Abstract: The present disclosure provides a system for providing an image-segmentation based streaming service. The system includes a communication circuit configured to establish a communication channel with a streaming server, a storage configured to store data provided by the streaming server, a display configured to output an image, a processor functionally connected to the communication circuit, the storage, and the display. The processor can detect a region-of-interest (ROI) of an output image associated with a media presentation description (MPD) provided by the streaming server and transmit the ROI information to the streaming server. The processor can also receive image segments of a first resolution corresponding to the ROI information and a full image of a second resolution from the streaming server. The processor can also synthesize the image segments of the first resolution and the full image of the second resolution to output a synthesized reconstruction image through the display.

Abstract: An electronic device and a method for a tiled video multi-channel playback are disclosed. The electronic device includes a device communication unit and a device controller. The device communication unit establishes a communication channel with a streaming server. The device controller can detect a region of interest (ROI) of an image related to a media presentation description (MPD) tile provided by the streaming server, transmit ROI information to the streaming server and receive tiles of a tiled video having a first resolution and corresponding to the ROI information, a full video having a second resolution lower than the first resolution, and a plurality of 2D videos from the streaming server. The device controller can also generate a 360-degree VR video by synthesizing the video tiles and the full video, and control a simultaneous playback of the generated 360-degree VR video and the plurality of 2D videos.
