Media Playback Timing Management for Vehicle Navigation Audio Conflicts

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing navigation systems in electronic devices often cause conflicts between audio navigation directions and media content playback, leading to overlapping audio that disrupts the listening experience.

Innovation Solution

The system determines whether media playback will end within a predefined time threshold before navigation announcements and pauses the media playback until the announcement is complete, or reorders the playlist to match navigation announcement durations, or selects an alternate route with fewer navigation directions to minimize interruptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the volume of media content is lowered and navigation directions are overlapped, then navigation announcements can be delivered, but media content quality is compromised and listener frustration increases

Engineering Contradiction:

Improvenavigation announcement deliveryVSAvoidmedia content quality degradation

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system determines timing information for both media content and navigation announcements in advance, identifying potential overlaps before they occur. This allows proactive pausing of media content before navigation announcements begin, preventing quality degradation while ensuring navigation delivery.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies preliminary anti-action by pausing media content playback before navigation announcements start. This counteracts the potential harmful overlap by stopping the media content in advance, ensuring navigation announcements are delivered clearly without compromising media quality.

Inventive Principle:

Principle #9Preliminary anti-action

2Object-affected harmful factors

If media playback is paused during navigation announcements, then navigation directions can be delivered clearly, but media playback continuity is interrupted

Engineering Contradiction:

Improveaudio overlap preventionVSAvoidmedia playback continuity

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system continuously monitors the timing relationship between media content playback and navigation announcements. Based on this feedback, it dynamically determines when to pause and resume media content, optimizing the balance between clear navigation delivery and minimal disruption to media playback continuity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts media playback based on real-time navigation announcement timing. Rather than a fixed pause policy, the pause duration and timing are adaptively determined based on the specific timing information of each navigation announcement and the current media content state.

Inventive Principle:

Principle #15Dynamics

3Productivity

If the system selects alternate routes with fewer directions, then navigation announcements are reduced and media content interruptions are minimized, but route optimization may be compromised

Engineering Contradiction:

Improvemedia content uninterrupted playbackVSAvoidroute selection flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system changes the parameter being optimized from purely route efficiency to a composite metric that balances route quality with media playback continuity. By considering both the number of navigation directions and media content timing, the system selects routes that minimize interruptions while maintaining acceptable navigation performance.

Inventive Principle:

Principle #35Parameter changes

AI summary

Systems and methods are disclosed herein for providing uninterrupted media content during vehicle navigation. The disclosed techniques herein discuss determining directions from route data and navigation announcements for each of the directions. For each navigation announcement, a determination is made whether current playback of a media asset in a playlist ends within a predefined time threshold before the navigation announcement. In a positive determination, the playback of the playlist is paused until the navigation announcement has elapsed.
