DJI, the renowned Chinese technology company, has announced a new wireless video transmission system, SDR Transmission, targeting smaller film crews. This lightweight and affordable system boasts impressive capabilities, transmitting a 1080P 60fps video signal up to 3km (1.8 miles) with a low latency of 35ms.
Introducing SDR Technology:
The heart of SDR Transmission lies in DJI's proprietary SDR (Software-Defined Radio) technology. This innovative approach to wireless communication, developed over a decade, promises superior range and reliability compared to Wi-Fi-based systems, all while maintaining a competitive price point. DJI claims SDR offers higher resolution and bitrate, stronger signal penetration through obstacles, and enhanced resistance to interference. Unlike Wi-Fi, the SDR system can handle an unlimited number of receiver devices in broadcast mode.
Key Features and Specifications:
- Video Transmission: SDR Transmission delivers FullHD 1080P 60fps video with a bitrate of 20Mbps, reaching a maximum distance of 3km (1.8 miles) in ideal conditions. The system automatically adjusts across 2.4 GHz, 5.8 GHz, and DFS frequency bands to find the optimal channel, ensuring stable performance even in areas with interference. - Connectivity: The transmitter accepts both SDI and HDMI inputs, allowing for a versatile setup. It can simultaneously output three SDR signals and two Wi-Fi signals. The receiver offers SDI and HDMI video outputs for monitor connectivity and USB-C or Wi-Fi for wired/wireless connection to smartphones and tablets. - Remote Control and Metadata Transfer: SDR Transmission goes beyond simple video transmission. It supports remote camera control, enabling users to adjust aperture, shutter speed, and ISO, trigger photo capture and video recording, and even access PTP control for compatible cameras. Additionally, the system allows for metadata transfer, providing valuable shooting information directly to the crew. - Powering Options: SDR Transmission units can be powered through USB-C PD, Sony NP-F-style battery plates, or directly by compatible DJI RS series gimbals when mounted. - Physical Design: The compact design of the transmitter and receiver units, weighing only 145g (5.1oz) each, makes for easy transport. The antennas fold down for further compactness.
Pricing and Availability:
The DJI SDR Transmission is now available for purchase both individually and as a TX-RX kit. Prices are as follows:
DJI's SDR Transmission offers a compelling solution for smaller film crews seeking a reliable, affordable, and feature-rich wireless video system. Its impressive range, low latency, and ability to handle multiple receivers make it an ideal choice for a variety of productions. The combination of advanced SDR technology, remote control capabilities, and metadata transfer ensures a seamless workflow and professional-grade results.
