Network Technolgies ST-IPHDMI HDMI over IP extender

The ST-IPHDMI HDMI over IP extender from Network Technologies 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 extender transmits digital video and audio signals to one receiver, up to 110 m 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 extender transmits HDMI signals to more than one 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. 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 which signal is being watched at each location.
