Development
of Broadcasting and Telecommunication Convergence Framework
based on MPEG-21 (MPEG-21 ±â¹Ý ¹æ¼Û¡¤Åë½Å À¶ÇÕ ÇÁ·¹ÀÓ¿öÅ© ±â¼ú °³¹ß) |

MPEG-21 Multimedia Framework aims at defining a normative
open framework for multimedia delivery and consumption for use
by all the players in the delivery and consumption chain. This
open framework will provide content creators, producers, distributors
and service providers with equal opportunities in the MPEG-21.
The vision for MPEG-21 is to define a multimedia framework to
enable transparent and augmented use of multimedia resources
across a wide range of networks and devices used by different
communities.
The scope of MPEG-21 could be described as the integration
of the critical technologies enabling transparent and augmented
use of multimedia resources across a wide range of networks
and devices to support functions such as: content creation,
content production, content distribution, content consumption
and usage, content packaging, intellectual property management
and protection, content identification and description, financial
management, user privacy, terminals and network resource abstraction,
content representation and event reporting.
In this project, we develop the framework of MPEG-21. So
we make Digital Item using Digital Item Generator and parse
DID, DII, IPMP, MPEG-7, REL and so on based on Digital Item
Processing(DIP). |

Figure 1. An
Exemplary Digital Item |
|
Figure 1 indicates
the exam of Digitl Item. Digital Item used in MPEG-21 Framework
is declared by Digital Item Declaration Models such as Container,
Descriptor, Item, Component, Resource and so on. And upper example
is Digital Item which have two item, each Item includes two
Component. In short, this Digital Item related to a World-cup
image and a audio. |

Working Flow in each Platform |

As shown Figure 2,
Digital Item is manipulated, used based on DIP architecture.
The left-deshlLeft dashed-line indicate interaction between
the MPEG-21 terminal and a DI that arrived at this terminal.
Right dashed-line is interaction between a User and MPEG-21
terminal. And Full-line arrow indicate interaction inside the
MPEG-21 terminal. The DIM Engine can be seen as a central point
each part of MPEG-21 communicates using DIM engine. |

Figure
3. Overview of MPEG-21 TestBed Implementation |
|
In Figure 3,
each part of MPEG-21 communicates using DIM engine. Through
GUI module and Message Interface, user can use Digital Item
in which DIMs are defined. And DIM(offers to user many methods
to manipulate, consume and use Digital Item) is defined by DIBO(Digital
Item Base Operations) and DIxO(Digital Item extensible Operations).

Figure 4 show
us interface of Digital Item Processing. Based on DIP architecture,
all Digital Item can be rendered and user can be use Digital
Item through DIM List. |
