Interworld Electronics introduces the ST-IPHDMI HDMI video over IP extenders from Network Technologies Inc.
HDMI over IP extenders consist 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-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 multiple transmitters, a managed network switch with VLAN/IGMP support is required, which 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 which signal is being watched at each location.
The ST-IPHDMI HDMI over IP transmitters support HDTV resolutions to 1080p and computer resolutions to 1920x1200.
Compliant with HDMI 1.3 and HDCP high definition TV standards, ST-IPHDMI HDMI over IP extenders also support linear PCM and Dolby Digital 5.1 audio through HDMI compatible TVs or audio receivers.
