The SC1120 3G-SDI to HDMI & AV Scaling Converter from AVMATRIX is suitable for broadcasting and AV post production applications. It converts an SDI signal to HDMI and AV signals at the same time. The output is suitable for pass-through or up/down scaling and frame rate conversion. De-interlacing function and seamless conversion can also be supported to avoid jitter. It also features AES/EBU or analog audio embedding and de-embedding.

The converter can automatically switch to the redundant SDI input to avoid the loss of video signal in case of an accident. This makes it suitable for studios, live shows or outdoor live events. Meanwhile, re-clocked SDI output ensures a long-distance transmission without loss of signal quality. All the functions can be easily set by built-in DIP switches or remotely controlled using software when connected to a PC via USB.
