Abstract
A system for providing synchronization and information exchange in a network such as a digital television broadcast network using a network management operations and control paradigm. A management entity component, such as a computer workstation operated at a control center, coordinates the actions of different agent components, such as hardware used at the headend or uplink site of a television network. The agent components are used to provide conditional access to a television signal by inserting conditional access data into the transmitted programming. Management information bases (MIBs) are provided for the agent components and the management component. The agent components update their MIBs with information of the communication network, such as changes in a television event schedule. The management component periodically reads the agents' MIBs to obtain the updated information and store it in its own MIB. The management component provides information to the agents' MIBs according to the updated information obtained from the agents to synchronize the insertion of data into the digital broadcast data stream by the agents.
