Abstract: An Internet of Things (IoT) device is deployed with embedded software that may comprise multiple components. After deployment, updated versions of one or more components of the embedded software may become available. The IoT device maintains a manifest of the installed components. Periodically, the IoT device requests an updated copy of the manifest from an upgrade server. The installed manifest and the updated manifest are compared to determine if updated versions of any components are available. If so, the IoT device requests only the components to be updated. Prior to beginning the copying of the upgraded components, an upgrade flag is set. The IoT device then begins copying the received components into memory, replaces the manifest with the updated manifest, and clears the upgrade flag.

Abstract: A wireless receiver, in the form of a mobile telephone, includes a DAB receiver and a GSM/GPRS transceiver which enables bi-directional point-to-point data communications via a service provider. The DAB receiver is arranged to receive media data from an over-the-air broadcast channel, the media data primarily representing television and radio streams. In order that the streams can be decoded and decrypted by media playing software on the wireless receiver, a provisioning operation is employed to provide NSC header files and DRM licenses to users in response to them making content requests. The header files and licenses are sent over a separate data channel and in advance of the broadcast content.

Abstract: A wireless receiver (17), in the form of a mobile telephone, comprises a DAB receiver (31) and a GSM/GPRS transceiver (29) which enables bi-directional point-to-point data communications via a service provider (55). The DAB receiver (31) is arranged to receive media data from an over-the-air broadcast channel, the media data primarily representing television and radio streams. In order that the streams can be decoded and decrypted by media playing software (47) on the wireless receiver (17), a provisioning operation is employed to provide NSC header files and DRM licences to users in response to them making content requests. The header files and licenses are sent over a separate data channel and in advance of the broadcast content.
