Tech Specs
The Densité Series UDC-3901 is a compact utility grade 3G/HD/SD up/down/crossconverter with video, audio and metadata processing. It offers up/down/crossconversion, with simultaneous 3G, HD and SD outputs. The processor performs all the up/down/crossconversion, color space and aspect ratio conversion needed to maintain the chosen output formatting, irrespective of whether the input is 3G (Level A or B), HD 1080i, HD 720p or SD. To ensure that up/downconverted television is presented in the correct aspect ratio when aired, the UDC-3901 supports AFD (Active Format Description) SMPTE-2016.
