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.

DMB data broadcasting has recently come into the spotlight as a platform for a new business opportunity and an application of various contents. This paper estimates the willingness to pay for the DMB data broadcasting services and explains the demand characteristics for TPEG, BIFS and BWS services, using the Double-bounded dichotomous choice Contingent Valuation Method. Consumers are willing to pay 2,039 Korean won for TPEG service and 1,612 Korean won for BIFS and BWS services per month, which corresponds to the market size 87.6 billion Korean won for TPEG and 195.2 billion Korean won for BWS and BIFS a year respectively. It is also found that the more consumers show usage intentions, have experiences in the similar services, and know of the DMB data broadcasting services, the more they are likely to pay for the DMB data broadcasting services.

In this paper, we present an intellectual property management and protection (IPMP) system in a broadcasting environment to provide mechanisms for copyright and contents protection that are compliant with the MPEG-2 and MPEG-4 IPMP Extension (IPMPX) specifications. The technology for processing IPMP related information was exploited, and a terminal model has been successfully designed and implemented. In addition, interoperability, which is the main objective of MPEG-2/4 IPMPX, has been addressed in detail. The experimental results show that the implemented system performs the IPMP process well, meeting the requirements of a broadcasting environment.

최근 인터넷에서 많은 관심을 보이고 있는 개인 미디어(UCC;User Created, Contents, VC2;Viewer Created Contents, 이하 UCC-사용자가 직접 제작한 미디어 콘텐츠를 불특정 다수에게 제공하는 서비스) 중에 비디오/오디오 콘텐츠를 영상 콘텐츠의 기본적인 매체라 할 수 있는 TV상에서 직접 즐길 수 있다면 미디어의 대상과 그 미디어의 Entertainment적인 효과는 배가될 것이다. 디지털 케이블 방송에서 UCC와 같은 다양하고 많은 미디어 콘텐츠를 디지털 TV상에서 서비스를 하고자 한다면 현재의 OCAP(OpenCable Application Plat form)기반에서는 RVOD(Real Video on Demand)와 동일한 서비스 모델을 가져야 하는 부담과 UCC 제공을 위한 방송 플랫폼별 인터페이스가 필요할 것이다. 이러한 문제점을 Return Path를 통한 RTP(Real-time Transport Protocol;RFC1889)을 이용해서 기존의 VoD(Video on Demand)스트림의 대역에서 분리하고 별도의 VOD프로토콜을 구현함으로써 라이브 방송환경과 동일한 인프라의 지속적인 확장보다는 일반적인 네트워크 프로토콜을 이용하여 VoD서비스를 위한 인프라에 많은 영향을 받지 않는 서비스가 가능할 수 있을 것이다. 따라서 본 논문에서는 RTP를 위한 Set-Top-Box상의 다운로드 가능한 구조의 클래스 분석과 클라이언트 대응의 UCC Transcoding 및 전송을 위한 스트리밍 서버의 설계에 중점을 두고 경량화 된 VOD서비스 및 시스템을 설계함으로써 방송환경 하에 On-Demand서비스의 효율적인 확장성과 보다 많은 콘텐츠 등록 및 활용의 기회를 가져올 수 있을 것으로 기대한다.

The research is centered towards analyzing the differentiation of the characteristics and organization of programming strategy and channel positioning by selecting Korean International Public Relations Broadcasting Stations Arirang TV and KBS World. According to the results, Arirang TV positions Korean culture content-implied educational programs as their strategy while KBS World places the main programs of KBS1, 2TV with many entertainment programs such as dramas and entertainment shows. Arirang TV's programming strategy is well-fulfilling the purpose of promoting Korea's culture contents by organizing their programming with documentaries, tourist information, and daily living information. On the other hand, KBS World works as the agent of the spread of the Korean Wave by filling their program with dramas and K-pop programs such as . Due to the difference in programming strategy of these two broadcasting stations, Arirang TV has positioned itself as a diplomatic channel to spread Korean culture and KBS World a channel representing the Korean Wave. However, there are problems of inefficiency due to recurrent investments because of the fact that both broadcasting stations' programming strategy is to promote Korean culture and spread the Korean Wave by aiming similar targets such as foreigners or overseas Koreans.

Under the recent trend of telecommunications and broadcasting convergence, much more various forms of new convergence broadcasting services are being introduced than ever before. Owing to the unique advantages, new convergence broadcasting services are expected to bring drastic changes to the current broadcasting service market. In this research, we attempt to examine what kind of attributes critically affect the competition among new convergence broadcasting services, and how much competitive they will be, based on the quantitative information about consumer preferences for the important attributes of new convergence broadcasting services. Conjoint survey was used in order to obtain stated preference data of consumers. From the results, some implications are obtained as follows. First, even though new convergence broadcasting services have many unique advantages, still price is the most important for the consumers. Second, it is expected that considerable consumer valuation exists for the unique advantages of new convergence broadcasting services like mobility and dual-way interactivity, which will add the competitiveness of those services in the future. Third, since midterm advertising puts negative utility on consumers, broadcasting services with midterm advertising will not be preferred to those with neither advertising nor midterm advertising. Fourth, service coverage and the number of consumers using the same broadcasting service have a significant feedback effect on the competition between broadcasting services from the dynamic aspect. Lastly, the consumer preference can be affected by demographic variables like age and gender, and broadcasting service usage patterns such as channel switchover for escaping advertisement and frequency of using other recorded media. Main findings of our research might become useful information for both telecommunication and broadcasting companies, contents providers, advertisers, and policy and regulation makers to cope with the uncertain environment of telecommunication and broadcasting convergence.

This study tried to examine the validity of the technical and institutional method to perform the purpose of public interest in terrestrial broadcasting. For this purpose, this study concentrated to the rate of direct reception of the terrestrial broadcasting that government and broadcasting company have offered since the digital transition. Results of analysis, it appeared that have not possibility of realization to set the direct receiving antenna and built-in Antenna for enhanced reception of the signal of the terrestrial broadcasting. Second, the MMS, if not enhanced the direct reception, was expected that repeated the retransmission through the pay broadcasting as the time of digital transition. Finally, the disaster broadcast was revealed that reduce the effectiveness of the UHD TV policy because of the mutual interference between frequencies and the incomplete solution of shadow area. According to these results, it is expected to be difficult for a while to perform the purpose of public interest in UHD TV.

This paper presents the design of a broadcasting scenario and system for an 8K-resolution content. Due to an 8K content is four times larger than the 4K content in terms of size, many technologies such as content acquisition, video coding, and transmission are required to deal with it. Therefore, high-quality video and audio for 8K (ultra-high definition television) service is not possible to be transmitted only using the current terrestrial broadcasting system. The proposed broadcasting system divides the 8K content into four 4K contents by area, and each area is hierarchically encoded by Scalable High-efficiency Video Coding (SHVC) into three layers: L0, L1, and L2. Every part of the 8K video content divided into areas and hierarchy is independently treated. These parts are transmitted over heterogeneous networks such as digital broadcasting and broadband networks after going through several processes of generating signal messages, encapsulation, and packetization based on MPEG media transport. We propose three methods of generating streams at the sending entity to merge the divided streams into the original content at the receiving entity. First, we design the composition information, which defines the presentation structure for displays. Second, a descriptor for content synchronization is included in the signal message. Finally, we define the rules for generating "packet_id" among the packet header fields and design the transmission scheduler to acquire the divided streams quickly. We implement the 8K broadcasting system by adapting the proposed methods and show that the 8K-resolution contents are stably received and serviced with a low delay.
