FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC National Committees and ISO member bodies.
3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to
ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held
responsible for the way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees and ISO member bodies undertake to
apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and
regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding
national or regional publication should be clearly indicated in the latter.
5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not responsible
for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC National Committees or ISO member bodies for any
personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for
costs (including legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC
publication or any other IEC, ISO or ISO/IEC publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC publication may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

The application profile for a remote media access application shall be implemented as
specified in Clause 5. The application scenarios of remote media access shall be
implemented as specified in Clause 6. The remote media access system architecture and
components of an IGRS Remote Access Media Server (RAMS) and Remote Access Media
Client (RAMC) shall conform to Clause 7. The message and data formats used in a remote

5 Overview of IGRS remote media access profile
IGRS remote access (RA) application profiles are based on the IGRS RA core protocol
(ISO/IEC 14543-5-8:2017) and the IGRS RA service platform protocol (ISO/IEC 14543-5-
9:2017). The IGRS RA application profiles specify functional models, service models for
different applications and interactive processes and interfaces between the applications and
core protocol. Manufacturers may develop additional applications based these profiles. The
applications developed based on these profiles may interoperate with each other.
An IGRS remote media access profile is one of the IGRS RA application profiles. It is based
on the IGRS RA core protocol specified in ISO/IEC 14543-5-8:2017. All the basic access and
play control functions of media are based on the IGRS AV application profile specified in
ISO/IEC 14543-5-21:2012. ISO/IEC 14543-5-21:2012 specifies media server (MS) and media
client (MC) service functionalities of the AV profile. ISO/IEC 14543-5-6:2012 specifies the
service types and implementation methods in ISO/IEC 14543-5-21:2012.
This document specifies the service realization methods in an IGRS RA network, and clarifies
the differences between IGRS remote media access applications in an IGRS RA network and
IGRS media applications in a local IP network.
6 Application scenarios of remote media access
The possible application scenarios of IGRS RA media include the following.
a) Users can discover the local IGRS devices in a home network (TV, media player, set-top-
box, etc.) and the media content stored or played in these devices with the users’ remote
IGRS devices. Users can search the media content and control the rendering of the
content (i.e. play, stop, pause, continue, re-play, etc.).
b) Users can use the local IGRS devices (TV, media-player, set-top box
...
