The development of SNS and video platforms provided an opportunity to explode the activation of content production and consumption. However, in the legacy system, due to the host-based location-oriented data transmission, there are inherent limitations in efficient operation and management. As an alternative to this, a Contents Centric Network (CCN) was studied. In this paper, when intermediate nodes located between the information provider and the information requester between the real-time streaming services in the CCN environment move or restrict their use, failure through monitoring of wireless reception strength to solve problems like disconnection of transmission quality at the information consumer. We propose a stable intermediate node management mechanism through active response before occurrence.

Recently, studies for effective multimedia contents delivery have been widely performed in the multimedia streaming area. Overlay multicast, which can be implemented in the application layer, is method to transmit multimedia content's effectively. The Overlay multicast method can implement multicast transmission without changing the physical layer, and it has the characteristic that the application method can be diversify according to the algorithm. This paper has proposed the backup path construction method of overlay multicast for stabilized multimedia contents transmission. The proposed method can construct a backup path with the minimum searching method for guaranteed QoS(Quality of Service) and in overlay multicast so a fast and simple backup path can be constructed.

Today, social media has become a vital tool. The world communicates and reaches the news and each other's opinions through social media accounts. Recently, considerable research has been done on analyzing social media due to its rich data content. At the same time, since the beginning of the COVID-19 pandemic, which has afflicted so many around the world, the search for a vaccine has been intense. There have been many studies analyzing people's feelings during a crisis. This study aims to understand people's opinions about available Coronavirus vaccines through a learning model that was developed for this purpose. The dataset was collected using Twitter's streaming Application Programming Interface (API) , then combined with another dataset that had already been collected. The final dataset was cleaned, then analyzed using Python. Polarity and subjectivity functions were used to obtain the results. The results showed that most people had positive opinions toward vaccines in general and toward the Pfizer one.

The online performance market is increasing due to recent pandemic events. However, due to the short introduction time of domestic online performances, there is a lack of related prior studies or success stories. In addition, most of these projects are short-lived projects or poor profits, so it is necessary to study how to activate them. The Sac on Screen project, which has been in progress since 10 years ago, has its own imaging experience, and the screening works and screening venues are also diverse, so it is an object of study. In addition, since annual satisfaction surveys are conducted, the business was evaluated based on the voice of customers from the data of the past three years. Based on the analyzed results, a free and paid version of the business model canvas was drawn through a group of experts. As a result of this synthesis, the following major implications were drawn. First, expanding research on online performances, second, needing a sense of responsibility for quality management of content, third, increasing diversity in content selection, and fourth, enhancing the liveliness of online performances, Fifth, efforts are needed to attract private investment and develop value-added products.

With high speed communication network and supplement of high quality multimedia devices, large demand of multimedia service stimulates digital signing industry to step forward to new opportunities. But in order to provide competitive quality services, Integrated management system is required. Digital signs use technologies such as LCD, LED and Projection to display content such as digital images, video, streaming media, and information. Digital signs rely on a variety of hardware to deliver the contents. The components of a typical digital sign installation include one or more display screens, one or more media players, and a content management server for each player. To improve the existing high cost and less efficient management system, this paper suggest cost effective Integrated Digital Signage Management System with the results of analysis of existing system. Also this paper presents an actual implementation on entertainment company to evaluate the suitability, to prove the result of superior performance of proposed system.

This study aims to contribute to the understanding of consumer behavior during the COVID-19 by comparing blog reviews of an over-the-top (OTT) online video service from before and during the pandemic. We anticipate that the COVID-19 outbreak prompts the use of the OTT service as part of an emotion-focused coping strategy derived from the loss of personal control and the subsequent avoidance motivation. We also posit that a strong yearning for life before COVID-19 will increase interest in the content that fulfills a need for nostalgia. Our analysis of Netflix reviews provides empirical evidence of the effects of an emotion-focused coping strategy and nostalgia on OTT service usage. First, the titles of the reviews posted during COVID-19 indicate that consumers were less likely to mention OTT services other than Netflix, more interested in domestic content, and used OTT services as an avoidance-denial strategy. Second, the blog content demonstrates that while pre-COVID reviews tend to focus on the practical benefits of OTT services, those posted during the pandemic focus on mood, emotions, and dialogue. In addition, interest in comedy and romance genres increased during COVID-19. Third, we identified a greater preference for realistic or everyday content that depicted the pre-pandemic era. This is the first empirical study to investigate the effects of COVID-19 on video streaming usage in Korea. In addition, this research contributes to the field of marketing by expanding our understanding of online video service users during COVID-19 and identifies practical implications for OTT services in the midst of a pandemic.
