It is said that the highlight in the media covergence and integration within digital environment era is 'Contents'. Due to the advent of new media and various covergence and integration services, the competition between the platforms has become aggressive. As a result, it is predicted that the negotiation power of a 'Content's industry will be strengthened. In reality, the actual environmental changes in the media environment have accompanied elements of industrial crisis rather than opportunity to expand the market. The changes are especially causing sales structure distortion and proceeds deterioration in the Korean film industry. Moreover, telecommunication and broadcasting businesses are making their entrance into the film industry, through the appearance of the media covergence and integration as a backdrop. Thus, the situation that the Korean film industry is facing is closely associated with the development of the digital technology and new media environment. Eventually, weathering the crisis and pioneering the future will be possible through changes in the media environment. The purpose of this study is to show how the media covergence and integration phenomenon is occurring in the film industry. This study will also focus on what new problems are occurring as a result, and seek out the solutions that are available.

In this paper we propose the structure of MPEG-4 multimedia player platform for Terrestrial Digital Multimedia Broadcasting (DMB) Service. Korea will launch DMB service at next 2004 you based on Eureka-147 Digital Audio Broadcasting (DAB) Service System. This new mobile multimedia broadcasting services provide not only high quality digital audio broadcasting services, but also various multimedia data broadcasting services including high quality video. For the sake of MPEG-4 Systems technologies, it will provide an interactive service to users in the near future. Therefore it terminal shall have various functionalities as well as playing audio-visual contents. However there is no precedence standard for such mobile interactive multimedia broadcasting system. Therefore it is very import to provide the multimedia player platform of DMB service for accelerating the development process of commercial terminal and providing a direction of next DMB terminal structure.

This study deals with the technical approach related to the protection of digital video contents copyright, which has currently become a major issue in the digital contents market. With the production and distribution of digital video contents rapidly increasing, various policies and technical approaches are being made in relation to the protection of intellectual property rights. The technical approach from a DRM (Digital Rights Management) perspective was made from various angles, but its limitations have also been exposed in terms of convenience and quality. In this study, rather than the existing encoding certification and watermark technologies, it introduces technical approaches from a content-based copy detection method, while suggesting a copy detection method using the representative color sequence. In particular, this study takes into consideration the distribution environment of the domestic video market and deals with the technical approach in a direction that can control the illegal distribution of high quality videos.

대용량 콘텐츠에 대한 관심이 증가함에 따라 지상파 방송의 전송용량을 증가시키기 위한 다양한 노력들이 시도되고 있다. 미국의 표준화 단체인 Advance Television Systems Committee(ATSC)에서는 초고화질의 데이터 전송이 가능하고 동시에 HD급 이동방송 서비스가 가능한 차세대 방송방식인 ATSC 3.0의 표준화 완료를 목표로 현재 막바지 작업을 진행하고 있다. 본고에서는 ATSC 3.0으로 불리는 ATSC 차세대 방송방식의 물리계층에 대한 표준화 동향과 ATSC 3.0 물리계층의 한 축을 담당하고 있는 프레임 동기를 위한 부트스트랩, Constellation 및 Layered Division Multiplexing(LDM) 기술에 대해 살펴보고, 물리계층의 획기적인 전송용량 증대 기법인 Multiple Input Multiple Output(MIMO) 기술에 대해 정리하고자 한다.

애니메이션 편성시간대를 6시대에서 4시30분대로 옮기려는 KBS의 시도가 업계의 거센 반발에 직면해 일단 무산되기는 했지만, 애니메이션 방영시간의 안정적인 확보를 위해서는 현행 방송법을 개정해야 한다는 목소리가 높아지고 있다. 이를 위해 애니메이션 제작자협회 · 애니메이션예술인협회 · 만화애니메이션학회 · 출판만화협회 · 우리만화연대 · 만화가협회 등 6개 관련 단체와 만화가 등 애니메이션 업계는‘방송용 애니메이션 발전전략 촉구 및 개정을 위한 범 만화 · 애니메이션계 공동대책위원회’를 발족, 애니메이션 발전을 위한 대책 강구에 나서고 있다. 공대위는 지난해 11월 초에는 방송 애니메이션 총량제를 강화한 방송법 개정안의 연내 통과와 방송사의 애니메이션 편성 정책 시정을 촉구하는 집회도 열며 총력전을 벌이고 있다. 하지만 지난해내 입법화를 기대했던 애니총량제는 방송법 개정 지연으로 불투명해진데다 최근 들어 중국 · 일본 정부가 강도 높은 애니메이션 육성책을 추진하고 있을 뿐 아니라 제4차 일본 문화개방도 이어지고 있어 국내 애니 업계의 위기감은 더욱 거세지고 있다. 신성장산업인 애니메이션 산업 활성화를 위해서는 애니총량제 등의 법 · 제도적 장치가 마련돼지 않으면 국내 애니메이션 산업은 더욱 깊은 수렁으로 빠질 것이라 게 업계의 공통된 시각이다.

