to become mis-ordered, jumbling the video content. Using the Jitter Buffer in the QVidium decoder
or ARQ software can often restore correct packet order and stream integrity, at the cost of
additional delay. You can also avoid Dynamic Load Balancing by requesting MPLS (Multi-Protocol
Labeled Switching) service from your ISP.
1.7 Passwords and Security
The QVENC4K
™ requires a username and password to protect access to its configuration
settings. This includes both Web access and SSH access. The default user name for the web
interface
is “
admin
” and the
default password
is also initially set to "admin". Logging in as the
user
root
is not allowed. We strongly suggest that you change the password to keep your
QVENC4K secure, especially if it has direct access from the Internet.
Note on Resetting Password:
If you lose the password and need to reset it, you can go to
, click on
Reset Password
,
copy the “autorun” file onto a USB flash,
and plug flash into QVENC4K
. (File must be saved as “autorun” and not “autorun.txt”.). This will
reset the admin password back to the serial number of the unit You must have physical access to
the USB ports on the QVENC4K to use this procedure.
As shipped from the factory, the QVENC4K comes with SSH and root access disabled. The RPM
update system used, as discussed in the next section on Updating, prevents any unauthorized
firmware from entering the unit. Should the user require shell or SSH access to the unit, a public-
private certificate-based system can be enabled that disallows shell login via username/password
as a further security enhancement.
1.8 Updating
QVidium provides firmware updates from time to time to add new features, overcome limitations, or
to fix bugs. The QVENC4K firmware builds upon the RPM Package Manager to catalog, manage,
automate, secure, and simplify the update process. With a click to System/Update from the web
interface, the QVENC4K will connect with the QVidium update server via the Internet to take
inventory of which packages need to be updated and seamlessly keep the QVENC4K running with
the latest features and more robust firmware available. This secure mechanism forms a part of the
overall protections that help to prevent malware and all non-authorized firmware from infecting the
QVENC4K.
To update to the latest firmware, make certain that your unit has access to the Internet and click on
System/Update
, then confirm that you wish to proceed. The system will connect to the QVidium
server, take inventory of the packages loaded on your QVENC4K, and then proceed to determine
which packages need to be updated and download and install only those packages that need to be
updated. After this completes, you must reboot your system for the update to take effect by clicking
on System/Reboot from the web browser interface.
You should also clear your web browser’s
cache or at least refresh the web pages after updating the firmware in case the new firmware had
changed some of the web pages.
