Abstract

The disclosed idea revolves around the usage of DAB (Digital Audio Broadcast) data channels for transmitting software packages and updates of software packages to a large number of clients in a cost effective, efficient, and timely fashion. Currently, delivering software packages to devices or installing software update on devices is a costly and time-consuming business. Either the software needs to be downloaded over dial-up lines or Internet connections or else supplied and mailed on physical media such as floppy disk, tapes, CD-ROMs, or DVD-ROM or other storage media. Both ways of distributing the software or the software updates suffer from being costly and slow. In addition, due to network congestion or delays in delivery by mail delivery of the software or software upgrade cannot be accurately timed and, thus, not be relied on to be available at a given point in time. The technique described here uses the datacasting features of DAB to deliver software and software upgrades to large numbers of clients at the same time, at low cost, without incurring delivery delays. The technique makes use of the Digital Audio Broadcasting system but is by no means limited to DAB and can be applied to other broadcasting system offering datacasting capabilities.
