Emerging three-dimensional television (3DTV) as a new IT product shows a possibility that television is not for just watching broadcasting, but an attractive tool for applying it to our real life. Three dimensional television is generally more effective and attractive than two-dimensional television (2DTV). But it still needs continuous technological improvement to solve its inherent limitations until many customers decide to purchase 3DTVs without hesitation. Innovative products like 3DTV encounter a quality problem leading purchase decision by customers. Quality is regarded as one of the most important factors affecting customers to adopt and use the product. Furthermore, measuring quality effectively is considerable for the 3DTV research. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for evaluating 3DTVs in a view of quality. We describe quality criteria affecting the 3DTV selection through a literature survey and develope an analytical method for measuring quality. We classify the quality of 3DTV into four types and suggest a concept of the quality ratio as a measurement criteria instead of the quality gap. Though a numerical example, we show how priorities of 3DTV with versatile manufacturers is computed.

3차원 텔레비전(3DTV)는 이차원 텔레비전(2DTV)을 대체할 새로운 혁신기술로 여러 제조사로부터 다양한 모델이 출시되고 있다. 3DTV는 매력적 요소에도 불구하고 내재된 문제점, 제조사별 기술적 차이점 때문에 소비자들은 제품선정을 위한 복잡한 의사결정 문제에 직면한다. 일반적으로 구매자들은 제품 사양을 비교하는 방식을 사용하지만 3DTV 특성상 실제 체험한 후 선택하는 것이 바람직하다. 본 연구는 소비자들이 3DTV 구매 의사결정을 지원하기 위한 일련의 방법론을 제안한다. 제품선정 기준을 도출하고 계층적분석과정(AHP) 모델을 구축한다. 이용자 테스트 방법을 제안하며 수치적 예제를 통해 제품의 우선순위가 결정되는 과정을 보인다.
