Title
• APPARATUS AND METHOD FOR PLAyING VIDEO
BASED ON REAL-TIME DATA
■ Problems of conventional art
• A conventional video playing apparatus is being widely
used for post-processing of flight data or in simulation
systems, and simulation environment includes a ground
control system, a flight control computer, a computer
to simulate a mounted system, a motion modeling
computer, a 3D video computer and a screen.
• While these conventional video playing apparatuses
transmit an orientation and position of the aircraft,
and actuator information to the 3D video computer
to display configuration and position information
of aircraft, the data used for displaying is limited
to simulation data, and is mainly used during pilot
training in virtual environment, and thus a range of the
use is limited.

Receiving position information
of aircraft to display received
results in real time
Distinctiveness
• Flight data is received in real time to display a 3-dimensional video of information of an aircraft
such as a position, speed and attitude, so that operational stability using geographic information
and 3D aircraft information, and a situation recognition rate can be increased to be applicable to
precision relative navigation using 3D information extended from 2D information.
Technical effects
• The attitude and position of the aircraft can be visually identified using real-time data transmitted
through a communication system during actual flight.
The "smart unmanned device" development project has been promoted, and hardware and
software necessary for ground control that controls a smart unmanned device have been
developed since 2002. There has been an example of technical transfer of a ground control
system for an unmanned aerial vehicle based on the obtained technology.
• Conventionally, an internal pilot can know an attitude and position of the aircraft only as
numbered information, however, the pilot can visually identify the attitude and the position of the
aircraft using the apparatus for playing a video based on real-time data, and thus it is helpful for
the pilot when operating the aircraft.
• When the apparatus for playing a video based on real-time data is used in flight tests, flight
information analysts can identify the attitude and the position of the aircraft at a glance, and thus,
can determine a reaction of the aircraft with respect to an operational command at a glance and in
a very short time.

Market and future prospects
Apparatus and
Method for
Playing Video in
Real Time
• The ground control system is an essential element for
operating an unmanned aerial vehicle, and about 5 and 6%
of the expenditures for development of the unmanned aerial
vehicle out of the development of the smart unmanned aerial
vehicle is injected into the ground control system.
• The unmanned aerial vehicle market is expected to grow at
an average annual rate of 8% by 2020 to be developed to the
market size reaching 11.4 billion USD. European countries,
and Asian countries such as China and Singapore have
actively participated in development of the unmanned aerial
vehicle, and in particular, China has proceeded with its own
development of the high altitude long endurance unmanned
aerial vehicle and unmanned combat air vehicle.

Global Unmanned Aerial Vehicle Market Size
59
• Companies that manufacture system/aerial vehicle design, aerial vehicle manufacturing, ground
control system, ATC, supervisory equipment, radar, flight support system are the main market.
• As the intelligence and autonomy of the unmanned aerial vehicle are getting higher, one pilot
can operate a plurality of unmanned aerial vehicles. In addition, for this purpose, research into
development of Man-Machine Interface has been actively progressing.
