Abstract

EBS has been producing numerous educational contents with traditional virtual studio production systems since the early 2000s and applied AR video production system in October 2020, twenty-years after. Although the basic concept of synthesizing graphic elements and actual image in real time by tracking camera movement and lens information is similar to the previous one but the newly applied AR video production system contains some of advanced technologies that are improved over the previous ones. Marker tracking technology that enables camera movement free and position tracking has been applied that can track the location stably, and the operating software has been applied with Unreal Engine, one of the representative graphic engines used in computer game production, therefore the system's rendering burden has been reduced, enabling high-quality and real-time graphic effects. This system is installed on a crane camera that is mainly used in a crane shot at the live broadcasting studio and applied for live broadcasting programs for children and some of the videos such as program introductions and quiz events that used to be expressed in 2D graphics were converted to 3D AR videos which has been enhanced. This paper covers the effect of introduction and application of the AR video production system on EBS content production and the future development direction and possibility.

2000년대 초부터 전통적인 가상 스튜디오 제작 시스템을 활용하여 수많은 교육 콘텐츠를 제작해 온 EBS는 약 20년만인 2020년 10월에 AR 영상 제작 시스템을 도입했다. 카메라의 움직임과 렌즈 정보를 트래킹하여 실시간으로 그래픽 요소와 실사를 합성한다는 기본 개념은 유사하지만, 새로 도입된 AR 영상 제작 시스템은 이전보다 개선된 몇 가지 최신 기술이 적용되었다. 좀 더 자유로운 카메라의 움직임을 가능하게 해주고 안정적으로 위치 트래킹을 할 수 있는 마커 추적 방식의 트래킹 기술이 적용되었고, 운영 소프트웨어는 컴퓨터 게임 제작에 활용되는 대표적인 그래픽 엔진 중 하나인 언리얼 엔진이 적용되어 시스템의 렌더링 부담은 줄어들면서 고품질의 실시간 그래픽 효과가 가능하게 되었다. 해당 시스템은 생방송 전용 스튜디오에서 부감 촬영을 담당하는 크레인 카메라에 설치되어 어린이 대상 생방송 프로그램에 주로 활용되고 있으며, 2D 그래픽으로 표현되던 코너 소개나 퀴즈 이벤트 등의 영상 중 일부가 3D AR 영상으로 전환되었다. 본 논문에서는 AR 영상 제작 시스템의 도입과 적용이 EBS의 콘텐츠 제작 측면에 있어서 어떤 변화를 가져왔는지와 향후 발전 방향과 가능성에 대해 알아본다.
