1 Introducing PresStation

What is PresStation?

resStation is a powerful master-control switching and branding system
designed for automated, multi-channel environments. It is designed to

control the Imagestore automated master control and channel branding
system used by many of the world’s largest broadcaster s for mor e than 800
transmission channels worldwide.

PresStation includes a variety of features including:
♦ multi-channel control (up to 24 channels can be controlled by a single

operator)

♦ channel branding (including animated logo and clock insertion, Squeezy

DVE and networked image distribution (using the Imagestore Media
Manager software)

♦ video and audio switching
♦ a robust and scalable control system

Multi-channel control

With a PresStation system you can control up to 200 transmission channels
from a single panel or you can simply operate a single transmission channel
manually.

Channel branding

PresStation can control up to four keying layers per channel, which you can
use to insert stills and animations including logos and in-vision clocks and
timers. You can use the Squeezy DVE option for picture-in-picture
applications such as over the shoulder news transitions as well as squeezes
for schedules, credits, news flashes an d sp orts results. You can also use the
windows-based (2000 and XP) Imagestore Media Manage software to
browse and distribute remote image and audio files via the Ethernet.

P

Introducing PresStation PresStation User Manual

Page 20 Miranda Technologies Ltd

Video and audio switching

The PresStation switcher can control up to 10 source inputs fed from an
external dedicated router or a large station router shared amongst multiple
channels. For example, you can scroll through the inputs of a large router and
access 10 feeds at any one time. You can switch by cutting, fading and
wiping auto-transitions. PresStation also enables you to control full group
digital audio mixing and two stereo voice-overs. You can also store and play
out up to 400 minutes of digital stereo audio inserts and voice-overs if you
have the Easyplay option fitted to your Imagestore system.

Control system

PresStation includes a robust and highly scalable control system. Each
PresStation control panel must be connected to one (or up to 6) Presmaster

Control Unit(s) PCS-001 to provide interfacing to:

♦ Imagestore or Intuition channel-branding systems
♦ external router(s)
♦ automation system(s)
♦ Sony 9 pins

Each Presmaster Control Unit PCS-001 can control up to 4 channels, so by
linking 6 Presmaster Control Units to a single panel up to 24 transmission
channels can be controlled by the user.

Each Presmaster Control Unit PCS-001 can control up to two Imagestores or
one Imagestore and one Intuition (in series) per transmission channel (and up
to 8 in total (2 x 4 channels)) to provide up to four keying layers. Each
Imagestore provides two independent keying layers and storage for up to
4000 animations, stills or clocks.

3 Doing a Simple Presentation

lthough up to 24 transmission channel s can b e controlled from one
PresStation panel and up to 10 different output sources (at one time)

per channel, you can also use the PresStation panel to simply
switch/cut between different sources to change your current programme
output (that is, what is currently going to air).

This method is useful if you are only working with a limited number of
sources (that is, a minimum of two and maximum of ten) and you are not
concerned about checking a source before it goes to air.

PresStation has two rows of 10 buttons (buses) for selecting and switching
between sources. The yellow PST buttons enable you to choose and preview
other available sources before going to air. However, you only need to use
the red programme (PGM) buttons in the middle row to control the current
programme output.

A

Doing a Simple Presentation PresStation User Manual

Page 38 Miranda Technologies Ltd

The button for the PGM source, which is currently going to air is lit up (the
name of the source is displayed at the top of the three rows of buttons).

Note: This BUS is distinguished in red to denote ‘On-Air’.

How to cut to a different programme source

To cut to a different source:

♦ press the appropriate red PGM source button
♦ the new button lights up and the previous source button light goes out
♦ the programme output automatically cuts to the source you have just

chosen

If you simply use the PGM buttons to cut to different output sources you do
not get the chance to check the source before you go to air. If you want to be
able to preview your next source before going to air you will need to use the
set of PST (preset buttons). For more information see Chapter 4 Doing a
Presentation with a Transition below.

PresStation User Manual Doing a Presentation with a Transition

Miranda Technologies Ltd Page 39

4 Doing a Presentation with a

Transition

n the previous section you learned how to do a simple presentation using
only the PGM source buttons to switch/cut between sources. This is fine if

you are only working with a limited number of sources and do not need to
check each source before going to air. However, if you are choosing from a
wider selection of sources or if you want to add a special video eff ect it may
be necessary to look at a preview of a source before going to air. The yellow
PST source buttons on the bottom row enable you to choose and preview the
next source before going to air.

