Overview

ISO/IEC 14543-5-3:2012 defines the basic application framework for Intelligent Grouping and Resource Sharing (IGRS) within the Home Electronic System (HES) architecture for HES Class 2 and Class 3 devices. It specifies design criteria, application requirements, and interaction models enabled by IGRS application profiles to support media data streaming over wired or wireless home networks. The standard targets interoperability at the application level for devices such as media servers, media clients (TVs, set-top boxes), computers, household appliances and communication devices that implement digital media forwarding, storage and playback.

Key Topics and Requirements

• IGRS basic application framework: Defines a list of basic applications, operation details (device grouping, service description templates), function definitions and service invocation interfaces.
• Interaction model and conformance: Requires implementations to follow the IGRS interaction model and system design criteria described in Clause 5; conformance guidelines ensure consistent behavior among media clients, servers and recorders.
• Media forwarding, storage and playback: Describes media interaction flows and the required processes for streaming, storage and playback systems (Clause 6).
• Software and hardware interfaces: Specifies required or optional software profiles, invocation interfaces and hardware/network interfaces to enable interoperability (software profile, media formats, network interfaces, media client interfaces).
• IGRS components: Introduces concepts such as the IGRS Dynamic Service Invocation Module (IGRSDSIM), IGRS Services, Media Client (MC) and Media Server (MS).
• Protocol relationships: Aligns with IGRS Core Protocol (Part 5-1) which uses TCP/IP and HTTP as the message exchange framework and references application profiles (AV profile, File profile) for service-level behavior.
• Applicability: Applicable to devices implementing media streaming by wired or wireless means and intended as an implementation guideline to ensure application-level interoperability.

Practical Applications

• Enabling multi-room audio/video streaming and synchronized playback across grouped devices.
• Standardizing discovery, description and invocation of shareable media services in smart homes.
• Implementing media servers (NAS/PC) and media clients (smart TVs, set-top boxes) that interoperate across vendors.
• Supporting developers of home automation, consumer electronics and media applications to create IGRS-compliant products.

Who Should Use This Standard

• Firmware and application developers for consumer electronics, smart TVs, set‑top boxes and NAS devices.
• System integrators and product architects designing home media streaming and resource-sharing solutions.
• Test labs and QA teams validating conformance to IGRS basic application behavior.

Related Standards

• ISO/IEC 14543-5-1 (IGRS Core Protocol) - TCP/IP and HTTP framework

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:

– 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.
