Chapter 3 Configuring the NewsBrowse System
Prepare for core configuration stages
Do the following tasks in preparation for the configuration of core system
functionality.
Prepare NetTime
NetTime keeps the system clocks on NewsBrowse machines in sync. Since the Profile
Media Servers and single-channel encoders use the house timecode feeds, the other
machines need to be kept in sync as well. On systems that control ingest and have
single-channel encoders, the primary purpose of NetTime is to keep the Ingest
Scheduler, which runs on the NewsBrowse server, and the NewsBrowse client
machines synchronized to house time. On systems that do not control ingest, NetTime
is still useful to keep clocks synchronized so that system logs can be correlated.
The following procedure uses a single-channel encoder as the Adrienne Absolute
Time Server. If your system does not control ingest and has no single-channel
encoders, you can use any machine as the Adrienne Absolute Time Server.
The single-channel encoder runs the Adrienne Absolute Time Server. NetTime clients
on the production network reference the Adrienne Absolute Time Server. A NetTime
server runs on the NewsBrowse server, which rebroadcasts the time to the client
network. NetTime clients on the client network reference the NetTime server.
Refer to “NetTime system” on page 11 for a diagram of the NetTime system.
Set up NetTime with the following procedures:
• “Prepare NetTime servers” on page 38
• “Prepare NetTime clients” on page 39
Prepare NetTime servers
You use one single-channel encoder as the primary Adrienne Absolute Time Server,
and another single-channel encoder as the secondary (redundant) Adrienne Absolute
Time Server. A LTC connection to house timecode is required for single-channel
encoders functioning as Adrienne Absolute Time Servers.
NOTE: Make sure that the Thomson Ingest Control service is off before starting
this procedure. If the service is on and you run AecPciPoll.exe, the single-channel
encoder locks up.
To prepare a single-channel encoder as a Adrienne Absolute Time Server, do the
following:
1. On the single-channel encoder, run the following:
C:\AecPciPoll.exe
