1.0 What is Skype TX Client?
Skype TX enables you to send Skype calls as HD/SD-SDI video with embedded or
balanced analogue audio, providing the best call quality available in an HD video
format.
Skype TX optimizes the call quality and resizes and adjusts the video content to
conform to standard television video resolutions. It even monitors the call,
automatically drops the video feed of the call (but not the audio), and switches to a still
image of the video feed if the call drops below a quality level that you define.
You can use Skype TX to prevent the video from reframing when Skype changes the
aspect ratio. You can also embed the Skype watermark in the video output without
using a separate graphics system.
Skype TX features include:

Make outgoing calls
Make HD-quality, broadcast-ready calls.
8

Receive incoming calls
Assign an incoming call to any connected Skype TX channel.

Monitor call quality
See technical information about the call to help troubleshoot local or remote
network issues.

Manage calls
Switch between a live video feed and a still image.
Note that Skype TX is limited by the available connection speed and infrastructure,
which can affect the quality of your calls.
9
2.0 What is Skype TX?
Skype TX is a management solution for controlling multiple Skype TX units. Using this
software, it is possible to manage multiple Skype TX Channels and call any contact in
your Skype address book on up to 14 connected Skype TX units.
Skype TX simplifies the workflow for getting contributors on air. You can search, add
and call a contact on any of your connected Skype TX units by using familiar Skype
features that are in all Skype clients, but still within the broadcast tailored Skype TX
interface.
Skype TX Control features include:

Mini previews
Monitor and compare all of your live calls side by side straight from the user
interface.

Manage calls
Take a snapshot from the incoming video and manually switch to the snapshot
as required.
10

Multiple running copies of Skype TX on different machines
To help your workflow, you can use Skype TX to control multiple Skype TX units
simultaneously and store your configured connections for different users by
using different Skype accounts

Skype Search
Search the Skype directory for any of the connected users using their name,
Skype name or email address.

Send contact requests
Send Skype Users a contact request and add them into a shared contact
database ready to place a call on any one of your units connected on the same
local network.

Contact status

only shared across multiple controllers, but can also be accessed and edited on
other Skype software such as Skype for Desktop.

Monitor calls
Monitor network and call quality at a glance, receive indication of audio signals
and a handy indicator that shows who is talking at any one time, as well as in
depth call technical information on each call.
11
3.0 System Requirements
Skype TX requires a connected Skype TX unit from a hardware partner in order to use
the full feature set.

Skype TX runs on a Windows 7, 8 and 8.1 based systems.

Your system must be capable of running the operating software in order to run
Skype TX.

Requires at least 50MB of storage space.

Skype TX is primarily designed to be operated with mouse and keyboard. Most
key features have, however, also been optimized for touch screen use'

High speed Internet access required. Connect time charges apply. Note that
Skype TX is limited by the available connection speed and infrastructure, which
can affect the quality of your calls.

Microsoft Account or Skype Name required.
12
4.0 Getting Started
A typical multi-channel system would have one or more Skype TX units running the
latest version of Skype TX client and a computer running Skype TX. The minimum
requirement for Skype TX Control to work with a Skype TX Channel is that it must be
able to connect to TCP port 8000. This makes it possible to have Skype TX units on a
different subnet and/or behind a firewall which can allow you, for example, to apply
less-restrictive internet access policies to Skype TX machines (potentially improving call
quality) whilst keeping Skype TX Control within a more strictly-controlled network. This
will enable Skype TX Control to manage the Skype TX units on the network. Consult
your network administrator, IT manager, or Internet provider for questions about your
network.
In the examples in this guide, there are four Skype TX units under the control of Skype
TX.
“Skype TX Client” refers to the software on the Skype TX unit. This is what is used to
generate the Skype video as an SD/HD-SDI video signal for on air.
“Skype TX” refers to the controller software used in conjunction with Skype TX to
manage the channels.
13
4.1 User interface
Skype TX features a clear user interface with easy to use user controls for managing
multiple calls.
1. Signed in account information – This shows the signed in account.
2. Contacts address book and search window – This panel lists the Skype
Contacts of the signed in user along with indicators showing their connection
status, a call button to call on any available connected channel and a search box
to search your own contacts as well as the Skype Directory. For more
information, see 4.3.3 Adding someone to your contact list.
14
3. Channels – Each strip shows a channel added by the user, along with the status
of connected calls, video previews, call controls and settings. Each strip is
divided in two. The top half shows the current call and indicators to monitor the
call at a glance. The bottom half shows additional information about the call,
snapshot and channel settings.

