Dual OS Kernel Pre-loading for Fast Multimedia Booting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for booting computer multimedia systems from standby mode are slow and power-intensive, requiring a full boot process before transitioning to multimedia mode, which wastes time and energy.
Innovation Solution
A method that installs two operating systems and their kernels on a computer's hard disk, allowing the system to enter a standby mode after initial booting, and quickly switch to a multimedia mode upon detecting a predefined event signal, enabling fast booting and power-saving by loading the multimedia OS kernel and drivers directly into system memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the computer enters standby mode to save power, then power consumption is reduced, but booting time increases when transitioning to multimedia mode
Solution Approach 1:
The patent applies preliminary action by pre-loading the second operating system kernel into system memory during the first OS operation. This allows the kernel to be readily available when transitioning to multimedia mode, eliminating the need for a full boot process from disk and thus reducing booting time while maintaining power-saving standby capabilities
2Reliability
If the computer completes full booting process with all peripherals activated, then system readiness is improved, but power consumption increases
Solution Approach 1:
The patent segments the operating system into two parts: the first OS remains on disk for power-saving standby mode, while the second OS kernel is partially loaded into memory for quick activation. This segmentation allows the system to maintain readiness for multimedia operations without fully activating all peripherals, thus reducing power consumption while preserving essential system readiness
Solution Approach 2:
The system performs preliminary action by pre-loading essential kernel components of the second OS into memory during first OS operation. This prepares the system for rapid transition to multimedia mode without requiring a complete boot sequence, thereby maintaining system readiness while avoiding continuous high power consumption
3Adaptability or versatility
If dual operating systems are installed for different modes, then system versatility is improved, but device complexity increases
Solution Approach 1:
The patent divides the dual-OS system into functional segments: the first OS handles normal computer operations from disk, while only the kernel of the second OS is loaded into memory for multimedia mode. This segmentation reduces the active complexity compared to running both full OS instances, while maintaining the versatility to switch between normal and multimedia modes

AI summary
A method of fast booting for multimedia playing from a standby mode is provided, including installing at least a first operating system, a second operating system and the kernel of the second operating system in the hard disk of the computer. An event signal generating unit is connected to the computer. When the computer completes the booting process with the first operating system, a memory region for the kernel of the second operating system is established in the system memory, and the kernel of the second operating system kernel is loaded into the memory region. When the user shuts down the computer, the computer enters a standby mode. If the user operates the event signal generating unit when the computer is in the standby mode, the computer awakes and starts executing the second operating system kernel in the memory region and the computer enters the multimedia playing mode.
