Overview of ARIB Standards (STD-B23)

1. Overview

Standard Name Application Execution Engine Platform for Digital Broadcasting
Enactment Date 06.05.2003
General Description

This standard, in the digital broadcasting performed in Japan, specities a data encoding method of application execution environment. It is composed of two parts of the mono-media encoding method and the application execution environment. The mono-media coding system, get an adjustment with BS and CS digital broadcasting system has been already in practical use in Japan, and the application execution environment gets an adjustment with the network utilization and application execution environment in Europe and United States. Add the required provisions of the domestic broadcast based on the MHP system of the European DVB and its international use policy GEM (Globally Executable MHP). This standard is basically a cross-sectoral manner applicable in all broadcast media, it has been defined as operating restrictions on broadcast media specific conditions determined from the transmission system and the service request.


Keyword Description
Mono-media Video, still images, graphics, sound, single representation media such as characters. Presentable representation media only in its own data without reference to other media.
DVB Abbreviation of Digital Video Broadcasting
GEM Abbreviation of Globally Executable MHP
MHP Abbreviation of Multimedia Home Platform
ARIB-J An application execution environment to be defined in this standard is referred to as ARIB-J. ARIB-J is extending the GEM1.0 and to be defined.
Application Units of content constituting the data broadcast service to be executed by the virtual machine on the receiver.
GEM application

The application is defined as "GEM Application" in GEM1.0.

GEM application operates properly on ARIB-J.

ARIB-J Application Add the provisions of this standard on the GEM application, extended application.
ARIB-SI   To distinguish it from SI the DVB is defined, the program sequence information specified in ARIB STD-B10 is defined as the ARIB-SI.

Abbreviation of Application Information Table

Application information table. Including data for transmitting the additional application information for identifying and controlling an application.

Event A collection of broadcasting data stream components have been established that start and end time belonging to the same service, it refers to one of the program, such as news, drama.
Event (Described in javadoc) java.util.EventObject class and its subclasses, generic name of those instances. In addition, the events that cause the occurrence of the object.
Virtual machine Defined computing device is not dependent on a specific software or hardware.
