Hollyland Cosmo C2 looks to solve wireless video problems

Wireless video transmission remains a complicated process with more than one challenge along the way, something that Hollyland’s new Cosmo C2 is designed to help with.

The new Hollyland Cosmo C2 has been created to nix many of the problems that can still bedevil wireless productions. For a start it offers an extended line-of-sight wireless transmission range of 3000 ft (1000 meters) and a back-to-back transmission distance of over 980 ft (300 meters), effectively preventing insufficient transmission distances and avoiding screen glitches and stuttering. It also boasts a latency as low as 33ms, ensuring seamless synchronization for both displays and streams on-site.

One of the keys to its success in achieving all this is the 2TX (transmitter) and 1RX (receiver) configuration it utilises. This addresses issues typical of traditional 1TX and 1RX setups, such as excessive cabling, spatial constraints, and synch delays between camera feeds. 

It uses the company’s proprietary HEVO 2.0 technology to address common issues in live streaming, such as screen glitches or stuttering due to environmental interference, and can automatically detect surrounding frequency interference and seamlessly switch to a clean channel, ensuring uninterrupted transmission. 

It also usefully converts low frame rate inputs to 60p using a new frame rate compensation algorithm to ensure a smooth picture, and will retain the last frame upon unexpected signal loss. This helps to prevent that awkward moment where all the viewers sees is the manufacturer logos if the signal drops during commercial live streaming.

Interestingly enough it is also a genuinely plug-and-play product and features NDI, UVC, and RTMP outputs for a wide range of connectivity options. By integrating NDI support directly into its receiver, it enables seamless local area network video streaming without additional converters. It also facilitates direct UVC streaming via its Type-C port with a USB-C to USB-C cable, bypassing the need for a capture card. And its RTMP capability allows direct cloud streaming, eliminating reliance on external devices for real-time transmissions.

The system includes comprehensive input and output ports, offering HDMI Input, SDI Input, and SDI Loopout on the transmitter, alongside multiple HDMI and SDI outputs on the receiver. And that multiple options theme continues with the transmitter supporting DC power and NP-F batteries, while the receiver accommodates DC power and V-Mount batteries, ensuring uninterrupted operation across different shooting scenarios.
