About DVB-T2 ASI modulator and demodulator products
DVB-T2 Modulation Board (with ASI Input) and Demodulation Board (with ASI Output): Functions and Features
1. DVB-T2 Modulation Board (ASI Input)
Fonction
- Converts ASI input signals (typically MPEG-TS streams) into DVB-T2-compliant RF signals for broadcast transmission via antennas or cable networks.
- Applies advanced DVB-T2 encoding and modulation techniques (par ex., LDPC/BCH error correction, QPSK/16-QAM/256-QAM modulation) to enhance spectrum efficiency and robustness.
Principales caractéristiques
- ASI Interface: Directly connects to ASI-based devices like encoders or multiplexers.
- Flexible Configuration: Supports adjustable parameters (par ex., Taille FFT, intervalle de garde, pilot patterns) to optimize performance for varying environments.
- High Efficiency: Utilizes DVB-T2 advancements (par ex., MISO, rotated constellations) to maximize data capacity and coverage.
- Faible latence: Designed for real-time applications such as live broadcasting.
Applications
- TV broadcast transmitters, IPTV head ends, satellite uplink stations.
2. DVB-T2 Demodulation Board (ASI Output)
Fonction
- Receives and demodulates DVB-T2 RF signals, restoring them to ASI-formatted MPEG-TS streams.
- Corrects transmission errors using DVB-T2’s LDPC+BCH error-correction coding.
Principales caractéristiques
- Haute sensibilité: Stable reception in low signal-to-noise (RSB) environnements, ideal for weak signal areas.
- Robust Against Interference: Mitigates multipath effects via OFDM and dynamic channel equalization.
- ASI Output: Delivers standard ASI streams to downstream devices (par ex., decoders, recording systems).
- Real-Time Monitoring: Provides diagnostics (par ex., force du signal, bit error rate) for network management.
Applications
- TV receiver stations, cable head ends, mobile reception systems (e.g.,车载TV).
3. Common Features
- DVB-T2 Compliance: Ensures global interoperability with standardized equipment.
- High Reliability: Industrial-grade design for 24/7 opération.
- Network Support: Compatible with Single Frequency Networks (SFN) and Multi-Frequency Networks (MFN).
4. Cas d'utilisation
- Radiodiffusion: Terrestrial digital TV, mobile TV (par ex., public transport systems).
- Professional Systems: Emergency communications, live event streaming, distance learning.
- Data Services: IP data broadcasting (par ex., OTA software updates, ad insertion).
Résumé
- Modulation Board: Acts as the émetteur, converting ASI streams into robust RF signals for distribution.
- Demodulation Board: Acts as the récepteur, recovering ASI streams from RF signals even in challenging conditions.
- Ensemble, they form a complete DVB-T2 transmission chain, enabling high-capacity, high-reliability digital broadcasting.
Advanced DVB-T2 decoder designed for seamless ASI signal integration.
Robust DVB-T2 receiver ensuring flawless ASI output transmission.

I have been using the DVB-T2 ASI modulator and demodulator modules for several broadcasting projects, and they are outstanding. The modulator reliably converts ASI MPEG-TS streams into DVB-T2 RF signals with minimal latency, while the demodulator accurately restores the streams to ASI output, even in low SNR environments. Configuration is flexible, with adjustable FFT, guard intervals, and modulation schemes, allowing optimization for different broadcast scenarios. The modules are compact, robuste, and highly reliable, making them ideal for professional TV broadcasting, IPTV head ends, mobile reception, and other mission-critical applications.
