Cisco Live Event Controller
Description
The Cisco
®
Live Event Controller (LEC) is a server used by programmers and broadcasters to perform uplink-
commanded, dynamic channel tuning for receivers. It provides the capability for programmers and broadcasters to
manage the access rights of services based on event groups (Figure 1). Users define the event groups and assign
decoders to the groups on the Cisco PowerVu
®
Network Centre (PNC). Once decoders are assigned to groups,
users can create and schedule live tuning events on the LEC. Decoders can be tuned by live events. The start and
end times of an event are dynamically controlled by pushing a button. This feature provides users with an extra
level of flexibility in managing services.
Figure 1. Overview of Live Event Tuning Mechanism
Cisco LEC is a server with an Asynchronous Serial Interface (ASI) card that interfaces with the multiplexer ASI
card to pass through the event control data. The LEC also interfaces with the PNC and a General Purpose Input
(GPI) module through Ethernet connections. The LEC client is accessed through the PNC GUI client.
The PNC monitors the LEC application. Network services and event group data are automatically coordinated
between the PNC and LEC. Channel tuning events are imported through an easy-to-use web interface, and are
triggered based on time or GPI triggers (button pushes). Event control data can be targeted to different groups of
receivers. Receivers with LEC support are tuned to a designated channel based on event control data instructions.
