This paper presents a intuitive, simple and easy smart home TV remote control system using the hand gesture recognition. Hand candidate regions are detected by cascading policy of the part of human anatomy on the disparity map image, Exact hand region is extracted by the graph-cuts algorithm using the skin color information. Hand postures are represented by shape features which are extracted by a simple shape extraction method. We use the forward spotting accumulative HMMs for a smart home TV remote control system. Experimental results show that the proposed system has a good recognition rate of 97.33 % for TV remote control in real-time.

In this paper, we present an algorithm for efficient control of backlight LED in order to reduce the power consumption of LCD TV. In addition, a pragmatic implementation method is presented. In conventional local dimming control, backlight LEDs of LCD TV are divided into $M{\times}N$ blocks. And, the proper luminance for each block is computed according to input image and used for dimming control. But, LED light of each block is diffused and affects the neighboring blocks, so that luminance of each block becomes larger than that of intent. In the proposed algorithm, dimming control values are reduced by the amount of quantity affected by the neighboring blocks using light spread function, resulting in additional reduction of power consumption.

Among the diverse apartment brand TV Ads, KCC Switzen uses a unique advertising strategy. Unlike their competitors, KCC Switzen uses a strategy without fancy rhetoric such as luxury, premium or high-tech to enhance the value of their housing. In order to define the value of contemporary housing this paper analyses the socio-cultural messaging of KCC Switzen's television advertisements using Qualitative content analysis and Floch's Semiotic Square of Consumption Values method. As a result of this analysis, KCC Switzen's advertisements are shown to contain both intrinsic values of housing and cultural humanism by asking ablout the daily lives of real families and their relationships with neighbors. This directly contrasts with the standard advertisements that focus on the investment value of residential housing. The unique KCC Switzen advertising strategies are expected to change the paradigm of residential housing.

The purpose of this study is to analyze consumers attitude toward PPL (Product Placement) of fashion products on TV, with regarding PPL as a new-communication sphere of marketing. This study used a questionnaire method, and the results of the analysis are as follows. First, as for the information availability of PPL related to fashion products on TV, it was shown to be higher in order of trend, brand, color, practicability, price and material. Second, as a result of analyzing, through 11 items, the attitude on PPL experience of fashion products on TV, there were many positive responses as to 5 items (The commodity with PPL is the product of a renowned brand, The commodity with PPL is the expensive product, An image of the product with PPL becomes good, The product with PPL is suitable to the mood in a drama, I try to think whether the product with PPL matches with myself), and there were more negative responses as to 6 items (Because of desiring to know a brand of the product with PPL, I look for it, The product with PPL is practical, The product with PPL is same as the real situation, I will also buy the product with PPL, Because there are too many commodities with PPL, I become angry, In case of facing PPL, I change a channel). Third, it was shown that the purchase experience and purchase intention as to the product with PPL on TV, have a positive correlation with TV viewing time and with whether or not re-approval as to PPL of a specific company. Also, the purchase experience as to the product with PPL on TV was shown much in the group of viewing TV via internet and in the group of using the digital TV broadcasting. The purchase intention as to the product with PPL on TV was shown higher in the group of using much cable TV broadcasting and general TV broadcasting, while the group of viewing TV via internet had purchase experience, but the response of not having intention of repurchasing was the highest.

This paper proposes a stereo image insertion technique on DCT coefficients using the embedded method developed in the digital watermarking in due consideration of compatibility with conventional 2D system such JPEG, and MPEG. In conventional transmission method users with conventional digital TV cannot watch the transmitted 3D image sequence as 2D image, because of affectivity of conventional 3D image compression. To give an answer, in this paper, DCT coefficients are changed according to its disparity on YCbCr channels. Our method can insert stereo images into a conventional image compression method based on DCT.

Public Service Advertising(PSA) is the integrated marketing concept including strategy and technology in all its aspects that pursue the changes of community to seek an agreement of its members by the intentional and the target oriented way. PSA to the exclusion of commercial intention reflects the current social flow and subject since it is focused to the social issue. PSA plays an important role in creating the further cultural value, and also affects present cultural value to advertising message. In this aspect, this study is very valuable to design the plan for further effective management of advertisement and to analyze communication strategy of PSA. This study is to make dear the nature of PSA by the analysis of contents of visual image and linguistics' factors in actual produced and broadcasted TV advertising, called 'Protection of environment' In the results, PSA related the environment is working to linguistic-centered persuading message corresponding to visual factor, this intends to educate and instruct the consumers in 1980's. PSA, therefore, shows a non-description nature without story line and a hero(heroin) on it. In contrast, after 1990's, PSA was made up image-centered and maximized the effectiveness public campaign through the activating consumer's judgement and intervention. We are able to know that it contributes to considering and persuading the consumer to suggest the story format through the visual way to deliver the message. This study of relationship between visual image and linguistics is a common trend appeared in all media including today's advertising, and may be a remarkable result to present proper direction of PSA campaign.

The foodservice industry is applying new marketing strategies, and advertisements are the best way to convey their distinctive brand images. The foodservice companies have been choosing a type of advertising called Product Placement(PPL) because it is unconsciously shown more often than other types of advertisements while customers are watching a movie or TV drama. Therefore, the aims of this research were to investigate the influence of the customers' perception of PPL inserted into TV dramas on brand image and purchasing intention. Additionally, present study performed to identify the differences between Korean and Chinese customers. For the survey, the study used both offline and online sampling methods, and the analyzed data was from 150 Korean and 150 Chinese respondents. As results, the more respondents were positive and familiar about PPL, the higher the brand image and purchasing intention. Chinese consumers had positive perception of PPL, which positively influenced the brand image and purchasing intention while Korean consumers' ethical awareness about PPL had a negative influence. Therefore, the Korean foodservice industry needs to differentiate the strategies for the PPL marketing between the Korean and Chinese market.
