SDX-1080DTA Backpack Duplex Voice HD Video System

Overview

The SDX-1080DTA Backpack Duplex Voice HD Video System is a military-grade, ultra-low-latency wireless video transmission platform designed for broadcasters, public safety teams, and defense forces who require real-time HD video with simultaneous two-way voice communication. Housed in a standard military backpack frame with integrated SONY V-lock battery mount, the system achieves a remarkable 60 ms end-to-end latency -- five times faster than conventional COFDM systems -- while maintaining robust NLOS performance through urban, forested, and mountainous terrain.

The SDX-1080DTA combines COFDM modulation with full-duplex voice intercom, bidirectional RS232/RS485 data channels, and military-grade 256-bit AES encryption. Its 1-8 MHz adaptive bandwidth and 2W transmit power provide a practical NLOS range of 1-3 km and line-of-sight reach of 2-5 km, making it the go-to solution for live broadcast relay, tactical surveillance, and emergency command operations.

Key Features

• 60 ms ultra-low system latency for real-time interactive command and live production
• Full-duplex digital voice intercom enabling simultaneous talk-and-transmit during operations
• Military-grade 256-bit AES dynamic encryption for secure tactical links
• SDI + HDMI dual video inputs with SDI loop-out for local monitoring
• Adjustable 1-8 MHz channel bandwidth via LCD panel for spectrum optimization
• 2W COFDM transmit power with 1-3 km NLOS and 2-5 km line-of-sight range
• Standard military backpack frame with SONY V-lock battery and DC short-circuit protection
• Bidirectional RS232/RS485 data at up to 115200 bps for telemetry and peripheral control

Technical Highlights

The SDX-1080DTA's standout achievement is its 60 ms latency -- achieved through optimized H.264 encoding pipelines and COFDM modulation parameters that minimize processing delay without sacrificing multipath resilience. The system supports exceptionally wide channel bandwidth selection (1 through 8 MHz in 1 MHz steps), giving operators fine-grained control over the trade-off between range, throughput, and interference immunity.

The receiver is built into a 1U 19-inch rack-mount chassis with dual-antenna spatial diversity, built-in cavity filtering, and LCD-based signal strength indication. The SDI loop-out on the transmitter allows field operators to verify the transmitted feed locally without an additional monitor.

Applications

The SDX-1080DTA is deployed by broadcast television stations for live news gathering, sports relay, and aerial live production where zero-latency interaction between cameraperson and director is essential. In the public safety and defense sectors, it supports tactical team-to-command-vehicle relays, manpack-to-studio feeds, and emergency on-site video backhaul.

The overall transmission architecture typically runs from the backpack operator to a communication vehicle within 1 km, where the signal is relayed onward to a command center over IP or microwave backhaul. The system's fast 60 ms round-trip enables live two-way interviews and real-time remote direction without perceptible delay.

Why Choose This System

The SDX-1080DTA is the only backpack video system that delivers true 60 ms latency alongside full-duplex voice, AES-256 encryption, and military-grade ruggedization in a single integrated package. For broadcasters and tactical teams alike, this combination of speed, security, and mobility redefines what a portable wireless video link can achieve in the field.
