In the last two posts I have provided an overview of the new HDMI Version 1.4 standard. In
this post I will focus in on what I see as a key future looking feature of the standard, the “Ethernet Channel”.
With more and more entertainment devices IP enabled, having the ability to connect to the internet, cabling is becoming more and more and issue. Currently each device that connects to the internet requires its own unique internet connection as well as a connection back to the viewing (TV) device.
The implementation of the HDMI Version 1.4 standard now allows HDMI Version 1.4 enabled devices to share the internet connection as well as traditional HDMI Audio / Video signaling in one cable.
This helps to further simplify your entertainment systems by eliminating the need for separate Ethernet cables.
To maximize the value of HDMI Version 1.4 and maximize your functionality you will need to make sure your devices are HDMI 1.4 Ethernet Channel capable. Over the next year or so more and more devices will come designed to this standard as a matter of course, for now it is found in most high end devices.
Again the key benefits of the HDMI Version 1.4 Ethernet Channel are:
- Consolidation of HD video, audio, and data in a single cable
- Enablement of high speed bi-directional communication
- IP-based applications over HDMI
- Transfer speeds up to 100 Mb/sec
