Abstract: Multiple copies of a software or operating parameter change are broadcast using a wireless signal to a mobile electronic device. Broadcasting multiple copies increases the probability that the mobile electronic device will receive the change without error. The number of copies broadcast is a function of the expected probability that the device will receive one copy without error and a desired probability that the device will receive the change without error.

Abstract: Broadcast programs, e.g., for an audio information program, are divided into one or more segments and are broadcast to a receiver in packet format. The receiver captures the transmitted packets and reassembles the segments and the program for storage and subsequent output to the user. Segment quality of service is evaluated prior to output by ensuring that a minimum percent of packets per segment are usable, and by ensuring that no more than a maximum number of consecutive packets in the segment are unusable. Program quality of service is evaluated by ensuring that a minimum percent of segments per program are usable, and by determining if the first and/or last segment is usable. Different quality of service parameters are specified for particular programs. New quality of service parameters for particular programs are transmitted to the receiver.

Abstract: In a local storage and playback broadcast system, multiple copies of one or more processing parameters used in individual receivers for the local storage and playback are broadcast. In some embodiments each processing parameter is associated with each packet in the program so that a copy of each parameter is broadcast with each packet. In some embodiments the program is divided into segments, each segment having a header, and a copy of the parameter is broadcast in each segment header.

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