Abstract (en)

[origin: WO9859288A1] A digital home entertainment system comprises one or more slave processors, e.g, DSPs, for processing specific tasks, and a master processor, e.g., a CPU, for control of the system. The slave processor is capable of rebooting the master processor if the master processor has stalled. This slave-controlled rebooting avoids manual cold rebooting of the system and is particularly advantageous in open-architecture multimedia systems with asynchronously cooperating components.
