1. Overview

1.1 PRODUCT DESCRIPTION

Epsio is a graphics solution integrated into the MulticamLSM that allows the operators to control graphic animations, such as offside line, graphic overlays, arrows or circles, using the LSM Remote Panel.
It can be used with the EVS XT family servers and works with Multicam, from version 10.2.30 onwards.
Before the event, the use r performs the initial calibration, where the images of the playfield are matched with predefined angles into the system. Based on this calibration, Epsio is able to instantly and automatically recognize the playfield during actions when the playfield is clearly visible on the video signal. The user will also define the chroma key, which means the range of colors on the video signal where the graph ic animations will be incrusted.
The operator can then trigger the animation in a one-second operation, using the jog wheel of the LSM Remote Panel.
The producer can automatically see a screenshot with the graphic animation, and decide whether or not to play out the entire action with the effects.
Important If you want to use the live tools in Epsio, you need to have the Live
Tools license inst alled in XSecure.

1.2 CABLING

The schema on the following page shows how the Epsio workstation and the EVS server BNC cables should be connected:

2.3 CALIBRATING THE CAMERAS

2.3.1 INTRODUCTION

In Epsio, calibrating the cameras consists of positioning a virt ual playfield in a 3D environment to match the position of the actual playfield used for a given event. You calibrate the came ras in the Calibration t ab in Epsio.
OFFSIDE LINE CALIBRATION
When you use the offside line too l, you usually cal ibrate two 16-meter cameras for an event: a left-angle camera and a right-angle camera. However, Epsio allows you to use other cameras.
You calibrate each 16-meter camera on two angles: looking at the goad area, and at the central circle.
LIVE TOOLS CALIBRATION
When you use the live tools, yo u calibrate the camera that is directly conn ected to Epsio via the IN2 Connector. For this physical camera, you will calibrate a main camera in Epsio. The three angles (left, center and right) are automatically added to the Camera Angle Li st when you add a mai n camera in the Calibration t ab.
Important
Only calibrate your cameras when you have validated position, height and orientation. These should no longer change after the calibration.

2.3.2 CALIBRATION TAB

OVERVIEW
The following table gives a short explanation on each area of the Calibration tab displayed below:
Area Description
Camera Creation This area allows you to add cameras, and assign them to a
recorder channel on an EVS server. See also the section ‘Camera Creati on Area’, on page 19.

2.3.3 HOW TO CALIBRATE THE CAMERAS

Note
The calibration steps explained in the sections below illustrate the calibration of the two 16-meter cameras used with the offside line tool. However, the same procedure applies to the calibration of the free camera for the live tools .
Once Epsio is open, you calibrate the various cameras in the CALIB tab, in the following way:
1. Add a virtual camera for each physical camera to be calibrated, by clicking
the Add butt on corresponding to the requested camera in the Creation area:
The camera angles to be calibrated for the corresponding camera preset are added as frames includ ing the virtual playfie ld in the Camera Angle lis t:
2.
Using the Preview channel, make snapshots corresponding to each calibration angle in the f ollowing way:
a. In the Camera Angle list in Epsio, click the camera angle to which you
want to associate a sn apshot.
b. Pause on the requested frame in the previe w channel.
Issue 1.63.C
EVS Broadcast Equipment – May 2011
24
and drag it to the corresponding position on the real
c. Click in the Current area in Epsio. For more information, refer to the section 2.3.4 ‘Snapshots for Calibration,
on page 25.
3. For each camera angle, perform a rough calibration, by matching four non-
contiguous virtual anchor points to the real position in the playfield as follows:
• Right-click a virtual anchor point (crosses on the lines) on the requested
camera angle playfield, then relea se.
A light blue line is drawn between the virtual point and the matched point on the snapshot:
Once the fourth point h as been matched, the virtual play field is automatically superimposed t o the snapshot.
For more information on the four points to be matched, and on the possible actions with the mouse, refer to the section 2.3.5 ‘Recommendations for Matching the Virtual Playfield to the Real One’, on page 30.
4. To refine the calibration of a virtual point, do t he following:
a. Position the mouse around the virtual point (it is surrounded by a red
circle).
b. Use the Arrow keys on the keyboard to adj ust the virtual point.
5. Adjust the playfi eld size if necessary:
• Check that touchlines are not too long or too small on the four calibration
angles, and if necess ary adjust the playfield widt h.
• Check that the central circle is not too large or small on the two central
calibration angles, a nd it necessary adjust the p layfield length.
Click the menu File > Save to save the configuration. The default location
6.
where configurations are stored is C:/Program Files/ EVS Broadcast Equipment/Epsio/Config.
EVS Broadcast Equipment – May 2011

25
The camera angles defined in Epsio are now associated to snapshots of the real playfield and saved in a configuration file. You can load them back via the File > Load menu. See also the section Configuration’, on pag e 11.
7. Use varied test snapshots to make sure the calibration is acceptable as a
whole. If necessary, perform some adjustments by repositioning only the anchor points initial ly matched in step 3.
For more information on the calibration tests, see the section 2.3.6 ‘Testing your Calibration’, on page 34.

virtual points for offsid e shots where playfield lines would not be visible. For more information on additional virtual points, see the section 2.3.7
‘Adding Virtual Points’, on page 37.

