The purpose of this study is to explore how South Korean TV news programs represent the image of North Korean defector through analyzing South Korean TV news contents portraying North Korean defector. In order to conduct this research, the study analyzes the main subjects of the South Korean TV news contents, the image of characters on the TV news contents, and frames which the TV news contents mainly used. According to the results of this study, the TV news programs represent the positive image of South Korean government whereas they criticize North Korean government while representing North Korean defector issues. However, the TV news programs showed no interest in real problems which the North Korean defectors are experiencing. Further, the findings of this study are very similar to the results of previous studies that were analyzing the representation of news media about minority groups including North Korean defectors. Most studies analyzing how news media represent minority groups show that the groups have been identified not by their own opinions and relations but predominant culture and lifestyles in the society, and they are also represented not by their own voice but predominant perspectives of the society.

This study is based on the screen composition(shot size, split screen, candidate placement, lighting, stage) that fits the discussion process (round table, sitting, standing method) adopted from the 19th presidential candidates' TV joint discussion to analyze the adequacy and limitations of the methodology(design, candidate background, etc.). In addition, the progress and screen composition of the 45th US Presidential Candidates Debate in 2016 and the 25th Presidential Candidates of France TV Joint Debate in 2017 have been analyzed to compare and contrast the methods used in Korea. Through this, we apply the screening method to the 20th Presidential Candidate TV Joint Debate, which will be held in 2022, to fit the fixed discussion process that can fully identify candidates' qualities, policies, and vision.

In this paper, we presents visual effect(water, fire, smoke) simulation and interaction system for TV virtual studio. TV virtual studio seamlessly synthesizes CG background and a live performer standing on a TV green studio. Previous virtual studios focus on the registration of CG background and a performer in real world. In contrast to the previous systems, we can afford to make new types of TV scenes more easily by simulating interactive visual effects according to a performer. This requires the extraction of the performer motion to be transformed 3D vector field and simulate fluids by applying the vector field to Navier Stokes equation. To add realism to water VFX simulation and interaction, we also simulate the dynamic behavior of splashing fluids on the water surface. To provide real-time recording of TV programs, real-time VFX simulation and interaction is presented through a GPU programming. Experimental results show this system can be used practically for realizing water, fire, smoke VFX simulation and the dynamic behavior simulation of fish flocks inside ocean.

Recently,IP-based broadcasting systems,such as Mobile-TV and IP-TV, have been widely deployed. These systems require a security system to allow only authorized subscribers access to broadcasting services. We analyzed the Conditional Access System, which is a security system used in the IP-based Pay-TV systems. A weakness of the system is that it does not scale well when the system experiences frequent membership changes. In this paper, we propose a group key distribution protocol which overcomes the scalability problem by reducing communication and computation overheads without loss of security strength. Our experimental results show that computation delay of the proposed protocol is smaller than one of the Conditional Access System. This is attributed to the fact that the proposed protocol replaces expensive encryption and decryption with relatively inexpensive arithmetic operations. In addition, the proposed protocol can help to set up a secure channel between a server and a client with the minimum additional overhead.

As smart-phone usage increases, the number of Social Networking Service (SNS) users has also exponentially increased. SNS allows people to efficiently exchange their personal opinion, and for this reason, it is possible to collect the reaction of each individual to a given event in real-time. Nevertheless, new methods need to be developed to collect and analyze people's opinion in real-time in order to effectively evaluate the impact of a TV advertisement. Hence, we designed and constructed a system that analyzes the effect of an advertisement in real-time by using data related to the advertisement collected from SNS, specifically, Twitter. In detail, Hadoop is used in the system to enable big-data analysis in parallel, and various analyses can be conducted by conducting separate numerical analyses of the degrees of mentioning, preference and reliability. The analysis can be accurate if the reliability is assessed using opinion mining technology. The proposed system is therefore proven to effectively handle and analyze data responses to divers TV advertisement.

In this paper, it is implemented the monitoring system for TV advertisement using video watermark. The functions of an advertisement monitoring system are automatically monitoring for the time, length, and index of the on-air advertisement, saving the log data, and reporting the monitoring result. The performance of the video watermark used in this paper is tested for TV advertisement monitoring. This test includes LAB test and field test. LAB test is done in laboratory environment and field test in actually broadcasting environment. LAB test includes PSNR, distortion measure in image, and the watermark detection rate in the various attack environment such as AD/DA(analog to digital and digital to analog) conversion, noise addition, and MPEG compression The result of LAB test is good for the TV advertisement monitoring. KOBACO and SBS are participated in the field test. The watermark detection rate is 100% in both the real-time processing and the saved file processing. The average deviation of the watermark detection time is 0.2 second, which is good because the permissible average error is 0.5 second.

As more consumers avoid ads aided by advanced technologies that conveniently block ads, traditional advertising is becoming less effective than ever before. Product placements are increasingly executed to unobtrusively expose products and brands to consumers while they watch media programs. The current study attempts to enhance our understanding of the factors that affect consumer attitude towards the brands placed in TV dramas. In particular, this study examines whether the attractiveness of actors and the congruency between the products placed and the story of the TV drama influence consumer attitudes towards the TV drama and the brand. A total of 211 male consumers in their 20s and 30s were used for data analyses. Structural equation modelling revealed that the product-story congruence had a positive impact on consumer attitude towards the TV drama as well as their attitude towards the brand. Actor attractiveness (in terms of similarity and likability) positively influenced consumer attitude towards the brand. Only the perceived likability dimension of actor attractiveness was found to affect consumer attitude towards the TV drama.

The main purpose of this study was to examine TV viewers' behavior on receiving family-related images reflected in soap operas and find the relationship between TV viewers' family-related value and TV viewers' behavior on receiving family-related images reflected in soap operas with empirical data. The data were collected from 500 adults aged 20-49 living in Seoul area for 3 days(January 17 to 19 of 2006). Statistical methods used were frequency, percentage, regression analysis. The results showed that TV viewer's family-related values and socio-economic characteristics influenced the family-related image reception behavior. Especially viewers' values about child was the most significant variable affecting TV viewers' receptions of family-related images reflected in soap operas.
