A network management system for use in a dynamic broadcast system, which is configured for providing content to terminals, said network management system comprising: - a decision unit that is configured to dynamically decide transmission parameters, transmission times and transmission paths used for broadcasting content by a terrestrial broadcast transmitter via a terrestrial broadcast network and for providing content by a broadband server via a broadband network, - a controller that is configured to dynamically control, initiated by the decision unit, transmission parameters, transmission times and transmission paths used for broadcasting content via said terrestrial broadcast network and for providing content via said broadband network, to dynamically control multiplex configurations of the transmission of content including the allocation of content to content data streams transmitted over the terrestrial broadcast network or the broadband network, and to control the terrestrial broadcast transmitter to reduce the transmission power of a terrestrial broadcast channel or switch off a terrestrial broadcast channel, - a dynamic white space database unit that is configured to store and dynamically update a dynamic white space database of frequency resources, which are assigned for broadcasting broadcast content but are available for use by one or more white space devices, and - a spectrum server that is configured to dynamically manage frequency resources, which are comprised in the dynamic white space database, for use by said one or more white space devices, wherein said decision unit is configured to dynamically decide transmission parameters, transmission times and transmission paths based on monitoring data carrying information on user specific content usage, said monitoring data including information on content popularity, watching behavior and user interests, and wherein said decision unit is configured to take information provided by said spectrum server about spectrum requests by white space devices into account in order to dynamically decide transmission parameters, transmission times and transmission paths used for broadcasting and providing content. - a decision unit that is configured to dynamically decide transmission parameters, transmission times and transmission paths used for broadcasting content by a terrestrial broadcast transmitter via a terrestrial broadcast network and for providing content by a broadband server via a broadband network, - a controller that is configured to dynamically control, initiated by the decision unit, transmission parameters, transmission times and transmission paths used for broadcasting content via said terrestrial broadcast network and for providing content via said broadband network, to dynamically control multiplex configurations of the transmission of content including the allocation of content to content data streams transmitted over the terrestrial broadcast network or the broadband network, and to control the terrestrial broadcast transmitter to reduce the transmission power of a terrestrial broadcast channel or switch off a terrestrial broadcast channel, - a dynamic white space database unit that is configured to store and dynamically update a dynamic white space database of frequency resources, which are assigned for broadcasting broadcast content but are available for use by one or more white space devices, and - a spectrum server that is configured to dynamically manage frequency resources, which are comprised in the dynamic white space database, for use by said one or more white space devices, wherein said decision unit is configured to dynamically decide transmission parameters, transmission times and transmission paths based on monitoring data carrying information on user specific content usage, said monitoring data including information on content popularity, watching behavior and user interests, and wherein said decision unit is configured to take information provided by said spectrum server about spectrum requests by white space devices into account in order to dynamically decide transmission parameters, transmission times and transmission paths used for broadcasting and providing content.
