With the ongoing need to increase bitrate efficiency, today’s operators require more robust modulators that can deliver the maximum bits per Hz. Sencore’s range of satellite modulators offer higher bitrates for DBS, contribution, and SNG operations with such features as efficient 8PSK, 16-QAM and QPSK modulation, as well as variable coding and modulation (VCM) which enables each transport stream in the single RF carrier to have its own modulation parameters. This multistream capability reduces overall equipment requirements and increases the efficiency of transponder use while guaranteeing the integrity of the content.