17
4.2 Signing in
This version of Skype TX introduces signing in with a Skype Name or Microsoft
Account. This sign-in information will then replicate through all connected Skype TX
units. There is a maximum of 14 connected units that can be signed in with the same
account.
When you first startup you will see the following:
If you want to use a Skype Name to sign into Skype TX, then select Skype Name.
18
If you want to use a Microsoft account to sign into Skype TX, then select Microsoft
account. At the bottom right of the window, there is a check box with the option to
sign into Skype TX automatically on launch. Check this for Skype TX to sign in
automatically on startup.
Once you have signed-in you will see the client home with no connected channels. You
will need to add your connected Skype TX units to start using Skype TX, see 4.4 Adding
machines for more information. The sign in details appear in the top left of the user
interface.
19
4.3 Contacts
As you are using a Skype Name / Microsoft account to sign in, you can now get access
to Skype Contacts from the signed in account’s Skype address book. These contacts are
loaded as soon as the software starts which can take a few seconds if you have a large
number of contacts. The list shows the display name and the real-time online status of
each of your contacts. Skype TX only shows the contacts that you can contact using
Skype TX, so by default it filters out blocked contacts, removed contacts, Facebook
contacts, phone numbers, Skype for Business contacts or contacts without a valid user
name.
20
4.3.1 Status
The Skype status of a contact is now shown in Skype TX. Status will change when the
contact connects to Skype or manually changes their status. Skype TX shows these
changes dynamically so you can see exactly when a contact comes online, goes offline
or is busy. Below is a breakdown of all the Skype status’ you will see in Skype TX:
Online
The contact is online and available.
Away
The contact is away from their computer or device and may be inactive.
Do not disturb
The contact is busy and does not wish to be disturbed. They won’t be notified of
an incoming call.
21
Invisible / Offline
The contact is either invisible or offline. They can still receive a call if invisible.
Pending
The contact is yet to accept the contact request or has missed it.
4.3.2 Favorites
When you first sign in to Skype TX and load your contacts, by default you will have no
favorite contacts. When signing in with a Skype Name, Skype TX won’t synchronize
your Skype favorites from another Skype client, so you have to add them manually.
However, if you sign in with a Microsoft account, Skype TX will automatically display
your favorites in the Favorites section and will persist any changes made to favorites
across all Skype clients. If you don’t have any favorites, this behavior won’t be
exhibited. Once your favorites have been displayed, or once you have added a contact
as a favorite, a group appears at the top of the contacts list, called Favorites. The
contact is then moved from the All Contacts group, to the Favorites group. Each
group can be collapsed by choosing the up arrow at the side of each group:
To make a contact a favorite:
1. Choose the star outline next to a contact
Or
2. Choose the avatar of the chosen contact. This opens the Edit Contact panel
where you will see the outline of a star. Choose this to mark the contact as a
favorite.
22
To remove a contact as a favorite, choose the filled star. This will return the star to an
outline, and return the contact to the All Contacts list. If you remove the last contact
from the favorite group, Favorites will fade off and the All Contacts list will return to
filling the whole contacts list.
23
4.3.3 Adding someone to your contact
list
With Skype TX, you can now add someone to your contact list, all from within the
single user interface, by searching for the contact and sending them a contact request.
You can easily search the Skype directory for any of the 300 million plus connected
users and send them a contact request to add to your contact list.
The first step to adding someone to your contact list is to search for them.
1. Navigate to the search box at the top of the contacts list.
2. Search for the person you want to add using their email address, Skype Name,
Microsoft Account or name (also often their display name).
3. Choose Search Skype for button after you’ve typed in the contact info you
want to search by.
4. Profiles matching your search info will be listed under the search box. If the
search term is an exact match for a Skype Name or Microsoft account, that will
be listed first. The remaining search results will then be listed by matching
display name, then by next closest to display name and Skype Name or
Microsoft account. Choose the add button
next to the contact you want
to add.
24
5. This will open up the Send Contact Request panel.
Here you will see the Skype Name or Microsoft account of the chosen contact
for confirmation that you have chosen the right person, as well as a message
box.
6. Enter in an appropriate message for your new contact so that they know the
right person is contacting them. They will see the accounts display name as
determined by you when creating the account or when editing it in another
Skype client.
25
In the event you chose the wrong person to add as a contact, you can always
return to your search results by choosing the back button
.
7. Choose Send Request to send the contact request.
Your contact is now added to your contact list, but you’ll only see the
Pending
Skype status until they accept your request. When your new contact accepts your
request, you can see when they are online.
If you have a large contacts list and can’t find your newly added contact, you can
always search for their Skype Name or Microsoft account, or display name and Skype
TX will perform a local search before you choose to search the Skype directory.
4.3.4 Contact details
Skype TX is designed so that you only see callable contacts. Facebook contacts,
blocked contacts, Skype for Business contacts and phone numbers will not appear in
the contacts list. Only contacts with a valid Skype Name or Microsoft Account will be
listed.
26
In Skype TX, you can change the contact details for each contact in the Edit Contact
panel, accessed by choosing the avatar symbol to the left of the contact.
In the Edit Contact panel, you can change/add the following:

