Abstract

Disclosed is a method and system for efficiently providing a multi-content, including a plurality of contents in one service, by means of a service guide upon providing the multi-content in an Open Mobile Alliance (OMA) mobile broadcasting system. When a broadcast transmitting apparatus provides a broadcast receiving apparatus with a multi-content by inserting a plurality of content into one service, the broadcast transmitting apparatus sets one of the plurality of content as a primary content, and provides a service guide including primary-content setting information to the broadcast receiving apparatus. The primary content represents a content set to be primarily provided to a user, among a plurality of content included in one service and simultaneously provided during a specific time period. The primary-content setting information represents information for identifying the primary content. The primary-content setting information may be included in a content fragment or schedule fragment of a service guide.
