Abstract: A user device presents media to a user in the form of multiple content items, each comprising media components such as videos, text, and images. The user device uses user data and information about a set of content items accessed by the user to predict an order in which the user will access the content items. The user device requests, in the predicted order, media components associated with a number of content items to prepare the content items for presentation to the user. Responsive to detecting a transition between a presentation of a first content item and a presentation of a second content item, the user device may re-prioritize a predicted access order for the content items. The user device may additionally request media components to download according to quality levels. For example, a slow network connection may prompt a user device to use lower resolution video.
