The Compact Portable Tx-II (CPTx-II) is a lightweight RF video transmitter that delivers HD/SD output at up to eight Watts in 2k DVB-T COFDM mode. The Nucomm CPTx-II, a compact, portable transmitter, is ideal for covering motorcycle and bicycle races, marathons, triathlons and other fast-paced, high-speed ENG/OB events using such smaller on-course vehicles as cars, motorcycles and even bicycles.

The CPTx-II supports video/audio/data/telemetry with selectable modulation bandwidths of 6, 7, and 8MHz. In addition to the small size, the units has very low latency and low power consumption, It weighs about 3 kg and comes with a variety of bespoke mounts, including special mounts for motorcycles. The maneuverability of a motorcycle fitted with video transmission capability offers significant advantages when covering road races, as the camera can follow the action and get onto roads that might be too narrow for a car to navigate safely among the athletes. To demonstrate the transmitter’s capabilities, IMT will have a motorcycle from its partner, TV Globo, outfitted with a CPTx-II on display at the show.

The video from the CPTx-II can be received on any MPEG-4-capable handheld receiver and receive site. As it uses advanced features of the H.264 codec, it is capable of a 30-percent bit-rate reduction and video quality improvement compared to other encoders. It is also capable of AES encryption, making it ideal for high-profile live sports broadcast applications.
