현재 현장에 설치되어 운용되고 있는 대부분의 디지털사이니지는 독자적인 설계와 구현으로 개발되었기 때문에 다른 시스템과 연동이나 상호 운용하기에는 많은 어려움이 있다. 향후 웹 기반의 개방형 디지털사이니지가 주류를 이룰 것으로 예상됨에 따라, 다양한 서비스나 단말장치와 연동할 수 있는 상호 운용성을 갖춘 솔루션을 위한 기술 표준화 작업이 활발하게 진행될 것으로 예상된다. 최근 몇 년 전부터 ITU-T, POPAI, W3C 등을 중심으로 디지털사이니지 기술 표준화가 진행되고 있으며, 국내에서도 디지털사이니지 산업이 성장하면서 표준화에 대한 관심이 고조되고 있다. 이에 본고에서는 ITU-T, POPAI, W3C, 일본 등 해외에서 행해지고 있는 최근의 표준 활동과 TTA를 중심으로 한 국내의 표준 활동을 소개한다.
