초록

동영상이나 음성을 포함하는 멀티미디어 정보는 사람들이 쉽게 이해 가능하다는 점에서 활용도가 높다. 이러한 이유로 멀티미디어 정보를 저장한 IoT 장치가 스마트폰과 연동하여 정보를 전달하는 응용들이 연구되었다. 문제는 동영상이나 이미지 등으로 인해 정보의 크기가 IoT장치의 용량보다 커질 수 있다는 것이다. 본 논문에서는 IoT 장치처럼 저장용량에 한계가 있는 경우, 저장 용량의 한계를 고려한 멀티미디어 콘텐츠 설계 기법을 연구하였다. 동영상이 문자보다 정보 이해도가 높은 반면 용량은 크다는 점을 고려하여 정보 이해도와 용량 간의 해법을 구하는 것이다. 정적미디어와 동적미디어의 크기를 변수로 하고 선형 계획법에 의거하여 해를 풀이한다. 사례 연구를 통하여 본 논문의 설계기법이 유용함을 보였다.

Multimedia information, including video and voice, is highly utilized in that it is easily understood by people. For this reason, applications have been studied which store multimedia information in IoT devices and transmit information in conjunction with smartphones. The problem is that the size of information can be larger than the capacity of IoT devices due to video and image. In this paper, the multimedia content design technique, which takes into account the limitations of storage capacity, was studied when there is a limit of storage capacity. Considering that the video has a higher understanding of information than text, while the capacity is larger, the solution between information comprehension and capacity is sought. The size of static and dynamic media is a variable and the harm is solved in accordance with the linear planning method. Case studies have shown that the design techniques of this paper are useful.
