2005년 12월 1일 DMB(Digital Multimedia Broadcasting) 본 방송이 실시된 이후 다양한 형태의 방송, 통신 융합 서비스가 시도되었다. 그러나 DMB가 성공적으로 시장에 정착하였음에도 불구하고 방송사 등 시장 참여자들의 수익 창출의 어려움, 속도 및 요금 측면에서의 양방향 망의 한계, 방송사, 통신사의 시스템 및 망에 종속적이며 폐쇄적인 콘텐츠 제작 및 제공 방식 등으로 인하여 성공을 거두지 못하였다. 그러나 스마트 폰과 같은 모바일 스마트 디바이스의 성공으로 방송, 통신 서비스 시장에 새로운 전기가 마련되어 다양한 융합 서비스가 시도될 것으로 예상되며, 지상파 DMB가 이러한 다양한 서비스와의 경쟁에서 우위를 점하고 중심 매체로 자리잡기 위해서는 새로운 개념의 융합 서비스 플랫폼이 필요하다. 이에 본 논문에서는 이러한 새로운 개념의 플랫폼인 'HTML5 기반 융합 모바일방송 플랫폼'을 제안하고 실제 구현 예를 통하여 그 가능성을 제시하고자 한다. 제안하는 플랫폼은 누구나 콘텐츠 제공에 참여할 수 있고, 다양한 망, 단말, 서비스 모델이 융합되며, 표준화되고 개방된 API(Application Programming Interface)를 통하여 이를 소비할 수 있도록 하는 개념으로, 방송 콘텐츠 및 이에 의해 파생된 다양한 리치 미디어 콘텐츠의 생성, 전달, 소비에 이르는 생태계 전반에 대한 것이다. 이러한 플랫폼의 가능성을 제시하기 위하여 KBS(Korean Broadcasting System)는 서비스 시스템, 수신 프로그램 개발, 시험 서비스 구현 등의 개발을 진행하고 있으며, 그 결과를 본 논문에서 소개하고자 한다.

Virtual reality items are increased take-all type of markets like Universal, such as the United States as a leader in the virtual reality technology. Multi-user have to get direct experiences with the whole body like visual, tactile, hearing, sense of movement, and it must be developed new forms of content platform to enjoy immerse deeply into the content. Visitors are not to enjoy the content passively but rather to enjoy the content actively. So it like that should develope content to maximize the immersion. It need the development of new forms of mixed 5D virtual reality Attraction content with all of factors like $360^{\circ}$ circle vision, stereoscopic images, interaction, simulator, and the environmental effect. We proposes how to make the color and brightness calibration technology for this purpose.

In this paper, we present a service model which serves multimedia contents to end consumer(End-user) that have various mobile communication terminals under a communication & broadcasting converged environment that broadcasting and communication networks are linked. A main feature of this service model is that it has a distribution structure that deliver to end consumer via adaptation of content from production of contents offering End to End (E2E) media QoS and personalized contents consumption. The proposed service model may be used as a reference model for distribution of multimedia content in communication & broadcasting converged environment in the future.

With the steady growth of the content industry, the need for research that automatically recommending content suitable for individual tastes is increasing. In order to improve the accuracy of automatic content recommendation, it is needed to fuse existing recommendation techniques using users' preference history for contents along with recommendation techniques using content metadata or features extracted from the content itself. In this work, we propose a new graph-based music recommendation method which learns an LSTM-based classification model to automatically extract appropriate tagging words from sound data and apply the extracted tagging words together with the users' preferred music lists and music metadata to graph-based music recommendation. Experimental results show that the proposed method outperforms existing recommendation methods in terms of the recommendation accuracy.

Humanities knowledge makes the learners overcome the boundaries of study and can be applied variously by means of contents for study. This paper suggests application contents plans designed as the learning tools for blended learning, which can be sure of the possibility to the extension of other fields. Literary education with application contents has effects followings: First, smart device based on the web under the ubiquitous circumstances has the information system like the neuron's. So the application selects the necessary information and makes the contents for infusion into the education. Also it provides with more abundant and extended information system. With this approach, learners are able to get further literary knowledge and promote the ability for tapping them for new knowledge as well. Lastly, literature applied to the class with web contents is based on the foundation that creates new knowledge necessary for culture, arts, and so on. As a result, the education using web contents achieves the boundless of study, which is the final goal of the blended learning.

Modern society is the era of convergence, and storytelling requires the necessity of storytelling in which two types of data types, emotional stories and information, are fused. Particularly, in the case of VR contents, the user must directly participate in the content and select the information through the process of freely searching $360^{\circ}$ space, so that the user can interact with the content immediately. Therefore, there is a limit to access to the existing storytelling method, and it is considered that the implementation of 'convergent storytelling' that meets two areas of sensitivity and information is considered to be an urgent genre. In this paper, we focus on the spatial characteristics of VR contents, and then, as a way to effectively implement 'convergent storytelling' in VR contents, We propose a custom system by organizing the type into a circle structure. Based on this, it is expected that the technology will be developed into a research of a personalized system that meets two areas of emotion and information by utilizing the context recognition process for VR content and interaction in the fourth industrial revolution era.

In this study, a recommendation algorithm was implemented by learning a deep learning-based classification model for consumer data. For this purpose, a meaningful result is presented as a result of learning using ResNet50, which is commonly used in classification tasks by converting user data into images.

One of the most typical examples of convergence is IPTV, a convergence of broadcast and telecommunication. Demand for IPTV has been increased so rapidly that a new TV set, called a smart TV, has appeared. One of the most important factors for IPTV business success is content. If an IPTV station provides popular content and subscribers can conveniently watch it then the station has a good chance of success. Therefore, the content management module is extremely important component of IPTV systems. In the current IPTV systems, operators must be present at the office to access a Content Management System(CMS). We implement a web CMS so that the operators can access the CMS anytime and anywhere as long as they are connected to Internet.

The learners using learning content through the smart devices can access to the Internet from anytime and anywhere. However, with the rapid increase of learning content on the Web, it will be time-consuming for learners to find contents they really want to and need to study. Therefore, e-learning systems should not only provide flexible content delivery, but support adaptive harmonizing fusion content. The harmonizing fusion content it is a very important in fusion e-learning service. The representative method to provide synchronization between fusion content is a provide absolute time value between of the contents. However, this method is occurs a problem transferring time delay. Also, to enter an absolute time value for the duration of the each content is several problems arise. In this paper introduces a new smart e-smart service support the harmonizing media based technology to create synchronized learning presentation.
