Ixia and Agilent Offer HDMI Ethernet Channel Test

Ixia released an HDMI Ethernet Channel networking test. The solution combines Ixia's IxN2X traffic generator and Agilent's HDMI Ethernet Channel (HEC) and Audio Return Channel (ARC) physical layer test.


An estimated one billion HDMI-enabled devices expected to be in use by 2010. The latest version of the HDMI specification, version 1.4, adds high-speed Internet Protocol networking to the HDMI cable and connected devices over the HDMI Ethernet Channel. Compliance testing to the HDMI 1.4 specification will take place at Authorized Test Centers (ATCs) located worldwide.

http://www.agilent.comNew capabilities are being built into the High-Definition Multimedia Interface (HDMI) specification, including networking capabilities with Ethernet connectivity and an Audio Return Channel to enable upstream audio connections via the HDMI cable. Specifically, these enhancements will include:

HDMI Ethernet Channel -- the HDMI 1.4 specification will add a data channel to the HDMI cable and will enable high-speed bi-directional communication. Connected devices that include this feature will be able to send and receive data via 100 Mb/sec Ethernet, making them instantly ready for any IP-based application. The HDMI Ethernet Channel will allow an Internet-enabled HDMI device to share its Internet connection with other HDMI devices without the need for a separate Ethernet cable. The new feature will also provide the connection platform to allow HDMI-enabled devices to share content between devices.


Audio Return Channel -- the new specification will add an Audio Return Channel that will reduce the number of cables required to deliver audio upstream for processing and playback. In cases where HDTVs are directly receiving audio and video content, this new Audio Return Channel allows the HDTV to send the audio stream to the A/V receiver over the HDMI cable, eliminating the need for an extra cable.


3D Over HDMI The 1.4 version of the specification will define common 3D formats and resolutions for HDMI-enabled devices. The specification will standardize the input/output portion of the home 3D system and will specify up to dual-stream 1080p resolution.


4K x 2K Resolution Support: the new specification will enable HDMI devices to support high-definition (HD) resolutions four times beyond the resolution of 1080p. Support for 4K x 2K will allow the HDMI interface to transmit content at the same resolution as many digital theaters. Formats supported include 3840x2160 24Hz/25Hz/30Hz and 4096x2160 24Hz.


Expanded Support For Color Spaces -- HDMI technology now supports color spaces designed specifically for digital still cameras. By supporting sYCC601, Adobe RGB and AdobeYCC601, HDMI-enabled display devices will be capable of reproducing more accurate life-like colors when connected to a digital still camera.


Micro HDMI Connector -- the Micro HDMI Connector is a significantly smaller 19-pin connector that supports up to 1080p resolutions for portable devices. This new connector is approximately 50% smaller than the size of the existing HDMI Mini Connector.