Display Name
By default, this will be the display name as defined by the contact. If this has not
been changed since the account was created, then the first name and last name,
as defined by the contact, will be shown.

Designation / Location
When adding a new contact or when first signing in to Skype TX , this field will
be blank. This field can be used as a ‘second line’ of information that can be
used to show the contact’s location, designation, title or anything else that
might be of use. When changed, the information will be displayed as below:
27

Notes
This field is a general notes field that can be used to store information against
the contact for the future.

Favorite
You can also toggle the contact as a favorite or not in the Edit Contact panel by
choosing the star outline next to the contact Skype Name / Microsoft account.
When returning to the contacts list, you will see the contact in the Favorites
group.
At any time you can choose the back button and the changes will be cancelled. To
confirm the changes, choose the
tick button. If you mouse over the contact, you
will see the notes added to that contact.
The information added to a contact will also be seen in other Skype Clients as this
information roams with the contact. It can be seen in the contact profile of the contact.
This can be accessed by right-clicking on the contact and choosing View Profile, on the
Skype desktop client. This means that the changes you make in Skype TX to a contact,
will also be seen on the desktop Skype Client, as well as all mobile devices, to name a
few. The information will be displayed as below:
28
Each field is separated by the lozenge character ◊ (U+25CA in Windows Character
Map). Everything before the first lozenge is the Display Name. Between the first and
second lozenge is the Designation / Location. And everything after the second
lozenge is the Notes. Using this lozenge, you can add and edit contacts in another
Skype client and the information you add will be displayed in Skype TX.
To do this, right-click on the contact and choose View Profile. A box will pop up
showing the profile details for the chosen contact. Choose the display name of the
contact, and type in the contact information in the following format:
Display Name◊Designation / Location◊Notes
Here is an example:
Carlo Lorenzo◊Rome◊HD Webcam, 720p. Bad light after 17:00.
4.3.5 Remove a contact
Skype TX provides you with the flexibility to add, edit and remove contacts so that you
can change your contacts list as and when you need. Some contacts might only ever be
called once or twice, so being able to remove these contacts from your contacts list is
critical to keeping a manageable address book.
To remove a contact from your contacts list:
1. Select a contact to remove. That contact will be highlighted and a bar will
appear at the bottom of the contacts panel showing the number of contacts
selected, a cancel selection cross button and a
SHIFT keys to select multiple contacts.
action button. Use CTRL and
29
2. Choose the
button, a pop up box will appear where you will be able to
remove the contact from the contacts list.
3. Choose the remove button. The contact will now be removed from the contacts
list.
Removing a contact in Skype TX removes the contact from the signed in Skype Name
or Microsoft account address book. The contact will no longer be accessible for the
signed in account. You will have to add the contact again for them to return to your
contacts list.
30
4.4 Adding machines
To use Skype TX , you’re going to need Skype TX units running the latest client
software. On initial startup, the Channel area will be empty. Here is where added
channels will appear.
Before adding machines, it is best practice to make sure the target machines are
running Skype TX Client, this means that the machines will appear in Skype TX
