Abstract: The present invention relates to an apparatus and a method for configuring a control message in a broadcasting system for supporting a multimedia service based on an internet protocol. To this end, control information to be recorded in a payload of a control message to be configured is generated based on a table selected from among a plurality of tables for defining the information related to the generation and consumption of a hybrid content when a message type of the control message to be configured is determined to be a type for providing information related to the generation and consumption of a hybrid content. In addition, the information related to the type of the selected table is recorded in an optional field of the control message to be configured.
