Nonlinear dynamic prioritized content caching for segmented content

Abstract

Systems, methods, and computer-readable media are disclosed for providing a nonlinear, dynamic, and prioritized content caching scheme for segmented content during playback. Certain embodiments provide new techniques for optimally determining preferred content, prioritizing the preferred content for download and consumption, and, in systems where storage and memory systems are constrained, utilizing the same prioritization system for optimized garbage collection. Example methods may include determining a current playhead position associated with a video playback. Certain methods include determining a cache priorities for fragments based on the current playhead position and the positions of the fragments in the video playback. A first fragment may be the next fragment with respect to the linear playback, and a second fragment may follow the first fragment. Certain methods include determining that the second cache priority is higher than the first cache priority and providing the second fragment to a user device.
