This study investigated a current situation of cable TV in order to seek and suggest cable TV's competitive superiority in the era of multiplatform media marketplace. This study suggested cable TV's direction from two aspects, short-term and mid and long-term strategies. As a result, it recommended that cable TV industry need to establish content circulation representatives, and reinforce multiformat contents suitable for various multiplatform uses, digital cable promotion, production of SO's originated programs, HD VOD, bundling services and diverse programs. As a long-term strategy, this study also suggested cable TV industry need to cooperate with smart TV industry in order to widen openness of its platform, and to provide not only diverse contents but also applications by offering two-way, mobile, and on-demand contents and services. Finally, this study proposed cable TV is needed to move towards a comprehensive media portal, which is a contents aggregator with the aforementioned business strategies.

With the advancement of the digital convergence of content and platform, Korean film industry sees good opportunities of maximizing the profits and increased distribution opportunities by independent film makers. Nevertheless, the domestic film market almost entirely relies on the box office sales, which seems to be caused by the stagnation of new additional copyright market. The study aims to address the following problems: First, information asymmetry of the revenues to which the contents providers and the service providers are exposed leads to the distrust among digital film contents businesses and the disadvantages to film makers and investors, in particular. Secondly, the VOD(Video on Demand) market of film industry is adversely affected by the illegal uploads and downloads of film contents, which harms the formation of paid additional market. Based on the examination of current legislation and policy options addressing these issues, the study suggests legislative accomodations and cultural industry policy alternatives to promote the additional market of film industry.

Recently, many kinds of TV contents based on multimedia need transmission systems without the saved. In this study, we develop the streaming device and smart app to transmit and play without store for multimedia contents such a broadcasting, internet, VOD, video, and animation. To do this, we compare and analysis main CPU products, broadcasting tuners and interfaces for streaming sources, and memory products. We then design and implement the streaming device which supports 30fps@FHD H.264 decoding and streaming, and multimedia sources with more than three. We develop the software for these requirements. Thissystemis useful to support billing service for multimedia contents.

In this study, the optimal buffer size is calculated for seamless video playback on a mobile device. Buffer means the memory space for multimedia packet which arrives in mobile device for video play such as VOD service. If the buffer size is too large, latency time before video playback can be longer. However, if it is too short, playback service can be paused because of shortage of packets arrived. Hence, the optimal buffer size insures QoS of video playback on mobile devices. We model the process of buffering into a discret-time queueing model. Mean busy period length and mean waiting time of Geo/G/1 queue with N-policy is analyzed. After then, we uses the main performance measures to present numerical examples to decide the optimal buffer size on mobile devices. Our results enhance the user satisfaction by insuring the seamless playback and minimizing the initial delay time in VOD streaming process.

This study aims to find out the influences of user behavior, content characteristics, functional factors and user's perception in cost on user satisfaction and continuous intention in N-Screen service. Web survey was conducted for 498 users who have used N screen service. The results show that the most influential factor contributing to user satisfaction is user interface. VOD diversity, payment system, cost, channel diversity are also meaningful factors. Identifying the critical factors which impact on user satisfaction, this study can provide the basic data for activating OTT service in smart media environment.

가상 채널을 통한 IPTV 인터렉션 디자인 -멀티미디어 컨텐트 소비를 중심으로 정해진 방송시간에 따라 일 방향적으로 프로그램 매제를 제공하던 TV 는 바야흐로 혁명의 시대를 맞고 있다. 이에 따라 사용자는 오랜 시간 기존의 TV 에서의 사용자 경험을 유지한 채, IPTV 라는 새로운 방식의 시스템을 경험하게 된다. 따라서 기존의 TV 사용자들도 이러한 새로운 형태의 TV를 거부감 없이 적극적으로 사용할 수 있도록 하기 위하여 사용자 중심의 인터렉션에 대한 연구와 인터페이스 개발의 필요성이 높아지고 있다. 본 연구에서는 현재 국내에 상용화된 IPTV 의 서비스들 중에서 주식, 쇼핑, 교통 등과 같은 양방향 서비스를 제외한 실시간 방송과 기존의 VOD 컨텐츠들을 포함한 멀티미디어 컨텐츠 소비에 대한 인터렉션 방법을 연구 범위로 정하였다. 본 연구를 위하여, 기존의 IPTV VOD 컨텐트의 소비 방식에 대해 다양한 사용자 리서치를 실시하였다. 그 결과 피 실험자들은 기존의 TV 에서 경험했던 것과 같이 단순하고 심플한 조작 방식으로 원하는 task 를 수행하여 각 목적에 맞는 결과를 얻는 것을 기대 한다는 것을 알 수 있었다. 그러나 실제 이 과정에서 피실험자들은 인터렉션 상의 여러 가지 문제점을 겪었는데, 특히 VOD 소비 방법의 accessibility 부분에서 해결해야 할 사용자 경험 요소들을 많음을 알 수 있었다. 따라서 본 연구를 통하여 현재 국내에 상용화된 IPTV 의 VOD 컨텐츠 소비 방식과 실시간 방송 컨텐츠를 소비함에 있어서 사용자가 만족하지 못하는 경험적 요소들을 집중적으로 연구하여, 기존의 TV 사용자가 더욱 적극적으로 멀티미디어 컨텐츠를 소비할 수 있는 방안으로 새로운 개념의 가상채널 인터렉션 방법을 제안하고자 한다.

The advancement of information technology along with the proliferation of communication and multimedia has increased the demand of digital contents. Video data of digital contents such as VOD, NOD, Digital Library, IPTV, and UCC are getting more permeated in various application fields. Video data have sequential characteristic besides providing the spatial and temporal information in its 3D format, making searching or browsing ineffective due to long turnaround time. In this paper, we suggest ATVC(Authoring Tool for Video Contents) for solving this issue. ATVC is a video editing tool that detects key frames using visual rhythm and insert metadata such as keywords into key frames via XML tagging. Visual rhythm is applied to map 3D spatial and temporal information to 2D information. Its processing speed is fast because it can get pixel information without IDCT, and it can classify edit-effects such as cut, wipe, and dissolve. Since XML data save key frame information via XML tag and keyword information, it can furnish efficient browsing.
