CVW Aurora Wireless 4K Video Transmission System Explained

by Jürgen MoorsApril 24^th, 2023

CVW has introduced the Aurora, a wireless 4K video transmission system for broadcasters and live TV productions. It transfers a 4K HDR video with 10bit and 4:2:2 over a distance of 500 meters (1640ft), with a latency of 50 msec, including a tally signal, time code, and an intercom signal. At this year’s NAB, we had the chance to talk to Richard Yuan from CVW, and he showed us the features of this advanced system. The Aurora System is available for pre-order for $12,500. Let’s have a closer look.

When it comes to wireless video transmission systems, there is a big range of products on the market. For example, you can get the FEELWORLD W1000H HDMI system for only $470, or you could get yourself a Teradek Ranger MK II 5000 12G-SDI/HDMI system for $16,490. There is a big difference between these two systems, which is why the interview with CVW’s Richard Yuan is so interesting.

Aurora System

Established in 2010, CVW is a Chinese manufacturer mainly focusing on reliable wireless video transmission systems for the high-end market of the TV and film industry.

The Aurora is an IP-based system that is designed for live TV broadcast productions where you need to transmit a wireless video signal in the best possible quality. The Aurora system can transmit up to 4K HDR with 60p, with 10bit color depth, and 4:2:2 chroma sub-sampling. They are using an H.265 HEVC codec and could achieve a latency of less than 50 milliseconds. This is unique, and so far, we haven’t seen this kind of quality on a wireless video transmitter before.

Apart from the video signal, the Aurora system also has a tally light indicator on both units, a time code signal, additional camera control signals for PTZ cameras, and the intercom signal so you can communicate directly with the operator.

The maximum operating distance is between 300 and 500 meters (990ft to 1640ft), depending on the surroundings and unobstructed view. The Aurora system can find the best available network automatically by scanning all the possible channels and establishing the most reliable connection. As an IP-based device, the Aurora converts your signal inside the transmitter and you can send proxies automatically to the cloud. It also supports all the internet RTSP protocols, so you can transmit directly from the device to the cloud.