Before you can use the PST source buttons to choose your next source, you
have to tell PresStation how you are going to transfer the preview source to
the current programme output – this is known as a transition.

What is a transition?

The process of switching between two vide o sou rces is
known as a transition. Although PresStation enables you
to make a variety of transitions (all of which are
described in Using Transitions later in this manual) in
this section you will learn how to do a simple cut. The
cut transition button is at the bottom, left-hand corn er of
the bank of transition buttons. For example:

I

Doing a Presentation with a Transition PresStation User Manual

Page 40 Miranda Technologies Ltd

The cut is the most common form of transition. It is where one video source
(or picture) is immediately replaced by another source.

How to choose your preview (PST) source

To choose a preview source:

♦ press the cut transition button (the transition arm LED lights up to show

that it is armed (active))

♦ press the appropriate yellow PST source button (the

name of the source is displayed above the three rows
of buttons)

5 More about Transitions

n the previous section you learned how to replace the current programme

output with a preset source using a simple cut transition.

PresStation, however, enables you to make a variety of transitions using one
of the transition buttons on the PresStation control panel. The different
transition buttons can be grouped into the following basic types:

Cut This is the most common form of transition. It is

where one video source (or picture) is immediately
replaced by another source. This type of transition is
not affected by the transition rate (see Choosing a
Transition rate below).

Fade There are five types of fade – cut-fade, fade-cut, V-

fade, X-fade and U-fade. With a fade there is a
gradual transition from an image to a black screen
or from a black screen to an image.

Wipe This is where one video source (picture) is gradually

replaced (wiped out) by anoth er pi ct ure. De p e nding
on which type of wipe transition you choose, the
current picture is either wiped from side to side (left
to right or right to left) or from top to bottom or
bottom to top.

The transition buttons

Once you have decided on the basic type of transition you want to make (cut,
fade or wipe) you are ready to choose one of the following transition buttons
from the PresStation control panel (note that the following list describes the
buttons and actions set up by Miranda – your set-up/configuration may be
different):

Button Action

The Cut transition button immediately replaces the current
programme output by your chosen pr eset source.

The Cross/Fade transition button produces a standard mix
between the programme output and the preset source.

The Cut/Fade transition button cuts the programme output
to black and then fades it up to the preset source.

The Fade/Cut transition button fades the programme output
down to black and then cuts to the preset source.

The V Fade transition button fades the programme output to
black and then fades from black to the preset source (i.e. it is
effectively two cross fades – the first from programme to
black and the second from black to preset).

The U Fade transition button has the same effect as a V fade
except that you can control the time spent at black by
pressing and holding the TAKE button. When you press
TAKE, the programme output fades to black and then
remains black until you release the TAKE button.

PresStation User Manual More about Transitions

Miranda Technologies Ltd Page 43

The V Wipe transition button gradually wipes over the
current source with the new source. A V wipe can be from
top to bottom or bottom to top depending on how your
system is set up (configured).

The H Wipe transition button has the same effect as a V
wipe except that the wipe is from left to right or right to left
depending on how your system is set up (configured).

The Transition Types and Rates screen

You use the Transition Types and Rates
screen to change the settings of the transition
buttons. You can also change the rate (speed)
at which a transition is made from this screen
(see Chapter 6 Choosing a transition rate for
more information).

To display the Transition Types and Rates
screen, press the white, round dialogue button
to the left of the A/V Split button.

More about Transitions PresStation User Manual

Page 44 Miranda Technologies Ltd

The Transition Types and Rates screen displays details about all the
transition buttons except the cut and cross fade. You can change the settings
of all the buttons displayed on this screen.

Note: The cut and cross fade buttons are not configurable and are

therefore not displayed on this screen.

How to change a transition type setting

To change any of the transition type settings (for example, the in and out
times, the relative times or the wipe softness):

♦ click on the appropriate button
♦ turn the rotary knob (the setting goes up or down depending on which

way you turn the knob)

Note: Changing the out time of a cut fade or the in time of a fade cut will

change the transition type to a V fade.

PresStation User Manual More about Transitions

Miranda Technologies Ltd Page 45

Audio and video only transitions

Usually audio and video signals are used in a transition simultaneously.
However, you can use the Audio Only and Video Only button selection to
specify whether you want a subsequent transition to affect only the audio or
video part of the output (known as an audio/video breakaway).

To select Audio Only press the A/V split button until the orange light to the
left of AUDIO ONLY is lit and then press the Take button. To select Video
Only press the A/V split button until the orange light to the left of VIDEO
ONLY is lit and then press the take button.

