Abstract
There is disclosed a system and method of predicting a location of a user's viewport using location information of a sound source in 360 virtual reality (VR) content. According to the present invention, the spatial representation description (SRD) and the sound source localization information (SLI) of the audio MPD are transmitted with the video MPD being extended, the SRD of the sound source is used to derive the location of the sound source, and the weights of the respective items of the region of interest (ROI), the sound source localization information (SLI), the current viewport, and the pole are allocated differentially according to the bandwidth condition and then multiplied by the reference bitrate to determine the segment bitrate to be provided next, thereby improving the accuracy of predicting the location of the user's viewport and ensuring the quality of experience (QoE) for regeneration speed and regeneration quality.
