4 Conformance
This International Standard is intended to be used primarily as an implementation guideline
for developers to ensure interoperability at the application level.
For conformance to this International Standard the following applies.
• The interaction model used in an IGRS media AV basic application shall meet the system
design criteria specified in Clause 5.
• The specific interaction flow process used in an IGRS basic application for digital media
forwarding, storage and playback system shall meet Clause 6.
• Media clients, media recorders and media servers shall be compliant with the relevant
protocols, function descriptions, software profiles, software interfaces (including media
format supported) and hardware interfaces (including physical and networking interfaces)

5 Overview
5.1 Summary
An IGRS application, based on the IGRS core protocol and IGRS application profiles, is
classified in two types: IGRS basic application and IGRS extended application. As defined in
ISO/IEC 14543-5-5, IGRS devices can be divided into many different device types according
to usage scenarios. An IGRS basic application, which is directly related to a specific device
type, is a standardized application defined by the IGRS specification that corresponds to a
particular IGRS device function. It is expected that a specific device type on an IGRS device
would result in a standardized IGRS basic application implementation. An IGRS extended
application may be developed by a third party supplier based on the IGRS core protocol and
IGRS application profile. An IGRS extended application conforms to the IGRS standard and is
intended to diversify and to enhance the current IGRS device functionalities.
The IGRS basic application defines application requirements enabled by the relevant
application profiles. It also defines the interaction process and interaction interfaces that may
or may not be specified by the existing application profiles related to these basic applications.
Application manufacturers are allowed to develop their own basic applications independently
based on this standard guideline. However, interoperability shall be achieved among these
various application implementations. Moreover, application manufacturers can also choose to
develop their own extended applications independently, as necessary.
The guidelines of this standard include the following basic applications based on the IGRS
core protocol and application profile:

---------------------- Page: 9 ----------------------
– 8 – 14543-5-3  ISO/IEC:2012(E)
• digital media forwarding,
• storage,
• a playback system.
This standard defines the application requirement, specific functional description, basic
service description, basic device description, software profile, software interface and
hardware interface for digital media forwarding, storage and a playback system.
5.2 Design criteria
5.2.1 Relationship between basic application and IGRS
The basic application includes two parts: one part specifies the application profile and the
interaction process of the IGRS basic application; the other specifies the functional definition,
interface invocation and service invocation message format of other software tools needed to
ensure interoperability and ease of use. An IGRS application is triggered through the
interactions between one or more IGRS services and one or more IGRS clients invoking IGRS
services. The basic application shall guide users to design integrated applications based on
IGRS protocols.
5.2.2 Relationship between basic application and transport protocol
The basic application does not rely on any specific transport protocols. Therefore, it shall
support any transport protocols such as FTP, HTTP, etc.
5.2.3 Relationship between basic application and existing file sharing system
The basic application defines a set of standard interfaces used in an IGRS network. It does
not pose any restriction on the back-end implementation method. Therefore, the file sharing
system associated with the IGRS basic application cannot only support a proprietary system
developed by users, but also any existing sharing system.
5.2.4 Relationship between basic application and file format
The basic application profile is independent of any specific file format, which means that it
shall support interactions with files of any arbitrary format.
5.2.5 Basic application interaction model
An IGRS application is achieved through interactions between one or more IGRS services and
one or more IGRS clients. Typically, the interaction of an IGRS application is as shown in
Figure 1.

The following guidelines shall apply.
a) The application scenario shall be clearly described. Through a description of application
scenarios, the users shall obtain valuable user experience information and learn about
reusable operational procedures.
b) Description of specific functions shall be accurate. By describing specific functions, users
shall know which IGRS device is used and what IGRS services and corresponding
interfaces have been invoked.

d) Description of the software profile shall give the users a clear blueprint of the basic
application design.
e) Description of the hardware interface shall be specific so that users shall achieve a
preliminary understanding about the hardware interface design requirements.
5.3 Explanation remarks
This standard presents a guideline for designing basic applications based on the IGRS
protocol. Other basic applications will be added in updated versions.
6 Digital media forwarding, storage and playback system
6.1 Overview
With recent advances in computer and networking technologies, massive amounts of digital
multimedia sources are emerging, such as large volumes of music in MP3 format, Internet
broadcasts and multimedia AV streams that are transmitted over a home network. The
introduction of digital technologies has enabled the multimedia sources to surpass the
capabilities of traditional multimedia technologies for content display, quality and upgrade
speed. Present home theaters based on traditional technology may not include features that
users expect as a result of developments in the Information Age, so new products are needed
to close the gap. Alternatively, new functionalities may be integrated into existing products to
provide additional features possibly at a lower cost.
Even the biggest PC screen cannot deliver the same visual effect as a TV. In addition, the
operation of a PC is still too complicated to be used in the living room compared with other
common electronic applicances such as the TV. Meanwhile, there is another problem: various
existing video-on-demand services and set-top-boxes can only implement a limited set of
functions. For example, existing boxes may not allow the TV to receive digital broadcasting
programs nor allow the user to request video programs via the Internet or log onto the Internet
via TV. Desired user features may be commercialized by working around various restrictions
posed by broadband operators and content providers.
Based on the state of the industry as described above, and the present technologies, any
single PC or CE (consumer electronics) device cannot provide a complete solution for
enabling household multimedia in the Digital Age. The digital media forwarding, storage and
playback system of this standard offers a specific solution to meet this demand by integrating
digitization and networking technologies into relevant TV and PC devices. It specifies a
multimedia system based on a digital home network concept that carries out a plethora of
multimedia functions in a home network setting. The entire system architecture design is
simple, easy to operate, convenient, individualized and easy to implement.
This application combines existing CE, PC, embedded systems, multimedia compression,
transmission technologies, as well as emerging Internet networking technologies. A PC
specializes in networking, storage, computing and personalised customization capabilities,
while a traditional home theater multimedia system is characterized by ease of operation as
well as a superior visual and audio experience for the home. By combining these two features,
one can establish a multimedia system platform suitable for the home. Specifically, by adding
a digital multimedia adaptor, this application closely ties the traditional PC and multimedia
devices together while taking advantage of the dedicated functions provided by each device.
experience in the home
This combination enables and extends the current digital multimedia
in a seamless way that is easy to operate.
A digital media forwarding, storage and playback system is mainly used in a home scenario
(see Figure 2 ). Among the devices in this scenario, the computer serves as the media server;
the set-top-box or TV with an embedded digital media-forwarding module serves as the media
client. The contents include videos, music and photos. This application enables auto-

discovery and connection with the computer, requiring no manual configuration. First, the user
installs a set-top-box called an “IGRS TV STB.” The IGRS TV set-top-box or an IGRS TV
module embedded in an IGRS TV can be used as a digital media adaptor to connect the
computer and IGRS TV through a wired or wireless network. This combination enables the
user to watch movies, listen to music and and view photos on the TV seamlessly with only a
few button clicks. The specific functions include media player and media recording, etc. After
the IGRS TV set-top-box discovers an IGRS computer, they exchange service messages
automatically in order to set up connections. The IGRS set-top-box or IGRS TV module
embedded in an IGRS TV shall support format transcoding to enable interoperability.
Meanwhile, this system can also compress TV programs captured by the modulator of a
digital multimedia recorder device i