controller when added, providing a clear indication as to whether Skype TX has been
able to establish a connection with the target Skype TX Client.
To add a machine:
1. First navigate to the
Menu and if note already open, expand the menu by
choosing it.
2. Choose the Add a Skype TX Unit to control box and type in the target
machine name, found in PC Info in Windows, or IP address.
3. Choose the
plus button to the right of the entry box. The new channel will
now appear in the Channel area.
31
Skype TX will now attempt to connect to the target machine. In order to do so, the
Skype TX unit must be on the same network as Skype TX and be able to connect to TCP
port 8000. First Skype TX will search for the target machine:
If it cannot be found, Skype TX will show “Skype TX unit not found” with a retry button.
If the unit cannot be found, check that the target machine is online and connected to
the same network. If found, Skype TX will show the current state of the unit. The unit
can be in any of the follow states:
32
Channel not found
Channel Claimed
Channel in use
The Skype TX unit has
The Skype TX unit has

to in this state.
Unclaimed
The Skype TX unit has
not been claimed by
anyone and is ready
to be signed in.
33
It is possible to run Skype TX on different machines all connected to the same set of
machines. This is why Skype TX shows the exact state of the unit and the channel it is
running, so that in the event there are multiple copies of Skype TX running, each
operator can see who is using each unit. In the event you wish to connect to the target
Skype TX unit, and it is signed in as another user, choose the Sign out button. You will
see a warning asking you to make sure you want to sign this user out before signing in
with your Skype Name / Microsoft account. Choosing the
back to the channel status. Choosing the
red cross will take you
green tick will sign the channel out. This
will put the channel into Unclaimed status, ready to be claimed and signed in.
In the event an error occurs and the connection between Skype TX and the unit is lost,
the channel state will change to Error. Choose the Retry button to attempt a
reconnection.
Remove a channel:
1. Navigate to the chosen channel and select the drop-down at the channel
number.
2. Choose Remove channel. The channel will no longer be in the Channels area.
4.5 Channel settings
Skype TX features the ability to change most of the settings of the connected Skype TX
units. The settings exposed are the ‘operational’ settings that don’t require a software
restart. Settings are per channel and are accessed by choosing the
Settings tab
in the bottom panel.
34
4.5.1 Video Output
Here is where you can define the behavior of the connected units' video output as sent
to the studio facility. To change the video devices, use the Skype TX Client software. For
more information on how to do this, see hardware partner supporting documentation.


set as the default with ‘logo’ and ‘clock’ both checked. The user can change
between:
o
Testcard – Shows broadcast color bars with the channel
identification and the current time of day. Note the clock shows the time of
the local computer. This is not a synchronized external time code.
o
Still – Any image can be used to act as a channel identifier or holding
page for the user’s channel. The system uses the PNG image named
‘NoCall’ located in the following folder on the target Skype TX unit:
‘%USERPROFILE%\Pictures\Skype TX\Client’. This can be overwritten with a
different image if required.
o
4.5.2
Black
Audio
This drop-down features the audio controls for the connected Skype TX unit. To
change the audio devices, use the Skype TX Client software. For more information on
how to do this, see hardware partner supporting documentation. Note that changes
made during a call will not take effect until a new call is placed.