2.3.4 SNAPSHOTS FOR CALIBRATION

2.1.3 ‘Saving and Managing the
16-METER CAMERA CALIBRATION
Introduction
For each 16-meter camera used for the offside feature, you need to take two snapshots correspondin g to each camera angle:
• Goal area
• Central circle
Important
Keep the following in mind when you select the fra me you will use:
• A playfield is naturally curved, whereas the Epsio virtual field is made
up of straight lines.
• A very wide shot is very likely to distort the image, which will in tensify
the curved effect of the field.
Goal Area Cali bration
The snapshot for the goal area of the left or right 16-meter cam era should show:
• the whole left or right penalt y area (respectively) with the 16-meter and 6-meter
lines
• the goal line al ong the goal area,
• part of each touc hline on both sides of the playfield.
Issue 1.63.C

MAIN CAMERA CALIBRATION
You need three calibra tion shots to calibr ate the central camera:
• Left penalty area
• Central circle
• Right penalty area
Important
Keep the following in mind when you select the fra me you will use:
• A playfield is naturally curved, whereas the Epsio virtual field is made

2.3.6 TESTING YOUR CALIBRATION

GENERAL TEST FOR A 16-METER CAMERA
Once you have calibrated all your camera angles, it is recommended to test them using test snapshots of the playfield.
A general and quick t est consists of drawing an offside line, and rolling it over the calibration shots, to ensure that the offside line matches the foll owing lines of the field:
• the 16-meter line
• the 6-meter line
• the half-w ay line
Systematic tests based o n test snapshots are explained in details below.
TESTING TH E GOAL AREA
1st Test
Using the same view as your calibrati on shot, take an offsi de shot. Check that the 16-meter line and 6-meter line are cor rectly matched. If necessary, reposit ion the faulty anchor poi nts.
2nd test
Move the camera to the bottom corner arch without changing the zoom.
EVS Broadcast Equipment – May 2011
Issue 1.63.C
35
Check that the 16-meter line and 6-meter line are cor rectly matched.
3rd test
Move the camera back to the goal area, keeping the 6-meter and 16-meter lines.
All lines must match. If the tests are not satisfactory, refine the calibration by matching several
calibration points again. Each time you modify your calibration, you need to perform the tests again.
When you do not achieve perfect results using calibration points, you can modify the advanced se ttings for the camera positio n in the Current area to fine-tune your calibration. These parameters allow a global modification of the calibration for each camera, taking into account the X, Y, Z position, as well as the orientation with the pan, tilt and roll angles. See also the description of the Advanced group box in the section ‘Current Camer a Area’, on page 20.
Issue 1.63.C
EVS Broadcast Equipment – May 2011
36
TESTING TH E CENT RAL CIRCLE
All lines must be correctly matched on the calibration shot. Besides this, you should test three add itional test shots:
1st test
Using the same view as your calibration shot. Check that the central ci rcle is correctly matched, and t hat the borders of the half-
way line are corre ctly matched. If necessary, reposit ion the faulty anchor poi nts.
2nd test
Center the camera on t he half-way line to see the whole line.
When you draw an offside line on this shot, the virtual line should touch both ends of the half-way line. Due to the natural playfield curve, the offside line may not fully correspond to t he half-way line ar ound the middle of the li ne.
EVS Broadcast Equipment – May 2011
Issue 1.63.C
37
3rd test
Move and zoom the came ra to view the 6-m eter line, and part of th e half-way line. Use this test shot to add your additional virtual p oints.

