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. 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.
