Fast-Access Media Playback Near-Position Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media playback systems lack flexibility in adjusting fast-forward and rewind operation rates, often overshooting desired positions and failing to adapt to user interests, leading to inefficient navigation through media content.
Innovation Solution
A media guidance application monitors user interactions and maintains a viewing history to dynamically adjust playback rates, slowing down operations near previously viewed positions, allowing precise navigation and review of content segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If fast-forward or rewind operation is performed at high rate, then navigation speed through media content is improved, but precision in reaching desired playback position deteriorates
Solution Approach 1:
The playback rate is dynamically adjusted during fast-forward or rewind operations. The system transitions from a first playback rate (e.g., 2x, 4x, 8x) to a second playback rate (e.g., 1x, 0.5x) when approaching a previously viewed position, enabling both rapid navigation and precise positioning
Solution Approach 2:
The system uses viewing history data as feedback to determine when to adjust playback rate. By monitoring the distance between current playback position and previously viewed positions, the system automatically adjusts rate to prevent overshooting desired positions
2Adaptability or versatility
If conventional systems slow down fast-forward or rewind operation during predetermined segments, then user interest in important content is improved, but flexibility in adapting to actual user behavior deteriorates
Solution Approach 1:
The system automatically identifies important segments based on user viewing behavior without requiring manual marking. By analyzing viewing history to detect positions where users pause, rewind, or fast-forward, the system self-adapts to user interests and dynamically adjusts playback rate around these positions
3Loss of time
If fast-forward or rewind operation is performed at high rate, then time to reach desired position is reduced, but overshooting desired position increases
Solution Approach 1:
The system dynamically changes playback rate based on proximity to previously viewed positions. High rate is used when far from target positions to minimize time loss, while low rate is automatically engaged when approaching target positions to prevent overshooting and ensure accurate positioning

AI summary
Systems and methods for performing fast-access playback operations are provided. A viewing history is stored that includes a plurality of play positions within a media asset that are associated with user interactions. A user request is received to perform a fast-access playback operation while accessing the media asset. While performing the fast-access playback operation at a first rate, it is determined whether a current fast-access playback position is within a threshold distance from a given one of the plurality of play positions stored in the viewing history. The fast-access playback operation is slowed down from the first rate to a second rate while the current fast-access playback position is within the threshold distance from the given play position.
