DJI develops a video transmitter with advanced SDR technology

The new DJI SDR Transmission, with advanced Software Defined Radio (SDR) technology, offers film and television producers a reliable, flexible and efficient solution for on-set video transmission and monitoring.

Designed for small and medium sized film crews, this solution offers greater stability, strong interference resistance y robust penetration capabilities. For situations requiring temporary monitoring, you can allow Wi-Fi streams simultaneously, to give filmmakers the flexibility they need on set.

Paul Pan, product line manager at DJI, says that “from the beginning, we intended our DJI PRO line to be a complete and reliable ecosystem of drones, cameras and creative tools, both for professionals in the film industry and for content creators who want to tell stories,”

"Listening closely to user feedback, we continue to expand our offering of creative camera technologies, with special attention to what they need. Our new DJI SDR Transmission offers image quality on the same level as film and television, but at a price more accessible to more future filmmakers," he adds.

High quality and maximum stability

With SDR technology, DJI SDR Transmission ensures stable video transmission even in complex recording environments. The filmmakers will see on the monitors live signals in 1080p/60 fps with a bit rate of up to Mb/s and a minimum latency of 35 milliseconds. The videos can be transmit over a distance of up to 3 kilometers. Combined with next-level penetration capabilities, live video signals remain stable, even in complex recording environments. When there is interference on a channel, it automatically jumps to the 2.4 GHz, 5.8 GHz and DFS frequency bands to find the optimal channel.

DJI SDR Transmission makes collaboration more efficient for the entire creative team on set. Can generate three SDR signals and two Wi-Fi signals simultaneously. In Broadcast mode, you can connect to an unlimited number of receivers, making a high-quality monitoring experience possible for multiple collaborators. The receiver can connect to monitors via SDI/HDMI and to smartphones and tablets via USB-C or Wi-Fi. The Wi-Fi option allows for an economical dual-channel monitoring experience, without the need for another receiver.

Remote camera control

When used with DJI RS series stabilizers, the DJI SDR Transmission allows you to use Force Mobile and the virtual joystick and stabilizer recentering functions. When combined with a camera, it allows PTP control, display and adjust aperture, shutter, ISO and even activate the camera's photo and video recording functions through the application. It also allows CEC control of Sony cameras, so you can use the mirrored control mode.

DJI SDR Transmission can transmit metadata, making it easy to collaborate throughout the recording. When DJI SDR Transmission is connected to the DJI Ronin app In Broadcast mode, users can easily change camera ratings in the app. Leading film cameras on the market, such as ARRI and RED, can be adapted via SDI to give directors, digital imaging technicians and cinematographers access to detailed footage information in real time.

Finally, note that DJI SDR Transmission uses a PD protocol loader standard with power input USB-C. It can also be powered directly by DJI RS 4 Pro, DJI RS 4 or DJI RS 3 Pro when installed and used together, eliminating the need for a separate battery. By themselves, both the transmitter and receiver are compatible with industry-standard NP-F batteries.

With a lightweight design, each transmitter or receiver alone weighs 145 grams. Additionally, the antenna folds down for easy carrying and storage.
