12. SPEED RATING
What does the “Speed Rating” of HDMI® cables actually measure?
The speed rating determines a cable’s ability to transfer large amounts of data
at certain predetermined time intervals usually measured in Gigabits per Second (Gbps).
HDTV Set Top Box – 1080i / 8-bit Color – 2.23 Gbps
Advanced Gaming Station (xBox360/PS3/Wii) – 1080p / 8-bit Color – Gbps
HDMI Ver. 1.3a – 1080p / 12-bit Deep Color – Gbps
Blu-Ray Profile 1.3 – 1080p / 14-bit Deep Color – Gbps
Blu-Ray Profile 2.0 – 1080p / 16-bit Deep Color – 8.91 Gbps
HDMI Ver. 1.4a – 1440p+ / 16-bit Deep Color – 10.2 Gbps
HDMI Ver. 3D, 4K and beyond
Guaranteed Standard Speed
4.95 Gbps
Standard Speed cables that will pass Blue-Ray’s 1080p
Guaranteed High Speed
10.2 Gbps
Note: New Longer Length Integrator (CS1) and Caliber Series (10 to 15 meter) will do 1080p Standard Speed. They are certified up to but not above 10.2 Gbps (High Speed)

15. Note: What HDMI.org did not foresee was that components would be connected by Wi-Fi and not have to be physically connected at all.

16. The new HDMI spec has added the optional HDMI Ethernet and Audio Return Channel (HEAC). This feature allows:
Internet connection sharing among devices
Device to device content distribution
Current and future IP-based applications (D-NLA, UPnP, IPTV etc)

Ethernet Wiring
The 5-volt power conductor must be built to minimize resistance.
The shielding and dielectrics need to do their jobs better than ever.
Every twisted pair conductor needs to be accurately constructed in the correct gauge.
In analog cables, performance depends on design. The digital HDMI cable is no different.

The Hardware side…
Current or Standard HDMI
It is recommended that you label input and output that support the HDMI Ethernet Channel an/or the Audio Return Channel. HDMI Licensing, LLC recommends that such ports be labeled as follows:
Ports that support the Audio Return Channel should be labeled “ARC”
Ports that support the HDMI Ethernet Channel should be labeled “HEC”
Ports that support both the Audio Return channel and the HDMI Ethernet channel should be labeled “ARC + HEC”
Note: Don’t hold your breath waiting to see Components featuring HEC; I will explain…
