Abstract

Due to the development of the digital technology, the territories of broadcasting and telecommunications are being converged and there have been the efforts to eliminate the spatial and/or temporal restrictions in utilizing the services (usually implemented as applications) via various devices (e.g. smart-phone, smart TV, pad-computer, etc). In the circumstances, Web is coming to the fore as a common running platform of the services and the digital broadcasting receivers are pressed to run Web applications as well as Java applications, which are the standard of data service of the digital broadcasting. The paper introduces a platform for running HTML5-based Web applications, which is equipped with a Web kernel (an engine for running HTML5 Web applications), a Web desktop (the facilities (with an UI similar to Window OS) for managing Web applications), and SDK (a set of API's for Web application developers).

디지털기술의 발전으로 방송과 통신 영역 간에 융합이 이루어지면서 소비자의 다양한 디바이스를 통한 서비스(애플리케이션) 이용에 공간적, 시간적 제약을 제거하는 노력이 진행되고 있다. 특히 애플리케이션의 공통 실행 플랫폼으로 웹 (Web)의 중요성이 대두되면서 N-스크린 개념에 중요한 위치를 차지하고 있는 디지털방송 단말도 기존 데이터 서비스의 표준으로 삼고 있던 자바 (Java) 애플리케이션뿐만 아니라 웹 애플리케이션을 실행할 수 있는 플랫폼으로 발전하도록 요구되고 있다. 본 논문에서 소개하는 디지털방송 단말의 웹 애플리케이션 실행 플랫폼은 HTML5를 기반의 웹 애플리케이션 실행 엔진인 웹 커널과 웹 애플리케이션의 관리를 위한 윈도우 운영체제의 바탕화면 관리자와 유사한 웹 데스크탑, 그리고 웹 애플리케이션 개발자를 위한 SDK를 제공한다. 특히, 웹과 TV 영역의 기술적 접목을 통해 HTML5 기반 웹 애플리케이션이 프로그램 편성정보와 같은 방송 부가정보와 디지털방송 단말의 자원을 자유롭게 활용할 수 있는 웹 애플리케이션 개발 프레임워크를 제공한다.
