In the TV broadcasting, movie production and business the transportation of video between creators (programmers, studios) and distributors (broadcast and cable networks, cable and satellites companies) is still a mix of File Transfer Protocol (FTP), physical delivery, and expensive multicast satellite. Cloud-based file sync-and-share providers like Dropbox and box are playing an increasing role, but the industry's unique demands for speed and multicasting have fueled the growth of IP Video transport. This paper gives a solid grasp of the major elements of IP video technology, including content preparation, system architecture alternatives and network performance management.

There are several data broadcasting standards that the developers should apply when develops any interactive digital TV contents. In Korea, we adopts ACAP(Advanced Common Application Platform) as terrestrial data broadcasting standard, MHP(Multimedia Home Platform) fur satellite data broadcasting and OCAP(OpenCable Application Platform) for cable data broadcasting. Therefore, content providers must develop different applications which suited for different standards - even if the application is exactly same. This is waste of time and energy. This paper suggests a solution to solve this problem among different broadcasting platforms - MHP, OCAP and ACAP. We compared these specifications, and found out what APIs are typically used far applications. Then we designed XML file structures that can be used to define contents of applications. We also implemented an authoring tool which automatically generates XML files by interaction with users. This paper also ascertains Xlet applications, produced by the authoring tool, works properly on each different data broadcasting standard - MHP, OCAP and ACAP.

최근 IT를 포함한 모든 산업 및 기술 영역에서는 포준화 활동을 기반으로 하여 융복합화(Convergence) 현상이 두드러지고 있다. 이는 또한 e-Learning 산업 및 기술에서도 큰 화두이다. 현재 e-Learning 표준화에서 시장에서 주도권을 행사하고 있는 것은 ADL의 SCORM 규격이다. 데이터방송 영역에서는, 북미에서 지상파와 케이블 TV간 콘텐츠 호환성 확보를 위해 ATSC와 케이블랩(CableLabs)이 공동 연구 중인 ACAP을 통해서 지상파-케이블 공통 표준화가 진행중이다. 이에 본 논문은 3-Learning 산업 및 기술에서의 융복합화의 일 영역으로 그리고 방송통신융합서비스의 일환으로 인터넷 기반 학습 환경과 TV 기반 학습 환경에서의 학습 콘텐츠 ( 및 코스웨어) 상호운용성에 대해 연구하였다. 이를 위하여 인터넷 기반의 e-Learning의 사실상의 표준으로 받아들여지고 있는 SCORM 규격과 DTV 환경 기반의 데이터방송 지상파-케이블 공통 규격인 ACAP간의 상호운용 API 개발을 통하여, SCORM 규격과 ACAP 규격의 상호운용성을 가능하게 하는 학습 콘텐츠 및 T-Learning 운용환경을 연구$\cdot$개발하였다.

D-CATV VOD service provides various contents such as drama and movie with high quality regardless of time and place. As the usage time of the VOD service increases, the viewing time of real-time terrestrial broadcasting is shortened. As the demand for VOD service is high and the number of digital users is increasing, the VOD market is rapidly growing. Therefore this study investigates the age and gender analysis of digital cable TV users and analyzed the usage patterns and audience cases of users. VOD service has been shown to be used by many users for the first time through remote control and free coupons. Non-users of VOD service did not use it because of charge and did not feel the necessity, but some non-users did not recognize the free VOD service.

The music video was produced by the multimedia type of a video clip by adding the image to match it with the release of audio recordings. mass production. Although originally it started as a means of promoting music as mere receive attention as the main content of the music cable broadcast M-TV began mass production. The 21st century has used the technology in various fields, including animated films and live action films, documentaries smart phone era. Among attempts to analyze their work tends to center the photographer and music video director Anton Corbijin and Stephen Sednaoui representing a photographic image of a music video

CAS(Conditional Access System) was developed for paid-for service in cable and fixed satellite broadcast system and technology and market maturity are high. However, these assessment is limited by CAS in fixed broadcasting system. In case of digital mobile broadcast such as T-DMB is difficult to apply CAS technology of fixed broadcasting system because of a use method and technology characteristic. Expecially, in case T-DMB using limited resources, a CAS message which must transmit in each service channel can cause problems. It is desirable that system transmits the CAS message which transmitted by each service channel through logical CAS message-only channel. In order to make a logical CAS message channel, we need a multiplexing techniques for CAS message using in each channel. In this paper, we design the CAS message multiplexing techniques for composition of CAS message-only channel.

Concerns have been growing about whether domestic internet protocol television (IPTV) can establish a solid foothold in the pay TV market, largely because of the lack of IPTV-only content and service differentiation. It has been difficult for IPTV providers to attract valuable PPs (program providers) to strengthen their positions, and IPTV providers have invested much money into procuring content. To survive this difficult situation, IPTV providers need to reappraise their profit sharing methods and content distribution structure to facilitate the expansion of their subscriber base. This can be done by attracting valuable PPs to IPTV providers and securing extra revenue by distributing more content for their PP partners. The IPTV industry has a different structure and value chain from the digital cable industry. Moreover, profit sharing schemes among participants in the IPTV industry are complicated. Thus it is essential to analyze the criteria for profit sharing, the selection of attributes in profit sharing, and their cause-effect relationship in developing fair pricing for broadcast content in the IPTV industry. This study introduces the attributes that need to be considered for the pricing of content and profit sharing among IPTV providers and PPs. In addition, this study uses system dynamics to analyze the relationship among those attributes along with additional associated factors for the pricing of content.

This paper proposes a signaling and multiplexing mechanism in service-compatible 3DTV broadcasting for guaranteeing backward-compatibility with legacy DTV. Recently, 3DTV experimental broadcasting services are being developed around advanced countries and the standardization of service-compatible 3DTV broadcasting which is able to provide high-quality stereoscopic videos in progress. Based on experimental results, we confirm that proposed method can be used as a common technology and a reference model for stereoscopic video transmission over terrestial, satellite and cable DTV platforms in 3DTV broadcasting service and system development.

Expand the market because the size of the huge funds administered by the conversion of over-the-air digital TV broadcasts in the current situation is likely to be reduced due to the influence of the media over-the-air broadcasts new paid media, digital cable TV and IPTV new mobile TV as a new growth engineis required. Broadcasting system to increase the supply and demand of the module from the ATSC-M/H DMB business existing in the domestic over-the-air broadcasters, has seen significant achievements in sleep technology with the introduction is expected. ATSC-M/H does not require a separate frequency allocation for mobile services does not interfere with the existing ATSC system simulcast, which can be performed on Android mobile handsets American-style mobile broadcast reception module to develop should. This paper is to design the software modules in the broadcasting module embedded systems that are applied on the Android platform, broadcasting from mobile handsets to see.

This paper introduces an development of high-definition(HD) 3DTV experimental broadcasting system and its experimental service that has been launched via three broadcasting network including terrestrial, cable and satellite in the late of 2010. This 3DTV experimental broadcasting service employs an innovative 3DTV broadcasting mechanism, called as dual stream method in which left and right images are encoded by using each video encoder and multiplexed using MPEG-2 system technology for guaranteeing backward-compatibility with legacy DTV. This paper specifically describes the developed experimental broadcasting system, concentrating on 3DTV re-multiplexer and 3DTV receiver. Finally, implementation and terrestrial 3DTV experimental broadcasting service results will be introduced from the point of objective and subjective evaluation.
