    摘要： Methods and systems of processing content by a client are described wherein the method includes: receiving scene information defining two or more viewpoints in a scene, each of the two or more viewpoints being associated with an area in the scene and with a plurality of quality versions of video content, the video content defining one or more views in the scene associated with a viewpoint; receiving position information associated with a user of a playback device, the position information defining at least a user position and, optionally, a viewing direction of the user in the scene; if the user position is outside the areas associated with the two or more viewpoints, then selecting first content of a first quality associated with a first viewpoint and second content of a second quality associated with a second viewpoint in the scene based on the position information and the scene information; sending a request to a server system, the request comprising information about the first content of the first quality and the second content of the second quality and, optionally, the position and/or viewing direction of the user in the scene; and, receiving, in response to the request, video frames comprising the first and second content for generating synthesized content on the basis of the first and second content, wherein the synthesized content is associated with the position of the user in the scene; or, receiving video frames comprising synthesized content associated with the position of the user in the scene, wherein the synthesized content is synthesized based on the first and second content.

    摘要： Systems, methods, and non-transitory computer-readable media can determine at least one salient point of interest in a frame of a content item based at least in part on a saliency prediction model, the saliency prediction model being trained to identify salient points of interest that appear in content items; determine a barrel projection representation for the frame; and apply a view-based projection to the barrel projection representation for the frame, wherein the view-based projection enhances a quality in which a region corresponding to the at least one salient point of interest is presented.
