Synchronizing system clocks
If you are using a K2 Media Client with internal storage, then synchronizing system
clocks is not required. However, if you are using a K2 Media Client with external
storage or as part of a larger network, the system clocks on the devices of the K2
system must be kept synchronized. The main purpose for this time synchronization is
so that entries in the various logs on the K2 system devices can be correlated. The
following procedure describes a mechanism by which clocks are synchronized. If
your facility has other mechanisms by which you synchronize system clocks, you can
use your own methods, as long as it accomplishes the goal of keeping the system
clocks synchronized.
To synchronize system clocks, do the following:
1. Designate a K2 Media Server as the time server.
2. On each K2 Media Client, iSCSI client, and any additional K2 Media Servers, in
the Windows Control Panel open Date and Time .
3. On the Internet Time tab, enter the K2 Media Server that is the time server.
Licensing
For SD-only models, a codec upgrade license is available that adds D10 and DV50
compression and increases available MPEG-2 compression data rate up to 50Mbs,
4:2:2. Contact your Grass Valley representative to purchase the license. Instructions
are provided when you receive the upgrade kit.
Some optional applications, such as TimeDelay, are also available for use with K2
systems. Contact your Grass Valley representative for licensing information.
Security considerations
To provide a basic level of security, the K2 Media Client ships from the factory with
four different security levels. The following table shows the different types of K2 user
and their privileges. The password is case sensitive.
