Domo Broadcast Systems’ PicoTX COFDM transmitter takes sports coverage to new heights

Domo Broadcast Systems (DBS) has released the DBS PicoTX, an ultra-miniature COFDM digital video transmitter designed for the unique needs of those using body-worn and miniature drone applications.

The PicoTX offers COFDM transmission at 50mW and progressive format video encoding in HEVC or legacy H.264, all in an exceptionally small package. It has a volume of only 25 cubic-cm and consumes less than 4.5W when transmitting 1080p50/59 with HDR at full power.

“We wanted to provide camera operators working remotely with a solution that would transmit at high quality using COFDM but not be an intrusive extra bit of kit,” said Stuart Brown, broadcast systems engineer with Domo Broadcast Systems.

“At 25cm3, the PicoTX is exceptionally small. So, it can easily be body-worn mounted. Not only that, but its small size also means it can be fitted to the smallest FPV drones. This allows production teams to offer stunning, high-definition images with HDR that were not previously possible.”

The features of the PicoTX will benefit a host of applications.

“Having a PicoTX on board a collection of drones means broadcasters can more effectively and efficiently cover a major event over a wide area — such as large-scale festivals or long-distance races — or over hard-to-reach areas — such as mountain venues, desserts, or for water sports,” added Brown. “It’s a huge win. We know from our experience building bespoke solutions for major sports broadcasters that this will take sports coverage to new heights.”

The PicoTXcan be supplied with optional HDMI interfaces and a dedicated, lightweight, body-worn camera. Camera control is achieved through a built-in UHF return link.

“The engineers at Domo Broadcast Systems are serious innovators,” said Mike Budge, broadcast unit director for Domo Broadcast Systems. “We are counted on to be continuously providing solutions for what many consider impossible. Our close ties with the sports industry and the fact that our engineers have worked in broadcasting means we fully understand and can anticipate their needs. We delight in not only problem solving, but continuing to help advance the industry.”
