Skip-Forward Playback Control With Overshoot Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skip-forward functionality in entertainment systems is cumbersome due to limited flexibility and user overestimation of time required to advance to desired locations, leading to prolonged interruptions and viewing of unwanted content.
Innovation Solution
Implementing a system that allows users to set a custom skip-forward time duration, compensating for expected overshoot by calculating a new location based on the specified duration and overshoot value, and resuming playback at a speed greater than normal to efficiently reach the desired location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed skip-forward time duration is used, then the operation is simple, but the accuracy of reaching the desired location is poor due to user overestimation
Solution Approach 1:
The system performs preliminary analysis of user skip-forward behavior patterns and pre-calculates compensation values. When a user initiates a skip-forward command, the system has already prepared the overshoot compensation logic, automatically adjusting the skip duration based on historical data without requiring real-time user input or complex calculations during the actual skip operation.
Solution Approach 2:
The system implements feedback by analyzing user behavior after skip-forward operations (such as subsequent rewind actions) to determine actual overshoot amounts. This feedback is used to refine and update compensation values for future skip-forward operations, continuously improving accuracy while maintaining simple user interaction.
2Measurement precision
If users input multiple commands to compensate for overshoot, then the accuracy of reaching desired location improves, but the interruption time increases
Solution Approach 1:
The system performs self-service by automatically detecting when playback needs adjustment after a skip-forward operation. It monitors playback position and user behavior patterns, then autonomously executes compensatory actions (such as automatic rewind or adjusted playback speed) without requiring the user to manually input additional commands, thus maintaining accuracy while minimizing interruption time.
Solution Approach 2:
The system prepares compensation strategies in advance by analyzing historical skip-forward data and predicting likely overshoot scenarios. When a skip command is issued, the system has pre-computed the optimal compensation action, allowing it to execute the correction seamlessly without requiring multiple user commands or prolonged interruptions.
3Ease of operation
If users view content they wish to skip due to overshoot, then the skip-forward operation is simple, but the viewing experience deteriorates
Solution Approach 1:
The system uses feedback from user behavior patterns (such as immediate rewind actions or pause commands following a skip) to identify when unwanted content has been viewed due to overshoot. This feedback triggers automatic compensation mechanisms that adjust future skip-forward durations to prevent recurrence of the same overshoot issue, eliminating unwanted content viewing while keeping the operation simple.
Solution Approach 2:
The system autonomously monitors playback to detect when users are forced to view unwanted content after a skip-forward operation. It automatically adjusts subsequent skip-forward parameters or executes corrective playback actions without requiring user intervention, thereby preventing unwanted content viewing while maintaining operational simplicity.

AI summary
In some aspects, control circuitry receives and stores a user-specified time duration to associate with a skip-forward command. When the user later issues a skip-forward command to advance playback of a media asset to a desired location, the control circuitry retrieves the stored time duration, and determines an expected overshoot value associated with the skip-forward command. The control circuitry then compensates for the expected overshoot by calculating a new location in the media asset based on both the retrieved time duration and expected overshoot value. Upon advancing to the new location, the media asset is played back in a fast-forward mode, e.g., at a speed higher than normal speed.
