This paper shows the research about the personalized broadcasting system. The personalized broadcasting is the service that users only show the programs which they want to watch when they want to watch these. The purpose of the bi-directional broadcasting service is supporting more satisfied and more personalized services by permitting the bi-directional data transformation. This research also develops the user profiling system for the bi-directional and personalized broadcasting service. This system applied the TV-Anytime metadata specifications which is the standard for the personalized broadcasting services, the system supports the various functions for the bi-directionl and personalized broadcasting such as the user profiling, contents metadata and targeting advertisement services. The bi-directional and personalized broadcasting system increases the users' satisfaction with the recommendation and management of the personally favorite broadcasting contents and advertisements, the trial run results show that the services raise the users' satisfaction with the intelligent and discriminating broadcasting services.

Nowadays, as it goes on digitalization of the broadcasting and the convergence of the broadcasting and communications , it has been developed into the ubiquitous individual media consuming pattern which can easily and comfortably consume the favorite contents through any devices at anytime and/or anywhere. For this, in this paper, we propose personalized broadcasting service that can provide a convenient access of the contents that users want to watch at anytime by considering the user preference and consumption characteristics as well as an efficient browsing and watching of the particular program segments more advanced than the data broadcasting services. Moreover, it is implemented the TV-Anytime standard based on personalized broadcasting terminal platform by us. The developed services and terminal will used on broadcasting environment in which many services and the contents. The result of that is the broadcasters/service providers and content providers can provide differential broadcasting services which is suitable to each user such as personalized broadcasting service in near future.

As accelerates the technical evolution of high-speed network and progresses the digitalization of broadcasting network, TV channel service through satellite/cable/terrestrial networks becomes more stable and mature. However, TV channel service using IP network such as IPTV is recently emerging. Especially, when it comes to current mosaic EPG(Electronic Program Guide) as a channel guide, the implementation of EPG via IP network is under developing. Furthermore, the personal target mosaic EPG is not provided at all in the IPTV. This paper proposes a construction method of mosaic system which can support fixed and personalized mosaic EPG using IP network for viewers. The fixed mosaic EPG is made several steps as follows ; First, H/E generates several mosaic A/V streams. Then, which are transmitted to the STB in terms of multicasting via IP network. Finally, mosaic EPG is displayed on TV through STB. In addition, this paper describes a construction model of the personalized A/V mosaic EPG that represents each person's favorite channels according to their tastes and interests. As for the contributions. The TV channel guide using IP network enable viewer to select channel more easily with practical adaptation of multi-channel expansibility and sufficient usability. In addition, through personal mosaic EPG, a number of viewers can compose their own mosaic EPG and enjoy a variety of channel easily in accordance with their preferences. Finally, the personal mosaic EPG can prohibit non-adult users from connecting adult-only contents more efficiently.

In this paper we introduce a design and implementation of an agent for multimedia retrieval and personalized broadcasting service. It is compliant with TV Anytime Forum specifications and supports searching location resolving, storing and streaming of remote multimedia contents. For this service, we implemented a contents server, a 메타데이터 database server, a location resolution server and a client terminal is implemented The Client terminal gathers content information by SOAP of operation, and it has a user preference module and usage history module that make user information. The personalize service agent recommends suitable contents to user by similarity algorithm.

본 논문에서는 양방향환경에서의 메타데이터 서비스를 제공하는 TV-Anytime 시스템에서의 개인 맞춤형 서비스를 위한 오퍼레이션들을 설계 밋 구현한다. TV-Anytime 포럼에서는 양방향 환경에서의 메타데이터 서비스를 위해 get_Data 와 submit_Data 오퍼레이션을 정의 하였으나, 이 두 오퍼레이션은 양방향 환경에서의 맞춤형 서비스를 제공할 수가 없다. 이에 본 논문에서는 사용자 프로파일 정보를 활용한 개인 맞춤형 서비스를 위해 새로운 오퍼레이션을 제안한다. 제안된 오퍼레이션을 통해 사용자는 양방향 환경에서의 SOAP 프로토콜을 통해 콘텐츠의 검색, 저장, 탐색 및 개인 맞춤형 서비스가 가능하다.

The user-centric broadcasting environment includes the agent system and personalized broadcasting services for user-adaptive TV watching. In this paper, we propose broadcasting environment consisting of personalized broadcasting services and a multi-agent broadcasting system for the services. The proposed system employs the intelligent agent technology of the Foundation for Intelligent Physical Agents (FIPA) as well as metadata technology of MPEG-7 and TV-Anytime Forum (TVAF). To verify the usefulness of the proposed environment, we implemented a test-bed and demonstrated the proposed agent system with three services including intelligent user-information management service, information mobility service, and content retrieval service.

The personalized service becomes an important role in consuming the mobile broadcasting contents due to the lack of television watching time in the mobile environment. The paper discusses the technology development of ECG (electronic content guide) for personalized broadcasting service such as contents tracking, time shifting and contents scraping according to user preference.

Compared with analog broadcasting, digital broadcasting supports technical background to provide personalize the TV watching environment by offering broadcasting services that can adapt to viewers' preferences. However, current digital broadcasting shows limited services such as reservation recording, simple program guiding with an electronic program guide (EPG) on a personal video recorder system, and primitive data broadcasting by broadcasters. Therefore, the purpose of this paper is to suggest a new broadcasting environment which gives a person facility and a difference fur watching TV by serving enhanced personalized services. For that reason, we propose an intelligent broadcasting system which can minimize viewer's actions, and enhanced broadcasting services which are based on understanding of the semantics of broadcasting contents. To implement the system, agent technology as well as the MPEG-7 and TV-Anytime Forum (TVAF) are employed. For content-level services, real-time content filtering and personalized video skimming are designed and implemented. To verify the usefulness of the proposed system, we demonstrate it with a test-bed on which content-level personalized services are implemented.

In this paper, storing and removing method of broadcasting content is proposed for personalized consumption. The main objective of this paper is to keep personalized information, such as additional contents, user creation data, usage history, with broadcasting content, and user can consume broadcasting content to accommodate individual preference. Consequently, proposed file format in this paper is based on MPEG-4 and MPEG-21 file format because they can access and extract data within file format easily and can keep spatiotemporal relation between data. In addition, TV-Anytime metadata is used for program description metadata. Finally, proposed method is verified with file format player and useful application scenarios.

TV는 타 도메인과 달리, 사전에 정해진 시간에 콘텐츠가 방영된다. 그러므로 TV 프로그램 추천 시스템은 시청자의 현재 시각(time-context)을 고려해야 한다. 시간 기반의 TV 프로그램 추천 방법이 다수 연구되었지만, 대부분의 기존 연구는 특정 시간대(timeslot)에서의 시청자의 선호도를 계산하는 데에만 집중되어 있고, 시청 내역 전체기간에서의 선호도를 고려하지 않은 문제점이 있다. 이러한 문제를 해결하기 위해, 시청자의 지역 선호도와 전역 선호도를 모두 고려한 시간 기반의 TV 프로그램 추천기법을 제안한다. 이를 위해 제안 방법에서는 시간대의 길이에 따라 여러 가지 선호도 모델을 사용한다. 여러 개의 선호도 모델로부터 산출된 선호도를 병합하여 가장 선호도가 높은 TV 프로그램을 추천한다. 실 데이터를 이용한 실험을 통해 기준방식과 비교함으로써, 제안 방법의 효용성을 검증하였다.
