2 About this document
This document applies to the K2 Edge release 4.0.
The K2 Edge Smart Playout Center Commissioning Manual describes how to commission a
Channel.
De K2 Edge contains 8 bidirectional SDI-ports. A number of presets have been defined for the K2
Edge. These presets can be selected via the IP Manager.
Possible Channel configurations on a single K2 Edge server:
• Single Channel HD
• Single Channel SD
• Single Channel HD + Preview Channel
• Single Channel SD + Preview Channel
• Simulcast
Note that available options depend on licenses purchased.

o Channel Single Outputs: IO2(HD),IO4(HD),IO7(HD),IO8(HD)
The IP Manager enables remote server management, monitoring and configuration. The IP Manager
is accessible via web, or via the LCD-panel on the front of the server. Two menus are available:
• the K2 Edge-menu: standard menu
• the IP Manager menu: also available when the system is unreachable (note that this menu
has less options)
If the system is unreachable, press the knob for 3 seconds to switch from the K2 Edge menu to the IP
Manager menu.
8.1 Starting the IP Manager web interface
To access the IP Manager, enter the IP Manager's IP-address in a web browser.
8.2 The LCD front panel
Use the rotary knob to operate the IP Manager via the front panel:
•Turn the rotary knob backwards and forwards to scroll through
options.
• Press the rotary knob to select an item or confirm a selection.
• Selected items are marked by [], <>, an arrow, or are highlighted.
• Press the knob 3 seconds to return to the main menu.
• Or, to discard changes and return to the main menu from a sub menu,
rotate the knob to the
•back/cancel/discard option, then press the knob.
Some changes in settings require a restart of the nexos processes to be activated. In that case, the
Activate button is available in the IP Manager. Click Set to save changes, and then Activate to
activate changes.
If the Activate button is not present, no restart is required. Click Set to save and activate changes.
Changing settings and executing commands via the IP Manager can interrupt a broadcast.
Example IP Manager menu. The system’s hostname is shown in the upper right corner and on the
web page’s tab. The highlighted menu item shows where you are in the navigation tree.

• UDP Monitoring: use this option to monitor Channel 0 (the single HD or SD Channel, or the HD
Channel in a simulcast setup) via IP. When enabled, a MPEG- transport stream with encoded
video, graphics, subtitles and audio (first stereo track) is sent over Ethernet using the UDPprotocol. A video player such as VLC is installed on a workstation to view output.
The UDP-monitoring option is described in more detail in the K2 Edge User Manual.
Use this option to monitor Channel 0 (the single HD or SD Channel, or the HD Channel in a simulcast
setup) via IP. When enabled, a MPEG- transport stream with encoded video, graphics, subtitles and
audio (first stereo track) is sent over Ethernet using the UDP-protocol. A video player such as VLC is
installed on a workstation to view output.
You need a license to enable the monitoring functionality.
Enable monitoring via the IP Manager > System monitoring > UDP Monitoring > Ethernet
Output: select On.
Settings:
• Resolution: 320x240/ 240x180/ 160x120
• Aspect Ratio: 4:3/ 16:9
• Video Bitrate: in kbit/s
• Audio Enabled: On/Off
• Audio Bitrate: in kbit/s
• Ethernet Output: select On to enable monitoring and start streaming, Off to disable.
• IP-address: IP-address of the target workstation (can be a multicast address)
• IP-port: port the player will listen to. Default 4000
To receive the stream at the client:
You can use a media player such as VLC (http://www.videolan.org/vlc/) on a local workstation to view
the video and audio content contained within the mpeg transport stream:
Start the VLC-player.
Choose Media > Open Network Stream.
Enter the network URL: udp://@:XXXX, where XXXX = the IP-port specified in the IP
Schedule a manual Event after the recording Event if you do not know the recording Event’s
duration in advance. When a manual Event is scheduled after the recording Event, recording
will be stopped when the manual Event is triggered. The recording Event’s duration is ignored.
Other time codes explained:
•StartLiveRec: sends the Start Live recording command to nexos, default 6 seconds
prior to start.
•Ingest Recording: starts ingest, this Applet is started when the next Event is a manual
Event. In that case duration is ignored and this Applet will stop recording.
Other parameters, Applets and Templates explained:
• Live: specifies the input port that is recorded
• pre asset: a check performed before recording starts. Verifies allowed file extensions,
Asset ID and contains the Overwrite option (0 is not allowed, 1 is allowed).
• ioInput: specifies the input port that is recorded
• format: broadcast format
• bitrate: bitrate
• audiopairs: number of pairs
• overwrite: 0 overwrite is not allowed, 1 is allowed
• vbirecord: 0 do not include vbi info, 1 include vbi inf
Note that you can modify these parameters for the Event in POC. We advise to change the
Format in Channel Composer if you want to work with different parameters than the ones
predefined.
Activate the Event(s) you want to record to the Record Channel, to the appropriate date and
time.
Make sure the LiveRec Channel Pack is activated on the Recording Channel.