방송시스템의 환경변화는 SDTV에서 HDTV, UHDTV로 방송콘텐츠 데이터 용량이 실감미디어를 향하여 크게 증가 하는 추세이다. 디지털방송 환경에서 파일 Encoding이 종료된 후 Transcoding 등의 미디어 처리 Process를 수행하면 대기 시간이 데이터 용량에 따라 증가할 수 밖에 없다. 따라서 본고는 기존의 Media Process 처리시 장시간의 대기시간을 절감하기 위한 방안으로 Encoding과 동시에 Transcoding, Quality Checking, Scene Detecting 등의 Media Processing 작업을 동시에 수행함으로써 사용자의 대기 시간을 최소화 할 수 있는 방법을 실험을 통하여 워크플로우 개선 방안을 제시한다.

This paper proposes a new personalized mobile advertising service using a smartphone connected with a digital signage which is increasingly common for out-of-home advertising. The advertising contents can be transferred with their metadata to a digital signage. Then, the signage delivers only metadata to smartphones in close proximity of it. Based on the user's preference, an application on a smartphone stores advertising metadata and publishes a personalized advertising e-catalog automatically. A smartphone user can browse, edit and share it with friends. In the view of extension of the reach of the advertising contents of various N-Screen devices including a digital signage and a smart TV to a smartphone and supplying personalized advertising data, this advertising model will be very beneficial and commercialized in the near future.

Digital cinema based on digital master distribution increases with stereoscopic film as the center. DCI specification V1.0 announced at 2004, it considerates stereoscopic film screening. And now, the Society of Motion Picture and Television Engineers is establishing a task force to define the standards of a stereoscopic contents viewed in the home. Today, most Hollywood commercial stereoscopic film features animation using computer graphic. However, considering film making characteristic, stereoscopic digital cinema is required shooting in real world and editing, screening. This paper presents possibility of stereoscopic examination at NLE in the stereoscopic workflow. And we will propose new stereoscopic digital cinema workflow to apply the stereoscopic examination. Based on experimental results, the 3D ready television using 120Hz has some obstacles for contents editing, but most domestic stereoscopic monitor using circular polarization is possible for successful editing.

복제방지 기술은 저작권이 있는 소프트웨어, 영화, 음악 등에 대해 불법적인 재생산을 막기 위한 기술적보호조치 중의 하나이다. 기술적보호조치를 우회하거나 무력화하는 행위에 대해서는 법에서 금지하고 있으며, 효과적이고 상당한 수준의 기술적보호조치가 요구되고 있다. 현재까지 인터넷 기반의 PC플랫폼을 중심으로 발전되어 왔던 복제방지 기술도 디지털 방송 및 다양한 휴대 기기의 발달과 이용 형태의 변화에 따라 복제방지 기술 또한 다양한 요구사항을 만족시키기 위한 보호기술로 확장되어 왔다. 소프트웨어 및 디지털 콘텐츠 제작자들은 좀 더 자극적이고 능동적이고 불법 복제 및 유통을 차단하기 위하여 복제 방지기술을 도입하고 있으며 MP3폰, 셋탑박스 등에 필수적으로 탑재되고 있다.

The enforcement of the digital switch been two years, but more than half of the viewers are still not enjoying the benefits of it. Therefore, the government proposed that 8VSB transmission method so that majority of the viewer is able to enjoy the benefits of a digital switch. However, the claim has been suggested that 8VSB transmission method will have negative impacts on broadcast market feedback. In this regard, this study verified the effect of 8VSB and the method of minimization on the broadcast market. This study has conducted in-depth interviews concerned experts to achieve this purpose. Results of an interview revealed that the negative impact on the market of content and platforms, network is very small. In other words, the majority of the experts argued that the policy of government about 8VSB transmission are inadequate and it is improved to broaden the choice of the broadcast consumer.
