The 1T-C2-520 DVI-I to SD/HD-SDI Converter from TV One is a scaler that converts DVI-D 720p or 1080i HD signals to HD-SDI for broadcast and professional use. It will also convert YPbPr or RGBHV signals to HD-SDI or standard analog YUV signals at 525i or 625i to SD-SDI.

Since no scaling is performed within the unit, the input vertical rate used must be exact. The unit can be controlled via front-panel buttons, an on-screen display, or RS-232 connectivity. It's small footprint makes it well suited for desktop use, although it can be placed in a rack by using a separately available rackmount kit.
