This study explored effect of shotsize and concern on the elector's attitude. For this study, 2 different styles of TV address moving pictures were produced on the basis of TV address text of district leader candidate. They were exposed to two different groups composed of university students, and the degree of favor, confidence and support was measured and analysed. The result of this study showed that the group exposed to bust shot was more favorable and supportive than the group exposed to waist shot. However, interaction effect between shot size and concern was not found. The meaning of this study can be found in the fact that effect of shot size as an element of non-verbal communication on the politician's image was proved through experiment.

In this paper, I am going to analyze a commercial film narrative focused on a temporal order through the theory of narrative discourse by Gerard Genette. Advertisements has a special quality or feature to be convertible into mythological hyper reality to advertise an product effectively. In this process, narrative in a commercial film has visual variations using a temporal order to show an glamorously advertisements in television. The reason that narrative in a commercial film is subject to variation with a temporal order, duration, frequency is to get some aesthetic effect for making sure people see them. Under the influence of postmodernism, image making like a pop-art became the first consideration in a commercial film with the consequence that representation as a signifier came to be more important than object as a signified. As a commercial film have more sensational image as a result of visual variation, images in a commercial film became vague so that it does not explain or express an advertising concept dearly. However, those aspects have assets that it gives the TV audience a room for interpretation in advertisements by themselves.

This paper presents a localization perception of a phantom sound image for ultrahigh-definition TV with respect to various loudspeaker configurations; two-horizontal, two-vertical and triplet loudspeakers. Vector base amplitude panning algorithm with modification for non-equidistant loudspeaker setup is applied to create the phantom sound image. In order to practically study the localization performance in real situation, the listening tests were conducted at the on-axis and off-axis positions of TV in normal listening room. A method of adjustment which can reduce the ambiguity of a perceived angle is exploited to evaluate the angles of octave-band signals. The subjects changed the panning angle until the real sound source and virtually panned source were coincident. A spatial blurring can be measured by examining the differences of the panning angles perceived with respect to each band. The listening tests show that the triplet panning method has better performance than vertical panning in view of perceptual localization and spatial blurring at both on-axis and off-axis positions.

Many signal processing methods of widening the sound image for spatial impression have been studied. Most typical methods of widening the sound image are related to the phase shifting and precedence effect. However, these methods are not effective in center sound image. As listener's position moves from center to outside, the center sound image is shifted to the speaker. That is to say, the directional localization of center sound image is unstable. In this paper, we propose a television audio system including center speaker, and analyze the role of center speaker using theory of Makida and precedence effect. In experiments, we confirm the usefulness of the center speaker for the stability of center sound image.

To create a more realistic soccer game derived from TV images, we are developing an image synthesis system that generates 3D image sequence from TV images. We propose the method for the team and the pose recognition of players in TV images. The representation includes camera calibration method, team recognition method and pose recognition method. To find the location of a player on the field, a field model is constructed and a player's field position is transformed by 4-feature points. To recognize the team information of players, we compute RGB mean values and standard deviations of a player in TV images. Finally, to recognize pose of a player, this system computes the velocity and the ratio of player(height/width). Experimental results are included to evaluate the performance of the team and the pose recognition.

TV technology started from black and white TV. Color TV invented and users request more realistic TV technology. The next technology is 3DTV. For 3DTV, 3D display technology, 3D coding technology, digital mux/demux technology in broadcast and 3D video acquisition are needed. Moreover, Almost every contents now exist are 2D contents. It causes necessity to convert from 2D to 3D. This article describes 2D/3D conversion algorithm and H/W platform on FPGA board. Time difference makes 3D effect and convolution filter increased the effect. Distorted image and original image give 3D effect. The algorithm is shown on 3D display. The display device shows 3D effect by parallax barrier method and has FPGA board.

TV broadcast of election returns is an index to measure a public responsibility, scientific analysis and production power in each broadcasting station. This is the reason why each broadcasting station is spending a great amount of money, mobilizing many people and using facilities. TV election returns broadcast has been advanced for decades, particularly in its production, system and presentation. And, among those, broadcast graphic and inset graphic, which are representing election-related information, have became the important components in TV broadcast of election returns because of the advancement of production technology, a variety of presentation forms, and the visual effects. In this research, I analyze the part of image composition in inset graphic of TV election returns broadcast. As a result, in making insert graphic, each broadcasting station is analyzed to be producing the accurate and clear delivery of information on the stability and reliability of a visualized form, first and foremost. It requires that we research the methodology for the accurate and reliable delivery of information, as well as various image productions with a result of the progress in production technology.

Among single image SR techniques, the TV based SR approach seems most successful in terms of edge preservation and no artifacts. But, this approach achieves insufficient SR for texture component. In this paper, we proposed a new TV-G decomposition based SR method to solve this problem. We proposed the SVR based up-sampling to get better edge preservation in the structure component. The NNE used the relaxed constraint to improve the NE. We used the NNE based learning method to improve the resolution of the texture component. Through experimental results, we quantitatively and qualitatively confirm the improved results of the proposed SR method when comparing with conventional interpolation method, ScSR, TV and NNE.

This study examined the degree to which integrated marketing communication(IMC) might be manifested in South Korean television advertising. Using a framework by Nowak and Phelps(1994), this study investigated the degree of IMC utilization by service organizations and physical goods manufacturers at the advertisement level. The Result showed that 44.6% of the television ads were classified as integrated marketing communication according to criteria discussed by Nowak and Phelps(1994). More specifically, approximately 90.7% of the integrated ads achieved this status by using two communication tools of different orientations. In addition, the most common form of IMC at this lowest level consisted of an image-oriented(brand advertising) and a behavior-oriented(direct response) communication tool. The second common form of IMC, that is, 9.3%, used three different communication tools; they consisted of an image-oriented tool(brand advertising) and the two behavior-oriented(i.e., direct response and sales promotion) communication tools. Nothing of the magazine ads used all four tools. Thus, South Korean television ads exhibited higher degrees of IMC which tended to include more behavior-oriented communication tools than image-oriented communication tools. These results indicate that much higher chances for advertisers to expand the level of IMC will be existed. Furthermore, the results suggest that significantly higher as well as a wider variety of communication tools are being used by advertisers, considering the limit of samples investigated in this research.
