Video Playback Refresh Rate Switching for Power and Smoothness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face processor overload and high power consumption due to fixed high refresh rates during video playback, as the required refresh rate is often lower, leading to inefficiency.
Innovation Solution
A dynamic refresh rate setting method that adjusts the refresh rate based on whether bullet screen drawing is performed in a preset duration, switching between different refresh rates to match the video playing scenario.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed high refresh rate is used to ensure smooth picture display, then picture fluency is improved, but processor overload and power consumption increase
Solution Approach 1:
The refresh rate is changed from a fixed value to a dynamically adjustable parameter. The system automatically switches between different refresh rates (first refresh rate for video playback, second refresh rate for bullet screen display) based on the current display scenario, thereby optimizing power consumption while maintaining picture fluency when needed.
Solution Approach 2:
The refresh rate parameter is adjusted according to different display scenarios. When video playback is detected, the system sets the refresh rate to a lower first value to save power. When bullet screen drawing is detected, the system switches to a higher second refresh rate to ensure smooth display of interactive elements.
2Reliability
If a fixed high refresh rate is used to ensure smooth picture display, then picture fluency is improved, but processor overload occurs
Solution Approach 1:
The system dynamically adjusts the refresh rate based on the current display scenario rather than maintaining a fixed high refresh rate. This reduces unnecessary processor workload during video playback while maintaining smooth display performance when bullet screens are active.
Solution Approach 2:
The system applies a lower refresh rate (first refresh rate) when only video playback is needed, using just the necessary processing power. When bullet screen drawing is detected, the system temporarily increases to a higher refresh rate (second refresh rate) to handle the additional display requirements.
3Use of energy by moving object
If refresh rate is reduced for power saving in video playback, then power consumption is reduced, but display smoothness may be affected
Solution Approach 1:
The system changes the refresh rate parameter based on the detected display scenario. During video playback, a lower first refresh rate is used to save power. When bullet screen drawing is detected, the system switches to a higher second refresh rate to maintain display smoothness for the interactive bullet screen elements.
Solution Approach 2:
The system continuously monitors the display scenario to detect whether bullet screen drawing is occurring. Based on this feedback, it automatically adjusts the refresh rate to maintain optimal display performance while minimizing power consumption when high refresh rates are not needed.
