This experimental research explores the effect of drone's moving image on media audience's flow, arousal of interest and emotional state. Most previous researchers of media image effect insisted that camera movement should be abstained in order to give audience the feeling that movement of figures is in the contents story itself. and camera movement also can disturb natural viewing of audience. For the purpose of finding the effect of drone's moving image on media audience's flow, arousal of interest and emotional state, 2 groups of subjects composed of 56 university students were exposed to 2 different video clips, one with moving drone's image, the other with hovering drone's image. After this experiment, Questions which were designed to measure audience's flow, arousal of interest and emotional state were asked and analysed. This research found that subjects exposed to moving drone's image felt more interested and more positive emotional state than subjects exposed to hovering drone's image. However meaningful effect of drone's moving image on audience's flow was not found.

The development of the digital compression technology and the broadcasting receiver's processing power make it possible to apply a multi-view function to the broadcasting services. The multi-view function is usually utilized to provide simultaneously several programs to viewers or to implement a multi-angle service of a sports program that allows a viewer to choose a video of his/her prefer viewpoint. The paper proposes an integrated method for utilizing a multi-view function in the digital broadcasting environment in which more than 100 programs are on air and there may be various data services which want to use multi-view video clips. For the purpose, a method of composing and transmitting multi-view videos and related information has been devised and a Java API to utilize the rapid editing function of a decoding chip-set has been implemented to clip, resize, and display parts of the multi-view videos.

Considering the growing importance of TV favorite channel setting function due to the rapid increase of number of TV channels, this study tried to find factors which affect the attitude toward and intention to use the favorite channel setting function. As related theories, this study used theory of diffusion of innovation, channel repertoire, channel changing behaviors, and social influences and suggested research hypotheses and questions based on the theories. After collecting data through online survey of 192 general audience, this study empirically analyzed the data by using multiple regression analysis. The result showed that innate innovativeness, relative advantage and social critical mass affected attitude toward using the favorite channel setting function and that compatibility, visibility, social critical mass influenced intention to use the function.

In Korean society, digital contents such as VCC has introduced a new medium of advertisement and has become a culture. This research aims to investigate consumer characteristics for different types of consumption patterns for services dealing with digital contents. A total of 96 statements were extracted from literature review and popular press articles and 39 participants participated in this study. The results show 6 types of consumption patterns: Gak-jang-ee, Second-level Celebrity, Viewers, Politicians, Humanists, and Paris Hilton. These groups demonstrate consumer's behavioral characteristics and personal values. This study is meaningful in that it provides an insight for marketing strategies for corporations dealing with digital contents such as VCC.

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.

In this paper, we design and implement a digital LCD stopwatch function of the remote control. The central controller and LCD stopwatch is implemented based on the clock signal of the crystal oscillator of 8MHz by using ATmega8 processor in the AVR representative series of ATMEL, Communication module basic, ZBS-using the ISM 2.4GHz frequency band at 100. Stopwatch of remote control that has been proposed, it is possible to solve the three problems. First, it is possible to solve the sight deviation between broadcast camera and panelists glance to large LCD stopwatch monitors. Second, it is possible to avoid the trouble of broadcasting cameras cross replacement, Third, it is possible to minimize the inconvenient of the viewer corresponding to the operation of the horizontal movement of the broadcast camera.

The quality of depth images is important in the 3D video system to represent complete 3D contents. However, the original depth image from a depth camera has a low resolution and a flickering problem which shows vibrating depth values in terms of temporal meaning. This problem causes an uncomfortable feeling when we look 3D contents. In order to solve a low resolution problem, we employ 3D warping and a depth weighted joint bilateral filter. A temporal mean filter can be applied to solve the flickering problem while we encounter a residual spectrum problem in the depth image. Thus, after classifying foreground andbackground regions, we use an upsampled depth image for a foreground region and temporal mean image for background region.Test results shows that the proposed method generates a time consistent depth video with a high resolution.

Recently, 3DTV and 3D displays have been released in the market. Accordingly, the production of stereoscopic images has gained much interest. Stereoscopic image being composed of left and right images are currently delivered to viewers without any modifications. The researches on the enhancement of depth perception using high-frequency components and the re-production of natural color by color compensation have been carried out for 2D images. The application of such 2D technologies to 3D stereoscopic images is an aim of this paper. This paper proposes the enhancement of 3D perception by color transformation. For this, we propose a stereo matching method for obtaining a depth map and two color transformation methods such as contrast transformation and background darkening. The effectiveness of the proposed method was verified through experiments.

The outdoor recreation fever that is drastically increasing in Korea could be the result of the interaction between mass media and popular culture as well as increase of leisure time and disposable income. Thus, the purpose of this study is to specify how the exposure of outdoor recreation through mass media influences potential outdoor recreationists. In order to specify this decision-making process, playfulness, which is the intrinsic characteristic of adults' fun and play, was added to the theory of planned behavior, which has high explanation power regarding human behavior. As a result of the study, it turned out that playfulness significantly influences attitude, subjective norm, and perceived behavioral control, and that attitude, subjective norm, and perceived behavioral control also significantly influence behavioral intention. These results specify that playfulness is a factor that has a great effect on outdoor recreation that seeks deviant behavior.

We are exposed to video content and numerous information from digital signage such as convenience stores, coffee shops, restaurants, and elevators on buses and subways 365 days. However, so far, studies have focused solely on the technical effectiveness of digital signage or the consumer experience aspect of digital signage, and little has been done on the impact of teaser advertising on the intent of viewing. Through this study, we hope that the digital signage of convenience stores will develop into a differentiated digital signage area that provides diverse video content experiences to consumers and viewers and allows them to communicate, suggesting a direction as a research that shows that digital content (video) is now recognized as a product in an environment where demand for non-face-to-face and digital content is gradually increasing in 2020 after the global COVID 19.
