Patent ID: 10965968

Abstract:
The present invention relates to a system for providing a stereoscopic 3D 360-degree virtual reality (VR) service based on a hybrid network. According to a detailed embodiment of the present invention, standardizing and multiplexing based on an ATSC 3.0 protocol for a base layer stream, an enhancement layer stream, and a stereoscopic stream which are derived from a high resolution left eye image and a high resolution right eye image which are captured by 360-degree cameras may be performed by performing MPD signaling, and thus realistic media such as HD and UHD resolution 360-degree VR broadcast services, stereoscopic 3D 360-degree VR services, etc. may be provided. In addition, system complexity may be reduced by deriving a base layer stream, an enhancement layer stream, and a stereoscopic stream by using one encoder, and thus compression efficiency may be improved.
