DEVICE STORAGE OPTIMIZATION

原文（中国語）

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for optimizing storage on a user device where an application for streaming video content is executed. Lifespans of videos stored on a disk of a device or in a memory of the device can be determined based on computed repeat probability rates for the videos. Weighted ratios for each of the videos can be computed as a ratio between a lifespan of the respective video and a duration of time for storage of the video on a) the disk or b) in memory. One or more video can be determined to be removed from the videos based on applying a deletion ratio over a sorted list of the videos. The sorted list is generated based on the computed weighted ratios.
