The development of the latest emotional recognition and multimedia technology has changed the traditional broadcasting system. The previous broadcasting system, which was operated by the terrestrial broadcasters, is now transformed to the viewer-centered and bidirectional broadcasting through the convergence of internet, mobile and smart TV. In this paper, smart-phone application for estimating human emotion(sadness, anger, depression) has been developed and emerged with smart TV, thereby we can present broadcasting service for enhancing the sense of common humanity among people of same group. If there is friend in the depression, we can bring comfort to him by inviting one for TV program what I watch and having a honest talk with facial avatar or emoticon. The proposed emotional broadcasting service inter-working with smart-phone application can give feeling of belonging and happiness to the people suffering from the blues, and it can prevent him from attempting suicide. In addition, smart-phone based emotional broadcasting service can be expended to program recommendation service customized to user's emotion, emotional LED lighting service to maximize the sense of reality and home shopping service taking advantage of the mood of customer.

The interactive advertisement is already on satellite and cable broadcasting hereafter the introduction of this system is concerned on terrestrial programs. This study is to research the effectiveness of interactive TV advertising focusing on factors of involvement and interaction. Study started for the effect measurement of interactive television advertisement. Interactive television advertisement has different concept than existing television advertisement. Thus, the effect also needs to examine in other methods. Study is mainly focusing on the characteristics of interactive and the experiments, which was based on existing data, for measurement of effect. In the experiments, the characteristics were categorized in a search time, a number of searched pages about interactive television advertisement. The research finds that the involvement of the audience increases when the interaction of advertising attitude, brand attitude, and purchase intentions also increases. And so, a successful interactive TV advertisement results in longer searching hours and greater it visits by the audience when the interaction factors are considered and increased. By study of consumer's characteristics and behavior, a new method of the effect measurement for interactive television advertisement is provided. The new method includes not only existing measurement elements of television advertisement which are attitude on advertising and brand, and customers' purpose, but also the features of interactive television advertisement, which are search time, a number of searched pages. Recently added features provides data of the effect on high/low groups and it contributes to the process of interactive television advertisement. Study on interactive television advertisement will be helpful to plan an effective strategy by suggesting the theoretical evidence of its effect.

This study is about the interactive self-portrait which provides the experience of self-consciousness reflection of the viewer to modern people who are easily alienated in rapid social change. We proposed interactive self-portrait is implemented by an interactive mirror that reproduces the appearance of the viewer acquired using a webcam. The interactive mirror, which can directly project its own image, is drawn by searching news articles in real time and using the extracted characters as pixel information in real time. The viewer has the opportunity to experience a new style of active self-expression while watching his/herself composed of news characters that are issues of modern society. The virtual self-portrait designed with news characters can attract viewers' attention by visually expressing the interests of modern people and can act as an incentive to generate positive interaction.

Traditional broadcasting environment is merged with various interactive broadcasting services, and the users use these services through Set-Top-Boxes. But they have limited user interfaces, which are not suitable for TV environments by adopting internet formats. Therefore, this paper suggests a User Navigating Interface which helps the audiences to select and watch their favorite channels more effectively. Firstly, this paper analyzes EPG interface - the most basic service in interactive broadcasting. Secondly, it suggests a user interface and service structure suitable in the network-integrated TV environment.

Interactive broadcasting service using wired/wireless Internet return channel has strong ripple effect. It allows the audiences to participate actively to the program they are watching, and communicating. This paper develops an authoring tool that makes an object-formed interactive advertisement from extracted areas of the advertising object the user specified in TV programs. In the authoring tool, the advertisement producer specifies the target object subjectively and the selected object keeps moving here and there repeatedly. Therefore, it is hard to make an object-formed interactive advertisement with existing tools. This paper suggests sketch-based interface technique for extracting advertising objects, and also provide evaluation functions to correct any sketch error. This paper also converts the area of object into MPEG-4 BIFS codes for authoring the object-formed interactive advertisement.

In general, under interactive broadcasting environment, user finds additional service using top-down menu. However, user can't know that additional service provides information until retrieval has finished and top-down menu requires multi-level retrieval. This paper proposes the new method for additional service providing not using top-down menu but using object selection. For the purpose of this method, the movie of a MPEG should be synchronized with the object information(position, size, shape) and object tracking technique is required. Synchronization technique uses the Directshow provided by the Microsoft. Object tracking techniques use a motion-based tracking and a model-based tracking together. We divide object into two parts. One is face and the other is substance. Face tracking uses model-based tracking and Substance uses motion-based tracking base on the block matching algorithm. To improve precise tracking, motion-based tracking apply the temporal prediction search algorithm and model-based tracking apply the face model which merge ellipse model and color model.

Despite the fact that the mobile environment has favorable conditions for using data contents, it is not easy to implement enhanced data services for mobile broadcasting based on MPEG-4 BIFS. With a structure inherited from VRML, BIFS targets different types of content with a development approach that is not very compatible with broadcasting contents. Furthermore, it is not easy to implement BIFS because the standard is too complicated for the mobile broadcasting environment. Accordingly, this study proposes an enhanced mobile TV contents model that provides interactive 3D objects and GUI for the viewers to interact with the broadcasting contents. By applying the model to the DMB environment, this study suggests a direction for future developments of mobile broadcasting contents. In order to represent 3D graphics on mobile TV, we analyzed MPEG-BIFS 3D nodes and composed a subset of VRML profile, and defined new nodes that can efficiently represent GUI at the content development level. If this study helps facilitate expression of 3D graphics and interactions in data contents composition, enhanced efficiency of contents development is expected to promote the development of various contents suitable for the mobile broadcasting environment.
