The purpose of this study is to verify the factors that have the impact on Vietnamese female consumers' attitude towards PPL and purchase intention on products in K-Drama. Additionally, the current study aims to discover the moderating effect of usual perception on PPL and the effect of usual flow level on the effects of PPL informativeness and intrusiveness. The existing PPL related research have focused on the effect of the domestic contents on the domestic consumer. However, it is significant that this study examines the impacts of domestic contents on foreign audience' purchase intentions on advertised products. The empirical results are as follows. First, informativeness has positive impacts on attitudes towards PPL and purchase intentions on products. Second, intrusiveness has negative impacts on the outcome variables. Third, attitudes towards PPL shows positive effect on purchase intentions on products. Lastly, the research revealed some interesting evidences on the moderating effects of usual perception on PPL and usual flow level on the main effects.

최근 다양한 실감 미디어 기술과 표출 방법이 제시되고 있다. 특히 개인 방송에서 제작자 및 사용자에게 편리성을 제공하고 시청자의 실감성 체험을 극대화할 필요가 있다. 이에 따라 본 논문에서는 멀티 제스처가 필요한 실감 미디어를 멀티 디스플레이, 시점 선택, 3차원 객체 복원으로 정의하였다. 또한 사용자 및 제작자의 편리성을 위해 필요한 제스처에 대한 종류를 분석하였으며, 사용자의 다양한 제스처를 인식하고 실감 콘텐츠를 표출하도록 시스템을 구성하였다.

영상 서비스에서 사용자가 시청하는 비디오 화질을 측정하는 것은 사용자의 QoE(Quality of Experience)를 추정할 수 있는 중요한 작업 중 하나이다. 이를 위해 가장 널리 쓰이는 측정 방법 중 PSNR이 있다. PSNR은 원본영상과 시청영상간의 각 픽셀 값의 차이를 계산하여 화질을 측정하는 객관적인 평가 방법이다. 본 논문에서는 객관적 평가 방법인 PSNR에 시청자가 영상 측정 시 느낄 수 있는 시선 인식 집중도를 접목시킨 품질 측정방법을 제안한다. 이는 사용자의 시각적 특성이 고려되기 때문에 보다 사용자에게 맞는 영상 품질을 측정할 수 있게 된다.

The recent progress in multimedia signal processing and transmission technologies has contributed to the extensive use of multimedia devices to watch sports games with small LCD panel. However, the most of video sequences are captured for normal viewing on standard TV or HDTV, for cost reasons, merely resized and delivered without additional editing. This may give the small-display-viewers uncomfortable experiences in understanding what is happening in a scene. For instance, in a soccer video sequence taken by a long-shot camera techniques, the tiny objects (e.g., soccer ball and players) may not be clearly viewed on the small LCD panel. Moreover, it is also difficult to recognize the contents of the scorebox which contains the elapsed time and scores. This renuires intelligent display technique to provide small-display-viewers with better experience. To this end, one of the key technologies is to determine region of interest (ROI) and display the magnified ROI on the screen, where ROI is a part of the scene that viewers pay more attention to than other regions. Examples include a region surrounding a ball in long-shot and a scorebox located in the comer of each frame. In this paper, we propose a scheme for raising viewing experiences of multimedia mobile device users. Instead of taking generic approaches utilizing visually salient features for extraction of ROI in a scene, we take domain-specific approach to exploit unique attributes of the soccer video. The proposed scheme consists of two modules: ROI determination and scorebox extraction. The experimental results show that the proposed scheme offers useful tools for intelligent video display on multimedia mobile devices.

This study intended to investigate the effects of the subtitle location on the decreased working memory abilities caused by aging. A junior group (average age: 26, SD: 3.06, N=27) and a senior group (average age: 61.69, SD=4.18, N=26) participated in this study and they all performed N-back tasks which measured the working memory ability of the participants and video subtitle recognition tasks that assessed the most effectively recognized subtitle locations in the video. The results of the N-back task revealed slower response times and low accuracy rates in the senior group in comparison to the junior group, suggesting lower working memory abilities in the senior group vis-à-vis the junior group. The deterioration of working memory due to aging also negatively influenced the 'left-bottom' subtitle location in the video subtitle recognition task and positively influenced the 'left-center' location of the screen. The deterioration of working memory ability did not affect other subtitle locations. By examining the positive or negative effects of the deterioration of working memory ability as a function of age on subtitle locations, the present study suggests that the selection of suitable subtitle locations taking into account the ages of video viewers would cause information to be more effectively displayed on screen.

This study aims to understand the using characteristics of TV animation and web-based animation of children and investigate the effects of change in viewing process on the purchase of character goods. For this purpose, an online survey was conducted for parents who have children as animation viewers. The results show that there was no difference by age or gender in using both TV and web animation. When parents get animation information on TV, they had their children watch animation through the same TV channel, but the web has no significant relationship between information acquisition path and main service they use. In addition, it is found that parent' perception of TV animation superiority is influenced by respondents' income and children's watching time of animation has no effect on it. Finally, monthly income of households, payment amount of web animation, watching time of TV animation, and perception of quality of TV animation have a significant effect on parents' active purchase of character goods. On the other hand, the purchase intention of the recommended goods is influenced by children's age, the parent's perception about the web animation quality, and the payments of the web animation.

This study has attempted to explore the way to construct the reality and its implication of the narrative elements in TV Audition Reality Show. According to the study results, first of all, two audition reality show has added the special tasks to characters based on the competition and has developed the dramatic events sequentially. And they has suggested the course of way between survival and fail, that is, inclusion and exclusion. As that results, audiences has be immersed in the process of the justification of the star(hero) myth and the dealings of musical elements to see dramatized show of narrative. And they knew audition reality show as non-real fiction, so they enjoyed the pleasure spontaneously. These means that the empowered media reproduced the illusion like star(hero) with the purpose of the commercial and political aim and one of the ideology to acquiesce in the appropriateness of the competition.

A 2 dimensional quality function for quantifying the quality of images observed at viewing regions in contact-type multiview 3 dimensional imaging systems is devised and its effectiveness is verified experimentally. The function allows calculating the locations of viewing regions for patched images of any number of different view images. The images observed at the calculated regions reveal that different parts of the display panel of the system project different view images and match with the function's prediction.

3DTV는 향후 모노스코픽 TV(2DTV)를 대체할 차세대 방송 서비스로 인식되고 있다. 이는 시청자에게 입체감을 제공함으로 인해 기존 모노스코픽 TV에 비해 보다 현장감과 현실감 있는 TV 서비스를 제공할 수 있는 장점이 있다. 전송측면에서 보면 3D 서비스를 위해서는 하나 이상의 시점에서 촬영된 영상이 필요하다. 이를 위해서는 모노스코픽 TV에 비해 전송 용량의 증대를 가져오므로 이를 효율적으로 전송하기 위한 방안이 강구되어야 한다. 본 기고에서는 지상파 방송망과 방송과 통신의 융합 서비스로 불리는 IPTV 망을 연동하여 3D 서비스를 제공하기 위한 전송 방법에 대해 간략하게 소개한다.

In this paper, a smart travel service platform is proposed with PPL(Product Placement) database based on the location of TV viewer who is 's marking by smart devices. This platform is designed with the active PUSH and smart kiosk signage with video clip of LTE/beacon's places. As a result, this PPL-DB platform is inter-worked for the PPL database of category, location, product, favor with interactive tagging in pictures and videos.
