2×2 DVB-T2 car High Speed Diversity receiver for Thailand Russia

2×2 DVB-T2 car High-Speed Diversity receiver for Thailand Russia

Overview

A rugged, vehicle-grade 2×2 DVB-T2 receiver designed for reliable high-speed mobile reception and seamless video/audio output in challenging RF environments. Dual-antenna diversity with intelligent switching/combining ensures maximum signal stability and minimal dropouts at vehicular speeds. Built for fleet use, emergency vehicles, buses, armored vehicles and mobile broadcast/monitoring where continuous DVB-T2 reception is required across Thailand and Russia radio bands.

Features

• True 2×2 antenna diversity: two independent RF front ends with diversity combining and fast switching to reduce multipath and fading on the move.
• DVB-T2 compliant demodulation (backward compatible with DVB-T).
• High-speed optimized: firmware and AGC tuned for reception at vehicle speeds (including highway speeds and urban multipath).
• Wideband RF front end: supports common VHF/UHF DVB-T/T2 bands used in Thailand and Russia (configurable).
• Multiple outputs: HDMI, CVBS (RCA), and IP/TS over Ethernet (optional) for integration into modern systems.
• Audio outputs: embedded HDMI audio + analog audio out (RCA / 3.5mm).
• Telemetry & control: RS-232/RS-485 (or CAN) and web GUI for remote configuration and diagnostics.
• Robust power: 9–36V DC wide input for direct vehicle battery connection and transient protection.
• Ruggedized housing: metal enclosure, shock/vibration tolerant, operating temperature optimized for in-vehicle use.
• Low latency decode with accurate time stamping for synchronization and monitoring.
• Signal diagnostics: real-time SNR, BER, MER, constellation, channel scan and automatic re-lock.
• Firmware upgradable via Ethernet/USB; customizable profiles for region-specific channel maps.
• Optional features: GPS time/location metadata, dual-recording, recorder module (SD/USB), remote stream output to CMS/cloud.

Applications

• Public safety & emergency services: live broadcast/monitoring in police, ambulance, fire vehicles.
• Mobile broadcast & ENG (electronic news gathering): in-vehicle monitoring of over-the-air channels.
• Fleet & transportation: passenger info systems in buses/trains; regional channel delivery.
• Military & security patrols: resilient reception in severe multipath and fast-moving platforms.
• Broadcast monitoring & compliance: field monitoring for regulators or operators.
• Tourism & hospitality transport: coach/carriage entertainment distribution combining DVB-T2 with local AV.
• Backup & redundancy: vehicle-based backup receiver to complement satellite or IP feeds.

Country/regional notes

FAQ

Q: What does 2×2 diversity mean?
A: Two independent antenna inputs with diversity combining/switching to reduce dropouts and improve reception in mobile/multipath environments.
Q: Will it work at highway speed?
A: Yes — receiver AGC and demod parameters are optimized for high-speed vehicle operation; performance depends on antenna placement and RF environment.
Q: Can it stream over the vehicle network?
A: Yes — the unit supports TS over UDP/TCP and can provide RTSP/HTTP streams for remote monitoring.
Q: Can you preload channel maps for Thailand and Russia?
A: Yes — we can supply region presets and channel lists for easier deployment.