2.3.7 ADDING VIRTUAL POINTS

PURPOSE
When Epsio is not able to automatically detect the playfield limits, the operator has to validate the playfield limits manually as ex plained in the section 3.2.2 ‘How to Validate the Playf ield Limits’, on page 63.
In extreme cases, shots do not display any playfield line. This is the case, for example, with a close-up between the centra l line and the 16-meter li ne, as shown below:
In such a situation, you can use additional points, which are not included in the original mapping model , to validate the playfi eld limits.
It is recommended to add the additional poi nts at this stage of the calibration.
Issue 1.63.C
EVS Broadcast Equipment – May 2011
38
RULES
Follow the rules specified below whe n you add virtual points:
• The additional virtual points are only added to the calibration of the camera
angle you are edit ing. You will not be able to use the addi tional virtual points on other camera angles.
• Choose the additional virtual points using positions that you will easily identify
during the live event, that is to say the stadium geometry: first step of the terracing, static ban ners around the field, etc.
• Add at le ast two additional virtua l points.
• To add virtual points for the central circle, for example, you can use a shot
similar to the snapsho t used for the 3
rd
calibratio n test of the central circ le.
PROCEDURE
To define an additional virtual point, press CTRL + click where you want to add the point on the cali bration shot.
TEST
To test the addit ional virtual points, p roceed as follows:
1. Select a shot on which you barely see the playfield lines (typically with the
upper part of the hal f-way line and a portion of th e 16-m eter line).
2. Press SHIFT + D on the Remote Panel.
3. Reposition manually th e virtual playfield on the shot u sing the visible playfield
lines.
You can then check that the additional virtual points are correctly placed, and match the requested position. Otherwise, go back to the calibration shot, and modify the position o f the wrong additional poi nt.

2.4 CONFIGURING THE CHROMA KEY

2.4.1 GENERAL INFORMATION

CONCEPT O F CHROMA KEY
The chroma keying is a technique for compositing two images or frames together in which a color (or a range of colors) from the main image (video signal) is removed (or made transparent), revealing another image behind it. The key is the image that punctures t hrough the image of the video signal.
In Epsio, you select the green color of the playfield (or a range of green) and replace it by the key layer. The key layer will defi ne how the offsi de line animation will be displayed:
• All that is white in the key layer will n ot be incrusted.
In the final result, the key is transparent and the main image will show.
• All that is black in the key layer will be incrusted with the offside line anim ation.
In the final result, the main image is covered by the offside line animati on.
• The more an area is black, th e more the incrusted materi al will show.
In summary, when you define the chroma key, you define the color or color range in the video signal t hat will be replaced by t he offside line animatio n.

IMPACT OF LIGHT CONDITIONS
As the chroma key depends on the light, it is recommended to configure the chroma key 30 minutes before the match to get the closest to the light conditions that will prevail dur ing the match.
For a match during the day, you should perform two chroma key configurations: one for light, one fo r dark, to allow you to cope with shadows on the p layfield.
In case you have a bright light, but a large shadow across the field (for example the top of the stadium roof structure), you can also make a chroma key matching light and shadows, in which case the player s would be under the graphics.
For a match during the night, you can configure a chroma key as soon as the sun is down and the stadi um lights are on.
RECOMMENDATIONS
You can define th e chroma key:
• in the chroma key edit screen on the LSM Rem ote Panel
• in the CHROMA t ag in Epsio.
It is recommended to configure the chroma key using the Remote Panel. For this reason, we will provide minimal information on the chroma key definition using the CHROMA tab in Epsio.

2.4.3 CHROMA KEY PARAMETERS

You can create and manage up to four chroma key definitions from the LSM Remote Panel, or in Epsio, using the chroma ke y profiles.
The various chroma key parameters allow you to define or refine a chroma key profile.
The representation of the chroma key definition in a color space will help you visualize the range o f colors taken into accoun t in the chroma key def inition.
REPRESENTATION OF TH E CHROMA KEY IN EPSIO
A YUV color space is displayed on the CHROMA tab in Epsio to represent the color range selected i n the chroma key:
The chroma key definit ion is represented as f ollows on the color space:
• The black box in the color space corresponds to the colors that are totally
removed on the chroma k ey layer (black).
• The colors between the black and white boxes in the color space correspond to
the transition color range, in other words to the colors that will be more or less removed on the chroma k ey layer. The white bo x is clearly displaye d in Epsio.
• The colors outside the white box in the color space correspond to the colors
that are not removed on the chroma key layer (white) .
REPRESEN TATION OF THE CHROMA KEY ON THE MONITOR
A YUV color space is displayed on the top left corner of the monitor to represent the color range selected in the chroma key. It contains additional scales, with ‘sliders’ to reflect the hue, saturation and black level (or brightness) of the selected color range. The grey box displayed on the color space represents the selected color range.
EVS Broadcast Equipment – May 2011

DEFINITI ON OF THE CHROMA KEY PARAMETERS
The chroma key parameters are explained in the t able below:
Parameter Description
RGB Hue Value Definitio n X Moves left and right the color range in the col or space.
Y Moves up and down the color range in the color space. Tolerance Definition Width (W) Widens or narrows the color range on the X axis in the
space.
Height (H) Widens or narrows the color range on the Y axis in the
space. Transition Definiti on X Transition (TX) Widens or narrows (on the X axis) the color range that will
be more or less punctu red when defining the key l ayer. Y Transition (TY) Widens or narrows (on the Y axis) the color range that will
be more or less punctu red when defining the key l ayer. Black Level Adjusts the level of transparency of the graphic animation,
in other words defines how strong the animation will be
displayed.

