1. Product Overview
1.1 Description
DBS has built upon the outstanding features of the award-winning DTC NanoHD TX to create the
ultimate PoV miniature broadcast transmitter.
The DBS Nano PRO Transmitter is an ultra-miniature COFDM digital video transmitter, designed
specifically for Point-of-View (PoV) and body-worn applications.
With proven DTC COFDM and H.264 encoder technology at its core, exceptionally small size, and
ultra-low power consumption (typically 7W), the DBS Nano PRO TX enables production teams to offer
viewers stunning high-definition images from the heart of the action, in situations never previously
possible due to equipment size and battery run-time constraints.
The small size and ultra-low power consumption make the DBS Nano PRO TX ideal for UAV
Octocopter installations, enabling true long range HD broadcasting from these increasingly popular
devices for the first time. Optional lightweight, low power consumption amplifiers are also available for
even greater range capability.
The transmitter employs ultra-low latency High Profile H.264 (MPEG-4 AVC) encoding for excellent
image quality retention over the wireless link and supports SDI and HD-SDI video input formats up to
1080p50/59.
The DBS Nano PRO TX is supplied in a slimline, fan-cooled, aluminium lightweight case and features
industry standard connectors for RF (SMA), video (BNC), power/data (Hirose), audio (Hirose) and
control (mini-USB). An integrated joystick control panel and OLED display are provided for control and
monitoring of all parameters.
1.2 Basic Specifications
