ISO/IEC 14543-5-1:2010 情報技術—家庭用電子システム（HES）アーキテクチャ—パート5-1：クラス2およびクラス3のインテリジェントなグループ化とリソース共有—コアプロトコル | ページ 6

3.1.1

centralised device group

set of IGRS Devices with one IGRS Device acting as the master

Note 1 to entry: The master is responsible for managing the setup, for dismissing a Device Group, and for processing a join request from other devices.

Note 2 to entry: The master device and other IGRS Devices in such a Device Group form a centralised or master-slave relationship.

3.1.2

client identifier

unique identifier associated with a Client on an IGRS Device to which that Client belongs

3.1.3

device group

multiple IGRS Devices that are organised into a logical group through the device group management mechanism in the IGRS specification

Note 1 to entry: Each IGRS Device in a Device Group follows common interaction rules. Two types of Device Groups are defined: peer-to-peer Device Group and centralised (master-slave) Device Group.

3.1.4

device identifier

globally unique device identifier associated with one IGRS Device

3.1.5

device pipe

channel used to transfer device interaction messages

Note 1 to entry: This channel is set up through the pipe setup mechanism in the IGRS Specification.

3.1.6

IGRS client

application that draws upon the services of one or more connected IGRS Devices NOTE Multiple client instances can exist on a network at the same time.

3.1.7

IGRS device

information device that conforms to the IGRS specification

3.1.8

IGRS service

sharable resource encapsulated in an IGRS Device by implementing application interfaces and providing services for other IGRS Devices

Note 1 to entry: An IGRS Service has an invocation interface that meets the requirements of the IGRS specification. These invocation interfaces are described and announced on the network through the IGRS Service Description Specification.

3.1.9

IGRS specification

ISO/IEC 14543-5 series of standards

3.1.10

IGRS user

owner of an IGRS Device and Client

3.1.11

peer-to-peer device group

set of IGRS Devices where each IGRS Device in this set has a peer-to-peer relationship with each other

3.1.12

service identifier

unique identifier assigned to a service provided by a specific IGRS Device

Note 1 to entry: Note that the same type of service may be provided by multiple IGRS Devices within the same network. Each instance of a service has a unique service identifier on the IGRS Device providing that service.

3.1.13

service type

category of IGRS Service defined according to the set of resources encapsulated

Note 1 to entry: The Service Type enables service applications in the same category to have common invocation interfaces.

3.1.14

user identifier

identifier of an IGRS user