2.4.6 METHODS AND RECOMMENDATIONS FOR THE CHROMA KEY DEFINITION

METHODS
There are several ways to configure your chrom a key. This section will explain the two main me thods:
• Defining a chr oma key based on an automati cally generated chroma key.
• Defining a chr oma key based on an area se lected on a playfield.
STEPS
In both methods, you need to go through the follo wing steps:
1. Creating an offside l ine.
2. Accessing the Chroma Ke y edit screen.
3. Generating the initial chroma key definition.
4. Saving the initial chroma key definition in a profile.
5. Opening the ch roma key profile.
6. Refining the init ial chroma key definition.
7. Saving the final chroma key definition in the loaded profile or in a new one.
RECOMMENDATIONS AND TIPS
In the Chroma Key edit screen, the F8 function allows you to toggle between the chroma key layer (white/black display) and the representation of the final incrustation on the video signal (color display).
It is recommended to:
• Use the chroma key layer to define the chroma key parameters from F1 to F6.
• Toggle to the final incrustation to refine the black level parameter (F7).
Note
If you cannot see the representation of the final incrustation, this means you need the limits of your playfield could not be automa tically validated. You need to validate them manually. See the section 3.2.2 ‘ Validate the Playfield Limits’, on page 63.

2.4.7 HOW TO CONFIGURE A CHROMA KEY BASED ON AN AUTOMATIC CHROMA KEY

The automatic chroma key is based the colors located within the virtual playfield. For this reason, the virtual playfield must be correctly matched to the real playfield on the snap shot you will use for the aut omatic chroma key.
To configure a chr oma key based on an automatic chroma k ey, proceed as follows:
1. In the main operation al menu, jog to an image of the real playfield th at you will
use for the chroma key configuration.
2. Press SHIFT+D t o enter the Epsio menu.
3. If the virtual playfield is not correctly matched to the real playfield, do one of
the following:
o Valida te the field limits as explained in th e section 3.2.2 ‘How to Validate the
Playfield Limits’, on page 63.
o Make an offside animation as explained in the section 3.2.3 ‘How to Create
an Offside Line Animat ion’, on page 64.
4. Press SHIFT+B t o enter the Chroma Key edit screen.
F1: X F5: X Transition F2: Y F6: Y Transition F3: Width F7: Black Level F4: Height F8: Toggle View
5. Press SHIFT+A (Auto) to generate an automatic chroma key on which you will
base your chroma key configuration.
6. Press SHIFT+C (Save As), then press A, B, C or D to select the profile in
which you want to save the automatic chroma key definition.
7. Press the key corresponding to the profile on which you have just saved the
automatic chroma key definition. The automatic chroma ke y is loaded onto the operator’s PGM. You can now
refine it.
8. Press the function key corresponding to the parameter you want to modify and
jog the wheel to modif y the parameter value as re quested. In this step, you can press F8 w hen you want to toggle betw een the key layer
and a represen tation of the final incrustation .
9. Repeat step 8 for all parameters you want to adj ust.

2.5 ADDING AND CUSTOMIZING THE GRAPHIC SUITE

2.5.1 GRAPHIC SUITE DEFINITION AND COMPONENTS

The graphic suite includes the graphic packs for the various tools you can use in Epsio (offside, arrow, cir cle, graphics).
The graphic pack contains the definition of the components of a given Epsio graphic tool, in othe r words this is the gr aphic chart of the tool.
A series of template graphic packs is available for each graphic tool. When the graphic pack is loaded, its various targets (components) can be customized to your needs.
The following schema gi ves you an overview on the el ements included in a graphic suite, and how they are hierarchically organized. The customization is performed at the level of the target parameters. The schema does not show all possible targets and target pa rameters for the availab le tools.
To be able to perform an animation in Epsio, you need to define and load a graphic suite. You wi ll create, load and modify your gr aphic suite from the TOOLS tab in Epsio. Once the graphic suite has been loaded in Epsio, the same suite is automatically load ed each time Epsio is starte d.

INTRODUCTION
Based on the calibration performed, the playfield limits are automatically detected and matched to the virtual playfield when you enter the offside line mode. In this case, the virtual pla yfield lines are displa yed in red.
If the image on which you want to create your offside line is slightly blurred, or does not display enough lines on the playfield for the automatic detection to work properly, the virtual playfield will be made of white lines.
If the auto-detection of the playfield does not work (white lines) or if the virtual playfield lines are not perfectly matched to the real playfield, you first have to validate the playfield limits. This action consists of repositioning the virtual playfield limits onto the real playf ield limits.
