Over the next decade, there are estimated to be 250 billion IoT devices in the future, and a variety of new services and device markets are expected to be created via a new network connection. However, it is difficult to accommodate various sensors and IoT devices, such as product and installation environments, for existing IP/SIP/IMS cameras and video door phone. Additionally, recently, sensors and actuators that can accommodate IoT technology and standards are continually updated. In addition, this paper has developed an SIP/IMS intelligent gateway to flexibly accommodate IoT related equipments and to interface with ZigBee/Z-Wave/NFC endpoints in addition to the gateway basic functions. This intelligent gateway will contribute to the development of the IMS system to replace the VoIP system with the IMS equipment due to the growth of the IMS market.

The market size of online games has been rapidly growing as well as the behaviors of online gaming users have been changed. Online games are different from the traditional video games, because they permit players to interact each other during playing games. Today online gaming is a part of everyday life and social interaction has an impact on online gaming behaviors. Social interaction does not only have a positive impact on online game behaviors, but it also has a negative impact on them such as excessive online game usage. Previous research has a limitation to consider social interaction as a comprehensive concept. In order to fill the gap, we explore the factors of social interaction influencing on excessive online game usage. After reviewing previous literature, this study chooses three factors of social interaction such as escaping loneliness, expanding online social bridging capital, and reinforcing offline social bonding capital. The findings show that all of three factors of social interaction positively affect the excessive online game usage.

Recently, the games on the market are getting rich and excellent in the category of design and productions. The style and production quality of cut-scenes also have achieved a continuous development, so how to stand out from multiple designs and gain popularity always acts as a challenge to designers. However, such design strategy up to developers will be failed to judge whether or not design achievements are loved by players and thus cannot meet rapidly changing market demands on both in a quantity and quality. Therefore, this study holds that cut-scene design for video games must set out from user-centered design(UCD). According to literatures with respect to product market, we know that Market Pull imposes far more impacts on success in bringing new products to the market than the technology Push, hence players actually determines the success of a game in competitive game market. This study will help to enhance the immersion of playing game, including the interest and standing out the designer's message without distorting the original impression in the game publishing environment.

IMS(IP Multi-Media Subsystem) base on the IP service platform which can offer multimedia as the voice, audio, video, and data is service platform. In 3G mobile communication in the early day, IMS had a suggestion for supporting to multimedia service in the 3GPP. But now It is broadly substituting in the IPTV, wire phone company and it is substituted in internet platform base on the soft-switch in currently. Especially nowadays, 4G LTE in a mobile communication company is rapidly growing in market. Therefore, in this study, we had designed to the main prosser that can admit to 1,000 user over and SIP gateway which can link the IMS 코어 that can link SIP Device which adopt the standard protocol on the SIP.

This study analyzes the characteristics of popular channels of YouTube created in South Korea. As the science and technology have developed, the ordinary people come to upload their own videos after filming them. Regarding YouTube, the most popular video provide service in the world, this study researches the traits of popular YouTube channels produced in South Korea. Specifically, top 100 channels of 1) Most Subscribed 2) Most Viewed are researched, then it explores further by classifying them as 1) The number of the most subscribed/the most viewed 2) The number of videos 3) The number of viewed/subscribed 4) Genre 5) Type of creator. Thus, it not only reveals the multi-dimensional aspects of popular YouTube channels in South Korea but also prospects the market of Multi-Channel Network(MCN).

It is essential to support the image and video analysis technology such as motion detection since the DVR and NVR storage were adopted in the real time visual surveillance system. Especially the network camera would be popular as a video input device. The traditional CCTV that supports analog video data get be replaced by the network camera. In this paper, we present the design and implementation of video surveillance system that provides the real time motion detection by the video storage server. The mobile application also has been implemented in order to provides the retrieval functionality of image analysis results. We develop the video analysis server with open source library OpenCV and implement the daemon process for video input processing and real-time image analysis in our video surveillance system.

방송장비가 네트워크 기술을 만나 진화하고 있다. 네트워크 케이블로 초고해상도 영상과 다채널 음향 데이터를 송·수신하고, 다수의 방송장비 제어를 가능케 하는 NDI(Network Device Interface)의 등장으로 방송장비와 네트워크 기술이 융합되고 있다. 최근 국내외 여러 기업이 네트워크 기반의 방송 솔루션을 출시하고 있어, 관련 산업계는 향후 방송장비 시장이 네트워크 기반으로 개편될 것으로 전망하고 있다. NDI는 뉴텍(NewTek)에서 개발한 IP 전송 프로토콜의 일종으로 무(無)손실, 압축, 제로(Zero) 딜레이, 멀티캐스트 등의 특징을 갖고 있다. 기존 비디오 전송 프로토콜이었던 SDI(Serial Device Interface)와는 다르게 네트워크에서 방송장비를 운용할 수 있도록 만들어진 프로토콜이다. 본 논문에서는 NDI를 기반으로 앞으로 다가올 포스트 코로나 시대에 대응할 효율적인 방송 환경을 제안하고자 한다.

The purpose of this paper is to provide an answer for the following question: What are the major shifts and implications of the unprecedently competitive and rapidly changing media ecosystem in the era of N-screen and OTT services? I've attempted to understand the complex and competitive nexus among media from an historical context by focusing on the displacement vs. complement thesis. The TPC model by Han has been employed for the analysis of the current dynamics of US media industries by triangulating three areas: Technology/industry, public policy and consumer/culture. More specifically, the US media landscape is initially divided into two competitive turfs - the competitors equipped with OTT services and the legacy media industry, and then the traditional media industry was grouped again into PayTV group(telecom service providers with IPTV and mobile TV, cable/Satellite TV networks) and Free (over-the-air) TV networks. Six major shifts were identified by the analysis: power shift in telecom carriers, power shifts in TV industry, Telecom/OTT partnership, time shifts, place shifts, and finally business model shifts.

The objective of this article is to identify an alternative strategy for brand marketing through a case study of the Korean boy band BTS, which has recently seen a huge success in the global music scene. BTS has actively used transmedia storytelling as a tool to survive in the competitive music market. Transmedia storytelling refers to stories that are expanded across different media platforms, engaging audiences to explore from one medium to another to undergo multiple experiences. It gives audiences various ways of enjoying cultural content and participating in cultural content production through numerous media outlets. BTS has established and spread its fictional universe through albums, music videos, short films and webtoons, and has launched diverse projects where fans actively share, create, and play with their content. By inviting fans to actively participate in and interact with the BTS universe spreading through multiple media platforms, BTS can keep its fans engaged and energized. These activities have generated an emotional bond between BTS and their fans, which further leads to a worldwide fandom, based not on a producer-customer relationship but on mutual trust. The BTS case demonstrates the potential of transmedia storytelling as a useful benchmark to provide a positive brand experience for customers, which eventually enhances brand attachment and brand loyalty.
