3、r for harmonized procedural content formats for interactive TV applications. Since this Recommendation was approved in 2003, several procedural content formats for interactive TV applications developed by other standardization bodies have been updated or newly developed. Updated specifications inclu
4、de: DVB-GEM, DVB-MHP 1.0, DVB-MHP 1.1, DVB-MHP 1.2, OCAP-1.0, OCAP-1.1 and ARIB STD-B23. Also, ATSC developed ACAP and ABNT has now developed GINGA-J. The purpose of the third revision of this Recommendation is to harmonize the specifications with a wider variety of standards including GEM 1.2, ARIB
5、-J, GINGA-J, DVB-MHP, ACAP and OCAP. To achieve this, the common core defined in this Recommendation consists of two sets of APIs; one related to core Java technology and another for broadcast extensions, to conform to either DVB-GEM, from which several specifications are derived, or JavaDTV specifi
6、cation, which is the core of GINGA-J and functionally equivalent to DVB-GEM. Additional APIs specific to the standards listed above are included for information in the appendices, which are not included in the harmonized common core.

ITU-T J.202 (08/2010) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication tech
8、nologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telec
9、ommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some ar
10、eas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized op
11、erating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “sha
12、ll“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the pr
13、actice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation deve
14、lopment process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

19、-T J.202 (08/2010) 1 Recommendation ITU-T J.202 Harmonization of procedural content formats for interactive TV applications 1 Scope This Recommendation is intended to harmonize the application environment for interactive TV applications. The potential for commonality in the procedural application en
20、vironment is based on the analysis of the common core identified in the work leading to this Recommendation. Such commonality would benefit content providers through knowledge of commonly adopted procedural functionality and economies of scale. NOTE The structure and content of this Recommendation h
21、ave been organized for ease of use by those familiar with the original source material; as such, the usual style of ITU-T Recommendations has not been applied. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute p
22、rovisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommend
23、ations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published.

26、rm definitions for interactive TV using procedural applications The recommended platform definitions for interactive TV consist of: 1) the common core in Annex A which is derived from the commonality in ETSI TS 102 728, ABNT 15606-6, b-ABNT 15606-4, b-ARIB B23, b-ETSI ES 201 812, b-OCAP 1.0, b-OCAP
27、1.1, b-ATSC ACAP, b-ETSI TS 102 812, b-ETSI TS 102 727. The strict adherence to the APIs in Annex A ensures binary interoperability; 2) the additional APIs as defined either: in clause B.1 to conform to the specification given in ETSI TS 102 728. These APIs are intended for harmonization among stand
28、ards derived from ETSI TS 102 728; or in clause B.2 to conform to the specification given in ABNT 15606-6 specification. These APIs are intended as a functional equivalent to ETSI TS 102 728 and can be used as an alternative to it; 3) the complete specifications that build on the common core defined
29、 in Annexes A and B by providing additional guarantees required by individual organizations, where necessary; 4) the system-specific additions such as those given in Appendices I through VII and possible future additions, if necessary. Further, attention is drawn to the fact that where there are cur
30、rent systems, such as b-ARIB B24 and b-ISO/IEC 13522-5, which are in extensive use, the addition of some functionalities may be required to assist migration to the harmonized system in the future. An example is given in Appendix VIII. Rec. ITU-T J.202 (08/2010) 3 Annex A Common core APIs (This annex

ITU-T J.202 (08/2010) Annex B Broadcast extension APIs (This annex forms an integral part of this Recommendation) This annex describes broadcast extension APIs in addition to those listed in Annex A. APIs which are in
35、tended to provide harmonization among standards derived from ETSI TS 102 728 are described in clause B.1. APIs for those functionalities derived from ABNT 15606-6 are described in clause B.2. B.1 Additional APIs to conform to globally executable MHP In this clause, additional APIs to the common core
36、 in Annex A are defined. These are intended to provide harmonization among standards derived from ETSI TS 102 728. The standards are b-ETSI ES 201 812, b-ETSI TS 102 812, b-ETSI TS 102 727, b-OCAP 1.0, b-OCAP 1.1, b-ATSC ACAP and b-ARIB B23. These additional APIs should be used in conjunction with c
37、ommon core APIs. NOTE ETSI TS 102 728 covers the broadcast IPTV targets. There are a few APIs that are not required when only the broadcast target is implemented. Similarly, there are a few APIs that are not required when only the IPTV target is implemented. However, when a broadcast target or a hyb
38、rid broadcast and IPTV target is implemented, it is mandatory that all the required APIs and other definitions are included as specified in this Recommendation. org.davic.media org.davic.resources org.davic.mpeg org.davic.mpeg.sections .tuning org.dvb.applications org.dvb.dsmcc org.dvb.event org.dv
