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.

비디오 클립은 최근 온라인 상에서 흔히 볼 수 있는 짧은 동영상으로 이러한 동영상 클립의 대규모 유입으로 유사한 비디오 클립을 검색하는 동영상 검색 엔진의 필요성이 크게 증가하였다. BCS은 최초의 단일 비디오 클립 표현 모델로 비디오 클립을 주성분 분석을 통해 얻어진 좌표축들을 그 위로 사상된 데이터들로 제한한 것들로 이루어진 좌표계로 요약한다. 그러나 BCS 은 영상의 순서를 무시한 벡터로 표현되므로 세밀한 유사도 구별이 불가능하다. 본 논문에서는 유사한 동영상에 대한 사람의 판단은 서로 유사한 일부분이 많이 존재하는 것을 기반으로 하는 점에 착안하여 하나의 동영상 클립을 샷 단위로 나누어 여러 개의 BCS 으로 나타낸 다음, 이들간의 유사도 측정을 통해 검색의 성능을 높이고자 하였다. 실험 결과 만족할 만한 정확도로 유사한 동영상 클립을 검색해 내는 것을 확인할 수 있다.

This study analyzed Naver TV users' pattern of video clip watching, and analyzed the factors affecting the popularity of Naver TV's video clip. We selected 572 individual video clips that were ranked 50th in Naver TV rankings from September 10th to September 24th in 2017. We classified video clip's characteristics into several factors, including the number of likes, the number of subscriber, genre, video clip's types, and star appearances. We indexed the popularity of video clip, which implies the degree of popularity for each video clip. The results showed that the number of likes for video clips and the number of subscribers for each video clip were positively related to the popularity of video clip. Video clip's genre, video clip's type and star power positively affected the popularity of video clip. The effect of extras genre on the popularity of video clip was the lowest, followed by entertainment, music, and drama genre. but the difference among entertainment, music and drama genre was not statistically significant. Web-only video and non-broadcast video positively affected the popularity of video clip. Finally, the popularity of video clip was higher when stars appeared in the video clip.

The purpose of this study is to search shot clip' using variables influencing on the VOD purchase intention and watching intention of real-time broadcasting. This research focused on usage motivation, usage experience such as use time, time of utilization, genre, utilization pattern. Controlling demographic factors, results show that personal relation, benefit against whole broadcast, education genre, watching video, video sharing and recommendation were statistically influential to VOD purchase intention. And, results show that flexibility of use, drama/movie genre, read and write comments were statistically influential to watching intention of real-time broadcasting.

Sports video is a very critical information resource. High-precision extraction of effective segments in sports video can better assist coaches in analyzing the player's actions in the video, and enable users to more intuitively appreciate the player's hitting action. Aiming at the shortcomings of the current sports video clip extraction results, such as strong subjectivity, large workload and low efficiency, a classification method of sports video clips based on MobileNetV3 is proposed to save user time. Experiments evaluate the effectiveness of effective segment extraction. Among the extracted segments, the effective proportion is 97.0%, indicating that the effective segment extraction results are good, and it can lay the foundation for the construction of the subsequent badminton action metadata video dataset.

Video indexing plays an important role in the applications such as digital video libraries or web VOD which archive large volume of digital videos. Video indexing is usually based on video segmentation. In this paper, we propose a software tool called V2Web Studio which can generate video clips utilizing shot boundary detection algorithm. With the V2Web Studio, the process of clip generation consists of the following four steps: 1) Automatic detection of shot boundaries by parsing the video, 2) Elimination of errors by manually verifying the results of the detection, 3) Building a modeling structure of logical hierarchy using the verified shots, and 4) Generating multiple video clips corresponding to each logically modeled segment. The aforementioned steps are performed by shot detector, shot verifier, video modeler and clip generator in the V2Web Studio respectively.

This study examines the effect of performers on the number of views and likes of entertainment show clips consumed on AVOD short form platform. Multiple regression analysis was performed, setting program viewing factors and performer's topicality index as independent variables, and setting the number of views and likes of clips as dependent variables. As a result of the analysis, performer's topicality index had a positive(+) effect on both dependent variables. According to standardized coefficient, on the number of views, the standardization coefficient of the performer's topicality index was the second highest, and on the number of likes it was the highest among variables. The results suggest that performers contribute a lot to the success of clips on AVOD short form platform.

This paper presented a method of extracting shape information from a clipart image and then measured the similarity between clipart images using the extracted shape information. The results indicated that the outlines of the extracted clipart images were clearer that those of the original images. Previous methods of extracting shape information could be classified into outline-based methods and region-based methods. Included in the former category, the proposed method expressed the convex and concave aspects of an outline using the ratio of a rectangle. Accordingly, the proposed method was superior in expressing shape information than previous outline-based feature methods.
