인터넷의 거센 물결에 국내 PC통신 환경이 변화하고 있다. 텍스트 위주의 정보 제공에서 멀티미디어 요소를 겸비한 콘텐트 중심으로 형태가 바뀌고 있는 것이다. 이런 변화의 물결 속에 정보제공업자의 명칭도 IP(Information Provider)에서 CP(Content Provider)로 바뀌고 있으며, 넷츠고와 채널아이 등 CP를 중심으로 한 통신사들이 기존 통신사를 위협하고 있다.

With the opening of digital broadcast services and development of wire/wireless Internet, the current multimedia broadcasting is provided for has various services. The user will be provided lots of various content through the various channel and media. Content provider and consumer want the various service using content with the better quality which is fit to user preference. For transmitting this content in the limited transmission channel capacity, it needs to transmit the highly compressed content which user wants. The content of 3D mesh model-based on MPEG-4 enables the various content service that provides the lower capacity and the better quality, and Targeting service enables just provide the contents that user more wants and likes. The adaption of Java application program and 3D program can provide the content service utilizing 3D mesh model, so content provider and consumer can share the more information about the content. This paper has presented the study on the targeting service using compression of 3D mesh model-based on MPEG-4 and the adaptation of Java application program using it

M-commerce services are rapidly emerging with recent advances in mobile devices and wireless communications. Internet Shopping mall managers provide mobile phone users with their mobile shopping malls for m-commerce. However, these mobile shopping malls usually have their own sites which are not compatible with their Internet shopping malls, thus resulting in inefficiency to manage the two kinds of shopping malls. In this paper, we develop a M-commerce content provider system to effectively bring Internet shopping malls to mobile phones by extracting items only concerned to users from product documents. We then apply and evaluate the system over a specific internet shopping mall site. The results show that the system reduces considerably the amount of data transferred to user's mobile phones compared with using general web browsers.

Various types of media services are emerging due to the development of Internet and digital media production and distribution technologies. Various DRM technologies are being developed to prevent illegal copying of media contents and to protect the rights of content creators. There is a problem that the DRM provider and the content service provider must provide services in a mutually dependent manner through individual contracts. In this paper, we propose a cloud-based DRM market system which can be used only by content service providers when necessary for various DRM. The DRM market system is expected to show the effect of service activation for related small and medium sized companies by providing an interface that satisfies the requirements of DRM providers and contents service providers by using multi DRM technology.

In this paper, we propose 'a self - conformance system of convergence security provider' to provide basic data for security and reliability of convergence industrial technology, system and service. It is difficult to evaluate convergence security systems, limited to information and communication service providers, unable to check convergence security items, burden of submission documents, difficulty in measuring convergence security service level and we will summarize product and service-based requirements that can be integrated and systematically measure the level of convergence security and define renewed life cycle-based convergence security information and content security and assurance requirements. On the basis of this, each convergence security company declares conformity with the standard itself without the certification of the certification body, and introduces the provider conformity certification system which can manufacture and sell. This will enable the company to strengthen its competitiveness through timely launch and implementation of products and services and cost reduction.

In the distance education system existing, change of content by the content provider has not been performed in real time. But current car model is changed quickly. So it must modifying by contents provider in real-time. In this paper, we implement contents authoring system for modifying E-training contents easily. Especially, it use HTML5 technology. Through it, contents providers can modifying contents in various platforms easily.

스마트폰의 대중화와 보편화가 이루어지면서 스마트폰 개발 환경도 많은 발전을 이루었다. 스마트폰 운영체제들은 각각 고유의 특성을 가지고 다양한 기능들을 제공한다. 안드로이드에서는 서로 다른 어플리케이션끼리 데이터를 공유하기 위해 ContentProvider를 사용한다. 그러나 공격자가 역공학 기술을 이용할 경우 다른 어플리케이션이 데이터베이스에 접근하여 불법적 정보유출을 할 수 있다는 취약점을 가지고 있다. 본 논문에서는 ContentProvider를 통한 정보유출의 취약점을 분석하였다.

Content Delivery Network(CDN) is a mechanism to deliver multimedia content to end users on behalf of web content providers. Provider's content is distributed from content server to a set of delivery platforms located at Internet Service Providers(ISPs) through the CDN in order to realize better performance and availability than the system of centralized provider's servers. Existing work on CDN has primarily focused on techniques for efficiently multicasting the content from content server to the delivery platforms or to end users. Multimedia contents usually require broader bandwidth and accordingly WDM broadcast network has been highly recommended for the infrastructure network of CDN. In this paper, we propose methods for partitioning a multicast group into smaller subgroups using the previous status of receivers. Through the computer simulation, we show that proposed algorithm are useful to reduce the average receiver's waiting time and the number of transmissions.

This study investigates the decisive factors affecting the survival or collapse of cable networks in the Korean paid broadcasting market from 1993 to 2010. The effects of performance variables discussed in previous studies were verified through survival analyses. According to the results, the most influential factors in the survival of cable networks were horizontal integration (MPP), channel genre, the scheduling of HDTV content, and the proportion of access program scheduling. These findings imply that the differentiation strategy of content suppliers is the most decisive factor among all business performance-related factors. Specifically, the content supply power and strategy of the program provider (PP) have the greatest influence on cable network viability. The present study is meaningful as the first attempt to establish the performance of PPs in Korean pay broadcasting markets through the viewpoint of organizational mortality. Accordingly, the present study can supplement the results of cross-sectional studies conducted with smaller samples.

This study addressed status of PP(Program Provider) market, particularly focusing on independent PP. This research selected 14 independent channels and did in depth interviews for them. This study analyzed 14 channels in terms of management, production, and contents. The result showed that independent channels were in inferior condition than MPP(multiple PP) on all the aspects of management, production and content. The management structure of the PP were very vulnerable, production environment was not good. The PP were placed in a difficult environment in terms of production and purchases of content, therefore focused on distribution rather than production. This unbalance on the PP market resulted in negative effect on Korea's contents industry as well as PP industry. Therefore, this study suggested policy and regulatory reforms are needed to improve inferior status of independent PP.
