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
media access application shall conform to Clause 8.
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, etc.) in a home
network to detect IGRS RA devices and media content stored or being played in these
devices. Users can search the media content and control the rendering of the content
(i.e. play, stop, pause, continue, re-play, etc.).
c) When users are playing media content in an IGRS network, they can pause the play
functions and save the current play location with a bookmark. They can resume the play
functions from the paused location with another IGRS device.

7 Remote media access application system
7.1 Overview
In an IGRS remote media access application system, an RAMS is a media content storage
device. It grants the search and transfer rights to other devices. An RAMC is a device to
access the media content stored in an RAMS. It can browse, search, receive and render these
contents.
RAMS devices and RAMC devices in an IGRS media access application shall establish a
sibling relationship as described in 10.1 of ISO/IEC 14543-5-8:2017. Alternatively, the owner
of the RAMS shall authorize the access right of the RAMS to the owner of the RAMC through
the device access rights configuration mechanism described in Clause 9 of ISO/IEC 14543-5-
8:2017.
An IGRS remote media access profile is an extension of IGRS AV profiles specified in
ISO/IEC 14543-5-21:2012. It specifies an application profile for dedicated media access and
invocation functionalities based on the RA system architecture specified in Figure 1 of
ISO/IEC 14543-5-7:2015. The basic media invocation flow services shall follow
ISO/IEC 14543-5-21:2012 and ISO/IEC 14543-5-6:2012.
Figure 1 shows the interaction model of an IGRS remote media access application.

Figure 1 – Interaction model of IGRS RA media access application
The RAMS and RAMC are both IGRS RA devices that are connected to the IRSP and shall
follow ISO/IEC 14543-5-9:2017. Each of them shall comply with the lower layer of the IGRS-
RA core protocol specified in ISO/IEC 14543-5-8:2017 and the higher layer IGRS remote
media access profile specified in this document.
The transmitted data between a RAMS and RAMC primarily consist of control commands and
media data. The control commands include content indexing commands and media invocation
commands.
The content indexing commands are used by the RAMC to index the content in RAMS. The
media invocation commands are used by the RAMC to control the media content transfer of
the RAMS.
The media data are transferred between the RAMS and the RAMC according to the media
invocation commands.
7.2 IGRS RAMS
The IGRS RAMS is a device with an Internet connection, shall comply with the IGRS RA core
protocol of ISO/IEC 14543-5-8:2017, and has the capability of storing multimedia content,
accessing IRSP and transmitting multimedia content to an RAMC according to control
commands from the RAMC. The IGRS RAMS usually provides the managed content to an

---------------------- Page: 12 ----------------------
ISO/IEC 14543-5-101:2019 – 11 –
© ISO/IEC 2019
IGRS RAMC as the initiating device in media application. The IGRS RAMC could access,
manage and render this content through the IGRS-RA network. The IGRS RAMS could also
function as a target device of a media access application when the IGRS RAMC uploads
media contents to it.
Components of the IGRS RAMS are shown in Figure 2.

NOTE The block noted by a dashed line is optional.
Figure 2 – Components of IGRS RAMS
The IGRS RAMS shall comply with ISO/IEC 14543-5-8:2017 and shall provide services of a
content index service (CIS), connection management service (CMS), media server transport
management service (MSTMS) and optional media transcoding service (MTS).
The components of the RAMS are summarized in a) to d).
a) CIS: The IGRS RAMS shall support CIS so that an IGRS RAMC could browse, search and
access the stored contents. Through the description of content element data, CIS provides
the basic information to match the media format and transmission mechanism in the media
playback mode between an IGRS RAMS and IGRS RAMC. CIS also provides the
necessary supports for senior personality content management. The procedure calls for
CIS are specified in 8.1 of ISO/IEC 14543-5-6:2012.
b) CMS: An IGRS RAMS shall support a CMS to manage the connection between an IGRS
RAMS and an IGRS RAMC. The IGRS RAMS shall execute the interface function
GetProtocolInfo() of CMS, so that other devices in a network may query the media format
supported by the RAMS and get the connect management and transmit control mechanism
supported by the RAMS.
A CMS includes the following interface functions:
1) query RAMS supported media format;
2) get supported connect
