Dynamic Frame Rate Control for Media Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiency in controlling media processing devices to manipulate content presentation, particularly in navigating through audio and video content using remote control devices, which often require multiple interactions and are limited by physical proximity.
Innovation Solution
A method and system that allow users to control media processing devices using a wireless remote control to scan content by varying the play frame rate based on input duration, enabling accelerated navigation through content by increasing the frame rate when specific thresholds are exceeded, allowing users to move a playhead position quickly between segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If users press and hold the forward button for an extended period, then the frame rate increases to enable faster scanning through content, but this consumes more energy and may cause unnecessary rapid scanning when not needed
Solution Approach 1:
The frame rate is made dynamic rather than static. The system automatically adjusts the frame rate based on the duration of the button press input signal. When the button is pressed briefly, a lower frame rate is used to conserve energy. When pressed for an extended period, the frame rate increases to enable faster content scanning. This dynamic adjustment resolves the contradiction by making the speed adaptive to actual user needs rather than permanently high.
Solution Approach 2:
The system changes the frame rate parameter in response to the input signal duration. By monitoring how long the forward button is held pressed, the system adjusts the frame rate parameter accordingly - maintaining a lower baseline frame rate for energy efficiency, and transitioning to a higher frame rate when the user indicates a need for rapid scanning through extended button pressing.
2Speed
If the frame rate is increased to scan content faster, then navigation speed through content improves, but the device complexity increases due to threshold sensing and dynamic rate adjustment mechanisms
Solution Approach 1:
The system implements feedback by monitoring the duration of the button press input signal and using this information to adjust the frame rate. The processor senses how long the forward button is held pressed and provides feedback by automatically adjusting the content scanning speed. This feedback loop enables intelligent speed adjustment without requiring complex user interfaces or multiple control modes.
Solution Approach 2:
The system performs self-service by automatically adjusting its own frame rate based on the input signal duration without requiring external intervention or complex control logic. The processor inherently monitors the button press duration and autonomously determines the appropriate frame rate, making the navigation speed adaptation transparent and simplifying the overall control architecture.
3Adaptability or versatility
If multiple content operations (play, stop, pause, forward, rewind) are enabled through the remote control, then the device versatility improves, but the ease of operation decreases due to the need for multiple interactions and precise button pressing
Solution Approach 1:
The forward button is designed with multi-functionality. By varying the duration of the button press, the same physical button performs multiple functions: brief presses provide frame-by-frame or segment-by-segment navigation, while extended presses enable rapid scanning through content at accelerated frame rates. This universal design reduces the number of physical buttons needed while maintaining operational versatility.
Solution Approach 2:
The button's function is made dynamic based on press duration. Rather than requiring separate buttons for different navigation speeds and modes, the system dynamically interprets the button press duration to determine the appropriate scanning speed. This dynamic interpretation simplifies the user interface while preserving full operational capability across different content navigation needs.

AI summary
A method of scanning content comprises receiving an input signal indicating that content being displayed is to be scanned, sensing a duration of the received input signal, and scanning the content at a rate based at least in part on the sensed duration of the received input.
