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.

Since Samsung SDI and Sony started mass production of AM-OLED display for mobile/TV applications, OLED technology has emerged as leading candidate among the many technologies under development for next generation Flat panel displays. P-OLED (Polymer Organic Lighting Emitting Diode) technology, a class of OLED, is gathering momentum towards commercialization. P-OLED technology has made tremendous progress in terms of display performance (including life time, efficiency and color gamut) and in the maturity of ink jet printing process and equipment. In order to get into the mobile/TV application market successfully, P-OLED display technology must meet the following display makers' requirements: (1) P-OLED Display Performance in terms of lifetime, efficiency, and color coordinates, (2) Low Cost Manufacturing Technology such as "Solution Processable Printing Technology". P-OLED technology has already overcome many of the hurdles to mass manufacturing. In this paper, the latest developments in ink jet printing technology, including P-OLED material performance, is discussed.

Recently, the use of mobile devices has increased, and mobile traffic is growing rapidly. In order to deal with such massive traffic, cognitive radio (CR) is applied to efficiently use limited-spectrum resources. However, there can be multiple communication systems trying to access the white space (unused spectrum), and inevitable interference may occur to cause mutual performance degradation. Therefore, understanding the effects of interference in CR-based systems is crucial to meaningful operations of these systems. In this paper, we consider a long-term evolution (LTE) system using additional spectra by accessing the TV white space, where low-power devices (LPDs) are licensed primary users, in addition to TV broadcasting service providers. We model such a heterogeneous system to analyze the co-existence problem and evaluate the interference effects of LPDs on LTE user equipment (UE) throughput. We then present methods to mitigate the interference effects of LPDs by 'de-selecting' some of the UEs to effectively increase the overall sector throughput of the CR-based LTE system.

This letter presents a CMOS RF front-end operating in a subthreshold region for low-power Band-III mobile TV applications. The performance and feasibility of the RF front-end are verified by integrating with a low-IF RF tuner fabricated in a 0.13-${\mu}m$ CMOS technology. The RF front-end achieves the measured noise figure of 4.4 dB and a wide gain control range of 68.7 dB with a maximum gain of 54.7 dB. The power consumption of the RF front-end is 13.8 mW from a 1.2 V supply.

Organic light-emitting diodes (OLEDs) have already been commercialized for the mobile-phone display, TV, and lighting panels. Even though the OLED display for the mobile phones is now considered as the main stream display for the application, the OLED TV and lighting panels are having difficulty in their market due to their high prices despite the better performance to the competitors. In recent years, roll-to-roll production of the OLED has begun to be examined, and this method is opening a way to solve the high price problem. In this article, we introduce several important processes for roll-to-roll production of OLED and explain the development status to date.

In this paper, an ATSC(Advanced Television Standard Committee)-M/H(Mobile/Handheld) multiplexer is designed and implemented using an embedded Linux based hardware platform. The ATSC-M/H multiplexer is composed of a CPU(Central Processor Unit), an FPGA(Field-Programmable Gate Array), ASI(Asynchronous Serial Interface)/SMPTE310(Society of Motion Picture and Television Engineers310) interface board, and a GPS(Global Position System) clock processing block. The main functions of the ATSC-M/H multiplexer executed in the CPU and FPGA are described. The operation of the ATSC-M/H multiplexer is verified by processing its broadcast signal on a commercial receiver analyzer.

Mobile ODF (one drop filling) portable display such as mobile phone and application product is needed high reliability than notebook, monitor and TV. Therefore, material development in order to optimize mobile & application ODF panel is needed. Through considering mobile ODF process and design, we have developed method of material matching test by several tests which is heat stress, UV stress and ODF process condition. So we have developed a material with characteristics of high reliability for mobile ODF panel.

have been transformed to many products and game of various platform as successful animation be making for 26 seasons. However past studies were concentrated on characteristic of as an TV animation series, almost never focused on transforming strategy. is showing distinguished strategy for how long living TV animation series can be made to user participating contents constantly. This paper analyzed a characteristic transforming strategy to game of as focusing on that EA company was made for mobile platform and it has been popular for a long time comparatively. So first we analyzed characteristic narrative of animation, and then searched how it is appeared to space managing simulation game . It will be helpful study how to build narrative strategy when TV animation series will be transformed to game as analyzing gamification process of .

As studies on ubiquitous computing are actively conducted, desire for various services, including image transmission storage, search and remote monitoring. has been expanding into mobile environment as well as to PCs. while CCTV (closed circuit TV) and un DVR (Digital video Recording) are used in places where security service such as intrusion detection system is required, these are high-end equipment. So it is not easy for ordinary users or household and small-sized companies to use them. Besides, they are difficult to be carried and camera solution for mobile device does not support high-quality function and provides low-definition of QVGA for picture quality. Therefore, in this study, design and implementation of embedded system of high-definition image transmission for ubiquitous mobile device which is not inferior to PC or DVR are described. To this end, usage of dedicated CPU for mobile device and design and implementation of MPEG-4 H/W CODEC also are examined. The implemented system showed excellent performance in mobile environment, in terms of speed, picture quality.
