ISO/IEC 14543-5-5:2012 情報技術—家庭用電子システム（HES）アーキテクチャ—パート5-5：HES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—デバイスタイプ | 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. 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 in a logical group through the device group management mechanism in the IGRS specification

Note 1 to entry: Each IGRS device that joins 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

device type

identifier that indicates the physical and functional characteristic shown by an IGRS device

3.1.7

entity device type

identifier that indicates the physical form of a device

3.1.8

functional device type

identifier that indicates the functional characteristic of a device

3.1.9

IGRS client

application that draws upon the services of one or more connected IGRS devices

Note 1 to entry: Multiple client instances can exist on a network at the same time.

3.1.10

IGRS device

information device that conforms to the IGRS specification

3.1.11

IGRS dynamic service invocation module

part of the AV application logic to orchestrate the interaction of application services with respect to the capability of the device or device group involved and to coordinate the service invocation sequence between the media server and media client

Note 1 to entry: The IGRS dynamic service invocation module should be implemented on a media server, a media client or a separate other device.

3.1.12

IGRS service

shareable 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.

3.1.13

IGRS user

owner of an IGRS device and client

3.1.14

mandatory interface

service interface that is implemented by an IGRS device of some functional device type

3.1.15

peer-to-peer device group

set of IGRS devices where each IGRS device within a set has a peer-to-peer relationship to one another

3.1.16

service identifier

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

Note 1 to entry: 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.

3.1.17

service type

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

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

3.1.18

subservice

specific set of services that is a part of some functional device type

3.1.19

user identifier

identifier of an IGRS user
