Extended metadata and adaptive program service providing system and method for providing digital broadcast program service

The present invention relates to extend metadata for providing a digital broadcast program service to diverse kinds of terminals, and a system and method for providing an adaptive program service to the terminals by using the extended metadata. The system and method performs integrated management of resource information suitable for a combination of all (terminal, program and user) conditions of the personal terminal, manages resource-related information separately from temporal/spatial location information, and thus provides an adaptive program service by using extended metadata and recomposing an adaptive scene for a personal terminal so as to provide the digital broadcast service adaptively to diverse terminal environments on a home network. The extended metadata include: segmentation metadata including description information on a significant segment that forms the broadcast program; and resource description metadata including description information on lower composition resources of the segment in order to provide a broadcast program to the diverse kinds of terminals.
