摘要 <p>A system (10) and method (50) for distributing digital information, including download information and activation or digital rights management information, to one or more branch devices. The method includes a root device receiving digital information from an information source, and transmitting the download information and the activation information associated with the download information to one or more branch devices. The branch device, upon receiving the activation information can activate, install or execute the download information. The download information and/or the activation information can be conditionally distributed, e.g., based on a time-based, location-based or authentication-based condition or event. The method also may include extracting the distributed information, e.g., upon the completion of the condition or event. The root device and/or the branch device includes a controller configured to transmit and/or receive the digital information, via a transceiver, and configured to use the activation information to install or execute the download information.</p>
