Abstract: In an on-demand radio broadcast system (600) in which the receivers (602) have the capability to store received programs, a communications channel (300) is divided into a plurality of time segments (302). Each time segment (302) is partitioned into a high priority program timeslice (304) and a low priority program timeslice (306). High priority programs (336) are broadcast in each high priority program timeslice (304). The remaining programs are broadcast during a plurality of low priority program timeslices (306). This overcomes a problem of the receivers (602) being out of contact and not having current versions of the high priority programs (336).

Abstract translation: 在接收机（602）具有存储接收到的节目的能力的按需无线电广播系统（600）中，通信信道（300）被划分为多个时间段（302）。 每个时间段（302）被划分为高优先级程序时间片（304）和低优先级节目时片（306）。 每个高优先级节目时间片（304）广播高优先级节目（336）。 剩余的节目在多个低优先级节目时间片段（306）期间被广播。 这克服了接收器（602）不接触并且没有高优先级程序的当前版本（336）的问题。
