•
From the Linux Administrator command line: Ping the local gateway IP address.
Example: ping 172.17.1.5 (use your appropriate local gateway IP address)
•

NOTES:
•
CRITICAL NOTE: The IP address of the EtherneTV-NXG server must be made as a
hostname entry in the DNS server in order for the server to be recognized by
desktop clients through its domain name (ie: http://vb.loc), rather than using the IP
address (ie: http://172.17.6.55).
•
For test purposes, the MIS Administrator can change the necessary DNS (host)
entry in the local PC hosts file. Modify the “hosts” file on the local PC to resolve the
EtherneTV-NXG IP address with
the actual hostname:
o
Search for the file named
“hosts” on the local PC c.
NOTE: If there is more
than one file named
“hosts” select the file
located in the
Windows/System or
Windows/system32
folder.
o
Modify the file by using
the right mouse button to
choose the “Open” or
“Open With” selection to
use Wordpad or Notepad to make the necessary entry highlighted in boldd.

Changing Time & Time Zone
When the EtherneTV-NXG is working in conjunction with the EtherneTV-MCS Media Control
Server, in order for the time to appear correctly, it is necessary to set the time zone to match
that of the EtherneTV-MCS server.
In order to manually change the time zone, follow the directions below to edit the
/etc/sysconfig/clock file and then make a new soft link to /etc/localtime.
1)From the Linux prompt, type "startx<cr>". This launches the Red Hat graphical user
interface.
2)Open a command line interface from the GUI
3)Type /etc/init.d/mediabase stop
4) At the lower right corner of the screen, right click on the "time" and select "Adjust Date &
Time"
5) From the pull-down menu, select the time zone you are in. For example,
"America/Detroit", then click "apply and "OK" to close the window. Adjust the time as
needed.
6) Return to the command line interface and type /etc/init.d/mediabase start
7) At the lower left corner of the screen, right click on the "Red Hat" icon and select "logout"
and click on the "Logout" button to return to the Linux prompt.

Important
Information
V
Brick's EtherneTV-NXG server has been integrated with the EtherneTV family of
products including the EtherneTV-MCS Media Control Server, MPEG-1/2/4
streaming encoders, Windows-based desktop computers (future Apple MAC
support for MPEG-4 only) and the EtherneTV-STB. The EtherneTV-NXG delivers
stored MPEG assets as unicast streams (with full VCR-like functionality such as
Stop/Pause/Play/FF/Rew) across an Ethernet network. The EtherneTV-NXG is built on a
DELL hardware platform. Other features include the ability to schedule asset playback,
asset searching, user and system statistics, plus much more. EtherneTV-MCS is required
to gain the full benefits of the EtherneTV-NXG server and is sold separately.
In order to set up the EtherneTV MCS server, please follow the directions in the EtherneTV
MCS Administrator’s Guide. Once the EtherneTV MCS server is setup and configured, then
end users can access video the EtherneTV-NXG server through the MCS web interface.
VBrick uses its own software-based components to decode streams on the desktop. There is
no client side software to install. The EtherneTV-MCS automatically downloads components
to the desktop PC upon the user’s initial access to the system.

Download Components
VBrick uses its own software-based
components to decode streams on the
desktop. These components include
decoders and filters necessary to view
MPEG-1, MPEG-2 and MPEG-4
streams on a PC using software
based decoding. The EtherneTVMCS automatically downloads these
components to the desktop with the
user’s permission.
If this is a new installation, it is
necessary to answer Yes to security
requests before components are
downloaded.

extension MUST end in .mpg for Mpeg1&2 and .mp4 for Mpeg4 files!!!!)
18. Select the correct encoding type (MPEG1, 2 or 4)
19. Click on Add
20. Next we will monitor the ingestion by clicking on Content>Video>Find/Modify

Automatic File Backup
The use of a dedicated drive 0 for the OS and VoD software benefits customers in two ways.
Firstly, OS patches or new VoD software updates only get applied to drive 0, leaving all the
content drives untouched. Secondly, both VoD servers use a mySQL database to index and
manage all video content and VoD configuration information. While this database is stored
on drive 0, each evening the system automatically backs up the database onto the RAID
drives. Should drive 0 fail, the database restore procedure uses this backup copy to rebuild
the database.
The Auto Backup feature is on by default and it is recommended that it be left on. However
if for some reason it is not required the following procedure should be used to turn this
feature off:
Note: If you get lost during editing hit “Esc” twice to leave edit mode. Hit “:” to return to
command mode.

Go to the NXG command line.
Type "crontab -e" at the command line; this puts you into an editor for the crontab
(the cron table). The editor is the "vi" editor.
Using the down arrow key, scroll down to the bottom of the file. A couple of lines up
from the bottom you will see two lines:

•
Cursor up to these lines and comment out this section by:
• Hit the "i" key to go into insert mode
• Type the "#" key in front of both these two line to comment them out
Hit <esc>, then ":" to go into command mode, then enter "wq" to save the changes and exit
the editor.
File Backup Cautions
Irrespective of the Auto Backup there are situations where the backup may not take place
soon enough after file ingestion. Therefore it is highly recommended that a separate copy of
the original content after ingestion be maintained for at least two days until the auto backups
are made.
License Key Re-Installation
The license is pre-installed on the server from the factory. You do not have to re-install this
license except for system restoration. Should you need to re-install the license, use the
following steps. A floppy disk is included that contains the license key for the EtherneTVNXG server. The key should be added to the /var/flexlm/license.dat file. If this file does not
exist then the file should be created in the specified path (/var/flexlm/). The following steps
will be used to make the floppy disk available to the Linux O/S:
From the root type: mkdir /floppy (enter)
Type: mount –t vfat /dev/fd0 /floppy (enter)
cd /floppy
You will now be able to copy the license file from the floppy to: /var/flexlm/license.dat
(NXG1) or /var/kasenna/license.dat (NXG2)

Operation Tips
C O P Y R I G H T
•
All assets that are installed into the server should have backup copies available in the
event of disk corruption. This will allow for an easy restoration of the system.
•
StreamPlayerPlus allows the recording of live streams to MPEG-1, MPEG-2 and MPEG4 files. Once saved the files can then be installed on the EtherneTV-NXG1 server for
playback. Make sure the “hinting” option is checked when recording MPEG-4 files.
•
When recording MPEG-4 and MPEG-2 files using StreamPlayer Plus software, it is
advisable to keep the length of the record to under 50 minutes to facilitate creating
playlists and keep viewing time manageable.
•
The controls for MPEG-4 Fast Forward and Rewind are not currently supported;
however, slide bars are supported and provide the same functonality.
•
As the disks become full the performance of head seek times diminishes and file
ingestion may fail.
•
Do not use spaces in filenames. Use underscores; ie: my_history_class.mp4.
•
Apple QuickTime 6.5, containing native MPEG-4 support, is the recommended MAC
desktop player for accessing MPEG-4 files from the EtherneTV VOD NXG. QuickTime
supports the Seek feature (accessed through a slider-bar) for MPEG-4 streams. Make
sure Edit >> Preferences >> QuickTime Preferences >> Streaming Transport option is
set to Automatically determine the best protocol and port ID or “use: UDP, RTSP Port ID
554”.
•
Samba is a widely used software package that allows Linux systems to connect to
Microsoft Windows networks and seamlessly share files with Windows host computers
and servers. This is the recommended method of ingesting files into the server’s
database. If you are connected to the Internet click
http://www.vbrick.com/support/downloads.asp , select Application Notes and then
“Samba Client Configuration”. There you will find detailed information regarding the
software package.
