USER MANUAL Epsio Live 1.70

Overview 1

1. Overview

1.1 Product Description

Epsio Live 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 user 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 graphic 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.

Warning

If you want to use the live tools in Epsio, you need to have the Live Tools license installed 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 virtual playfield in a 3D environment to match the position of the actual playfield used for a given event. You calibrate the cameras in the Calibration tab in Epsio.

Offside Line Calibration

When you use the offside line tool, you usually calibrate 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, you calibrate the camera that is directly connected 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 List when you add a main camera in the Calibration tab.

Warning

Only calibrate your cameras when you have validated the camera position, height and orientation. These should no longer change after the calibration.

2.3.2 Calibration Tab

3. Click in the Current area in Epsio.

For more information, refer to the section 2.3.4 ‘Snapshots for Calibration, on page

23.

For each camera angle, perform a rough calibration, by matching four noncontiguous 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 and drag it to the corresponding position on the real playfield, then release.

A light blue line is drawn between the virtual point and the matched point on the snapshot:

Once the fourth point has been matched, the virtual playfield is automatically superimposed to 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 28.

To refine the calibration of a virtual point, do the following:

1. Position the mouse around the virtual point (it is surrounded by a red circle).

2. Use the Arrow keys on the keyboard to adjust the virtual point.

Adjust the playfield size if necessary:

• Check that touchlines are not too long or too small on the four calibration

angles, and if necessary adjust the playfield width.

• Check that the central circle is not too large or small on the two central

calibration angles, and it necessary adjust the playfield length.

6. Click the menu File > Save to save the configuration. The default location where

configurations are stored is C:/Program Files/ EVS Broadcast Equipment/Epsio/Config in Windows XP (or equivalent for Windows 7).

on page 10.

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 initially matched in step 3.

For more information on the calibration tests, see the section 2.3.6 ‘Testing your Calibration’, on page 32.

On a shot that includes the 16-meter line, and part of the central circle, add virtual points for offside shots where playfield lines would not be visible.

2.3.4 Snapshots for Calibration

16-Meter Camera Calibration

Introduction

For each 16-meter camera used for the offside feature, you need to take two snapshots corresponding to each camera angle:

• Goal area

• Central circle

Warning

Keep the following in mind when you select the frame 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 intensify the

curved effect of the field.

Goal Area Calibration

The snapshot for the goal area of the left or right 16-meter camera should show:

• the whole left or right penalty area (respectively) with the 16-meter and 6-meter lines

• the goal line along the goal area,

• part of each touchline on both sides of the playfield.

Warning

The touchlines should be parallel to the horizontal borders of the frame, and the zoom should keep the distortions of touchlines as low as possible.

• To delete a virtual point, click on it.

• To add a virtual point, press CTRL + click on the virtual field at the position where the

point should be added.

• To remove a virtual point you have added, click on it.

Additional Tips

Here are the following tips to help you in this step:

• Once you have selected a virtual point, you can adjust its position in one of the

following ways:

o Pressing the arrow keys on the keyboard for small increments

o Pressing simultaneously SHIFT and the arrow keys on the keyboard for bigger

increments.

• When the mouse pointer is close to a virtual point, a red circle surrounds it, and the

arrow keys on the keyboard are automatically activated to enable you to adjust the point.

EVS Broadcast Equipment SA

Issue 1.70.A February 2014

32 Configuration

• The four anchor points you use to calibrate a camera angle should not be aligned.

• Always match the points to the same edge of the lines.

• You can use more than 4 points to perform the calibration.

• If the 2

and 3rd tests of the goal area calibration for a given camera are excellent, you can use the position parameters (x,y,z) of this camera angle for the central circle calibration of the same camera.

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 test consists of drawing an offside line, and rolling it over the calibration shots, to ensure that the offside line matches the following lines of the field:

• the 16-meter line

• the 6-meter line

• the half-way line

Systematic tests based on test snapshots are explained in details below.

Testing the Goal Area

1st Test

Using the same view as your calibration shot, take an offside shot.

Check that the 16-meter line and 6-meter line are correctly matched.

If necessary, reposition the faulty anchor points.

USER MANUAL Epsio Live 1.70

Configuration 33

2nd test

Move the camera to the bottom corner arch without changing the zoom.

Check that the 16-meter line and 6-meter line are correctly 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 settings for the camera position 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 Camera Area’, on page 18.

EVS Broadcast Equipment SA

Issue 1.70.A February 2014

34 Configuration

Testing the Central circle

All lines must be correctly matched on the calibration shot. Besides this, you should test three additional test shots:

1st test

Using the same view as your calibration shot.

Check that the central circle is correctly matched, and that the borders of the half-way line are correctly matched.

If necessary, reposition the faulty anchor points.