De K2 Edge contains 8 bidirectional SDI-ports. One video format can be configured per tile.
IO1 is always configured as input and IO2 as output to be able to use the bypass relay. A
number of presets have been defined for the K2 Edge. These presets are selected via the IP
Manager.
IOs and tiles.
13.2 Bypass
Ports IO1 (input) and IO2 (output) can be internally connected to bypass a Channel. When set
to bypass, the signal of the main Channel is ignored, and instead the feed received at IO1 is
made available at IO2. Bypass is enabled via the IP Manager.
13.3 Master and Slaves
To make a Channel's signal available on several SDI-outputs, one or more of the IO-ports can
be configured to become slave outputs. By default, the signal provided by a slave output is an
exact copy of the master output signal. A slave output uses the properties of the master
Output it refers to, and thus cannot introduce another broadcast format for the same Channel.
13.4 Genlock
If enabled, the SDI-output synchronizes to the frame rhythm of the genlock (blackburst) signal
connected to the blackburst BNC-socket on the back of the server. If disabled, or when no
genlock signal can be detected, the output will synchronize to an internal clock. Genlock can
only be set for master outputs.
IO-ports can be configured as SDI-inputs. The incoming signal can be made available to one
or more Channels, for example for coverage of live events. Inputs behave much like clips on
the K2Edge; they can be queued and started at any time. Inputs be can shared over multiple
Channels, and each Channel can handle several inputs simultaneously.
In Channel Composer, the Live Object is used to manage inputs.
At the moment there is no support for auto sensing the incoming signal’s format. The input
broadcast format does not have to be an exact match of the Channel/output format, but both
frame rate and interlaced/progressive mode must match.
Supported Input/Output broadcast format combinations are:
After changing the playout nodes’, TX/MAM or FTP-servers’ IP-address, following
adjustments need to be made:
After changing the IP-address of the playout nodes:
1. Change the IP-address in Cobalt Asset Manager Channel settings.
After changing the virtual IP-address of the TX/MAM-servers:
On standalone demo systems, the /system/txmam_fix_ip.sh script can be used.
1. On the K2Edge nodes, in /etc/hosts adjust MAIN-DB. Specify the virtual IP of the
TX/MAM servers.
Example:
You can also set the IP-address of the TX/MAM server via the IP Manager.
2. On both the TX/MAM servers, in /usr/local/apache2/application/configs/application.ini,
adjust project_options.serverip. Specify the virtual IP of the TX/MAM
servers.
Example:
3. On both the TX/MAM servers, in usr/local/apache2/application/configs/ingest.ini,
adjust ingest.assetHostIp. Specify the virtual IP of the TX/MAM servers.
Example:
After changing the IP-address of the FTP-server:
1. On both the TX/MAM servers, in /usr/local/apache2/application/configs/videoftp.ini,
adjust:
• videoFtp.host to the FTP-server IP
• videoFtp.user to FTP-server user
• videoFtp.password to FTP-server password
• videoFtp.path to FTP-server path
2. On the TX/MAM server (main and backup) in
/system/objects/cobassets/bin/transfer_ftp.xml, adjust the transfer metadata.
Transfer metadata can be set with the /system/objects/cobassets/bin/set.sh script.
