The UDC is a broadcast quality Up/Down/Cross Mini-Converter which can convert between 3G, HD, and SD video formats. Using the same AJA industry leading conversion technology as in our FS2, the UDC provides very high quality conversions at a low price. I/Os include 3G/HD/SD SDI input and output, HDMI output, and 2-channel RCA style audio output. The UDC can be controlled by local DIP switches with additional control available via USB and AJA's MiniConfig application. A Reference input allows the UDC to be locked to a local reference.
