방송예술 및 콘텐츠 제작 역량을 교육시키는 방송예술특성화 대학으로서 C3(Creativity, Convergence, Contents) 방송예술 창의융합교육 모델인 융합수업을 개설하고 전체 학과에서 신청한 학생들을 대상으로 교육을 진행하였다. 융합수업은 전공이 다른 학생들이 희망하는 콘텐츠 제작과정을 수강하고, 방송사와 산업체에서 실무경험이 풍부한 교수와 전문가들이 직접 콘텐츠 제작을 지도함으로써 고품질의 수준 높은 콘텐츠 제작 교육을 경험할 수 있는 수업이다. 즉, 재학 중 학교수업을 통해 미리 현장 경험을 쌓음으로써 취업 즉시 콘텐츠 제작 역량을 발휘할 수 있는 자신감 함양과 제작현장에 기여할 수 있는 융합형 인재양성 교육프로그램인 것이다. 본 연구에서는 대학이 보유하고 있는 방송용 버츄얼 스튜디오를 활용한 가상 세트 영상 제작 교육 『영화담』을 제작하는 융합수업과 드론 항공촬영을 활용한 제작교육 『드론 탐사대』 융합수업을 실시하여 첨단 기술을 활용한 콘텐츠 협업 제작의 효과와 학생들의 만족도를 분석하였다.

In this paper, we presents visual effect(water, fire, smoke) simulation and interaction system for TV virtual studio. TV virtual studio seamlessly synthesizes CG background and a live performer standing on a TV green studio. Previous virtual studios focus on the registration of CG background and a performer in real world. In contrast to the previous systems, we can afford to make new types of TV scenes more easily by simulating interactive visual effects according to a performer. This requires the extraction of the performer motion to be transformed 3D vector field and simulate fluids by applying the vector field to Navier Stokes equation. To add realism to water VFX simulation and interaction, we also simulate the dynamic behavior of splashing fluids on the water surface. To provide real-time recording of TV programs, real-time VFX simulation and interaction is presented through a GPU programming. Experimental results show this system can be used practically for realizing water, fire, smoke VFX simulation and the dynamic behavior simulation of fish flocks inside ocean.

With the increase in interest in health in the society, a variety of fusion studies have been conducted by ICT to sports. This study develops a smart bicycle that is run only when a rider maintains balance, and proposes an interface of studio space where the smart bicycle can be experienced. The studio consists of interactive smart bike, a geodesic dome for immersion of content for a single person, and virtual reality content that is implemented to enjoy various sceneries in real space. This study contributes to attempts of design and production of studio that is optimized to interactive space of smart bike for single person. This studio has a scalable interface, which can be applicable to various other interactive contents for sportainmnet.

Chromakey method is one of key technologies for realizing virtual studio, and the blue portions of a captured image in virtual studio, are replaced with a computer generated or real image. The replaced image must be changed according to the camera parameter of studio for natural merging with the non-blue portions of a captured image. This paper proposes a novel method to extract camera parameters using the recognition of pentagonal patterns that are painted on a blue screen. We extract corresponding points between a blue screen. We extract corresponding points between a blue screen and a captured image using the projective invariant features of a pentagon. Then, calculate camera parameters using corresponding points by the modification of Tsai's method. Experimental results indicate that the proposed method is more accurate compared to conventional method and can process about twelve frames of video per a second in Pentium-MMX processor with CPU clock of 166MHz.

In order to produce an image that lends realism to audience in the virtual studio system. it is important to synchronize precisely between foreground objects and background image provided by computer graphics. In this paper, we propose a method of camera parameter extraction for the synchronization by tracking the pose of TV camera. We derive an equation for extracting camera parameters from inverse perspective equations for tracking the pose of the camera and 3-D transformation between base coordinates and estimated coordinates. We show the validity of the proposed method in terms of the accuracy ratio between the parameters computed from the equation and the real parameters that applied to a TV camera.
