Let's talk about training
playing from 64 to 192 audio
channels. This allowed the companies
to train their own specialists and have
a " bench " ready to join the work at any
time.
Thus the " Academy " evolved from a
system for training personnel in sports
broadcasts, to a convenient simulator
for training diverse professionals.
The " Academy " is also actively
used to coach replay operators
and video referees, including Video
Assistant
Referees
in
football
and
Video Goal judges in ice hockey. Like
production directors, referees and
replay operators work in a high-stress
environment, but the price of their
mistake is significantly higher, since
it can affect the outcome of the entire
match, position of the team in the
standings and their own career.
Given the fact that the regulations
of the competitions indicate all the
basic issues in which a video referee
is involved in resolving a controversial
situation, slomo.tv specialists in
agreement with the sports leagues
prepared a large library of training
materials for video referees (VARs)
and replay operators.

high-qualified referees and replay
operators, but also a great tool for
practicing and training during long
breaks, for example, between seasons.
An
interesting
positive
effect
of
Video
that
referees
require
study the
their
attention,
issues
and
learn how to handle them. The
replay operators train to control the
system in order to quickly show the
referees the camera angles of the
moments they are interested in. At
first, the training is carried out on
sets of specially selected moments,
each of which represents a certain
type of issue. At this stage, referees
and replay operators learn all types
of standard controversial situations.
At
the same time,
communication
and interaction between the referee
(VAR) and the operator is practiced.
This stage is followed by working with
random events and situations where
controversial moments go one after
another. It helps to improve the stress
tolerance and train to quickly make the
right decisions, the learned material is
consolidated.
The operator's actions are brought
to automaticity by learning to prepare
the necessary video material in the
background without a voice command
- based on an understanding of the
game and the aspects to which the
video referee draws attention. The
final training sessions are carried out
using the full match records. It is very
important that at each stage there is
a review and correction of the actions
of each trainee. The " Academy " is not
only a quick and easy way to train
the " Academy " is the possibility to
organize a " quality loop " . The multichannel
videos of new and difficult
refereeing errors that occurred during
a certain number of matches in the
regular season can be sent to the
training center and uploaded to the
" Academy " . Experts and instructors
analyze these errors, develop and
work out the order of actions in such
situations, and then conduct shortterm
training for practicing referees
on these
materials.
It can help
continuous improvement
in
of the
referees qualification and decrease the
number of errors of the same type. The
same video materials can be added to
the " Academy " library and be included
in the training program for the new
referees and replay operators.
Summarizing all of the above, the
" Academy " is the technology for
rapid
intensive
training
of
various
specialists, video referees, replay
operators and is a convenient tool for
keeping their skills at a high level.
