The next-generation of HDMI interface has been rubber-stamped by the HDMI Licensing consortium. HDMI 1.4 isn’t just a small upgrade either. There are several significant improvements to the technology, including integrated data connectivity and support for 3D. Here’s an excerpt of my recent article:

1. HDMI 1.4 features an integrated Ethernet channel

The new version of HDMI adds a bi-directional IP data channel to allow devices to send and receive data at full Ethernet speeds (i.e. up to 100Mbps). This basically eliminates the need for a separate Ethernet cable and enables web-capable devices (with HDMI 1.4 connectors) to share their Internet connection with other HDMI gadgets. For example, an HDMI 1.4-equipped amp could act as the Internet hub of a home cinema system, sharing its broadband access with a connected TV or set-top box.

2. There’s support for dual-stream 1080p 3D

HDMI 1.4 defines several 3D formats for HDMI-enabled devices, including ‘frame alternative’, ‘line alternative’ and ‘field alternative’ methods, ‘Side by side’ methods (full and half) and ‘2D plus depth’ methods. The new specification is also capable of handling dual-stream 3D resolutions up to 1080p. Having already made an impact on the big screen, 3D is arguably the ‘next big thing’ in home entertainment. BSkyB has recently announced its intention to launch a 3D channel, while 3D gaming experiments have already been conducted on the PC and PS3.
