LED Wall 기반 미디어콘텐츠 저작기술 유형 및 특성연구

Abstract

(Background and Purpose) Since 2019, the global outbreak of Covid-19, along with its variants and mutant viruses, has caused chaos and a tumultuous pandemic, impacting most industries worldwide. With the end of Covid-19, technological advancements and transformations have accelerated in various industries. Among these, the media content market that utilizes LED walls is notable, and its market size is predicted to grow globally each year. Despite the significant growth and future value of technology based on LED walls for media content production, academic research on the status and characteristics of this field is lacking. Therefore, this study aims to investigate and analyze the types and characteristics of technologies used in media content production based on LED walls, providing practical insights and foundational data for future academic development. (Method) The research methodology involved confirming the theoretical definitions of technology types related to LED-wall-based content production, followed by studying the characteristics based on representative domestic and international cases and the types utilized in media content. The research was limited to media content within various fields that utilize LED walls, allowing for a clear distinction of the scope. (Results) The analysis of the characteristics of technology types based on LED walls and their utilization in media content, focusing on representative cases, revealed common spatial characteristics of LED wall-based audiovisual (AV) and in-camera VFX (ICVFX) technologies, as well as their technical features utilizing camera tracking equipment. However, it was observed that while the LED wall-based AV creates an infinitely expandable space centered around a limited LED wall, the ICVFX differs by using a limited LED wall for shooting. Additionally, in terms of shooting techniques, LED wall-based AV primarily focuses on shooting media content (background), whereas ICVFX exhibits the characteristic of shooting with a focus on individuals. The type of LED wall affected the lighting effects between flat and curved LED. The curved LED exhibited an even distribution of light, whereas the corners of the flat LED were darker. Furthermore, from a cost perspective, it was confirmed that curved LED incur higher costs than flat LED because of the larger number of LEDs used. (Conclusions) Through an analysis of case studies, the characteristics of various technology types based on LED walls utilized in media content production were identified, including their similarities, distinctions, and limitations. It is expected that this analysis will serve as foundational data suitable for practical use by industry professionals utilizing LED wall-based media content production techniques and researchers in the academic field.
