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.

In the information society, individual, enterprise and nation must be equipped with environmment and competence with which they can acquire useful information anytime and anywhere to process and utilize it in required form. Therefore, this study intends to investigate how digital TV, refrigerator and computer are laid out in the residential space in terms of life space, analyze the preference of residents an d forecast the preferred functions of the products to be introduced in the future. To build frame for making questionnaire tool of this survey, 3 households of the first constructor among the top-ranked constructors in the first half of 2004 were chose and in-depth interview was made from April 12 to April 17. On the basis of result of preliminary survey obtained by this process, the questionnaire was revised and supplemented. Targeting those living at the apartment house in Seoul and constructors ranked in top-four in the order of construction of the first half of 2004, I selected 3 households for each group in the range of 30$^{\sim}$40 pyung. Twelve cases were surveyed from April 19, 2004 to June 5, 2004. First, TV will continue playing the role of central entertainment mustering family at one place rather than separating them to each room. Second, in the case of refrigerator, the function is being subdivided, making 2 types, refrigerator and kimchi refrigerator indispensable, which was in just unit in the past Third, while computer was usually placed in the individual bedroom,

One of the most typical examples of convergence is IPTV, a convergence of broadcast and telecommunication. Demand for IPTV has been increased so rapidly that a new TV set, called a smart TV, has appeared. One of the most important factors for IPTV business success is content. If an IPTV station provides popular content and subscribers can conveniently watch it then the station has a good chance of success. Therefore, the content management module is extremely important component of IPTV systems. In the current IPTV systems, operators must be present at the office to access a Content Management System(CMS). We implement a web CMS so that the operators can access the CMS anytime and anywhere as long as they are connected to Internet.

Digital Contents Services based on Internet are developing into an ubiquitous television that allows subscribers to be able to enjoy digital contents anytime and anywhere However, illegal copies and distributions of digital contents are also increasing proportionally. To guarantee the stability of contents service, many technologies are being developed and installed. The efficient scheme to manage content encryption keys is one of them. In this paper, we propose an improved key management scheme to manage the members of groups. The proposed scheme has a minimized transmission overhead for batch operation to renew content encryption keys.

A DMB in an ubiquitous age means that every one can share informations anytime anywhere through 'his own TV' or 'TV in his own hands'. A DMB of digital broadcastings makes the most use of informations through ubiquitous. But it has several problems just owing to retransferring existing broadcast programs in contents. So hereafter, DMB broadcasting must be produced with contents suiting its properties. After all, it is important to analyze exactly properties and service fields of medium of DMB to make an establish production direction of its contents. This paper analyzes such properties and presents overall image-contents production direction. This includes appropriate program developments and visual expressions through proper running time, camera angle and walking. The contents harmonized with its properties will give more familiarities to DMB users and it will be a new culture. In the end, it is expected that a share of DMB audience will be more higher.

With the rapid increase of recent smart phone diffusion, the convergences of home network environments and intelligent home appliances such as digital TV, internet refrigerator, DVD, digital video, communication appliance using a smart phone are highly focussed and become the recent trends in IT industry. In this paper, we design and implement home appliance control system based on the smart phone(Android) network environments. Through several experiments using Android smart phone, we confirmed that the proposed system can control and monitor indoor home appliances conveniently anywhere and anytime from outdoor.

This paper proposes a mobile content curation service to collect various online/offline publications. The company publishes one-time topic information to a broker server in advance and customer curates topic information on a mobile device by requesting it. The main characteristics of the proposed service are: it is based on request/response model rather than existing publish/subscribe model, can easily specify topic information by input string without QR code or audio recognition, and retrieves all of topic information anywhere anytime by storing it on mobile device. This service can be used for second screen campaign for TV and various online/offline events.

스마트 TV 및 스마트 셋톱박스와 같은 가정내의 고정형 스마트 기기에 대한 관심이 증가하고 있으며, 이러한 기기는 가정의 미디어 서비스를 제어하는 콘텐츠 허브로 발전하고 있으며, 홈 플랫폼의 포괄적 개념으로 정의할 수 있다. 이러한 홈 플랫폼은 IPTV, 지상파, 케이블, 및 위성 등의 다양한 방송 콘텐츠를 수용할 수 있으며, 모바일 단말 등의 외부 기기와의 연동을 통해 다양한 형태의 콘텐츠에 대해서 접근이 가능하다. 이와 관련하여 실제 서비스 제공이 가능한 기술은 방송 콘텐츠와 시간적으로 연계된 부가정보를 사용자의 모바일 단말에서 제공해 주는 서비스 기술이다. 또, 가정내의 홈 플랫폼을 통해 접근 가능한 다양한 방송 및 콘텐츠 부가정보를 통합적으로 취합하여 하나의 콘텐츠 가이드를 생성하고, 이를 개인 모바일 단말로 전송하여 사용자의 콘텐츠 소비 만족도를 보다 향상할 수 있는 기술에 대한 관심 역시 증가하고 있다. 본 논문에서는 홈 플랫폼에서 방송 수신 정보, 로컬 콘텐츠 및 모바일 단말의 저장 콘텐츠 정보를 기반으로 부가정보를 정합하여 ECG를 생성하고, 이를 모바일 단말에 전송하여 콘텐츠 서비스를 제공하는 플랫폼을 설계하고, 구현하였다. 통합 ECG 생성을 위한 콘텐츠의 메타데이터는 TV-Anytime 표준을 기반으로 적용되어 플랫폼간 상호 연동성이 확보되도록 하였다.

디지털 방송과 함께 저장매체를 갖는 PVR과 셋탑박스가 출현하였지만 방대한 컨텐츠에 대한 선택의 어려움이 발생하였다. 이러한 문제를 해결하기 위해서 PVR에서는 TV-Anytime과 MPEG-7 표준을 기반으로 멀티미디어 데이터에 대한 메타데이터를 제공한다. 이 메타데이터는 멀티미디어 데이터를 표현하는 특징적인 정보를 포함하고 있어, 컨텐츠에 대한 선택과 검색을 돕는다. 그러나 메타데이터는 그 내용이 방대한 XML document로 구성되어 있어, 효율적이고 빠른 검색이 쉽지 않다. 본 논문은 이러한 XML 메타데이터의 특성을 기반으로 효율적인 검색을 위한 XML 메타데이터 엔진을 설계한다. 제안하는 XML 메타데이터 엔진은 메타데이터의 정보적 특성을 기반으로 인덱싱 구조를 설계하여 XML 메타데이터의 접근 시간을 최소화한다.
