N2 - With the growing popularity of digital broadcasting, viewers the have chance to watch various programs. However, they may have trouble choosing just one among many programs. To solve this problem, various studies about EPG and Personalized EPG have been performed. In this study, we reviewed previous studies about EPG, Personalized EPG and the results of recommendation evaluations, and evaluated PEPG system's recommendation, which was implemented as working prototype. We collected preference information about categorys and channels with 30 subjects and executed evaluation through e-mail. Recall and Precision were calculated by analyzing recommended programs from an E-mail questionnaire, and an evaluation of subjective satisfaction was conducted. As a result, we determined how much the result of an evaluation reflects viewer satisfaction by comparing the variation of subjects' satisfaction and the variation of objective evaluation criteria.
