Abstract
In one embodiment, a method for protecting video content is implemented on at least one computing device and includes: receiving the video content as encrypted video data on the at least one computing device, determining a viewport within the encrypted video data, where the viewport represents a subset of a larger amount of video that is presentable at a specific point in time in the video content, decrypting at least a portion of the encrypted video data corresponding to the viewport, where at least a remaining portion of the video that is time synchronized with the viewport remains encrypted, rendering viewport video from the viewport, and playing the viewport video.