When you select Audio Only, the next transition will only affect/change the
audio part of the on-air signal. Similarly, when you select Video Only, the
next transition will only affect/change the video part of the on-air signal.
After you have made an audio only or video only transition both the
programme and preset sources will be on air. If you then choose a different
preset (preview) source, only the output you have chosen (that is, audio or
video) will be affected.

Once the separating transition has been started by selecting either Audio
Only or Video Only and then pressing the Take button the red light to the
right of the effect test that you have selected will light, and the orange light
for the other breakaway effect will be lit. Pressing the Take button again
will complete the transition.

More about Transitions PresStation User Manual

Page 46 Miranda Technologies Ltd

If you do not want to follow an Audio Only transition with a video transition
or a Video Only transition with an audio transition, select the Audio Only or

Video Only again before you do a subsequent take.

Note The breakaway occurs in the upstream Imagestore only, not in

the router.

You use the Lead Audio option (in combination with the Take button) to
add the audio from the preset source with the programme output. You select
the LEAD AUDIO option by pressing the A/V Split button until the orange
LED to the left of LEAD AUDIO is lit and then pressing the Take button.
When you subsequently press Take, the transition is made and the light in the
Lead Audio button goes out.

This is similar to an Audio Only transition (see above), except that both the
programme and preset audio are added and used as the output. When the
Lead Audio button is lit up, the preset audio source is on air and subsequent
cuts on the preset source only affect the audio output.

You use the Lag Audio option (in combination with the Take button) to add
audio from the current program source with the video from the preset source.
You select the LAG AUDIO option by pressing the A/V Split button until
the orange LED to the left of LAG AUDIO is lit and then pressing the Take
button. When you subsequently press Take, the transition is made and the
light in the Lead Audio button goes out.

When the Lag Audio button is lit up, the preset video source is on air and
subsequent cuts on the preset source only affect the video output

You use the Fade button (see bottom left of the screen display) to toggle a
fade to black. Note that when you press the Fade button you are not arming it
for a subsequent transition – it affects the output straight away. The Fade
button is lit up when the output is black and the audio button lit when audio is
silent.

PresStation User Manual More about Transitions

Miranda Technologies Ltd Page 47

You use the Silent button (see bottom right of the screen display) to toggle a
fade to silence. Note that when you press the Silent button you are not
arming it for a subsequent transition – it affects the output straight away. The
Silent button is lit up when the output audio is silent, the video remains
unchanged.

6 Choosing a Transition Rate

hen you make a transition you can also choose the rate (speed) at
which the transition is made. You do this by choosing one of the
three possible rates (slow, medium or fast) next to the Rate button:

When you press the Rate button, PresStation
cycles through each of the three preset rates for
the type of transition you chose.

For the X-fade transition, the preset rate is
stored as fields. All other transition types have
their component part timing expressed as a
percentage of the total X-fade time. For
example, the V-fade down and up times could
be 60% and 82%.

The total time for any transition type does not
have to be 100%. For example, a V-fade with a
down time of 60% and an up time of 82%
would create a transition which lasts 1.42 times
as long as an X-fade. These proportions stay
the same irrespective of the rate (slow,
medium, fast) you choose.

Adjusting the specified rates

You can adjust the specified slow, medium and fast rates (that is, the number
of frames to complete the transition) from the Transition Types and Rates
screen. To display the screen, press the white, round dialogue butto n to the
right of the cut and cross fade transition buttons:

Always Show Source

In manual operation you can only select sources of the current displayed
group but under automation or router RCP control it is possible to select a
source outside of the displayed group. In this situation the illuminated soured
buttons will be turned off as they no longer represent activ e sources.

To monitor out of range sources use the Always Show Source mode which
can be selected from the panel configuration screen. In this m ode, when a
source is selected that is outside of the displayed group either button 1 or 10
(default) is reallocated to that source.

Example:

With group 1 sources displayed and Always Show Source enabled, when the
preset bus changes to source 16 (group 2) PresStation will assign source 16 to
button 10 (default) which now represents the out-of-range preset. The button
will light up and the text displayed for that source will change to that of
source 16. The entire 10th column has become source 16 temporarily. If you
press the 10th button on the PGM bus you are actually cutting to source 16
not source 10. The same is true for the AUX bus.

The 10th button will stay as source 16 for as long as the preset remains on it
and Always Show Source remains enabled. If the preset source moves back to
within the displayed group, for example source 4, button 4 will light up and
the 10th bus will go back to being source 10. If the preset changes to source
17, Always Show Source will still be active and the 10th light will stay lit but
the text source will change to display source 17.

