Abstract: A system for providing an adaptive AR streaming service may comprise: a cloud AR server that stores an AR object composed of a plurality of progressive mesh chunks, and a meta file including property information of the AR object and the progressive mesh chunks; and a mobile augmented reality (AR) device that requests and receives the meta file from the cloud AR server, parses the meta file to identify a property of the AR object, and implements augmented reality.
