Networking in the OVS System
System Architecture 2-31
Broadcast Data Service
The broadcast data service manages broadcast scheduling information in the
database. The broadcast data service reads broadcast scheduling information, such
as schedules, from the database and writes it to memory where it can be read by
the scheduler service and by exporter services, such as the NVOD exporter service.
The broadcast data service also provides interfaces enabling you to schedule
broadcast events.
Scheduler Service
The scheduler service keeps track of the current time and a list of scheduled events
and notifies the appropriate exporter service, such as the NVOD exporter service,
when a broadcast event is scheduled to occur.
NVOD Exporter Service
The NVOD exporter service plays a scheduled logical content title on a scheduled
channel when notified by the schedule service. You can use this service to handle
any scheduled video, including NVOD, pay-per-view, or regular TV broadcasting.
Networking in the OVS System
The OVS system can be deployed on many different network types. Depending on
the environment, these networks can be either:
■
a PSTN (public switched telephone network) using IP (Internet Protocol) and
TCP (Transmission Control Protocol) or UDP (User Datagram Protocol)
network used in Internet environments
■
a LAN (local-area network), typically used in intranet environments
■
Broadband Network , used in the broadband environment
