Abstract
The quantity of unused channels in a cellular wireless communications system is identified. From program content that is stored in a database, an amount of program content is accessed based on the identified quantity of unused channels. The accessed program content is formatted for broadcast on at least a portion of the unused channels, and the formatted content is then transferred to the cellular wireless communications system for broadcast to mobile receivers. In some embodiments a content transmission schedule is broadcast on one of the unused channels.
