ESports Broadcasting Server What Should It Be Like?
Igor Vitiorets, CTO, Slomo TV, considers the requirements for an
eSports replay system suitable for broadcast applications...

T

he debate about whether eSports
is a real sport or a kind of show has
not subsided to this day. There is no
definite answer to this difficult question.
In modern public discourse there are
only those sports that have become
shows. It is impossible to have large
advertising budgets without a show
and related television broadcasting.
And professional sport is impossible
without advertising budgets. "Big"
sport does everything to make the
show more exciting. Everything is done
so that the viewer does not "switch the
channel" - from the organisation of
competitions and up to the change of
the rules and regulations of the sport.
There tendency for "big sport" is that it
is becoming more and more an exciting
show.
By its definition that "sport includes
all forms of competitive physical
activity or games" it is possible to
categorise eSports as sports.
Classical vs eSports
As was said before, no sport can
become successful without broadcasts
and entertainment. Broadcasts must
be so fascinating, that it is impossible
for a viewer to break away. The
principle is the same as traditional
sport and it seems that success can
be achieved by using the standard
methods of sports broadcasts.
But here we come across the
fact that broadcasting of eSports

competitions itself differs from work in
classical sports.
In classical team sports, the focus
is on the ball or the puck and the
struggle around them.
The most popular eSports (CounterStrike: Global Offensive; Call of Duty;
League of Legends; Dota 2) are multiplayer video game competitions in
which the actions of each player on
the team are constantly significant.
This greatly increases the complexity
of showing such competitions. The
broadcast director should not only
be professional, but also have a good
understanding of the "game" itself,
know the specifics of the teams and
individual players. Only then the
action will show spectacularly and
adequately.
As a rule, a match between teams
consists of a large number of rounds,
going sequentially with a short
break. The director and producer
of broadcast have a very short gap
between the rounds in order to show
the best moments of the round with
commentaries and explanations. Due
to this specificity, the role of replays in
the broadcast of eSport tournaments
is significantly more important than in
classical sports.
Replay Requirements
All this creates a whole set of
requirements for the process of
replays: for the organisation, for

equipment and for the team of replay
operators.
Since eSport depends on computers,
the servers must support 3G signals
(1920x1080p60). Usually such signals
are produced by using HDMI-SDI
converters. Although you can still
find solutions when the input signal
1920x1080p60 is downscaled to
1280x720p60 for replay servers that
do not support 3G, and after replays
the signal is up-scaled. This solution by
no means is optimal, not only because
there is significant signal quality
degradation, but also because such
servers (with maximum of 4 recording
channels) require a large number of
operators.
A very important parameter for a
replay server in cyber tournaments
is its channel performance - i.e.
the number of recording, search
and playback channels that one
server can provide. Classic replay
servers mimic the architecture from
traditional replay servers and define
server capacity by the total number of
channels that can be used for either
Record or PLAY or Search. Therefore,
a 6-channel server can work in 4REC
+ 2PLAY / PLAY + SEARCH mode, and
a 12-channel server in this case will
provide one workplace with 10REC
+ 2PLAY / PLAY + SEARCH or 4REC
+ 2PLAY / PLAY + SEARCH with two
operators/workplaces. When working
on a team tournament like CS: GO, you

Slomo TV replay
control workstation

need at least 12 recording channels
of 5 cameras - one camera for each
player of both teams, and 2 channels
for recording selected images from
the computers of players on different
teams. This is the minimum set. Some
directors increase the number of
recorded channels to 15. When servers
with 6 or 8 channels are used, you will
need 3 to 4 servers for the broadcast.
Dynamic Play
In classic sports such as football or
basketball, the use of several servers
and several operators does not cause
any problems. Important events
are relatively rare, they are focused
around one place and one moment in
time and there is always time for the
operators, each on its own server, to
select the necessary camera, mark
the clips and then, according to
the director commands, in concert
broadcast replays.
In e-sports, everything is much
more dynamic and complex, in less
than two minutes a full-fledged battle
takes place, the events of which are
distributed in space, and occur in
parallel. The fights go one after one
until 15 wins. The breaks between them
are very short - 15 to 30 seconds. And
in such conditions, you need to replay
the necessary moments from different
random cameras. The classic multicamera setup with a replay director
does not work - there is very little time
for coordination.
In this case, it becomes important
to provide the replay operator, while
working with 12 to 15 3G recording
channels, a tool that allows very
quickly finding the right moments on
any camera and instantly replaying
them.
High channel performance 15REC
+ 15SEARCH + 2PLAY + FX in one
server - Dominator AT/3G allowed
it to work simultaneously with all
needed for replays videos. From the
very first slomo.tv server created in
2005, we have decided to use separate
dedicated search channels, which will
work on a standard computer graphics
monitor.
