Pre-caching video content to devices using LTE broadcast
Aspects of the subject disclosure may include, for example, a device including a processing system that receives items of media content; delivers the items over a network according to a schedule determined by a content delivery scheduling system; detects a level of broadcast network capacity utilization; and periodically generates and transmits to the scheduling system a forecast of network capacity utilization.

A resource for delivering the items of media content is dynamically assigned to the processing system by the scheduling system in accordance with a current forecast. The items of media content comprise a queue accessible to the content delivery scheduling system; the queue is maintained by the scheduling system and is uniquely assigned to the processing system. Other embodiments are disclosed.
