI products are compliant with Version 2.0 of the HDMI spec. The 2.0 CTS and the HDMI 2.0 spec are available for download by licensed HDMI adopters that have signed the 2.0 addendum to the HDMI Adopter Agreement. Both documents can be found on the HDMI Adopter Extranet.
There are 12 Authorized Test Centers (ATCs) worldwide where licensed manufacturers can submit their products for compliance testing. Adopters developing products that implement any function of Version 2.0 of the HDMI Specification need to submit their products for testing at one of the 12 ATCs. Products have to pass all applicable and available HDMI 2.0 compliance tests before shipment
Launched in September 2013, Version 2.0 of the HDMI Specification offers a significant increase in bandwidth (up to 18Gbps) to support new features such as 4K@50/60 (2160p), which is four times the clarity of 1080p/60 video resolution; 32 audio channels; as well as dynamic auto lip-sync and extensions to CEC. Version 2.0 is backward compatible with earlier versions of the HDMI Specification.
