We compare Over-the-Tops (OTTs), Netflix and Amazon Prime Video (APV) with five success factors of innovation. Firstly, Netflix offers better personalized service than APV, because APV has collaborative filtering algorithms to recommend safe bets, not the customers really want. Secondly, APV' user interface is undercooked to lock the members in, even if it has more content and better price offer than Netflix retaining its loyal customers despite the price increase. Thirdly, Netflix has simple subscription model with three tiering, but APV has complicated pricing model having annual and monthly, APV and Prime Video (AV) app, Amazon subscription and extra payment of Amazon Prime Channels (APCs). Fourthly, Amazon has fewer partnership than Netflix especially when it comes to local TV series. Instead, Amazon has live TV channel collaboration including sports content. Lastly, both have strategic and operational agility in their organization well.

It has recently been combined with advanced technologies such as AR and VR, and its application range is expanding to various forms of smart signage. However, until now, digital signage service that reaches us is installed in many floating populations such as bus stops, elevators, and banks and is used in the form of providing news, weather, and advertisements. In addition, large companies, government offices, and outdoor advertising companies occupy the market. The use of such services in small and medium-sized businesses and small retail stores is costly and expensive to manage. Also, it is difficult to generalize the market because services and solutions are being deployed in the market in the form of top-down. Therefore, in this paper, we proposed a digital signage system for transmitting a remote video advertisement that uses a show window in front of the store as a beam project screen for small retail stores, and can remotely set and manage and update it in OSGi service platform.

Nowadays, crowdfunding presents a promising development. This research focuses on the influence of platform strategy and market response on the success of crowdfunding from the perspective of the elaboration likelihood model (ELM) theory. Detailed product specifications, crowdfunding difficulty coefficient, vivid advertising video such as introduction and music, and recommendations from relevant figures are all used to depict platform strategy. Meanwhile, we use the number of lovers, followers, comments and 1 RMB backers to measure the level of market response. And thus, we model the impact of platform strategy and market response on crowdfunding success with empirical studies based on 400 samples of observed value. We found firstly that there exist significant positive relations between the total amount of funds pledged and detailed product specification, vivid advertising video, recommendations from relevant figures and the number of 1 RMB backers. Secondly, the crowdfunding difficulty of projects affects negatively, and significantly, the total amount of funds pledged. Thirdly, the influence of the number of lovers and followers on funds pledged is not significant.

방송에서의 광고의 비중이 높아짐에 따라 광고 수익을 극대화하기 위한 기술의 발전이 활발히 이루어지고 있다. 최근의 이러한 광고 관련 기술들을 일반적으로 Advanced Advertising 이라고 하며 그 중 시청자의 선호에 맞는 광고만을 시청자에게 제공하는 타깃광고(Targeted Advertising) 방식 등 수신기별로 특화된 광고를 제공하는 기술을 클라이언트 기반 광고 삽입 방식이라고 한다. 북미의 인터랙티브 케이블방송 규격인 OCAP(OpenCable Application Platform)은 OCAP DPI(Digital Program Insertion) 라는 명칭의 클라이언트 기반 광고 삽입 방식에 대한 북미 일부 지역에서의 시험 방송의 성공한 후 관련 규격을 OCAP1.1-I01 에 발표하기에 이르렀다. 조만간 상용화되면 OCAP DPI 를 통해 북미 케이블방송 사업자들의 광고 수익 향상에 기여할 것은 물론이고 시청자들의 만족도를 향상시킬 것이다. 이런 움직임은 케이블 진영뿐만 아니라 Open IPTV Forum, ATSC 등 IPTV 나 지상파 TV 진영에서도 이 기술에 대한 타당성 검증 및 표준화가 논의가 활발히 진행되고 있는 실정이다. 본 논문은 클라이언트 기반 광고 삽입 기술에 대해 OCAP DPI 를 구현한 경험을 바탕으로 그 원리 및 동작을 설명하고, DVR(Digital Video Recorder) 또는 PVR(Personal Video Recorder)의 주요 기능인 스토리지에 방송스트림을 저장하고 재생하는 기능을 이용하는 광고 삽입 방법에 대해 제안하며, Cable-IPTV Hybrid 의 웹 접근성을 이용하여 웹 서버에 저장되어 관리 및 운용되는 광고컨텐츠의 스트리밍을 통한 광고 삽입 방법에 대한 제안하고, 마지막으로 실제 이러한 광고 삽입 기술을 적용하는 데에 있어 발생되는 문제점들을 언급하고 그 해결에 대한 의견을 제시한다.

