Various streaming technologies are being studied to guarantee the QoE of viewers due to the development of realistic media. HTTP adaptive streaming is a typical example, and it is based on HTTP / 1.1 and TCP. These protocols have become one of the causes of delaying the image delay and increasing the waiting time of web pages. Therefore, in this paper, we propose a QUIC-DASH system applying the UDP-based transmission protocols QUIC and HTTP / 2 to the MPEG-DASH system after analyzing various transmission protocols and development process of HTTP. Through experiments, the QUIC-DASH system confirmed the possibility of providing optimal performance in terms of transmission speed of LTE environment than existing system. We also suggest various future studies for better performance.

With the advent of smart media, short and fast-paced video content appeared, and conditions for viewing changed to viewing in environments where the perception is dispersed due to distracting and complicated external situations in a short period of time. Accordingly, smart media videos are quickly delivering meaning while keeping the eyes of viewers who lack patience. Our eyes and brain have a hard time accepting image information that flows through the constraints of a small screen. Our visual perception is limited in terms of acceptable visual information and, in particular, less cognition in moving images, so the production of smart media images should be directed in a way that enhances perceptual understanding. To be able to effectively communicate what you want to talk about while reducing the visual burden, intuitive image comprehension is needed by applying intuitiveness and behavioral induction to the moving images. Close-up shot, stable structure such as frontality and three-division structure, and color have such 'visual affordance' Therefore we need to use that device appropriately.

This study attempts to investigate the influence of the parental reality show viewing on both the marriage expectation and family value. More specifically, this study investigate the effect of the parental reality show() viewing on marriage expectation(romance and partner expectation), fair parental role model value, and parental nursing efficacy. Indeed, the mediation effects of wishful identification were examined. For this purpose, this study surveyed 407 college students from three different areas. The results showed that the viewing had significant influence on both romance and partner expectation directly as well as indirectly through wishful identification. For the family value, the viewing did not directly influenced on the fair parental role model value, however, it had indirect effects through wishful identification. Meanwhile, viewing had only the direct effect on the parental nursing efficacy.

The $360^{\circ}$ video has a lot of image information and usefulness; however, the position of the audio source judged by hearing is different from the position on the screen. Therefore, human feels tired, the immersion decrease and user cant watch the video for Moreer time. In this paper, the concordance rate of the video and the audio localization is defined. The rate is expressed in a percentage. It means how much the system makes the sound localization real according to the position of the source on the screen. With this rate, the audio localization performance of immersive audio producing and playing system can be evaluated. It will be helpful for developers to make the higher performance system and expected to contribute to make makinguality system with reality.

This study aims to figure out perceived substitutability between video clips distributed on Naver TV cast and regular TV program. An online survey was conducted for a week on October 2017, and we collected several responses, such as viewing time, viewing motive, the extent of viewing for video clip categories, and perceived substitutability between video clips and regular TV program. The dependent variable is Naver TV cast users' perceived substitutability between video clips and regular TV program, and the independent variables are viewing time, viewing motive and viewing degree by video clip categories. With these variables, hierarchical regression was conducted. The result shows that viewing time, use motives, including personal relations, booming issue and selective use, and the extent of web-based video content viewing positively affect on Naver TV cast users' perceived substitutability.

This study constructed a cognitive model of information processing to understand the topic of a sound material and its characteristics. It then proposed methods to generate sound summaries, by incorporating anterior-posterior N400/P600 components of event-related potential (ERP) response, into the language representation of the cognitive model of information processing. For this end, research hypotheses were established and verified them through ERP experiments, finding that P600 is crucial in screening topic-relevant shots from topic-irrelevant shots. The results of this study can be applied to the design of classification algorithm, which can then be used to generate the content-based metadata, such as generic or personalized sound summaries and video skims.
