Atsc Digital Up Converter

Our company is involved in manufacturing and supplying a wide range of ATSC Digital Up Converter to our patrons from Kaohsiung, Kaohsiung Shih, Taiwan. The DUC-135 & DDC-135 digital up-converter and down-converter have been carefully designed to integrate digital off-air channels into any private cable system. The DDC-135 digital down-converter converts a digital off-air or CATV input to a 44 MHz IF signal. The DUC-135 digital up-converter accepts the 44 MHz IF signal and converts it to an 8VSB or QAM output signal on a CATV channel from 2~135 or an off-air channel from 2~69. All sub-carrier channels (x.1, x.2, x.3 etc.) are included in the conversion. Each unit occupies a single space in a 12 unit rack chassis allowing up to 6 channels to be integrated in a single chassis occupying 2 rack spaces (3.5a ). The input modulation format (ATSC or QAM) is maintained from the down-converter to the up-converter (ex. QAM to QAM or ATSC to ATSC). These units do not convert digital off-air signals (ATSC) to QAM modulated signals.
