Aspects of the disclosure provide an apparatus that includes an interface circuit, a processing circuit and a display device. The interface circuit is configured to receive media description information of media data. The media data includes a plurality of segment streams having different coverage in spatial domain for video content, the media description information is indicative of the different coverage in spatial domain of the plurality of segment streams. The processing circuit is configured to determine one or more segment streams based on a region of interests for image generation and the different coverage in spatial domain of the plurality of segment streams, select segments in the one or more segment streams, and cause the interface circuit to request and receive the selected segments. The display device is configured to display images generated based on the selected segments.
