8 The IP Manager

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.

10 Recording

With the K2 Edge Recording option you can record a Live input and ingest as an Asset. Following file types can be recorded: AVF, MPG, MXF.
What is needed:
A default Recording Channel is preconfigured in Cobalt Asset Manager: Record 1. To enable,
you need a License per K2 Edge.
You need the RecPack Channel pack to work with the Recording function. The RecPack
Channel must be activated on the Recording Channel.
How to:
Enable recording on the playout server via the IP Manager > Channel configuration >
Enable recording channel: select On.
Create a (temporary) Playlist on the Recording Channel. This Playlist is used to schedule
Events with the LiveRecord Format attached.
In TX/MAM, create an empty Asset of the appropriate Asset Type.
You can also overwrite an existing Asset. In that case, make sure that in the LiveRecord
Format the Overwrite option is set to 1.
Drag the Asset into the (temporary) Record Playlist to schedule an Event.
Attach the LiveRecord Format to the Event and edit applicable settings:
You only have to specify Event Duration. You do not have to specify an Event Tc in / Tc out.
K2 Edge User Manual - document version: 4.0 – Page 14
: Pre-check OK (If not, the icon turns grey).
: Recording OK.
: Recording error.
: Ingest successfully finished.
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.
Default duration + 5 seconds from start.
Ingest Recording: start ingest, default duration + 5 seconds from end.
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.
The Flag column shows following status indicators:

11 Configuring time settings

Preferably a LTC-signal (Linear Timecode) is used to synchronize time codes. If this is not possible, other options are:
NTP sync (Network Time Protocol) to a NTP- server.
Free running (system uses an internal clock)
Setting up NTP:
Edit /system/objects/code/setdate
NTPSERVER: specify the NTP-server's IP-address
ZONE: specify time zone [see options below], the ZONE-setting determines offset relative to
CET/GMT.
To test settings, from Linux command line enter: /system/objects/code]# setdate -ntp [enter]
If settings are incorrect, an error message will be displayed.
To ensure that time is regularly synced, edit /etc/crontab. Remove the "#" in front of the line:
#00 * * * * root /system/objects/code/setdate -ntp >/dev/null 2>&1
Result:
00 * * * * root /system/objects/code/setdate -ntp >/dev/null 2>&1
K2 Edge User Manual - document version: 4.0 – Page 17
47 = seconds
Configuring time manually:
To set the date, log in via putty (ssh) as user root.
Go to the /system/objects/code folder:
...code]# cd /system/objects/code [enter]
Execute script setdate, use the –help option for an explanation:
...code]# ./setdate –help [enter]
Example:
...code]# ./setdate -m 07/29/08 11:37:47 [enter]
Explanation:
-m = manual
07 = month
29 = day of month
08 = year
11 = hours
37 = minutes
Requesting the NTP date and time:
To request the date from the NTP server configured in setdate:
...code]# ./setdate -ntp [enter]
ZONE options are listed on the next pages.
Notes:
Options listed below are case sensitive.
Insert a “/” sign behind continent names.
Place ZONE names between quotes.
Example: “Europe/Amsterdam”

13 K2 Edge IOs

13.1 Tiles

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.
K2 Edge User Manual - document version: 4.0 – Page 23
14 Supported input/output broadcast format
combinations
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:
PAL -> 1080@50i
1080@50i -> PAL
NTSC -> 1080@59.94i
1080@59.94i -> NTSC

16 Appendix: Changing an IP-address

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.
