Continuation. Read the beginning in the article NAB Show 2017: Monitors and Set-Top Boxes.

Solutions for Testing, Monitoring and Measuring Parameters

Nippon Control System presented a line of multifunction analyzers for UHDTV-DAB8000 mini.

The “6-in-one” solution is designed to monitor 4K/8K video, is housed in the half of the 3U case and consists of an analyzer/waveform monitor, signal generator, audio analyzer, signal converter (U-SDI<->8K 3G-SDI, RGB<->YCbCr), real-time protocol analyzer and focus assistant (simplifies to focus in difficult situations for 8K cameras).

KeySight Technologies presented digital its oscilloscope DS0Z11026 with a band of up to 100 MHz, and Tektronix is a prototype software solution for online monitoring.

Leader Instruments presented test equipment like the test signal generator LT4610 (3G/HD/SD), the multi-format video generator LT4600A and the module LT4448.

Antenna equipment

Focusing on the advanced industrial standards, Jampro Antennas presented its antenna JUXD, supporting Futurization Technology, which allows any polarization “reconfiguration” (if operators need it in the future) without having to change the antenna design. The solution is ideal for operators providing broadband access or multichannel broadcasting services in DVB-T2 and ATSC 3.0 standards, facilitating to select any polarization (horizontal, vertical, elliptical, circular).

AVL Technologies presented the model 1315, a segmented carbon 1.35-meter three-band antenna. The model is lightweight, consists of 12 carbon reflector fragments and can be installed just in 5 minutes. The polarization is selected manually. The stationary device withstands a wind speed of up to 45 mph.

Kathrein presented a line of UHF antennas with a power of 1 to 600 W (470-862 MHz), which are designed for a wind speed of up to 240 kph, and Dielectric presented an omnidirectional antenna system TFU-GTH-BB with up to 240 kW of power and elliptical polarization.


DJI presented its multi-copter Phantom 4 Advanced. The model is equipped with a 1˝ camera with a 20-megapixel CMOS sensor (4K60p/H.264, 4K30p/H.265). The control console has a 5.5˝ monitor (16:9) with a resolution of 1920×1080, a built-in memory of 16 GB and HDMI. The drone controllable range is up to 7 km. An accurate navigation is provided by GPS and GLONASS. The water and uneven surface landing disable is monitored.

At the Amimon’s stand, XDynamics presented its hi-end modular industrial drone D-02 with a carbon base (8-propeller version – octocopter) with an option of using different models of DSLR cameras, as well as the debut model XDynamics Evolve. D-02 is able to stay in flight for up to 20-30 minutes.

The number of “propellers” and equipment of D-02 depends on specific missions (ensuring speed, reliability, etc.). The reliability guarantees a smooth landing even in case of failure of one or more engines. Thanks to the Amimon’s firm-specific technology of wireless transmission with a minimum signal delay (under 10 ms), D-02 provides a stable and smooth FullHD video picture (1080p60).

The company JI Technology announced a prototype of the YI Erida copter (coming this summer). The model is made of carbon fiber, which significantly strengthens structural integrity (against the conventional steel) and reduces weight. The vehicle can stay aloft for up to 40 minutes and speeds up to 120 kph.

However, the drones explore not only air, but also water. So, PowerVision Group (PowerVision Robot) introduced its underwater robot PowerRay 4K with up to 20 minutes of operation time.

It should be noted that, despite the growing popularity of companies and individuals for multicopters (unmanned aerial vehicle, UAV) as a video shooting tool, the use of unmanned vehicles is not allowed in all places and countries. Even in view of the FAA’ authorization to use these devices for photo and video shooting in the United States, the use of drones is prohibited ,for example, on the Golden Gate Bridge in San Francisco, according to the warning near the bridge. A similar taboo is applicable to airports and other facilities. Therefore, before launching such a vehicle in the destination country, it is advisable to learn relevant application restrictions, in order not to face unpleasant situations that have occurred in Western Europe in recent months.

According to the Tractica VR market research, the revenues of the three main segments (tools for making VR content, head-mounted displays and other equipment) will grow rapidly in 2015-2021. So, if the total revenues of all three segments did not even reach USD 500 million in 2015, then this figure should approach the mark of USD 1 billion by the end of 2017, exceeding USD 2 billion in 2018, being more than USD 7 billion by 2020, and surpassing the mark of USD 9 billion in 2021.
