Computer Motion Picture Mode Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems face challenges in minimizing power consumption during multimedia usage, such as watching movies, as existing power management technologies do not effectively reduce power usage to extend battery life in portable devices.
Innovation Solution
A computer system and method that enters a 'motion picture mode' by supplying power only to necessary devices like RAM, graphic processing units, audio outputting units, and control units, while reducing CPU and bus clock speeds, to minimize power consumption during prolonged multimedia playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is supplied to all devices in the computer system, then all functions can be performed normally, but power consumption increases
Solution Approach 1:
The patent segments the computer system into essential devices (RAM, graphic processing unit, audio outputting unit, control unit) and non-essential devices. During motion picture mode, power is selectively supplied only to essential devices while non-essential devices are turned off, thereby reducing overall power consumption while maintaining core functionality for playing motion pictures.
2Use of energy by moving object
If clock speed of CPU and bus is reduced, then power consumption decreases, but processing speed decreases
Solution Approach 1:
The patent dynamically adjusts the clock speed of the CPU and bus based on the operating mode. During motion picture mode, the clock speed is reduced to minimize power consumption since the system is optimized for playback rather than high-performance computing. When exiting motion picture mode, the clock speed returns to normal levels to restore full processing capability.
3Use of energy by moving object
If power is supplied only to necessary devices, then power consumption is minimized, but system complexity increases
Solution Approach 1:
The patent changes the power supply parameters by introducing a motion picture mode that modifies the power distribution state of various devices. The control unit adjusts power supply parameters (on/off states of devices, clock speeds) to optimize power consumption during motion picture playback, thereby managing system complexity through parameter optimization rather than structural changes.

AI summary
The present invention relates to a computer providing a motion picture mode including at least one storage unit configured to store system state information when the computer enters the motion picture mode and to store motion picture data, the storage unit including a random access memory (RAM) and a hard disk drive (HDD), a graphic processing unit configured to process image data and to display processed data on a screen, an audio outputting unit configured to process and output audio signals, and a control unit configured to control modules included in the computer and a system mode of the computer. The control unit is configured to determine whether conditions for entering the motion picture mode have been satisfied, and to change the system mode to the motion picture mode if the conditions for the motion picture mode are satisfied.
