First Claim
Patent Images
1. A dynamic broadcast system for providing content to terminals comprising:
- a broadcast transmitter that broadcasts content via a broadcast network;
a broadband server that provides content via a broadband network;
a controller that dynamically controls transmission parameters, transmission times and transmission paths for broadcasting content via the broadcast network and providing content via the broadband network;
a dynamic white space database unit that stores and dynamically updates a dynamic white space database of frequency resources, which are assigned for broadcasting broadcast content but can locally not be used for broadcasting;
processing circuitry that dynamically decides transmission parameters, transmission times and transmission paths for broadcasting and providing content;
one or more white space devices that access frequency resources that are included in the dynamic white space database; and
a spectrum server that dynamically manages frequency resources that are included in the dynamic white space database for access by the one or more white space devices.

Abstract
A dynamic broadcast system and a spectrum management device for use in a dynamic broadcast system. A dynamic white space database unit stores and dynamically updates a dynamic white space database of frequency resources that are assigned for broadcasting broadcast content but can locally not be used for broadcasting. One or more white space devices can access the frequency resources included in the dynamic white space database. A spectrum server dynamically manages the frequency resources included in the dynamic white space database for access by the one or more white space devices.

15. A dynamic broadcast method for providing content to terminals, the method comprising:
-
broadcasting content via a broadcast network; providing content via a broadband network; controlling transmission parameters, transmission times and transmission paths for broadcasting content via said broadcast network and providing content via said broadband network; storing and dynamically updating a dynamic white space database of frequency resources, which are assigned for broadcasting broadcast content but can locally not be used for broadcasting; deciding transmission parameters, transmission times and transmission paths for broadcasting and providing content based on monitoring data including information indicating at least one of user specific content usage, transmission quality of a transmission link between the broadband server and a terminal and reception of content broadcast by the broadcast transmitter; and dynamically managing frequency resources that are included in the dynamic white space database for access by one or more white space devices that access the frequency resources included in the dynamic white space database.
