HDMI 1.4 specs announced; include 3D and 4K x 2K resolution support
HDMI Licensing, LLC unveiled what we can expect from the upcoming HDMI 1.4 standard today and it's some pretty impressive stuff.
First, an extra data channel will be added to HDMI cables for bi-directional communication over Ethernet. Second, an Audio Return channel will be able to send sound signals to any A/V receiver enabling home theater buffs to do away with a cable. Third, 3D over HDMI lists standard 3D formats enabling the standardization of inputs/outputs for 3D home theater devices. Fourth, 4K x 2K resolution support will enable four times the pixels of current 1080p resolution. 3840×2160 at 24Hz/25Hz/30Hz and 4096×2160 at 24Hz resolutions will all be supported. Fifth, sYCC601, Adobe RGB and AdobeYCC601 color spaces designed for digital cameras will be supported. Sixth, a new micro HDMI connector with 19-pins will be added supporting up to 1080p resolution from portable devices. It'll be roughly half the size of the current mini connector. Seventh, an automotive connection specification will be added specifically for HD content transmission to automotive entertainment systems.
While the new specs are great, they also mean that HDMI cables will become more confusing. Namely that there will be 5 to choose from:
- Standard HDMI Cable - supports data rates up to 1080i/60;
- High Speed HDMI Cable - supports data rates beyond 1080p, including Deep Color and all 3D formats of the new 1.4 specification;
- Standard HDMI Cable with Ethernet - includes Ethernet connectivity;
- High Speed HDMI Cable with Ethernet - includes Ethernet connectivity;
- Automotive HDMI Cable - allows the connection of external HDMI-enabled devices to an in-vehicle HDMI device.
