The present invention relates to a method for providing a digital broadcast, and for providing a semantic application from a receiver for executing the semantic application, which is provided independently from the digital broadcast, and comprises the steps of: (a) executing at least one first semantic application based on a first event while providing the digital broadcast; (b) executing at least one second semantic application based on a second event while executing step (a); and (c) managing the state of the at least one first semantic application depending on the property of same while executing step (b). According to the present invention, a plurality of semantic applications can be provided, and the state of each of the plurality of semantic applications can be managed according to the property and execution mode of the semantic applications, even in an environment where the plurality of semantic applications are executed, thereby efficiently using a system resource of the receiver. |
