HDMI LLC, the company which licenses HDMI standards has announced the features that HDMI 1.4 will include. The latest HDMI will sport an HDMI Ethernet Channel to provide data transfer of up to 100 Mbps. It also features a bi-directional connection, which creates compatibility between the Internet functions of a broadband TV and a, HDMI 1.4 connected device, such as a gaming console.

HDMI 1.4 also includes an Audio Return Channel which eliminates the need for additional cables when broadcast audio is being directly received by HDTVs and streamed to an external amp for processing. It includes Automatic Content Enhancement, which supports future 3D technologies, dual stream 1080p resolution, and content recognition to automatically optimize output based on the content that is connected to your HDTV.

The new specification also supports resolutions 4 times the resolution of 1080p. The 4K x 2K support will allow transfer of content at the same rate as digital theaters. It can transmit 3840x2160 at 24Hz, 25Hz & 30Hz as well as 4096x2160 at 24Hz. Color space support has been increased to allow for digital cameras, specifically DSLRs.

HDMI LLC is also rolling out Micro HDMI connector support for portable devices. The 19-pin
connector is 50% smaller than the size of the current HDMI Mini connection. The full specs will be available to download starting June 30th on the HDMI LLC website, with the list of products supporting HDMI 1.4 to be released shortly thereafter.
