Smart-phone, PC or tablet platforms, such as smart terminals spread to the masses trying to capitalize. Smart TV also is increasing. In Korea, market size of TV is growing fast with growth of risk of hacking. In this paper, several kinds of Smart TV hacking cases are presented with the possibility of attacks against the vulnerability analysis and countermeasures. Most of the Linux operating system is open. Thus, it is vulnerable for latest hacking techniques. Most are based on the Linux OS to enhance security mount Sand-Box. However, bypass procedure using the technique, or APT attacks can avoid San-Box technique. New hacking techniques and a variety of ways will occur in the future. Therefore, this paper will develop Smart TV, and it analysis of a security threat and establishes better prepared in the future because new hacking attacks are expected to prepare more.

In this paper, we propose a novel motion recognition platform using smart-phone tracking and color communication. The interface requires only a camera and a personal smart-phone to provide a motion control interface rather than expensive equipment. The platform recognizes the user's gestures by the tracking 3D distance and the rotation angle of the smart-phone, which acts essentially as a motion controller in the user's hand. Also, a color coded communication method using RGB color combinations is included within the interface. Users can conveniently send or receive any text data through this function, and the data can be transferred continuously even while the user is performing gestures. We present the result that implementation of viable contents based on the proposed motion recognition platform.

최근 스마트폰이 급격하게 보급되면서 1인 1스마트폰 시대가 열렸다. 이에 스마트 TV를 이용할 때 스마트폰을 활용하여 기능을 더욱 향상시키는 기술이 주목받고 있다. 해당 프로젝트에서는 스마트 TV의 영상을 시청하고자 할 때 홈시어터 등의 장비 대신 스마트폰을 활용하고자한다. TV의 기본 2채널 스피커가 아닌 5.1 채널을 구축하고 다채널 서라운드를 지원하여 더욱 풍부한 음향이 제공되는 환경에서 스마트 TV의 영상을 관람 가능한 시스템을 구현하였다. 스마트 TV 1대와 스마트폰 3대를 이용하여 구축하였고, AllShare Framework를 통하여 디바이스 간 연결을 하고, FFmpeg과 Chord SDK로 사운드 채널 분리 및 디바이스 사운드 동기화 처리를 통하여 출력 딜레이를 최소화한다.

It's been several years since IPTV(Internet Protocol Television), which is typical conversed broadcasting communication service come up to a new growth power. Although our broadcasting communication infrastructure has global competitiveness, it's been late to be commercialized rather than other countries due to lack of timely supporting policies. Also rising of smart circumstances beginning with smart phone makes smart TV grow faster, so expansibility of IPTV become shrink. This study suggests IPTV the way to get over this circumstances and the effort of government or industries.

These days as smart TVs or android set top boxes have come into wide use, VoIP(Voice over Internet Protocol) services such as the Skype which can beused on computer system, can be also accessed by smart TVs or set top boxes. and the various kinds of distance learning programs have been developed on smart TVs or set top boxes. but when users have utilized a webcam with smart TVs or set top boxes, users have to go in front of smart TVs or set top boxes In this research paper, the new technology can be solved the problem of webcam use according to chaned environment. This tech is related with the wireless webcam one which can be applicable to open spaces such as living room with some distance between user and smart TV. There are few problems in long distance the test results show high reliability in living room with some distance.

Recently people have increased to climb mountain. Owing to developing IT technology, the number of people using smart phone have increased remarkably as well. In this context, the Korea Forest Service has implemented the project of Mountain Climbing Information Public Service(MCIPS). The purpose of the MCIPS is to support climbing safely based on a trail map of spatial data of GIS(geographic information system). The customer will be able to access the MCIPS through n-screen(IP-TV, Web Site, Smart phone, Galaxy tab) provided a broadcasting and telecommunication convergence service. In addition, the MCIPS would support two-way communication through connecting to Twitter and Youtube. The MCIPS will make the customer fun using Augmented Reality(AR) of Smart phone(Android) and contribute to protecting people from mountain accidents.

The game Industry has been a major leader in business world with its size and volume in terms of profit and culture contents, and ever increasing at the moment. Cloud Game has appeared as a new, combined game format, playable on smart TV and smart phone with its upgraded storage size and fast spreading N-screen. This research studies the present reality of the cloud industry by focusing on three categories which are device type, Platform, and game contents consequently in order to determine the future prospect of cloud games. First, the cloud game business will thrive as devices such as smart TV and smart phone are used widely. Second, the cloud game industry will have a new era when OS systems of Platform are united effectively. Third, the previous platform holders will have to face new challenges brought up by cloud games' service providers. Forth, the gamer, developer, and service provider need each other in order to widen the spectrum of business in cloud game industry.

Recently, request of IPTV was increase. It is a multi-screen service by used TV, PC, and smart-phones. Especially, IPTV and smart-phone linked multi-screen service are very growth by user's recommends. Now, IPTV have a security service partial and multi-screen service. But smart-phone and multi-screen service don't have security service. And authentication service for smart-phone and IPTV linked multi-screen service is don't.. Therefore, We propose that user authentication system for multi-screen service with IPTV and multi-device linked authentcation services. Our proposed system base on Kerberos, so proposal is easy and fast about user authentication. This have simple procedures and more secure services against of PKI. So, our system can support secure multi-screen services against various security threats in multi-screen environments.
