In this paper, we propose system design and implementation of FLV Move Picture Solution based on IDC apply to Mini IPTV. IDC of energy minimize and Green Data Center design resources make use of maximization, and Mini IPTV of diverse contents service provider and network provider offer Mini IPTV customers to transmit network. at this time implemented on the improve Move Picture of motion blur and compressibility using FLV solution file format and a compression technique, and reduced traffic cost and solved security question. specially, on the web quickly growing a branch of e-Learning wish to be of help.

최근 전 세계는 지구온난화와 기후변화로 상징되는 '환경'위기와 고유가로 대표되는 '자원'위기를 동시에 맞이하고 있다. 정보화의 가속으로 IT 기기의 증가 및 인터넷의 통신량 증가는 IDC 운영에도 많은 영향을 주고 있다. 그 중에서도 대부분의 운영비용이 막대한 전력 소모로 인해 발생하고 있는 실정이다. 이에 따라 IDC 사업자들은 운영 경비의 비용을 줄이기 위해 IDC의 불필요한 인적, 물적 자원의 소모를 줄이며, 고성능 저비용, 저전력 장비 확보에 많은 관심을 기울이고 있다. 제안 시스템에서는 IDC의 서버와 스토리지 등의 IT 장비와 공조시스템과 전력공급시스템 등의 Non-IT 장비의 자동화 통합 관리를 통하여 인적, 물적 자원을 체계적으로 관리하여 이들의 활용성을 높이고, 나아가 IDC의 운영비용 및 효율을 고도화할 수 있도록 하였다.

본 논문에서는 데이터 센터 내 전력 효율화에 기여할 수 있는 랙 단위 공조방식에 대하여 제안한다. 스마트 폰과 태블릿 등 모바일 디바이스의 확산으로 디지털 콘텐츠와 데이터가 폭발적으로 증가하면서 데이터 센터의 수는 연평균 30%이상 증가하고 있다. 따라서 데이터 센터 내 냉방장비 영역의 효율성을 증가시킬 필요성이 대두되고 있다. 본 연구는 데이터 센터의 냉각비용을 증가시키는 전력 사용량을 줄이고자 진행되었으며 3종류의 냉각 아키텍처 방식 중 랙 단위 아키텍처가 불필요한 냉각 전력 소비를 줄인다는 것을 확인하였다.

As global climate changes, the interest in environmental crisis is increasing and a number of international agreements and regulations against this crisis are being established. Global information technology(IT) corporations are building their own pro-environmental green IT strategies to cope with the regulatory measures. Green IT broadly refers to pro-environmental technologies designed to replace hazardous materials, maximize energy effectivity, and find alternative energies. In the current stage of the IT industry development, Green IT specifically refers to the technologies that deal with the server heat generation and the energy reduction in data center. This study defines the concept of Green IT and reviews its origin and necessity. Then, it examines the issues regarding Green IT industry in Korea as well as other countries and compares the Green IT strategies developed in each country. Reviewing the recent development of IT and data center market enables us to see that overall Green IT strategies focus on the establishment of Green Internet Data Centers. Therefore, this study analyzes the cases in which some domestic and foreign corporations introduced Green Data Centers in order to examine the protocol and legal requirements for building Green IT, the aspects of environmental evaluation and design, and specific strategies for launching Green IT strategies and its future assignments. The conclusions of this study are as follows. First, to introduce Green Data Center as a strategy to build Green IT, the government and corporations should cooperate with each other. Partial introduction at the initial stage is desirable because, through the process, mutual trust between the two parties can be built more smoothly. Second, CEO's determination to build Green IT and continue its operation is indispensable. CEO's are required to have clear understanding as to why Green IT needs to be built and how it should be constructed. Those who initiate the construction of Green Data Center for Green IT need to know the definition and necessity of Green IT while at the same time understanding the implicit meanings of Green IT. They also need to be aware of future-oriented values of Green Data Center and readjust their corporate business activities in the pro-environmental direction. Finally, not only the CEOs' pro-environmental activities but also the change of mind on the part of all corporate employees is required to realize Green IT. It should be remembered that pro-environmental Green IT starts with minor activities.

In this paper, we apply the next generation Internet TV solution, FLV has been designed and implemented. Currently being broadcast in the field to compress HD video in real time, as well as live Internet VOD services are available through the online system, the Internet LIVE broadcast and VOD service easy to operate and UCC services that support the solution. VOD video cameras and in real time using H264 CORECODEC to compress MPEC4, WMV, and real-time video streaming on the Internet, and phone system that supports the first, real-time recording of camera images featured nation's first real-time encoder system (Real time encoder system) is, Web and smart environment suitable for supporting the latest CORECODEC technology and software products. Second, the video can be played in MP4 player and customize your chat, and Custer (customizing) is a possible two-way Internet Broadcasting System. Third, CMS (Contents Management System) feature video content and course management content in real time via the Android phone and iPhone streaming service is available.
