HDMI 1.4 Announced

May 29, 2009

It’s official. According to, the designers of the HDMI interface commonly used by HDTVs this week announced HDMI 1.4, which will add Ethernet support to the HDMI cable as well as a few other improvements. The High-Definition Multimedia Interface will now support 100-Mbit Ethernet, and will not require a separate cable. The new cable spec will also support the 4k video standard, including support for 4096 x 2160 video.

"The HDMI specification continues to add functionality as the consumer electronics and PC industries build products that enhance the consumer’s HD experience," said Steve Venuti, president of HDMI Licensing, LLC, in a statement. "The 1.4 specification will support some of the most exciting and powerful near-term innovations such as Ethernet connectivity and 3D formats. Additionally we are going to broaden our solution by providing a smaller connector for portable devices and a connection system specified for automobiles, as we see both more and different devices adopting the HDMI technology."

The spec itself will be available for download from the HDMI Web site on or before June 30.

HDMI 1.4 will have a 19-pin connector head that is 50 percent smaller than current HDMI cables. You also shouldn’t expect any devices based on the new standard to hit store shelves any time soon. HDMI Licensing is set to release the new specifications to manufacturers between now and June 30. That means we probably won’t be seeing any 1.4-enabled toys until some time in 2010.