Choosing and Changing your Source PresStation User Manual

Whilst the 10th button is in this mode, the non-followed source (normally
programme) can be switched forward and backward from the temporary
source. The 10th bus will not change until the preset changes. The mode will
remain active until either the source is switched back to within the displayed
group or the feature is turned off from the configuration screen.

he PresStation control panel also enables you to use up to four
Imagestore keying layers for inserting channel branding stills,

animations, in-vision clocks and timers. Each Imagestore has two
independent keying layers, which are linked to the Down Stream Keyer
(DSK) buttons on the control panel. One Imagestore is linked to DSK 1 and
DSK 2. A second Imagestore can be linked to DSK 3 and DSK 4.

Each DSK cluster is identical and they are ordered from left to right. This
means that as the signal travels from left to right; the right-hand DSK is the
last in the chain and is therefore the topmost layer (note that your system may
be set up (configured) differently).

Note: Only DSK 1 and DSK 2 are available unless the channel being

controlled has an extra Imagestore. Only DSK 1 and DSK 2
have DVE capability. If the additional Imagestore has a Squeezy
option fitted, DSK 3 and DSK 4 do not currently have DVE
capability.

Fade Rates enables you to set the number of frames it will take to complete a
fade transition. You can adjust the number of frames for each of the rates
(slow, medium and fast).

Inserting a Picture or Logo PresStation User Manual

Page 66 Miranda Technologies Ltd

How to adjust a fade time

To adjust the fade rate:
♦ click on the Fade Rate parameter you want to adjust (Slow, Medium or

Fast) and the button will turn green

♦ turn the rotary knob on the PresStation control panel (the number of

frames will go up or down depending on way you turn the knob)

♦ click on the button again to accept the change. The button will now go

grey

Note: You cannot choose a fade time, which is in the same range as a

slower or faster time (i.e. they cannot overlap).

CGT

CGT enables you to adjust the clip, gain and transparency parameters. Note
that the CGT parameters are typically only used with Load Live.

Clip Clip is the level under which the key signal will be

forced to black. In a keying process this causes a
total absence of fill video in areas where the
incoming key signal is less than the clip lev e l.

Gain The gain level amplifies the key signal forcing

grey levels towards (and up to) white level. In a
keying process this causes the fill signal to be less
transparent than it usually would be in areas with a
grey signal.

Transparency The transparency level controls the amount of

background video that can seep through the keyed
image (for the whole picture).

How to adjust the clip, gain or transparency

To adjust the clip, gain or transparency:
♦ click on the parameter you want to adjust (Clip, Gain or Trans) and the

button will turn green.

PresStation User Manual Inserting a Picture or Logo

Miranda Technologies Ltd Page 67

♦ turn the rotary knob on the PresStation control panel (the level goes up

or down depending on the way you turn the knob).

♦ Click on the button again to accept the change. The button will now go

grey.

Keying

This mode enables you to adjust the key source, key mode and key invert
parameters. Note that these parameters are typically only used with Load
Live.

Key Source When the Key Source parameter is set to Key, the

key data is derived from the luminance content of
the separate key image.
When the Key Source parameter is set to Self, the
key data is derived from the luminance content of
the fill image.
When the Key Source parameter is set to None, the
key for an image is white (i.e. there is no image
transparency).

Key Mode When the Key Mode parameter is set to Full, the

foreground image is passed only when the key
signal is present.

When the Key Mode parameter is set to Linear,

the background and foreground are summed and
the foreground is unaffected by the key.

Key Invert When the Key Invert parameter is set to Normal, a

black-level key signal creates a fully transparent
fill image which is not visible over a background
whereas a white-level key signal creates an
opaque fill image where the background is not
visible though the image.

When the Key Invert parameter is set to Invert, a

white-level key signal creates a fully transparent
fill image and a black-level key signal creates an
opaque fill image (the opposite/inverse of
Normal).

To disarm a macro prior to a take command, press the relevant flashing
button(s).

DVE (Squeezes) are controlled in an identical manner whereby the Squeeze
move is stored as a GPI command on the Imagestore. These can be
programmed to perform a range of squeezes, pans, wipes and similar effects
on full-motion SDI video in real time. For example, you can use it for
picture-in-picture applications such as over the shoulder news transitions as
well as squeezes for credits, news flashes, sports results and schedules.

How to edit a preset position

To edit one of the 100 preset positions, touch the Preset button then turn the
rotary knob until the required number is displayed. Press GET & EDIT and
the Preset parameters will be displayed on screen and the wire frame will
display the current Squeezy position.

