A dispute over price for retransmitting terrestrial channels between Terrestrial Television Systems and Cable TV System Operator(SO)s has been underway up to now since 2007 and expected to last unless there is a measure of extraordinary countermeasures. Thus, in this paper, we present a scheme for calculating the reasonable price on retransmitting terrestrial channels. Re-transmission price calculation scheme is presented in two ways. One is to calculate the price for the extent to which Terrestrial broadcasters and Cable broadcasters contribute, and the other is to calculate the price for terrestrial channels retransmitted by applying the method of Cable TV PP program fee basis. In addition, on profit-sharing scheme and criteria for program fee we present two ways of subscription, which are flat sum system and fixed rate system.

As the subscribers of the digital cable and IPTV broadcasting are increasing, the VOD service has established a solid foothold as a profit model of the broadcasting industries. And what's more, the VOD service is emerging as a key application of the N-screen technologies. In the circumstance, broadcasting companies are trying to provide mobile services to improve the satisfaction of their VOD services usage. The paper introduces a VOD mobile app (of a domestic digital cable broadcasting), which includes the functions of promoting the VOD programs printed on a VOD guide book, directly transmitting the information (e.g., book-marking, remote-control signals) generated by the VOD mobile app to a set-top box, and watching the video contents stored in the mobile device on TV.

As the community antenna television (CATV) networks becomes ubiquitous, instead of constructing an entirely new broadband network infrastructure, it has emerged as one of the rapid and economic technologies to interconnecting heterogeneous network to provide broadband access to subscribers. How to support ubiquitous real-time multimedia applications, especially in a heavy traffic environment, becomes a critical issue in modern CATV networks. In this paper, we propose a time guaranteed and efficient upstream minislots allocation algorithm for supporting quality-of-service (QoS) traffic over data over cable service interface specification (DOCSIS) CATV networks to fulfill the needs of realtime interactive services, such as video telephony, video on demand (VOD), distance learning, and so on. The proposed adaptive fast expansion algorithm and the loading statistics with dynamic swapping algorithm have been shown to perform better than that of the multimedia cable network system (MCNS) DOCSIS.

Digital cable TV(DCATV) is totally different with a existing TV which is passive, and can pick the contents anytime we want. It is very popular in many houses and we can see bright future with this. This study will show a standard that is a suitable and convenient VOD menu category for 20's through a various usability test. Moreover it will be provided new menu style and GUI through the preferences. For this, we found expected problems first through the heuristic analysis and did iterative usability test to verify and improve these problems. As a result of that, we improved errors of VOD menu structure and suggested new menu style including metaphor, colour and icon users can recognize easily. That is, VOD categories should be grouped among definite meanings. And we found using convenience is more important than new discovery of method on menu style for experienced users. This study can be not only based data when DCATV menu is renewed but also can be used as a reference data when designing other DCATV menu.

This paper presents an integrated low noise and highly linear wideband RF front-end for a digital terrestrial and cable TV tuner, which are used as a part of double-conversion TV tuner. The low noise amplifier (LNA) has a low noise figure and high linearity by adopting a noise canceling technique based on current amplification. The up-conversion mixer and SAW buffer have high linearity by employing a third order intermodulation cancellation technique. The proposed RF front-end is designed in a $0.18{\mu}m$ CMOS and draws 60 mA from a 1.8 V supply voltage. The RF front-end shows a voltage gain of 30 dB, an average single side-band noise figure of 4.2 dB, an IIP2 of 40 dBm, and an IIP3 of -4.5 dBm for the entire band from 48 MHz to 862Hz.

IPTV is referred to the service which provide integrated IPTV services for providing video, 10/100-Mbit/sec Internet, voice, video-on-demand (VOD), and other broadband applications including home security, video conferencing, and telemedicine. All services are integrated into an IP (Internet Protocol) architecture designed specifically for Gigabit Ethernet FTTH systems, HFC or xDLC. It is absolutely necessary that telecon operators provide IP video delivery platforms that enable service providers to transform their business. With their own products, they can better manage their existing services and generate new revenues from broadcast TV, movies on demand and multimedia. Triple-play is a combination of broadcast, telephony and broadband services offered through IPTV networks. With cable operators allowed to offer a triple-play bundle, the nation's telecom operators are beginning to get a little anxious. Cable operators assert that triple-play is a must-have and natural extension of the cable service bundle. The Korean Cable TV Association asserts that the triple-play model is of paramount importance to the cable industry's future growth. But the telecom sector considers itself unfairly disadvantaged, saying they cannot compete until regulatory issues are resolved. The start of web-based television in Korea may still be some time off with a confrontation between the nation's IT regulator and broadcasting sector over the service's legal boundaries shows no signs of being resolved my time soon. korea should be is the fastest-growing provider of IPTV solutions in the industry, with over worldwide customers.

최근 IT를 포함한 모든 산업 및 기술 영역에서는 융복합화(Convergence) 현상이 두드러지고 있으며, 이와 같은 현상은 모바일 시장을 필두로 방송 시장에도 본격적으로 도입 및 확산되는 추세이다. 현재 모바일 분야에서 플랫폼 기반으로 스마트폰 생태계를 주도해 온 구글 애플이 구글 TV iTV 등을 통해 스마트 TV 영역으로 플랫폼 확산을 추진 중이며, 삼성전자 LG전자와 같은 기존 TV 제조사들도 자체 개발 플랫폼을 기반으로 하여 스마트 TV 플랫폼 확산을 추진 중이다. 하지만, 각 제조사 및 유료방송 사업자별로 독자 플랫폼 기반의 독자 앱스토어 구축 시도로 인해 시장 파편화 현상(각기 다른 플랫폼 제공, 플랫폼별 제한적인 가입자 기반의 앱 및 개발자 부족, 차별화된 콘텐츠 부족)으로 인해 스마트TV 앱 생태계 구축에 있어서 글로벌 업체와 경쟁할 수 있는 규모의 경제 확립이 불가능한 상황이다. 이에 본 논문은 국내 케이블 방송 사업자들의 스마트 플랫폼 준비 상황 및 앱 생태계 구축 및 활성화를 위한 공동 앱스토어 추진 현황에 대해 연구하였다. 이를 위해 각 케이블 가입자가 채택한 스마트 플랫폼별 주요 특징, 공동 앱스토어 구축을 위한 표준화 진행 현황, 앱스토어 구축 현황 및 계획을 정리하였다.

In this paper, we design and implement verification and interface application for interactive data broadcasting middleware. This application implements ACAP and OCAP verification item according to their types (format, protocol. resource, presentation). Therefore, using this application, we can verify whether digital settop-boxes used in digital terrestrial television and digital cable television conforms to the ACAP and OCAP standards. In this paper, we evaluate our proposed application using TVPLUSiTM verifier which can verify interactive TV application in real broadcasting environment. Through performance evaluation, we show that the DTB-H650F set-top-box supports OCAP and ACAP standard 80% and 95%, respectively.

The recent growth of cable broadcast technology such as Tru2Way enables the cable service operator to provide more enhanced experiences to cable TV audience. As a result, various applications have been produced and user can easily access cable network to receive multimedia content as well as interactive application in cable environment. In order for current cable technology to be accepted as a web extended technology, a process of web based applications having a web document and multimedia resources, proper web service definition and middleware architecture for existing cable environment should be established. In this paper, we define a web application for cable environment and propose a middIeware architecture which can process web application based on Tru2Way technology
