Foreword This Technical Report (TR) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications St
15、andards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, wh
16、ich is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has acti

18、rivate sector organizations in the television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-led systems, which meet the real need
19、s, and economic circumstances, of the consumer electronics and the broadcast industry. Introduction IP Datacast over DVB-H is an end-to-end broadcast system for delivery of any types of digital content and services using IP-based mechanisms optimized for devices with limitations on computational res
20、ources and battery. An inherent part of the IP Datacast system is that it comprises a unidirectional DVB broadcast path that may be combined with a bi-directional mobile/cellular interactivity path. IP Datacast is thus a platform that can be used for enabling the convergence of services from broadca
21、st/media and telecommunications domains (e.g. mobile/cellular). The concept of the present document is to provide a number of elementary use cases which can be combined to complex real-life IP Datacast use cases. In clause 4.1, those elementary use cases are listed in logical groups. They are descri
22、bed and requirements and data flows are shown. In clause 4.2, services are presented, serving as examples on how to use those elementary use cases. ETSI ETSI TR 102 473 V1.1.1 (2006-04) 5 1 Scope The present document reflects use cases and services which may be used with IP Datacast over DVB-H. Info

These use cases do not reflect entire appl

These logical groups are fairly orthogonal to each other, so they may be combined according to the needs for a certain system. 4.1 Interactivity mode based el
