DVB-T/T2 8-ASI Scrambler

DVB-T/T2 8-ASI Scrambler is a fully integrated professional broadcasting solution combining an 8-input ASI remultiplexer, DVB-T/T2 scrambler and high-performance RF modulator in a single 1U rackmount chassis. Designed for digital CATV and terrestrial RF networks, it enables operators to form complete DVB-T/T2 transport streams from eight independent ASI sources, generate one or two RF carriers within the 36–850 MHz range and broadcast SD/HD content using H.264 or H.265 encoding.

With subcarrier spacing up to 48 MHz and spectrum allocation flexibility, the DVB-T/T2 8-ASI Scrambler is suitable for regional broadcasters, IPTV-over-RF systems and multi-channel head-end stations. It supports CI-enabled DVB-T/T2 STBs, with over 90% receiver compatibility, providing secure and stable transmission of SD and HD channels. The system also includes an IP output (UDP/RTP), enabling hybrid RF and IP distribution, TS monitoring and post-processing workflows.

✅ Optimized for DVB-T/T2 head-end broadcasting

The DVB-T/T2 8-ASI Scrambler supports advanced COFDM modulation across multiple DVB-T and DVB-T2 modes, including 1k–16k FFT sizes, wide bandwidth options (1.7–8 MHz) and high-quality constellations up to 256QAM. Its dual-carrier architecture allows simultaneous broadcasting of two multiplexes, making it ideal for digital terrestrial networks.

✅ Integrated remultiplexer, scrambler and RF modulator

Combining ASI remultiplexing, MPEG TS restructuring, scrambling and DVB-T/T2 RF output in one device simplifies head-end design and minimizes system footprint. The device generates up to 92 PIDs from eight transport streams, supporting full TS shaping, PSI/SI editing, PCR correction and stuffing control.

🛠️ The DVB-T/T2 8-ASI Scrambler provides intuitive LAN-based configuration via Ethernet, enabling operators to manage DVB-T/T2 modes, RF frequency, output power, modulation types, bandwidth, PID mapping and PSI/SI/EPG structures. The IP port supports RTP/UDP streaming for TS monitoring, remote routing and integration into IPTV platforms.

🛒 This DVB-T/T2 8-ASI Scrambler is ideal for broadcasters, CATV operators, terrestrial network providers, IPTV-over-RF systems, regional retransmitters and head-end stations. It delivers reliable RF output, flexible modulation, CI-compatible scrambling and multi-interface connectivity for professional digital TV delivery.
