Sunnyvale, Calif. — The licensing agency for the HDMI digital connection standard formally unveiled Thursday the HDMI version 1.4 specifications, which among other things will enable bi-directional communication allowing networking capabilities with Ethernet devices, and upstream audio transmissions.
HDMI 1.4 includes an HDMI Ethernet Channel (HEC) enabling data transfers of up to 100Mbps between supported connected devices, said the HDMI LLC, the agent responsible for licensing HDMI specifications.
The bi-directional connection allows a broadband-connected television using its HEC-enabled HDMI port to provide Internet connection sharing with another HEC-enabled device, such as a game console or DVR.
The HEC will require new HDMI 1.4 cables, which will be offered in two performance levels of low- and high-data rates.
