7、018) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for
8、 studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study
9、 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 areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis w
10、ith ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory pro
11、visions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of
12、 such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no posi
13、tion concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, prote
14、cted by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

17、J.207 (03/2018) 1 Recommendation ITU-T J.207 Specification for an integrated broadcast and broadband digital television application control framework 1 Scope In accordance with the requirements defined in ITU-T J.205 and based on the viewpoint of ITU-T J.206, this Recommendation provides guidance fo
18、r administrations and entities who intend to provide integrated broadcast-broadband (IBB) digital television (DTV) services. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. A
19、t 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 Recommendations and other references listed
20、below. A list of the currently valid ITU-T Recommendations is regularly published. The reference to a document within this Recommendation does not give it, as a stand-alone document, the status of a Recommendation.

ITU-T J.207 (03/2018) 6 The IBB DTV systems The IBB DTV systems considered in this Recommendation are the sy
24、stems listed in clause 3.1 of ITU-R BT.2075. The summary of each system in clause 3.2 of ITU-R BT.2075 should also be used. 7 Service capabilities of the IBB DTV systems This clause describes which service capabilities are provided in each system. 7.1 Items to be considered Items listed and describe
25、d in clause 4.1 of ITU-R BT.2075 should be used with the following modification. The seventh list entry on companion device collaboration should be modified as follows: Companion device collaboration: Companion devices are those devices used with an IBB DTV receiver for presentation and interaction.
26、 Collaboration with companion devices is considered to be an effective presentation method, and user interaction is controlled by applications. Scenarios and requirements for the services using companion device collaboration are described in b-ITU-T J.230. IBB DTV systems should take into account th
27、e definitions and requirements in this Recommendation. 7.2 Consideration on service capabilities Table 1 of ITU-R BT.2075 should be used. 8 Technical elements of the IBB DTV systems This clause describes how technical elements are designed in each system. 8.1 Items to be considered Items listed and
28、described in clause 5.1 of ITU-R BT.2075 should be used with the following modification. In item c), description of this item should be modified to incorporate a reference. c) Supported application types In ITU-T J.205, several application types are defined. Supported application types are fundament
29、al system designs of IBB DTV systems. Hence, describing supported application types to characterize IBB DTV systems is useful. 8.2 Consideration on technical elements Table 2 of ITU-R BT.2075 should be used. Rec.
