1 Scope
This part of IEC 62481 , the DLNA guidelines, specifies DLNA guidelines for DRM Interoperability Solutions (DIS), which are defined as methods to enable the secure transfer and use of protected commercial content between different implementations on network media devices. This content could be protected by different content protection technologies. In this document, they are referred to as DRMs. The guidelines are not intended to replace or disable other interoperability mechanisms that could already be in place, for example DLNA Link Protection guidelines stated in IEC 62481 -3:201 7 or mechanisms provided by underlying DRMs.

3 Terms, definitions and conventions
For the purposes of this document, the terms and definitions given in IEC 62481 -1 -1 :201 7 and the following apply.3.1 Terms and definitions 3.1 .1 Copy propagating content from a source device to a destination device such that the source device maintains its original version of this content 3.1 .2 Move propagating content from a source device to a destination device such that the source device no longer maintains a usable copy of this content 3.1.3 DIS DRM Interoperability System means for content to be protected by DRM A on one device to be transformed to the same content protected by DRM B on another device 3.1.4 DRM Digital Rights Management system for protecting the copyrights of electronic digital media 3.1.5 DTCP-IP DIS Digital Transmission Content Protection over Internet Protocol Digital Rights Management Interoperability System Note 1 to entry: DIS implemented according to the DTCP-IP specification. 3.2 Conventions In IEC 62481 -1 -1 :201 7 and this document, 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 in lowercase (e.g., Move). Any lowercase uses of these words have the normal technical English meanings.
5 Guideline requirements
5.1 General See 7.1 of IEC 62481 -1 -1 :201 7, for guideline and attribute table layout descriptions. 5.2 Common DRM interoperability guidelines 5.2.1 General This document 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-IP 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. 5.2.2 Media management – MM/CP additional MM flags-param (flags parameter) [G UIDELINE ] The primary-flags token as defined in 1 0.1 .3.24.2 (GUN 3WJUU) of IEC 62481 -1 -1 :201 7, are extended for DLNA DIS with additional bit mappings. The additional bit mappings of primary-flags for DLNA DIS shall be as follows.