General Audio – Global audio settings that aren’t restricted to the input and
output.
o Disable all Skype audio processing – If checked, this will disable all
audio processing, which includes automatic gain control, echo
cancellation and noise suppression. This will auto-hide all other settings
in the audio section and a notice will appear to confirm this. Uncheck to
gain access to all other settings in the audio section.
o Disable Analog AGC – Disables just the analog automatic gain control.

Audio Input – The input audio is the audio coming in to Skype TX from a local
source, which is sent over Skype to the remote caller.
o Disable AGC – Disables Automatic Gain Control (AGC) on audio being
sent to the remote caller. You might want to disable AGC if the audio
being supplied to the Skype TX unit is of a consistent level already.
Doing so may help manage feedback issues.
o Disable Noise Suppressor – Disables the Skype feature that lowers the
audio level being sent to the remote caller when it detects only
background noise.
37
o Disable AEC – – Disables Automatic Echo Cancellation, or AEC. AEC
helps prevent audio from the remote caller being sent back by way of the
local microphone.
4.5.3
Account
Skype TX features the ability to change most of the settings of the connected Skype TX
units. The settings exposed are the ‘operational’ settings that don’t require a software
restart.

Unit Identifier – Text that is shown in the client window and test card. This
helps distinguish your channel from others that might be running. It’s shown
When not on a call on the video output and is used to help identify the
machines.

Network – Skype network connectivity setting.
o Port to use for Skype – Values higher than zero will cause Skype TX to
try this port number first each time you sign in. If this fails, or the value is
zero a valid number will be chosen automatically.

5.0 Making a call
It is important to understand that Skype TX doesn’t make the Skype calls. Skype TX
sends commands to the Skype TX units and reports back status updates. With Skype
Contacts in your signed in account and channel previews and status, it makes it
possible to control and manage each Skype TX channel from a single UI. Each Skype TX
channel can be set up and controlled by Skype TX.
To start with, make sure you have added all your connected Skype TX units and have
signed in to each channel using the single sign-in feature. In the following example,
there are four connected Skype TX units being controller by the Skype TX software.
5.1 Establishing a call
Skype TX connects directly to Skype TX unit. It tells the unit to make a call. To make a
call, Skype TX must go through several stages to establish a stable connection. Making
a call relies on the remote caller being a contact of the signed in account. To add
someone to your contact list, see 4.3.3 Adding someone to your contact list.
Once added, the contact will appear as a pending contact until the contact request has
been accepted by the target contact. To accept a contact request on Skype Desktop
Client:
1. Above your contact list, choose Recent. The number inside the orange circle
represents how many contact requests or instant messages you have pending.
The message from the person with a question mark as a status icon is the
pending contact request.
2. To accept or decline the contact request, enter the chat window by choosing
the contact's name.
3. To accept the contact request, choose Accept. The contact is added to your
contact list, and you can see their online status and make video calls with them.
39
In the event the remote caller does not want to add you their Skype Contact list, you
can send a contact request and call them in their pending state, as long as the contact
has set their privacy settings to allow calls from anyone. To do this in Windows:
1. Open Skype on the remote caller’s computer.
2. Sign in to Skype.
3. Go to the Tools tab and left-click Options.
4. Go to the Privacy section and set Allow calls from… to Anyone.
5. Left-click Save and return to Skype. The remote caller is now set up to be called
from Skype TX.
To do this on a Mac:
1. Open Skype on the remote caller’s computer.
2. Sign in to Skype.
3. From the menu bar, left click Skype then navigate to Preferences.
4. Now go to Privacy and select Anyone from the Allow calls from: drop-down
box.
5. Close the Privacy window.
For more information or support on Skype, visit support.skype.com.
In the event you do not wish to add the contact to your signed in contact address
book, you can use the input box on the channel.
40
Simply type in the Skype Name or Microsoft Account of the remote caller and choose
the
video button to start a call. As the remote caller has not been added as a
contact, they will have to change their privacy settings for the call to go through.
Either way, the contact should now be ready to receive your call. To call the contact:
1. Navigate to the Contacts address book and search window and find the
contact you wish to call. Or, alternatively, simply type the Skype Name or
Microsoft account of the remote caller into the input box on the target channel.
If calling an Microsoft account, type live: before the ID and skip on to step 4.
2. Choose the
camera symbol to the right of the contact. This will open the
Call Contact panel.
41
3. Choose an available connected channel to call the contact on by choosing the
name or number of the channel. Each channel can be in any of the following
states:

