Cable TV Home Shopping is one of the popular distribution channels in modem society because of purchasing convenience and saving in shopping time. However, in spite of these advantages, there are some problems because of marketing strategies of many Cable TV shopping companies which stimulate impulse purchases. This study is aimed to find the relationship between buying experience and reaction to impulsive buying stimulus. This study can give a valuable insight in consumer education regarding impulsive purchase behavior in Cable TV home shopping. Study results can also give useful information on the direction of consumer campaign and consumer protection policies. The data was collected by using a questionnaire and the final 496 cases were analyzed by SPSS Win 10.0 program. The major finding were that: 1. Younger, more educated and unmarried consumers tend to response more to impulsive purchasing stimulus. 2. consumers with higher response to impulsive purchasing stimulus had more buying experience, higher shopping frequencies and spent more money in Cable TV home shopping than consumers with lower response. These study results showed that there are some relationship between impulse purchasing stimulus and buying experience in Cable TV home shopping. Therefore, Cable TV Home Shopping companies should provide correct information to the consumers, so they can make resonable decisions.

This paper examines the potential of Ultra-High Definition TV (UD-TV) broadcasting transmission systems beyond HD-TV over cable channel. Firstly, we analyze the trend of TOV(Threshold of Visibility) by extending the OpenCable (J.83 Annex B) system 256QAM which is the standard of Korean and American cable television transmission to 1024QAM, and realize that the OpenCable 1024QAM has nearly 30% higher data rate than 256QAM at the expense of impractically higher TOV (Threshold of Visibility). To achieve practical TOV, we control code rates of inner convolutional coder and replace turbo coder in forward error correction (FEC) part, thereby analyzing the best performance of the OpenCable systems having conventional FEC. In that result, it is necessary to modify conventional FEC of the OpenCable system to achieve under 31.5dB TOV. Moreover we study the potential of UD-TV transmission via two or more TV channels, so called channel bonding, through the Shannon capacity in 6MHz channel and the relationship with next generation A/V codec technologies.

This research aimed to examine consumer's expectancy disconformation related to purchase satisfaction/dissatisfaction and post-purchase behavior in cable TV home shopping. A total of 700 questionnaires were randomly sent to cable TV home shoppers and 172 copies were used in final analysis. Frequency analysis. correlation analysis, analysis of variance, regression analysis, path analysis, and multinominal logit were used. The expectancy discoformation on \"fitting\" and \"how well the clothes suits oneself\" were significantly related to the complaint behavior of return and refund. TV home shoppers tended to express their complaints by requesting the home shopping company or the manufacture company for a compensation rather than express privately such as warning friends, stop buying and boycotting the item. The significant variables that would influence consumers to seek refund rather than exchange were purchase satisfaction, request of compensation to the company, overall expectancy disconformation and expectancy disconformation on decoration and details and suiting oneself.

The purpose of this study is to examine the effects of situational involvement on impulse buying of clothing products in cable TV home shopping. Data were obtained from 235 women aged between 20 and 50 living in Seoul metropolitan area who have bought apparel products on impulse through cable TV. The data were analyzed using factor analysis, cluster analysis, MANOVA, and Chi-square analysis. By factor analysis, two factors of situational involvement factors were identified: Emotional Involvement and Cognitive Involvement. Based on situational involvement, consumers were classified into four groups; High Involvement, Low Involvement, Cognitive Involvement, and Emotional Involvement groups. These groups showed different decision making styles. The situational involvement groups were also different in terms of demographic characteristics, purchase behaviors, types of impulse purchase products, and responses to marketing stimuli. The findings of this study provide useful information for retails of Cable TV home shopping. Retailers may need to make useful marketing efforts for each types of situational involvement.

In this study, the impact on the number of cable TV subscribers as well as the profit of cable TV has been examined, and the impact on enlarging the digital broadcast viewing rights of cable TV subscribers and viewers' welfare has also been examined. We investigated the trends in the number of analog and 8VSB subscribers and revenue of cable TV operators by region and analyzed based on changes in the number of channels provided by each operator. The results show that analog subscribers and digital subscribers are delaying their departure through 8VSB conversion, and VOD subscription fees and home shopping transmission fees have a significant impact on operating profit. Subscribers, as they switched over to 8VSB, have become able to view channels of various genres with clear picture quality for a same subscription fee, and the program providers could offer programs to more customers. The government's deregulation policy due to the changes in broadcasting environment led to the facilitation of digital conversion of Pay-TV and improvement of viewers' welfare.

Since the 1960s in Korea, major broadcasting channels broadcasted farm television programs, however, airing of these programs were reduced in the 1990s. This was due to the declining number of farmers, and the low popularity rating of farm television programs. To cope with the situation, agriculture businessmen, farmers, and the officials concerned tried to acquire the independent farming television channel in cable television and satellite television, In 1998, one cable television channel started broadcasting, while another channel in satellite television began its broadcasting in 2001. One of the major concerns of the people in the broadcasting was actualization of the public interests in the new media multi-channel age. Recognizing this point, the study explored a few areas of concern such as conceptualizations of the public interest of the people in the digital age, examination of the surroundings of program production and marketing, and survey the media use behavior of target audience - rural residents; In the concept of the public interest, there are two points of view; market focused and democratic principle oriented. As the digitalization of broadcast advances and the logic of economics prevails, it is difficult to offer the public broadcasting service to farmers, however, democratic principles should be more emphasized. The rural resident prefer major terrestrial television channel to cable television and satellite television channel, and in media use behavior, the medium of major terrestrial television would be more useful for farm broadcasting.

As cable TV networks have a media feature that is a broadband wire network, they can provide not only TV broadcasting services but also communication services. Accordingly, the cable TV network is mentioned as the optimal network for convergence of broadcasting and communication services. Recently, Available frequencies of the cable TV network have become insufficient as enhancement of video quality, increment of VoD service, and growth of high-speed internet service. This paper presents a new implementation method of switched digital video (SDV) technology that is introduced for obtaining additional frequency band. In the SDV system, only TV channels requested from viewer are sent and non-requested channels are dropped. The presented SDV uses a sharing method of TV broadcasting and communication service in a same frequency band. This method shows increase of spectrum efficient from switching of TV service channels without building a complex system.

Due to rapid convergence trends in the digital pay TV market, differentiation among the competing medias decreases and substitutability is increasing. The current study aims to explain the effect of service substitutability among competing media on the size of domestic digital pay TV subscribers. For the analysis, the Lotka-Volterra model, an ecological competitive diffusion model, was used to obtain the basic model for a simulation study. A simulation was performed by adjusting independent variables of substitutability to estimate the size of subscriber for particular media. The relationship between the digital cable TV and the IPTV is identified as a predator-prey relationship and the digital cable TV is found to be superior to the IPTV. The simulation results showed that the increase of convergence and substitutability result in the decrease of the entire media market. Especially, the IPTV is estimated to face the greatest loss in this context.
