DMIF, or Delivery Multimedia Integration Framework, is an interface between the application

'''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.<ref>{{cite web | url=http://www.iso.org/iso/iso_catalogue/catalogue_ics/catalogue_detail_ics.htm?csnumber=34418 | title=ISO/IEC 14496-6:2000 - Information technology -- Coding of audio-visual objects -- Part 6: Delivery Multimedia Integration Framework (DMIF) | author=ISO | publisher=ISO | access-date=2010-08-01}}</ref> DMIF defines two interfaces: the DAI (DMIF/Application Interface) and the DNI (DMIF-Network Interface).<ref>{{cite web | url=http://mpeg.chiariglione.org/faq/mp4-dmi/mp4-dmi.htm | title=MPEG Systems (1-2-4-7) FAQ, Version 16.0 - Delivery Multimedia Integration Framework (DMIF) |year=2001 | author=MPEG | publisher=MPEG | access-date=2010-08-01}}</ref><ref>{{cite web |url=http://mpeg.chiariglione.org/tutorials/papers/icj-mpeg4-si/06-DMIF_paper/6-DMIF_paper.htm |title=The Delivery Layer in MPEG-4 - G.

and the transport, that allows the MPEG-4 application developer to stop worrying about that

transport. 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

remote interactive peer, broadcast or local storage media.

•* Use of homogeneous networks between interactive peers: [[Internet Protocol|IP]], ATM, mobile, [[PSTN]], narrowband [[ISDN]].

• Control of the establishment of FlexMux channels

•* Support for mobile networks, developed together with ITU-T

• Use of homogeneous networks between interactive peers: IP, ATM, mobile, PSTN,

•* UserCommands with acknowledgment messages.

Narrowband ISDN.

•* Management of MPEG-4 Sync Layer information

• Support for mobile networks, developed together with ITU-T

• UserCommands with acknowledgment messages.

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''.<ref>{{cite web | url=http://mpeg.chiariglione.org/meetings/stockholm/stockholm_press.htm | title=mpeg Press & Public Release - Stockholm | date=July 1997 | author=MPEG | publisher=MPEG | access-date=2010-08-01 | url-status=dead | archive-url=https://web.archive.org/web/20100705170133/http://mpeg.chiariglione.org/meetings/stockholm/stockholm_press.htm | archive-date=2010-07-05 }}</ref><ref>{{cite web | url=http://mpeg.chiariglione.org/faq/mp2-dsm/mp2-dsm.htm |title=DSM-CC FAQ Version 1.0 |date=1997-02-21 |author=MPEG | publisher=MPEG |access-date=2010-08-01}}</ref><ref>{{cite web | url=http://mpeg.chiariglione.org/technologies/mpeg-2/mp02-dsm/dsmcc/dsmcc.htm |title=An Introduction to Digital Storage Media - Command and Control (DSM-CC) |date=1996 |author=IEEE | publisher=MPEG |access-date=2010-08-01}}</ref> DMIF was also a name of working group within Moving Picture Experts Group.
