Foreword This Technical Report (TR) has been produced by Joint Technical Com
20、mittee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific
21、 field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organiz
22、ations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAN

In thi
24、s respect, the authors would like to thank all contributors to the process for their kind cooperation and would like to thank ETSI and CENELEC for all support in organizing the meetings and drafting thepresent document. Introduction The European Commissions eEurope 2005 Action Plan 1 for the further
25、 development of the Information Society includes among its priorities extending the role of digital television based on a multi-platform approach. The objective is to provide widespread access to advanced communications and information services for all European citizens, with increased broadband acc
26、ess. If widely implemented, digital interactive television may complement PC and Internet-based access to Information Society services in the EU. The goal of the present document is to define further standardization work in this field, in accordance with the European Commissions mandate 2 in support
27、 of digital TV and Interactive Services. This mandate follows the Commissions earlier invitation to the ESOs to assess how standardization can contribute to achieve the required level of interoperability; an invitation which resulted in the CENELEC report on standardization in digital interactive te
28、levision 3. The recommendations in this CENELEC report were developed through an examination of the relevant technical issues affecting the availability of interactive services across different EU markets and platforms, taking into account both existing relevant standards, and related ongoing standa
29、rdization activities. Other important considerations included the legal requirements of the relevant European regulatory framework and inputs from a range of stakeholders representing diverse interests. ETSI ETSI TR 102 282 V1.1.1 (2004-02)6In drafting the present document, a conscious effort was ma
30、de to match the objectives stated in the Framework Directive 4 with the requirements from the market, with respect to digital interactive television services. This Directive provides a regulatory framework for all electronic communications networks and services, in the context of increased convergen
31、ce in telecommunications, media and information technology; it specifically addresses digital and interactive services in the provisions of articles 17 and 18 in order to promote the free flow of information, media pluralism and cultural diversity. The Standardization Work Programme contained in the
32、 present document is intended to assist the European Commission and the market in furthering the state of interoperability of digital interactive television services. However, it is not within the mandate of the present document to determine or recommend whether any existing or proposed standard sho
33、uld or should not be made compulsory, or even whether such a standard should be included in the Commissions list of standards and specifications 5. ETSI ETSI TR 102 282 V1.1.1 (2004-02)71 Scope The present document encompasses the recommendation for a standardization Work Programme in the field of d
34、igital interactive television services. It applies the recommendations in the CENELEC report on Standardization in digital interactive television 3, taking into account developments since that document was written. In doing so it identifies additional standardization work in 4 interrelated areas tha
35、t were found to be relevant to the interoperability of digital interactive TV services. These areas are: i) functional receiver specifications; ii) Service Information; iii) APIs, execution and presentation engines; and iv) content authoring formats and guidelines. Work items in these areas have bee
36、n considered in respect of all types of interactive services. The Work Programme defines a set of deliverables, a timeline for the execution of specified work items and the identification of the appropriate industry consortiums and ESOs to carry out the work. In doing so it takes into account releva
37、nt ongoing standardization activity as well as the legal requirements of the regulatory framework. Taken together, the items in the Work Programme provide a collection of additional tools that will assist stakeholders in significantly improving the availability of digital interactive television serv
38、ices across new as well as established digital interactive television markets. 2 References For the purposes of this Technical Report (TR), the following references apply: 1 COM(2002) 263: “Communication from the Commission to the Council, the European Parliament, the Economic and Social Committee a
