HDMI 1.4 Cable Types
The HDMI Organization has released the HDMI 1.4
specification.
With this release, there are now five HDMI cable types
to choose from, each designed to meet a particular performance standard.
The HDMI Organization found that the specification numbers realated to the test
specification (1.0, 1.2, 1.3A, 1.4, etc) became confusing to the consumer
and has since mandated a standard naming convention for the different types of
HDMI cables. To help consumer and clarify cable types further, all HDMI
cable products will now be required to be labeled by cable type. The
following names signify the different types of HDMI cables: Standard HDMI Cable,
Standard HDMI Cable with Ethernet, Automotive HDMI Cable, High Speed HDMI Cable,
and High Speed HDMI Cable with Ethernet. The version number for the
specification should no longer be used. The following is a description of
the different HDMI cable types:
Standard HDMI Cable
The Standard HDMI cable is designed to handle
most home applications, and is tested to reliably transmit 1080i or 720p high
definition (HD) video resolutions that are currently associated with most cable
and satellite television, digital broadcast HD, and DVD players.
Standard
HDMI Cable with Ethernet - This cable type offers the same video performance as
the Standard HDMI Cable, including 720p or 1080i video resolutions, plus an
additional, dedicated data channel, known as the HDMI Ethernet Channel (HEC),
for device networking. HEC functionality is only available if both the
source and sink devices are equipped with HEC functionality.
High Speed HDMI Cable
The High Speed HDMI cable is designed and
tested to support advanced video resolutions such as 1080p and beyond. In
addition, the High Speed HDMI Cables will support advanced display technologies
such as 4K, 3D, and Deep Color. This is the recommended cable type to use
for these advanced technologies and for 1080p devices, such as Blu-ray disc
players.
High Speed HDMI Cable with Ethernet
This cable type offers the same performance
(1080p and greater resolutions) as the High Speed HDMI Cable, plus an
additional, dedicated data channel, known as the HDMI Ethernet Channel (HEC),
for device networking. HEC functionality is only available if both the
source and sink devices are equipped with HEC functionality. HEC connected
devices that include this feature can send and receive data via 100 Mb/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.
Automotive HDMI Cable
This HDMI cable is designed for internal
cabling of vehicles equipped with onboard high definition video systems.
These cables can withstand the unique stresses (vibration and temperature
extremes) present in motoring environments. Using the Automotive
Connection System, car manufacturers now have a viable solution for HD
distribution within a vehicle.
