Unified Architecture for DVB-H Electronic Service Guide

Presently, there are three main ESG systems used in DVB-H (DVB, 2004) systems : 1. CBMS (DVB, 2006), promoted by the digital video broadcasting project (DVB). 2. OAI (NOKIA, 2006), promoted by NOKIA. 3. OMA (OMA, 2006), still in draft version, promoted by the open mobile alliance. All of them have a lot of similarities and are based on same concepts and technologies. Some of these similarities are: • The use of XML (W3C, 1998) to describe fragments. • The use of FLUTE (Paila, Luby, Lehtonen, Roca, & Walsh, 2004) as transport protocol. • A similar data model. • All of them can split the broadcast contents in several sessions.
