The XVP-3901-DC is a highly integrated, 3G/HD/SD downconverter and optional video/audio signal processor, which is designed to synchronize, downconvert and process 3G, HD and SD signals for 3G/HD/SD hybrid plants. It is identical to the XVP-3901 except that it does not have up/crossconversion capabilities. It features a dual 3G/HD/SD input selector and provides multiple outputs of the selected output format. The processor performs all the downconversion, color space and aspect ratio conversion needed to maintain the chosen output formatting on the outputs, irrespective of whether the input is 3G (Level A or B), HD 1080i, HD 720p or SD.