2nd test

Center the camera on the 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 th e half-way line. Due to the natural playfield curve, the offside line may not fully correspond to the half-way line around the middle of the line.

USER MANUAL Epsio Live 1.70

Configuration 35

3rd test

Move and zoom the camera to view the 6-meter line, and part of the half-way line.

Use this test shot to add your additional virtual points.

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 explained in the section 3.2.2 ‘How to Validate the Playfield Limits’, on page 62.

In extreme cases, shots do not display any playfield line. This is the case, for example, with a close-up between the central line and the 16-meter line, as shown below:

In such a situation, you can use additional points, which are not included in the original mapping model, to validate the playfield limits.

It is recommended to add the additional points at this stage of the calibration.

EVS Broadcast Equipment SA

Issue 1.70.A February 2014

36 Configuration

Rules

Follow the rules specified below when you add virtual points:

• The additional virtual points are only added to the calibration of the camera angle you

are editing. You will not be able to use the additional 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 banners around the field, etc.

• Add at least two additional virtual points.

• To add virtual points for the central circle, for example, you can use a shot similar to

the snapshot used for the 3

calibration test of the central circle.

Procedure

To define an additional virtual point, press CTRL + click where you want to add the point on the calibration shot.

Test

To test the additional virtual points, proceed as follows:

1. Select a shot on which you barely see the playfield lines (typically with the upper part of the half-way line and a portion of the 16-meter line).

2. Press SHIFT + D on the Remote Panel.

3. Reposition manually the virtual playfield on the shot using 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 of the wrong additional point.

2.4 Configuring the Chroma Key

2.4.1 General Information

Concept of 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 through 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 define how the offside line animation will be displayed:

• All that is white in the key layer will not 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 animation.

In the final result, the main image is covered by the offside line animation.

• The more an area is black, the more the incrusted material will show.

In summary, when you define the chroma key, you define the color or color range in the video signal that will be replaced by the offside line animation.

EVS Broadcast Equipment SA

Issue 1.70.A February 2014

38 Configuration

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 during the match.

For a match during the day, you should perform two chroma key configurations: one for light, one for dark, to allow you to cope with shadows on the playfield.

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 players 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 stadium lights are on.

Recommendations

You can define the chroma key:

• in the chroma key edit screen on the LSM Remote Panel

• in the CHROMA tag 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 key 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 of colors taken into account in the chroma key definition.

Representation of the Chroma Key in Epsio

A YUV color space is displayed on the CHROMA tab in Epsio to represent the color range selected in the chroma key:

The chroma key definition is represented as follows on the color space:

• The black box in the color space corresponds to the colors that are totally removed

on the chroma key 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 key layer. The white box is clearly displayed 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).

Representation 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.

USER MANUAL Epsio Live 1.70

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 automatically validated. You need to validate them manually. See the section 3.2.2 ‘How to Validate the Playfield Limits’, on page 62.

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 snapshot you will use for the automatic chroma key.

To configure a chroma key based on an automatic chroma key, proceed as follows:

1. In the main operational menu, jog to an image of the real playfield that you will use for

the chroma key configuration.

2. Press SHIFT+D to enter the Epsio menu.

3. If the virtual playfield is not correctly matched to the real playfield, do one of the

following:

• Validate the field limits as explained in the section 3.2.2 ‘How to Validate the

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, circle, graphics).

The graphic pack contains the definition of the components of a given Epsio graphic tool, in other words this is the graphic 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 gives you an overview on the elements 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 parameters for the available tools.

To be able to perform an animation in Epsio, you need to define and load a graphic suite. You will create, load and modify your graphic suite from the TOOLS tab in Epsio. Once the graphic suite has been loaded in Epsio, the same suite is automatically loaded each time Epsio is started.

3.3.1 ‘How to Activate a Live Tool‘, on page 65.

The Graph feature is active by default.

The Mark key is blinking red on the LSM Remote Panel.

The virtual playfield is displayed on the operator’s PGM.

Note

If the playfield limits are automatically detected, the virtual playfield lines are red. Otherwise, the virtual playfield lines will be white. In this case, you first need to validate the playfield limits manually.

3.2.2 How to Validate the Playfield Limits

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 playfield lines are displayed 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 playfield limits.

USER MANUAL Epsio Live 1.70

Creating Graphic Animations 63

Procedure

To validate the playfield limits, proceed as follows:

1. When you have entered the offside line mode, right-click one of the points on the

virtual field. This can be a virtual point you have added during the calibration.

2. Drag the virtual field to match the real playfield.

3. Release the mouse.

4. Use the mouse wheel to adjust the zoom.

The real playfield limits have been validated, and the virtual playfield lines are now displayed in red on the monitor.

3.2.3 How to Create an Offside Line Animation
