國立台灣師範大學數位媒體中心 摘要 虛擬製作系統是-項新興的電視節目開發科技,自1990 年起虛擬製作系統逐漸朝向商業 化發展以來,這項具有即時處理與整合資訊呈現與傳送功能的技術,一直是電視節目製作者 所引頸企盼的,理論上它應該是獨領風騷且備受青睞;然而事實並不盡然,這項嶄新的藝術 與技術的創新,卻因為專業度與複雜度的增加,使其在發展和推廣上受到阻礙,僅能以一個 緩步成長的趨勢在產業界發展。本文旨在介紹虛擬製作系統技術內含與發展特性,並對國內 外以虛擬製作系統進行相關節目製作應用的現況進行比較分析,以供做為未來發展應用之參 考。 關鍵字:虛擬製作系統、攝影機追蹤、詮釋資料ABSTRACT
Virtual studio system is a new technology of TV industry. This technology has the function of real-time processing and information integration which TV producers are expecting since 1990. Theo-retically,it is unique and is supposed to be the most popular technology on TV production. However,
there are boundaries of developing virtual studio system because it requires more professional compe-tency and techniques in content production. This phenomenon causes difficulty in developing this new technology,thus it is still ina beginning infancy stage in video production. Thepu中oseof this paper is to analyze virtual studio system and its functions and features for future use reference.
