BOXX TV ATOM Boxx TV has a number of wireless products on offer including the Atom dual channel directors monitor, the Meridian portable system, the Atom Lite system (pictured) and this one, simply the Atom. The Boxx Atom provides a zero delay microwave transmission solution for a host of video assist requirements in a small lightweight form factor. Operating within the 5GHz licence exempt spectrum, the features have been designed for today’s fast-moving productions. The Atom system has been optimised to work out of the box with minimal configuration. Performance can be monitored and adjusted in real-time at the touch of a button without manual pairing requirements or the need to connect to a PC to set attributes prior to operation. Atom operates well in a multi-camera environment by making the most efficient use of the available spectrum. The system ensures reliable coverage thereby reducing the possibility of interference when using multiple transmitters. The compact lightweight transmitter offers SDI, HD-SDI and HDMI inputs; perfect for a variety of uses including Steadicam, portable field monitoring and UAV video links. It is this small and lightweight form factor that is a real attraction for crews and directors. Also the on-board manual channel selector saves you time when you’re shooting. You also can’t overestimate the value of having a system that doesn’t need pairing from coming out of the box. Also unlike other similar systems there are no limits on the number of receivers you can connect to and there are no range limitations from this technology. That makes the Boxx TV Atom system perfect for multi-camera set-ups when start-up and fast initial camera recording is vital.
DEJERO ENGO Dejero’s EnGo mobile transmitter combines Dejero’s industry-leading auto- transport and adaptive bit rate encoding technology (which optimises picture quality when there’s limited available bandwidth) with HEVC. This means that field broadcasters can take advantage of the enhanced efficiency of HEVC compression to provide higher quality video at even lower bit rates. EnGo is probably the most versatile mobile transmitters out there – being mountable on a camera or vehicle, or carried in a backpack. Its picture quality, ease of use, and reliability are quite remarkable. This is down to Dejero’s patented network blending technology which enables the EnGo to efficiently transport high- quality video over multiple IP networks, including cellular, Wi-Fi, Ethernet and satellite; thus, delivering exceptional picture quality with extremely low latency. International travel is also made easier with global roaming options and the EnGo transmitter’s convenient user-changeable SIMmodule. It enables field operators to quickly and easily switch between different sets of SIMs for optimal performance in the local cellular network environment. EnGo also transfers video to Dejero receivers while live or recording, performs rapid uploading of recorded clips to get footage back to the station as quickly as possible, and enables field operators to rename the recorded clips to simplify file management. The EnGo Vehicle Mount Kit option allows the EnGo to be used like a rack- mounted encoder/transmitter in a cellular, satellite or hybrid IP transmission vehicle. It can also be quickly disconnected from the cradle and placed in a backpack or mounted directly on a camera to give crews maximum mobility at the scene of breaking news and at live events.
IDX CW-F25
Designed for on-air video contribution, the new CW-F25 wireless HD-SDI transmission system from IDX offers great image quality transmitting H.264 high profile video at up to 25Mbps. Adaptive variable bit rate prevents sudden disconnection and range is enhanced by the use of beam forming technology operating over four 4MIMO channels. Supported across the link are return video, intercom, tally, RS422 remote and Ethernet I/O giving the remote camera operator the features of a wired link in a licence-free product. The CW-F25 does restrict its transmission of video and audio to 2000m (6561ft) maximum range as long as you are experiencing free-line-of-sight. Most of these systems are successful because of the importance of the video signal. The IDX CM-F25 uses fully professional 3G-SDI /HD SDI links over H.264 compression at up to 25Mbps transmission rate. The unit also uses Adaptive Variable Bit Rate Control to make sure and provide a robust link at the highest sustainable video quality which is now an expected feature of wireless systems. A great feature from this IDX unit is the use of Beamforming technology which makes a directional beam between the transmitter and receiver limiting interference from other 5GHz users and providing a strong stable link. DFS (Dynamic Frequency Selection) provides auto selection from nine channels in total. Also Bidirectional Signal and Data Transmission support return video, intercom, tally and RS422 control data Wireless LAN Bridge Ethernet I/O at both Tx and Rx make a wireless bridge to support an IP camera feed, remote controller or other data link. There are also four channels of embedded PCM audio and the unit is fully certified for use in Europe.
