Recent activation of DMB has enabled various high quality video, audio and data services. And there are various user facilities functions using digital data transmission. One of the various user facilities functions is EPG(Electronic Program Guide). EPG supports schedule of programs on screen for. audiences. EPG is composed to time, title, channel, genre etc. Users can select a program what they want to browsing. Currently EPG services are displaying program schedule on screen visually and make users to input ke:ywords with keypads, remote control devices or touch screen etc. However, this approach could cause a serious restriction to some users like to drivers or visually handicapped persons. A standard for a voice EPG to T-DMB is proposed. This method must be transferred VoiceXML based EPG files from the transmitter to receivers. This approach has a problem to process a standardization because the transmitter and receivers should be modified. We proposed and implemented a voice EPG platform that generates the voice EPG files from T-DMB SI without transferring voice EPG file from the transmitter.

With the start of digital broadcasting, TV screen, there is provided a new broadcast service is called EPG (Electronic Program Guide) that can be retrieved directly to a channel or program. However, a study considering the EPG of the user interface on the viewer position is so far insufficient. TV is because everyone watching the media, rather than a specific layer is necessary in order to find easy, intuitive user interface for the program to the viewer. That is, it is possible to quickly find the program to select the attributes that the TV viewer can be easily understood by using the EPG. To this end, this paper first genres which are representative of the properties that distinguish a TV program, time, rating, etc. were systematically classified. So viewers the values of the properties but to specify organized by the EPG, the order of attributes that specify the value we design a user interface that can be selected as having easy. And compare the superiority of the function evaluation of the two through the EPG in the EPG Usability Test proposed by the EPG with the existing commercial paper.

This study is about the TV Electronic Program Guide (EPG) design to which Perceived Information Architecture (PIA) based on user-experience is applied. The function-oriented information architecture is not friendly for user to search channels, while Multi-channels of EPG system provides users with opportunities to select a variety of channels. Because the menu structure of EPG user interface system is not compatible with the user experience. Therefore, this study presented a user-experience-based methodology and proposed a new solution for the information architecture of user-centered EPG system design.

DMB(Digital Multimedia Broadcasting)란 CD수준의 음질과 데이터 또는 영상 서비스 등이 가능하고 우수한 고정 및 이동 수신 품질을 제공하는 디지털 방식의 멀티미디어 방송이다. DMB는 서비스 방식에 따라 위성DMB와 지상파DMB로 나누어지며, 영상 및 음성 서비스에 데이터 신호를 동기화 시켜 데이터 서비스 또한 가능하다. 지상파DMB 데이터 서비스중 EPG(Electronic Program Guide) 서비스는 시청자가 현재 시청 중인 채널의 프로그램 편성 정보를 사용자에게 정의한다. 그러나 DMB 사업자 간의 이해관계 등으로 인해 시청자가 타 채널 편성정보를 확인하기 위해선 채널을 변경(Tunning)해야 하는 불편함이 있다. 이를 해결하기 위해 본 논문에서는 BWS(Broadcast Web Site) 표준과 리턴패스(Return Path)를 이용하여 지상파DMB의 EPG에서 확장된 개념인 XPG(eXtended Program Guide)를 제안하고 구현하였다. 이를 위해 2장에서 지상파 DMB의 각종 데이터서비스 표준 및 리턴패스(Return Path)를 분석하였으며, 3장에선 XPG 서비스를 제공하기 위한 XPG 서비스 시스템을 설계하고, 이를 위한 XPG 애플리케이션을 설계 및 구현하고 그 결과를 나타내었다.

본 논문의 목적은 Electronic Program Guide(EPG)용 응용프로그램을 위한 Application Program Interface(API) 및 이를 위한 Middleware의 구현이다. 이를 위해 Windows 환경 하에서 프로그램 정보 전송 프로토콜인 Program and System Information Protocol(PSIP)을 해석하는 Parser를 구현하고, 해석한 자료를 저장하는 Database를 설계하였다. 구현된 프로그램의 테스트를 위해 디지털 방송 수신 카드를 사용한 테스트베드를 구축하였고, 지상파 디지털 방송에서 수신된 MPEG-2 Transport Stream을 사용하여 구현된 시스템을 검증하였다. 본 논문에서 개발된 Middleware는 EPG를 위한 응용프로그램 및 향후 예약시청, 예약녹화 등의 부가 서비스를 위해 활용될 수 있다.

DAB(Digital Audio Broadcasting) is a new media service that can provide CD quality audio, various data service, interactive and high quality mobile communications through popular media such as terrestrial broadcasting, satellite, cable TV, and internet. In this paper, a new EPG(Electronic Program Guide) application model is proposed. The model is based on DAB and combines a DAB receiver and PCs so that it can take advantages of using various multimedia services and plenty of internet contents. The developed EPSD(EPG Provider System on DAB) has Web-based Server/Client structure and povides EPG functionalities to client PCs over internet. Therefore, the DAB receiver can be smaller and cheaper, and can develop abundant data services on internet. It can also provide high quality video services and be expected to become an important component in future home network systems.

EPG (Electronic Program Guide), which shows the title, broadcasting time, genre, parental rating of a program, is recognized as one of the most successful data service by viewers and broadcasting stations, who want an improved TV watching experience and a more fruitful profit model, respectively. In the circumstance, the request for the development or renewal of EPG frequently occurs and so the developers are looking for ways to improve the efficiency of the EPG development. This paper addresses the need of the developers by devising an EPG feature model based on FODA (Feature-Oriented Domain Analysis) and the testcases of each feature of the model. By utilizing the EPG feature model and the testcases, the tasks of requirement analysing and testcase designing, which are major tasks of the EPG development process, can be improved.

The progression of broadcasting technology changed the previous analogue broadcasting system into digital, which in result allowed several broadcasting programs to be transmitted as one stream by multiplexing. This multi channel environment interferes with audience to choose the program they want. EPG acts as supporter in this multi channel environment. The existing EPG system is limited in providing searching function with title, genre, date and Wish-list in multi-media environment. Thus, this thesis proposes new type EPG using PSIP information modification to respond with the change of broadcasting market. This type of EPG can be applied to several kinds of broadcasting systems.

With the emergence of digital TV broadcasting, various channels are provided to a TV audience. But it is getting hard for the audience to find his or her preferred TV programs due to the huge number of TV channels. In order to mitigate the difficulty, TV broadcasting companies provide an electronic program guide (EPG), which is a digital guide to scheduled broadcast TV programs. However, it results in the information overload problem and the time-consuming problem since the number of TV channels and programs is gradually on the increase. In this paper, we design and develop a channel filtering system, which recommends a small number of channels by filtering TV channels based on the watching pattern of the TV audience. The channel filtering system does not require the replacement or upgrade of existing TV or set-top box. In addition, it increases usability by skipping the channels that broadcast the audience's non-preferred TV programs while the TV audience presses the channel up/down button.

With the development of broadcasting technology from analogue to interactive digital, the number of TV channels and contents provided to audience is increasing in a rapid speed. In this multi-media and multi-channel world, it is difficult to adapt to the increase of TV channel numbers and their contents merely using remote controller to search channels. Due to this reason, EPG (Electronic Program Guide) has been one of the essential services providing convenience to audience. So EPG complying with European DVB-MHP specifications, which will be also our domestic standard, is proposed in this paper. In order to provide audiences with DiTV contents they preferred, we apply collaborative filtering algorithm to recommend contents according to preference value of audience group with similar preference. And we use JavaXlet application which is based on MHP to implement this EPG, while the result can be verified by OpenMHP emulator.
