Encoder MPG4 8x1 HD



Part Number : NTX-INT2108-I

INT2108-I 8 IP Mux-Scrambling and modulation module is the latest generation Mus-scrambling-modulating all-in-one device. The modular design of this device makes each of its daughter cards stand-alone when operating. Each daughter card can receive the UDP format TS trough GE port, it can also support up to 256 different IP address or port No. It's like the all-in-one device combined with 8 multiplexers (256 channels inputs), 8 scramblers and 8 QAM (DVB-C) modulators, wich can output adjacent channel RF carrier (48M~960M) trough the two RF output interfaces. Additionally, chassi supports up to 3 modules' INT2108-I (256 channels mux-scrambling-modulation) while the 4U chassis supports up to 12 modules (1024 channels mux-scrambling-modulation). This INT2108-I 8 IP Mux-Scrambling and modulation module has excellent integrated level, powerful performace and low cost, which is especially adequate for the new generation CATV system.
