7、nited 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 studying technical, operating and tariff questions and issuing Recomm
8、endations 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 groups which, in turn, produce Recommendations on these topics. The a
9、pproval 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 with ISO and IEC. NOTE In this Recommendation, the expression “Administ
10、ration“ 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 provisions (to ensure, e.g., interoperability or applicability) and compl
11、iance 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 such words does not suggest that compliance with the Recommendation i
12、s 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 position concerning the evidence, validity or applicability of claimed Int
13、ellectual 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, protected by patents, which may be required to implement this Recommendatio
14、n. 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/.

18、-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. At the time of publication, the editions indicated were valid. All Recomme

24、ec. ITU-T J.207 (03/2016) 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 described in clause 4.1 of ITU-R BT.2075 should be used with the following modification. The seventh list
25、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. Collaboration with companion devices is considered to be an effective presentation method, and us
26、er 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 the definitions and requirements in that Recommendation. 7.2 Consideration on service capabilities T