Ready for use

Busy – in a call

Claimed by another user

Claimed and in a call

Unclaimed

Unit not found

Skype TX not found on unit

Signing in

Signing out

Error
At the top of the target channel, you will also see that the channel is Ready.
42
4. Skype TX will now try to initialize. First the call will show Establishing Call. This
is the Skype TX unit trying to establish the call between the signed in account
and the remote caller account. Once the call has been established, the call status
will show Ringing at the far end. This shows that the contact is now being
called and you are waiting for them to answer the call. If the call is declined by
the user, the call status will show User declined call. Once the call is answered,
the call will be connected.
5. Skype will first connect the audio, as represented by the small orange audio
indicators on the video output preview and next to the return video preview.
The bar at the bottom also show if audio is presence from the remote caller.
43
Once the audio is connected, the video will connect, which you will be able to
see in the preview windows. You can see the raw incoming Skype video by
hovering over the video output and holding down the left mouse button. If the
video output fails to connect, the output will show the default fallback image or
the user defined fallback still.
The small video symbol under the return video preview will change from a red
camera with a line through it, to a solid green camera once the return video has
connected.
The call is completely connected once the video indicators have turned green
and the audio indicators are jumping up and down.
44
5.2 Taking a snapshot
Skype TX can be used to take a snapshot of the remote caller. You can use this
snapshot as a backup image if the call quality drops below the video resolution you
have defined. You can also use the snapshot if the video feed from the remote caller
drops entirely, leaving a snapshot and the remote caller’s audio feed.
Taking a snapshot takes a still of the remote caller in whatever state they are currently
in. You can then preview the snapshot for the call by accessing the snapshot lower
panel. But first, to take a snapshot of a remote caller:
1. Navigate to the Channel you wish to take a snapshot on.
2. Make sure the call is live and connected.
3. Choose the
snapshot button in the top panel just below the video output
preview. This takes a snapshot of the remote caller in their current state.
Alternatively, you can access the snapshot panel in the lower half of the
Channel strip by choosing the
snapshot tab where you can see a preview
of the snapshot and a snapshot button. You can also use this button to take a
snapshot of the remote caller.
Before a snapshot is taken, Skype TX will show the fallback image in the snapshot
preview. As a default, the following image is used if the remote caller’s video feed is
lost or falls below the user-defined minimum video resolution. This image also appears
when initiating a call.
45
This image can be overridden by the user by placing a PNG graphic named ‘VideoLost’,
on the connected Skype TX unit in: ‘%USERPROFILE%\Pictures\ Skype TX\Client’. When
taking a snapshot, this image is replaced with a snapshot from the current call. At the
end of the call, the snapshot is reset and the user defined fallback image or default
image will be shown.
Note that once you add a snapshot of the current caller, you cannot go back to the
fallback image in the same call.
5.3 Managing a call
Skype TX units have the ability to revert to a previously configured state if video is lost
or has unacceptable video resolution. It can switch between live video from the remote
caller, a pre-grabbed still image, or a pre-defined image. See hardware manufacturer
documentation on how your Skype TX units can be set up to manage calls.
Skype TX can manage a call in the same way you can on a Skype TX unit. On each
channel, in the snapshot tab in the lower half of the channel, you can change the
Auto-Fallback Mode between the following:
Always send caller video to air
When selected, the caller’s video will be broadcast, regardless of the
video resolution.
Send caller video to air, automatically switching back to snapshot
or VideoLost.png when its quality falls below quality threshold
When selected, if the caller’s video falls below the minimum video
resolution that you defined, the video will switch to a snapshot or the
VideoLost.png.
46
When selected, if the caller‘s video falls below the minimum video
resolution that you defined, the icon turns partially red.
Send snapshot to air
When selected, the snapshot that you have taken appears, replacing the
caller’s video.
To send a snapshot to air:
1. Choose the
snapshot button on the desired channel during the live call.
Make sure that the remote caller is in the preferred position before taking the
snapshot.
2. Select the
Send snapshot to air button in the snapshot tab, to send the
snapshot to air.
This sends the pre-grabbed snapshot of the remote caller to the video output.
Note that the snapshot is only available on the channel the snapshot was taken. It isn’t
available on all other channels and must be retaken if the call ends.
The snapshot panel is also where you can define the Minimum Resolution when using
the automatic fallback feature. If the incoming video resolution fails to meet this
resolution, the drop down box will show a red outline.
47
When the video meets or exceeds the resolution, the outline will turn green. Supported
resolutions are:

