HDMI Ethernet Channel
The HDMI 1.4 specification adds a data channel to the HDMI connection, enabling high-speed, bi-directional communication. Connected devices that include this feature can send and receive data via 100Mb/sec Ethernet, making them instantly ready for any IP-based application. The HDMI Ethernet channel allows internet enabled HDMI devices to share an internet connection via the HDMI link with no need for a separate Ethernet cable. It also provides the connection platform that will allow HDMI-enabled components to share content between devices.
The 1.4 version of the specification defines common 3D formats and resolutions for HDMI enabled devices, enabling gaming and other 3D video applications. The specification standardizes the input/output portion of the home 3D system, facilitating 3D resolutions up to dual stream 1080p.
4K Resolution Support
The new specification enables HDMI devices to support extremely high HD resolutions, effectively four times the resolution of a 1080p device. Support for 4K allows the HDMI interface to transmit digital content at the same resolution as the state-of-the-art Digital Cinema systems used in many movie theaters.
