UCA 기술은 이종망과 다양한 단말로 구성되는 통방융합 환경에서 사용자가 언제 어디서나 원하는 방송 콘텐츠를 다양한 수준의 품질이 보장된 형태로 접근/소비할 수 있는 유비쿼터스 콘텐츠 서비스를 제공하기 위한 상호연동 가능한 멀티미디어 프레임워크 기술이다. UCA 기술은 OSMU, E2E QoS-enabled 콘텐츠 서비스, 개인 맞춤형 소비를 위한 서비스 기능 등을 제공하는 것으로, 향후 All-IP 기반의 통합 인프라로 진행될 것으로 전망되는 통방융합의 기반 기술로 통방융합 Info-Structure를 제공하기 위한 기술이라고 할 수 있다. 본 고에서는 UCA 기술의 전반적인 기술 개요 및 표준 기반의 주요 핵심기술을 소개하고 관련 기술개발 동향 및 전망을 살펴본다.