1920 × 1080 (16:9)

1280 × 720 (16:9)

640 × 480 (4:3)

640 × 360 (16:9)

320 × 240 (4:3)

320 × 180 (16:9)

160 × 120 (4:3)
You can also manage the call by refreshing the channel to check that the call
information and previews are live. You can do this by choosing the Refresh button on
the selected channel, as below.
48
5.4 Monitoring a call
Skype TX is able to monitor multiple calls as they are on air. You can use the quick
previews built into the each Channel to check that audio and video are being sent to
the remote caller, and that audio and video are being received by the connected Skype
TX unit.

For a more detailed breakdown of the call, you can use the Call Quality Information
bottom tab. Choose the
button to access this tab.
50
This panel is separated between the Incoming and the Outgoing. The incoming is
information related to the remote caller and the outgoing is information related to the
local outgoing.

quality.
51
Relay UDP - then this means that direct UDP connection is not possible
and this, as a rule, will result in significant degradation of Skype
connection.
Relay TCP - then this means that direct TCP connection is not possible
and this, as a rule, will result in significant degradation of Skype
connection.
o Packet Loss – Percentage of network packets being lost in the incoming
streams. Lower is better

For more technical breakdown of the call please see the Skype TX User Guide.
5.5 Incoming calls
In addition to making calls, Skype TX can be configured to receive incoming calls. This
means that remote callers can call directly into Skype TX.
53
To receive calls:
1. Choose the Incoming calls tab
at the tocp of the Contacts address
book and search window panel.
2. Choose to either allow calls from anyone, or from contacts only.
Incoming calls are now enabled. Choosing to allow calls from contacts only
means that only contacts that are in the signed in accounts Skype address book
will be able to call into this account.
When receiving a call, the remote callers will appear in the Incoming calls panel with
the number of callers appearing on the Incoming calls tab.
Note that closing down Skype TX will result in loss of incoming calls. If you wish to
preserve the calls coming into the signed in account, sign out before closing and re-open
the software.
Choose the Answer button
and the Answer call panel will appear where you can
choose an available channel to answer the call on.
54
Choose the Decline button
and the incoming call will be rejected.
Note that once the incoming call settings have been chosen on Skype TX controller, it is
recommended to not change the same settings in Skype TX Client.
5.6 Ending a call
When you are ready to end the call, either you or the remote caller can hang up to end
the Skype call.
To end a call in Skype TX , you can either:
1. Navigate to the desired Channel and choose the
hang up button.
Or
2. Navigate to the Contacts address book and search window. Each contact
that is on a call with display
a hang up button with the number of the
channel they are being called on. Choose this button to end the call.

