DMIF, or Delivery Multimedia Integration Framework, is a uniform interface between the application and the transport, that allows the MPEG-4 application developer to stop worrying about that transport. DMIF was defined in MPEG-4 Part 6 (ISO/IEC 14496-6) in 1999. DMIF defines two interfaces: the DAI (DMIF/Application Interface) and the DNI (DMIF-Network Interface). A single application can run on different transport layers when supported by the right DMIF instantiation. MPEG-4 DMIF supports the following functionalities: * A transparent MPEG-4 DMIF-application interface irrespective of whether the peer is a remote interactive peer, broadcast or local storage media. * Control of the establishment of FlexMux channels * Use of homogeneous networks between interactive peers: IP, ATM, mobile, PSTN, narrowband ISDN. * Support for mobile networks, developed together with ITU-T * UserCommands with acknowledgment messages. * Management of MPEG-4 Sync Layer information DMIF expands upon the MPEG-2 DSM-CC standard (ISO/IEC 13818-6:1998) to enable the convergence of interactive, broadcast and conversational multimedia into one specification which will be applicable to set tops, desktops and mobile stations. The DSM-CC work was extended as part of the ISO/IEC 14496-6, with the ''DSM-CC Multimedia Integration Framework (DMIF)''. DSM-CC stands for ''Digital Storage Media - Command and Control''. DMIF was also a name of working group within Moving Picture Experts Group. The acronym "DSM-CC" was replaced by "Delivery" (Delivery Multimedia Integration Framework) in 1997. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Delivery Multimedia Integration Framework」の詳細全文を読む スポンサード リンク