To adjust the preset use the buttons on the right hand side of the display in
conjunction with the rotary knob:

♦ X pos position to centre of squeeze image relative to screen width

(50% = screen centre)

♦ Y Pos position to centre of squeeze image relative to screen height

(50% = screen centre)

♦ Width width of squeeze image relative to screen width

(100% = full screen)

♦ Height height of squeeze image relative to screen height

(100% = full screen)

♦ Ratio Free / Ratio Locked Controls the aspect ration of the squeeze

image relative to the screen size.

♦ Revert resets the squeeze image to full screen, centrally placed

X=50, Y=50, W=100, H=100

♦ Preview LIVE pressing this button will display a preview of the preset

being modified on the preview monitor. This is displayed in the form of
a crop not an actual hardware squeeze, but does display the actual
position of the Squeeze on the preview.

♦ Preview Mode, pressing this button changes the mode of the preview.

Options are: B over A, A over B, Reveal MG Store, Reveal FG Store,
Squeeze MG Store and Squeeze FG Store.

To exit the window, touch the ‘Title Bar’ at the top of the screen.

Entering a GPI on the Imagestore

This example sets up a squeeze transition on GPI 1 On and an unsqueeze on
GPI 2 On:

♦ From the Imagestore front panel select:

Set-up -> GPI Setup -> GPI Inputs Assign

♦ Go into the GPI Inputs Assign menu and select the GPI (1 -> 9) you want

to set. Its easiest to choose one of the first 6 as these are mapped by
default to the 6 Macro buttons on the Prespanel.
For this example, select GPI 1
Select the ON part of the GPI (the off part is not used)

♦ NO ACTIONS SET will appear in the display (providing that the GPI is

empty). Press the enter key then press enter again to insert an action.
In this example, select [squeezy] -> Squeeze mode 0 -> Reveal MG
Store. After pressing enter, VGPI 1 will now contain the squeeze mode,
but not the squeeze move. To add the squeeze move press the right hand
arrow key to display END OF LIST. Press enter and enter ag ain to insert
the next command after the previous one.
Select [squeezy] -> Squeeze move 0 -> 1.
You have now defined a VGPI macro that the Prespanel can arm and
take.

♦ Repeat the above process this time adding

[squeezy] -> Squeeze move 0 -> 0 to GPI 2 On
NOTE, squeeze move to 0 will always undo any squeeze.

There are 32 GPIO channels with 16 channels available on each connector.
However, note that GPIO connectors C and D share signals with GPIO
connectors A and B (that is, GPIO 0 signal on connector GPIO C is a
duplicate of GPIO 0 signal on connector GPIO A).

There are also 8 analogue fader inputs in two groups of 4 on connectors A
and B. As before, these are duplicated on connectors C and D. Assignment
and set-up can be specified in the software configuration file.

To add channel logos to a panel, first the logo graphics must be made. The
size is fixed as an automatic resize would lower the image quality. Each
channel logo must be a 148x50 pixels 24 bit colour .bmp The .bmp must be
the standard windows type, uncompressed (not RLE compressed).

The logo files must be given a filename that matches the name used in the
panel.conf file and placed in the following directory: /mnt/i565cache/logos/
(If the logos part of the directory does not exist, it must be created)

Here is an example of a 3 channel system with a logo for each channel, as
displayed in the dialogue example. First three files are created:

GardenTV.bmp
ZooTV.bmp
DinoChan.bmp
Then the panel.conf (on the panel or PresStation) is edited as follows:

The groups of channels can also be given na m e s, in the example dialog
displayed above, groups 1-10 is called Sports, 11-29 News, 21-30 Childrens
and 31-40 is called Evening.

The PresStation audio meters work in the range from 0 (full volume) to –138
(infinitely quite) decibels i.e. Full Scale Deflection and adjustment can be
made within these limits to set the following:

♦ Upper decibel limit (dBFS Top)
♦ Lower decibel limit (dBFS Bot)
♦ Upper text limit (Text Top)
♦ Red threshold (Red Div)

Setting dbfs top=0 and dbfs bot = -25 will give a range of 25 dbfs, if we set
Text Top = 10, then the labelling on the meters will start at 10, go through 0

to -15 (25 dbfs range). Red Div is where the meters change from green to
red, not in dBFS, but as text for ease of use (normally set at zero). If it was in
dBFS you would have to set the value TextTop – dBFS Top, in order to get
the red position at zero label.
