QAM Modulator (Digital TV Multiplexing & Scrambing QAM Modulator All-in-One NDS3343D)
1.1 Product Overview
Model 3343D 4-in-1 multiplexing, scrambling and QAM modulation all-in-one device is a newly developed high-integration, high-performance and cost-effective product. It supports multiple input configurations: 8×Tuner + 6×ASI, 4×Tuner + 6×ASI + 2×IP, 8×Tuner + 2×ASI + 2×IP, 4×Tuner + 2×ASI + 4×IP. After 4-channel multiplexing, 4-channel scrambling and 4-channel QAM modulation, it outputs 4 RF signals and also supports 4 IP outputs. Featuring high integration, excellent performance and low cost, it is ideal for new-generation CATV broadcasting systems.
