Abstract

Provided are apparatuses and methods in a digital broadcast transmission system for identifying a desired ESG fragment in a list of ESG fragments. The list of ESG fragments or bootstrap ESG may be created by a designated service provider, operator or other apparatus or system. The bootstrap ESG may contain information on, or refer to, secondary ESG fragments. In addition, the secondary ESG fragments may contain information on, or refer to, other ESG fragments in a hierarchical arrangement. A mobile terminal may identify a desired ESG fragment from the bootstrap ESG by identifying criteria within the bootstrap ESG corresponding to a secondary ESG, for example.
