Mass culture is product of media technology. We are absorbing and surround in optical image which reflex medium emits by night and day continually specially and live culture and information produced infinitely through mass media. People discharging in main living room now to remote control a television manufacture because carrying out move freely and is preoccupied with object of interest that have been spread in a television, and assimilate all image like sponge. Reflex medium contacted habitually every day whether do not want even if want can do that populace cultural personality is much stronger as subject that make actuality of processing.

In recent years, with the continuous innovation and upgrading of engine software, the real-time rendering technology in film and television has been continuously improved, and the virtual production technology has also developed rapidly. This paper introduces the green screen often used in traditional film production and a virtual production technology based on light-emitting-diode background wall that was proposed and implemented last year. We analyzed the two production methods of virtual production and compared their characteristics. Based on these results, we can better understand the differences and respective advantages of the two production methods. And we also can according to the production budget, production cycle and the creative and technical capabilities of the team make better choices during the production process. We believe virtual production technology will be production in the future to provide a more solid technical guarantee for the development of the film industry, and this work will pave the way for further research on virtual production technology.

Photoconductive target was fabricated to make vidicon available. In order for a vidicon to operate well, it is essential that the target have high photosensitivity, low image lag, and high resolution. In the vidicon mode analysis, photosensitivity of 0.8, image lag of 30%, resolution of 300 TV lines, and the S/N ratio of 30 dB at 10 lux illumination were measured.

In this letter, the constant driving power reduction ratio has been achieved for column drivers regardless of the input image by incorporating a new static power reduction scheme into the previous dynamic power reduction method. The measured power reduction ratio is around 50% for a 120 Hz liquid crystal display panel in such cases of still input video and fallback.

Digital TV tuner for 8-VSB modulation was developed with satisfying the requirements of ATSC. The double frequency conversion and the active tracking filter in the front-end were used to reduce interference of the adjacent channels and multi-channels, which suppress If beat and image band. However, it was impossible to get frequency mapping between tracking filter and first VCO(Voltage Controlled Oscillator) in the double conversion digital TV tuner differing from conventional NTSC tuner. This paper, therefore, suggests the available structure and a new method for automatic frequency selection by obtaining the mapping of frequency characteristic over tracking voltage and the combined hardware which compose of Micro-controller, EEPROM, D/A(Digital-to-Analog Converter), OP amp and switch driver to solve above problems.

According to increase of preference to the large display device, demand of a three-tube projection TV increase in the display market. But luminance per unit area of a 3-tube projection TV is less bright than that of original one -tube TV The color gamut of phosphor used in the projection TV is different to standard gamut of phosphor in NTSC. In this paper, we analyze the relationship between coordinates of RGB phosphor and RGB beam currents according to the color temperature in projection HDTV. We also proposed the range of reference white which maximize the luminance that viewer feel based on both Helmholtz-Kohlrausch effect which is visual property and degradation of image according to the change of beam profile by current-ratio.

As a method to compensate the deterioration of the picture quality which was caused by beam profile characteristic in the CRT and the projection screen of HD projection TV, a linear scan velocity modulation(SVM) method has been employed, whose modulation velocity is linearly proportional to the variation in the video signal amplitude. However, the effect of picture quality improvement is not uniform with video signal amplitude in the linear SVM. In this paper, for the optimum SVM effect, we analyze the beam profile characteristic on the HD projection screen and we analyze the SVM effect as function of the differentiated pulse width, the differentiated pulse amplitude and the input signal amplitude. Finally we confirm that the nonlinear SVM method is necessary to get uniform image compensation in the HD projection TV, and we implement the nonlinear SVM circuit. The performance of the realized SVM circuit with nonlinear amplitude transfer characteristic is confirmed as uniform improvements in picture quality.

This monograph was probed effectively by using practical methods in a subjectivity study that was accessible in depth, departing from bygone behavior of functional quantity analysis of awareness and the opinions of young people about the general (public) model of TV advertising. The perception patterns resolved in this study sorted out four types in a Q-methodology. The result is divided as follows: 1 [(N=7): Advertising Consensus Type], 2 [(N=7): Advertising Negative Type], 3 [(N=5): Advertising Purchasing Reduction Type], and 4 [(N=1): Advertising Persuasion Orientation Type]. As such, we found very different types all over. Finally, this study reviews subjective acceptance as to the type of model reception with regard to general TV advertising, offering a developmental suggestion on the issue, and an agenda about it.

The purpose of this study was to research into TV makeup types focusing on Korean aesthetics with recognizing importance of Korean thought amid what the global interest pays attention to South Korea thanks to the recent influence of Hanryu(Korean wave). The following are summary and result of this study. The non-dual beauty is an integrative concept of including ambivalence on the categorical difference in sex, culture and class by transcending the extreme binary division. As this is what reflected the open thought of pursuing balance of yin and yang in Korean people, it is being shown in the form of transcendence and far-outness through TV entertainment programs. Transcendence coexisted with maintaining relative relationship beyond separation in sex. Far-outness was pursuing free sensitivity immanent in the non-separated thought of transcending the past, the present and future. This trend is being indicated similarly to a change in its paradigm from separation to convergence these days. Accordingly, even makeup was showing similarity to the recent trend with being paid attention to the makeup of focusing on identity in sex and to the makeup of being coexisted the past, the present and future with the aspect of being mixed space time. The Korean aesthetics has been feeble in its influence compared to the Oriental image of focusing on China and Japan in the meantime. Hence, this study can be said to have significance in a sense of being the first consideration that compared TV makeup types of focusing on Korean aesthetics and suggested its developmental direction.

Success of brought a large revolution in the world of cinema and the media market. They have predicted new industrial possibility for 3D Stereoscopic image and trends started to support for producing in the field of various media platform. We can see our domestic technology creates higher added value in the sphere of hard-wear for the market of worldwide home TV electronics. But in reality we are short of effective and organized pipeline of producing and we should analyse cases more for Stereoscopic 3D animations. Therefore in this paper, we present case study on animation made into Stereoscopic 3D animation to build up suitable Stereoscopic 3D TV animations pipeline. We differentiate from any other Stereoscopic content by applying artistic elements and technological elements, especially human factor and 3D Sweetening to elevate the level of 3D Stereoscopic effect for main audience, children. We propose how to strengthen the competitiveness of Korean animation for world animation market.
