HDMI Cable Types
The HDMI Organization has released the latest HDMI 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 related to the test specification (1.0, 1.2, 1.3A, 1.4, 2.0, 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.
