This is a 5 Channel Rack Mounted 3G-SDI Hum Eliminator! The Allen Avionics 3G-SDI Hum eliminators are famous for reduce jitter caused by induced noise effects for the High Definition broadcast chain. Unstable signal sources, poor re-clocking systems and cable attenuation can be the demise of digital signals. 3G-SDI Serial Digital signal transmissions at 2.970Gbps over a cable contain a range of low to high frequencies like analog signals and are subject to analog-type distortions like induced noise as well as unique digital distortions related to sampling and quantizing. These distortions may result in a variety of visible impairments. Unlike analog signals, the digital signals do not degrade gracefully and are subject to a cliff effect. Using the Allen Avionics 3G-SDI Hum Eliminator you can eliminate the potential for this kind of data loss, see Outgoing Video. The model 3G-SDI Hum Eliminator supports the four transmission rates up to 2.970Gbps and supports SMPTE 424m.
FYI Here is a brief comparison of the differences between 3G SDI vs HD SDI:
HD SDI optical terminal appliances are designed and manufactured for serial digital optical transmission devices with increased reliability and performance in the television field. Meanwhile, the 3G SDI digital video optical terminal equipment is an enhanced edition of HD SDI.
HD-SDI signal formats range from 19.4 Mbps to 1.485 Gbps. 3G SDI signal formats vary from 19.4 Mbps to 2.97 Gbps. HD SDI is the common name for the 1.485Gbps serial interface. SMPTE adopts SMPTE424M, a new standard that increases the SDI data rate two times to 2.97 Gbps, which is 3 Gbps (3G) SDI.
