Interworld Electronics has released the ST-IPHDMI HDMI Over IP Extender from Network Technologies Inc. Each HDMI Over IP Extender consists of a local unit that connects to an HDMI source, and a remote unit that connects to an HDMI display.

In point-to-point configuration one ST- ST-IPHDMI-L transmits digital video and audio signals to one ST-IPHDMI-R receiver up to 333 feet away using a single CAT6/7 cable. Point-to-point connections also allow optional IR control of the video source from the remote display location. In a multi-cast configuration one ST-IPHDMI-L transmits HDMI signals to more than one ST-IPHDMI-R receiver using VLAN isolation via a managed network switch.

Standard LAN switches can only support one transmitter. To support for multiple transmitters a Managed Network Switch with VLAN/IGMP support is required. I this case the managed switch must support port based IEEE 802.1Q VLAN, IGMP, and permit duplicate IP addresses across the VLAN domains. Each VLAN then acts as a separate HDMI Over IP Channel on the network. A PC can be used to access the built-in HTTP Interface of the managed network switch to control what signal is being watched at each location.

The ST-IPHDMI supports HDTV resolutions to 1080p and computer resolutions to 1920x1200. The ST-IPHDMI is compliant with HDMI 1.3 and HDCP high definition TV standards and also supports Linear PCM and Dolby Digital 5.1 audio through HDMI compatible TVs or audio receivers.