6.0 FAQ
If you experience any problems with Skype TX, check this list of Frequently Asked
Questions first. For further support, see www.skypeinmedia.com.
Q Why can’t I sign in to Skype TX?
A First, check that you are connected to the Internet by navigating to Internet
Explorer and attempt to connect to www.bing.com. If an Internet connection is
present, next check the username and password you used to sign in to Skype
TX to see if they are correct. If they are, try a different username and password.
If you are still unable to sign in to Skype TX, contact us for further assistance at
www.skypeinmedia.com.
Q Why isn’t the camera showing on the remote caller’s MacBook?
A When using a computer running the Mac OS, the camera is often used by
another application such as FaceTime or Photo Booth in the background. Only
one application can use the camera at a time. Get the remote caller to close all
applications, including Skype. Then get them to reopen Skype and try the call
again.
Q Why is it that when I try to call a contact, Skype TX immediately hangs up?
A This is most likely due to entering an incorrect Skype Name for the contact.
Check the Skype Name of the remote caller and try to make the call again.
Q Why am I not seeing the video in preview in Skype TX?
A The local video input feed won’t show until Skype TX has been signed in. If you
are seeing black, then the video feed could be in the wrong format or has not
been turned on. Make sure the video input format used is on the list of
accepted inputs.
Q I can see a video output preview but why can’t the broadcast facility see it?
A This could be because the Video Out settings haven’t been set correctly for
the broadcast. Check what video format is required and set it as such in Skype
TX under Video Out in Video Settings. If the broadcast facility still can’t see
the video out feed, then check that all cables are connected. If the problem
persists, contact your hardware partner.
56
Q Remote caller can’t hear studio.
A First ask the remote caller if they have their speakers turned on. If they do,
check that you can see outgoing audio levels bouncing next to the local video
preview. If audio levels are bouncing, then the remote caller needs to check
their Skype settings by going to: Tools, Options, Audio Settings, Speakers, and
checking that audio output is being shown.
Q Remote caller can’t see studio
A Once the call has been accepted, a second dialogue box pops up, asking the
user to accept the incoming video signal that is being sent by Skype TX.
Clicking Accept allows the video being sent from Skype TX to be seen by the
remote caller.
Q Studio can’t see remote caller
A Ask the remote caller to check whether they answered the call by clicking
Answer rather than Answer with Video. Clicking on the camera icon in the
centre at the bottom of the screen will show the camera. If the video continues
to not show, check the remote caller’s Skype video settings by going to Tools,
Options, Video Settings and make sure the desired video input device is
selected.
Q Studio can’t hear remote caller
A First check that you can see outgoing audio levels bouncing next to the local
video preview. If you can’t, open up the audio card control panel by opening
the hidden icons and finding the icon to access the control panel. When a
signal is being sent, the audio meters show green, bouncing levels. If you don’t
see this, then check that the audio settings in Skype TX are set appropriately
for your needs. If the problem persists, contact Skype TX.
Q The call keeps coming in as ‘Relay_UDP’, what can I do to stop that?
A This means Skype cannot establish a direct connection from end to end due to
routing or security settings on the network. On a corporate network, the IT
department might be able to configure their routers to improve the situation.
See the Skype IT Administrator’s Guide for more information:
http://download.skype.com/share/business/guides/skype-it-administratorsguide.pdf .
Q The remote caller received the call on their phone and not their computer.
What should I do to get the call to be received on their computer?
A Log out of all devices and log back in on just the computer.
57
Q Skype TX Client is still answering calls from accounts which I flagged in
Skype TX Control
A If you are using auto-answering functions in Skype TX Control, turn off autoanswer in Skype TX Client. These function independently, so enabling both
will result in Client and Control getting into a race for how to handle each
incoming call.
