<p><P>PROBLEM TO BE SOLVED: To provide a system and a method in which an auxiliary computing device wakes an associated main computer system to obtain data as needed, on-demand and/or in anticipation of demand. <P>SOLUTION: A wakeup operation is ordinarily temporary to fetch data, whereby only a small amount of power is consumed by the main computer system. A control channel between the auxiliary device and the main computer system is used to signal a wakeup. A main data channel is used to obtain the data, whereby the auxiliary device has access to a larger amount of data than it can cache. The components of the main computer system may be leveraged, such as to use the main computer system's digital copyrights management mechanisms. Additional data may be requested by the auxiliary device while the main computer system is powered up, e.g., to request buffering of media, or a synchronization of calendar data, e-mail data, and so on. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
