25、1.1 Background The IPTV Security Solution defined in the ATIS-0800014 1 provides a set of profiles which define the characteristics of the Chain-of-Trust and Execution Environment of an IPTV Terminal Function. In addition, ATIS-0800024 3 defines the characteristics of a Secure Execution Environment.

26、 This specification provides an XML schema for the Execution Environment profiles for use in services and functions within an IPTV solution. 1.2 Scope This document provides a description of the associated Fault Code schema file. 2 REFERENCES The following standards contain provisions which, through

27、 reference in this text, constitute provisions of this ATIS Standard. At the time of publication, the editions indicated were valid.

31、HEMA DESCRIPTION (INFORMATIVE) 4.1 Overview/Background Please refer to ATIS-0800014 1, section 6.2, for information about the ITF Execution Environment. 4.2 Overview of the Schema This XML schema has been developed in order to define the format of an XML document representing the Profile and any ass

32、ociated Profile Level of the Execution Environment equipped in the ITF. A single element represents the Execution Environment capabilities with a value that is selected from a defined enumeration that fully represents the ISS Security Profiles defined in ATIS-0800014 1 and the ISS Profile Levels def

33、ined in ATIS-0800024 3. The XML Schema does not represent individual capabilities of the ISS Security Profiles. 5 ITF EXECUTION ENVIRONMENT XML SCHEMA SPECIFICATION (NORMATIVE) 5.1 XML Schema The ITF execution environment XML schema that has been developed by the ATIS IIF is associated with the “itf

34、ee:” XML namespace. The full ITF Execution Environment XML schema is in the form of a “.xsd” file, which is contained in a “zip” archive that accompanies this specification. In the event of any conflict, this “.xsd” file takes precedence over the XML schema definitions in the present document. The f

35、ormal definition of the ATIS IIF itfee: namespace is: xmlns:itfee=“http:/www.atis.org/schemas/0800036/itfee/1“ The ATIS ITF Execution Environment XML schema imports XML Description Schemes from the W3C XML specification 2. The namespaces of these schemes are: xmlns=“http:/www.w3.org/2001/XMLSchema“

36、5.2 ITF Execution Environment XML schema Implementation The following type declaration is made to describe the possible ISS profiles and SEE levels associated with those profiles where permitted.

41、 transaction needs to be defined to relay this information from the ITF. 5.4 Use of ISSProfileLevelType in Program Metadata ATIS-0800020 4 defines program metadata for offered content. In some situations, there may be a requirement for a content item to only be played out on an ITF that implements a

42、 particular ISS Profile. It is also possible for a content item to require one of several ISS Profiles on the ITF and as such, the program metadata for the content item shall list all the ISS Profiles of which the ITF must implement one.

43、IS-0800036 5 Table 3: RequiredEEProfile element in program metadata Name R/O Semantics RequiredEEProfile O States the Execution Environment profile needed in the ITF in order to playout the content item. Multiple items are permitted, of which the Execution Environment in the ITF must match one in or

44、der to playout the content item. When omitted, there is no requirement placed on the Execution Environment. It should be noted that the RequiredEEProfile information in the program metadata is for informational use only. The ITF shall determine if playout of the content item is possible. ATIS-080003
