<p>The invention provides a method for facilitating the management and running of a digital video broadcast (DVB) system. In a typical DVB system there are often a number of functions which must be co-ordinated and synchronized. The invention provides a monitoring point for managing the total multiplex, and controlling the mix of services being transmitted. The system fulfils most of the software integration requirements in a broadcast centre. A central database, held in the operational areas, is provided and is the reference point to which other systems refer. A large protocol converter is provided which links the scheduling system to the playout and conditional access (CA) systems.</p> |
