Remote Media Scanning Control Using Press-Duration Speed Shifts
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, as existing systems require multiple interactions and lack efficient scanning capabilities.
Innovation Solution
A method and system that allow users to control media processing devices using a remote control to scan content by sensing input duration and adjusting the play frame rate, enabling accelerated movement of a playhead within the content, allowing users to quickly reach desired viewing points through forward and backward scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users interact with the remote control device multiple times to navigate content, then control precision is improved, but user interaction time increases
Solution Approach 1:
The patent applies dynamics by making the content scanning rate variable rather than fixed. The scanning rate automatically adjusts based on the duration of the user's button press: shorter presses result in lower scanning rates while longer presses trigger higher scanning rates. This dynamic adjustment allows the system to adapt to different user needs in real-time, providing precise control when needed and rapid navigation when desired, thereby resolving the contradiction between control precision and interaction time.
Solution Approach 2:
The patent changes the scanning rate parameter in response to input duration. When the user presses the navigation button, the system senses the duration and modifies the scanning rate parameter accordingly - increasing it for longer presses and maintaining lower rates for shorter presses. This parameter change enables the single button press to achieve what previously required multiple interactions, reducing user interaction time while maintaining precise control capability.
2Productivity
If the content scanning rate is increased to enable faster navigation, then productivity is improved, but control precision deteriorates
Solution Approach 1:
The system dynamically adjusts the scanning rate based on the duration of the user's button press. When the user needs fast navigation, they press the button longer, triggering a higher scanning rate that quickly moves through content. When precision is needed, shorter presses result in lower scanning rates that allow finer control. This dynamic relationship between press duration and scanning rate resolves the contradiction by making both high speed and high precision accessible through different user actions.
Solution Approach 2:
The patent implements periodic action through the relationship between button press duration and scanning rate cycles. Longer presses initiate higher-rate periodic scanning cycles, while shorter presses initiate lower-rate cycles. The system continues scanning at the selected rate until the user releases the button, at which point the rate changes again. This periodic structure allows the user to control both speed and precision through the timing of their actions.

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.
