Abstract

Recently, due to the development of network environment, the internet market has been expanding, so it is necessary to standardize the data format and API to exchange information among objects. Therefore, MPEG (Moving Picture Expert Group), an international standardization organization, is establishing the MPEG-IoMT (ISO/IEC 23093) project to standardize the Internet of Things. MPEG-IoMT establishes Core Experiment (CE) and discusses overall data exchange such as data exchange procedure, markup language and communication method. In this paper, core experiments 1, 2, 4, and 5 of the core experiments of MPEG-IoMT will be discussed. The performance information of the sensor, the sensor data, the performance information of the driver, and the exchange procedure of the control command are explained and the exchange of the media additional data is discussed. We compare the markup language and communication method through experiment.

최근 네트워크 환경의 발달로 인해 사물인터넷 시장이 확대되고 있어 사물 간의 원활한 정보 교환을 위한 데이터 포맷 및 API의 표준화가 필요하다. 이에 국제 표준화 기구인 MPEG(Moving Picture Expert Group)에서는 MPEG-IoMT(ISO/IEC 23093) 프로젝트를 신설해 사물인터넷 관련 표준화를 진행 중이다. MPEG-IoMT는 핵심실험(Core Experiment:CE)을 수립해 데이터 교환 절차, 마크업 언어, 통신 방식 등 전반적인 데이터 교환에 대한 논의를 하고 있다. 본 논문에서는 MPEG-IoMT의 핵심실험 중 핵심실험 1 MPEG-V 센서에 기반한 센서 API 설계, 핵심실험 2 MPEG-V 감각효과에 기반한 구동기 API 설계, 핵심실험 4 IoMT 데이터 표현을 위한 MPEG-21 디지털 아이템, 핵심실험 5 JSON과 RESTful API의 분석에 관해 살펴본다. 센서의 성능 정보와 센서데이터, 구동기의 성능 정보, 제어 명령의 교환 절차를 설명하고 미디어의 부가 데이터의 교환에 대해 논의한다. 또한 마크업 언어와 통신방식을 실험을 통해 비교한다.
