HDMI/DVI to HD-SDI stand-alone video converter and mixer

The VMIX-HDMI2SDI-IS is an intelligent stand-alone scan converter with video mixing capabilities. The VMIX-HDMI2SDI-IS accepts High definition HDMI/DVI input signal and converts it to HD-SDI.

The VMIX-HDMI2SDI-IS accepts HDMI/DVI signalling over a single flat flex connector. The HDMI/DVI is captured, scaled, converted, and output as HD-SDI on a 75 Ohm MCX connector. A secondary HD-SDI output is available as an option. The VMIX-HDMI2SDI-IS features high-speed digital signal capture, video scaling, frame rate conversion and timing generation for conversion between display modes. There is also an optional KLV meta-injection on the HD-SDI output.

The VMIX-HDMI2SDI-IS also features a PAL/NTSC/RS-170 video input that can be mixed with the HDMI input and displayed on the HD-SDI output e.g. in a picture-in-picture mode.

The VMIX-HDMI2SDI-IS is an intelligent stand-alone device that does not require a host CPU or other driver software.  For mechanical convenience, the module can be mounted on a PCI104 stack without consuming host CPU resources
