MultiDyne introduces portable 3Gb/s HDMI signal distribution

Enabling high bit rate signals to reliably travel long distances, MultiDyne has introduced its new HD-Multi-Link. The lightweight unit is designed for the drop and repeat optical distribution of SDI and HD-SDI TV signals on a single mode fiber-optic cable. The HD-Multi-Link is fully compatible with SMPTE-compliant HD-SDI products such as the company’s HD-1500 and HD-3000 HD-SDI fiber-optic links, and is available in a 3Gb/s and a low-cost 1.5Gb/s version.

Applications for the new HD-Multi-Link include production monitoring and distribution; announcer booth, event, press, pool and stadium house feeds; campus distribution and applications that require the optical drop and repeat of HD-SDI with HDMI monitoring capability.

HD-Multi-Link with electro-optical DA provides a midpoint fiber distribution breakout box for up to three copper HD-SDI outputs with a signal quality of up to 3GB. An optical input and optical output transports the signal to the next device, with an HDMI output for local video and audio monitoring. HD-Multi-Link supports audio and data that has been embedded externally and provides for audio de-embedding from the HD-SDI stream for output on HDMI, or on separate RCA connectors. Three re-clocked electrical outputs enable additional breakout locations along the distribution path.

The HD-Multi-Link supports several SMPTE standards, including SMPTE 424M 3G–SDI, SMPTE 292M 1.485Gb/s and SMPTE 259M 270Mb/s.

The highly the portable HD-Multi-Link features a rugged configuration and is rack-mountable. It is also available with ST, LC or FC optical connectors and includes a 5 VDC in-line power supply. An external battery from 5 to 16 VDC can also power it.
