25、Electronics (CE), mobile, and Personal Computer (PC) domains. As such, they want to conveniently enjoy the content, regardless of the source, across different devices and locations in the home. The digital home vision integrates the Internet, mobile, and broadcast networks through a seamless, intero
26、perable network, which will provide a unique opportunity for manufacturers and consumers alike. In order to cater for this need, a common set of industry design guidelines is needed that allows vendors to participate in a growing marketplace, leading to more innovation, simplicity, and value for con
27、sumers. This International Standard serves that purpose and provides vendors with the information needed to build interoperable networked platforms and devices for the digital home.

28、BILITY GUIDELINES Part 4: DRM interoperability solutions 1 Scope This part of IEC 62481 specifies DLNA guidelines for DRM interoperability. The set of guidelines in this part of IEC 62481 are based on DLNA DRM Interoperability Solutions (DIS), which are defined as methods to enable the secure transf
29、er and use of protected commercial content among different implementations on network media devices. This content could be protected by different content protection technologies. In this standard they are referred to as DRMs. The guidelines are not intended to replace or disable other interoperabili
30、ty mechanisms that could already be in place, e.g. DLNA Link Protection guidelines stated in IEC 62481-3 or mechanisms provided by underlying DRMs. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicati

38、P-IP DIS DIS implemented according to the DTCP-IP specification 3.3 Conventions In IEC 62481-1:2013 and this standard, a number of terms, conditions, mechanisms, sequences, parameters, events, states, or similar terms are printed with the first letter of each word in uppercase and the rest lowercase
39、 (e.g., Move). Any lowercase uses of these words have the normal technical English meanings. 4 Networking architecture, device models and guideline conventions 4.1 DLNA home networking architecture See IEC 62481-1:2013, Clause 4, for a full description of the DLNA home networking architecture. 4.2 D
40、LNA device model See IEC 62481-1:2013, Clause 5, for a full description of the DLNA device model. This standard extends the existing DLNA Device Classes and Device Capabilities to include protected content used for the following System Usages: Upload System Usage; Download System Usage; BS EN 62481-
41、4:2014 8 IEC 62481-4:2014 IEC 2014 Upload Synchronization System Usage; Download Synchronization System Usage. 4.3 Guideline terminology and conventions See IEC 62481-1:2013, Clause 6, for a full description of the DLNA document conventions. 5 Guideline requirements 5.1 General See 7.1.1 in IEC 6248
42、1-1:2013, for guideline and attribute table layout descriptions. 5.2 Common DRM interoperability guidelines General 5.2.1This standard defines the usage guidance for the DTCP-IP DLNA DIS technology. For convenience, the term “DTCP-IP DIS” is used to mean the DTCP-IP technology for a DLNA DIS. DTCP-I
43、P DIS provides Copy and Move functionality by means of the transcription interoperability scenario. DTCP-IP DIS supports the Upload System Usage, Download System Usage, Upload Synchronization System Usage, and Download Synchronization System Usage. Media management MM/CP additional MM flags-param (f
44、lags parameter) 5.2.2GUIDELINE The primary-flags token as defined in 7.4.1.3.23.2 (GUN 3WJUU) of IEC 62481-1:2013, are extended for DLNA DIS with additional bit mappings. The additional bit mappings of primary-flags for DLNA DIS shall be as follows. Bit 31 to Bit 14 are as defined in 7.4.1.3.23.2 (G
45、UN 3WJUU) of IEC 62481-1:2013. Bit 13: DIS-DTCP-copy flag (DTCP-IP DIS Copy flag) applies only to the HTTP Media Transport; if the flags-param is omitted then this flag shall have an inferred value of false; see guidelines 5.3.2.2.2 and 5.3.2.2.3 for more information. Bit 12: DIS-DTCP-move flag (DTC
46、P-IP DIS Move flag) applies only to the HTTP Media Transport; if the flags-param is omitted then this flag shall have an inferred value of false; see guidelines 5.3.2.3.2 and 5.3.2.3.3 for more information. All other bits in primary-flags are reserved for future use and shall have a value of false.