In addition to economic growth and national income increase, China is also experiencing rapid growth in consumption of cosmetics. About 67% of the total trade volume of Chinese cosmetics is made by e-commerce and especially K-Beauty products, which are Korean cosmetics are very popular. According to previous studies, 80% of consumer goods such as cosmetics are affected by the word of mouth information, searching the product information before purchase. Mostly, consumers acquire information related to cosmetics through comments made by other consumers on SNS such as SINA Weibo and Wechat, and recently they also use information about beauty related video channels. Most of the previous online word-of-mouth researches were mainly focused on media itself such as Facebook, Twitter, and blogs. However, the informational characteristics and the expression forms are also diverse. Typical types are text, picture, and video. This study focused on these types. We analyze the unstructured data of SINA Weibo, the SNS representative platform of China, and Meipai, the video platform, and analyze the impact of K-Beauty brand sales by dividing online word-of-mouth information with quantity and direction information. We analyzed about 330,000 data from Meipai, and 110,000 data from SINA Weibo and analyzed the basic properties of cosmetics. As a result of analysis, the amount of online word-of-mouth information has a positive effect on the sales of cosmetics irrespective of the type of media. However, the online videos showed higher impacts than the pictures and texts. Therefore, it is more effective for companies to carry out advertising and promotional activities in parallel with the existing SNS as well as video related information. It is understood that it is important to generate the frequency of exposure irrespective of media type. The positiveness of the video media was significant but the positiveness of the picture and text media was not significant. Due to the nature of information types, the amount of information in video media is more than that in text-oriented media, and video-related channels are emerging all over the world. In particular, China has made a number of video platforms in recent years and has enjoyed popularity among teenagers and thirties. As a result, existing SNS users are being dispersed to video media. We also analyzed the effect of online type of information on the online cosmetics sales by dividing the product type of cosmetics into basic cosmetics and color cosmetics. As a result, basic cosmetics had a positive effect on the sales according to the number of online videos and it was affected by the negative information of the videos. In the case of basic cosmetics, effects or characteristics do not appear immediately like color cosmetics, so information such as changes after use is often transmitted over a period of time. Therefore, it is important for companies to move more quickly to issues generated from video media. Color cosmetics are largely influenced by negative oral statements and sensitive to picture and text-oriented media. Information such as picture and text has the advantage and disadvantage that the process of making it can be made easier than video. Therefore, complaints and opinions are generally expressed in SNS quickly and immediately. Finally, we analyzed how product diversity affects sales according to online word of mouth information type. As a result of the analysis, it can be confirmed that when a variety of products are introduced in a video channel, they have a positive effect on online cosmetics sales. The significance of this study in the theoretical aspect is that, as in the previous studies, online sales have basically proved that K-Beauty cosmetics are also influenced by word-of-mouth. However this study focused on media types and both media have a positive impact on sales, as in previous studies, but it has been proven that video is more informative and influencing than text, depending on media abundance. In addition, according to the existing research on information direction, it is said that the negative influence has more influence, but in the basic study, the correlation is not significant, but the effect of negation in the case of color cosmetics is large. In the case of temporal fashion products such as color cosmetics, fast oral effect is influenced. In practical terms, it is expected that it will be helpful to use advertising strategies on the sales and advertising strategy of K-Beauty cosmetics in China by distinguishing basic and color cosmetics. In addition, it can be said that it recognized the importance of a video advertising strategy such as YouTube and one-person media. The results of this study can be used as basic data for analyzing the big data in understanding the Chinese cosmetics market and establishing appropriate strategies and marketing utilization of related companies.

Colors in design elements are visual non-verbal symbols both sensual and emotional. It is the first priority in the selection of products for the consumers, and also represents differentiated strategies and coherent integration symbols for the brand. Colors in advertising is an important tool to represent the long-term image management for the brand as well as the product image and concept of the advertise. The theme of this paper is to develop creative advertisement analyzing colors from automobile video ads. Analysis results showed that video ads with small cars under 2000cc preferred pastel colors with high saturation and brightness to emphasize on individuality rather than authority. On the other hand video ads with big and luxury cars upper 2000cc preferred dark colors with lower saturation and brightness. Small car video ads focused on product appearance showing the practical value of the car, big luxury car video ads focused on the symbolic image feeling the difference between the representation of the ads. Colors used in advertisement represents the sensitivity of the consumers. In video ads the concept of the color should be set by identifying on who the globule targets are and on what item you show by identifying the corresponding colors sensitivity to suit your advertising strategy will increase the value of the brand and products.
