Vehicle AVN Playlist Preference for Duplicate Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
AVN systems for vehicles often play the same media repeatedly without user selection, lacking the ability to selectively play media from various sources based on user preferences.
Innovation Solution
An AVN system with a communication module, display module, output module, and processor that allows users to designate a play preference mode, such as 'fidelity first' or 'data saving,' to selectively play media from various sources, integrating media from external memories, streaming servers, and mobile devices, and managing lists to prioritize high sound quality or low CPU usage media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the AVN system plays all media in the playlist, then the system provides comprehensive media playback from various sources, but the same media may be repeatedly played without user selection
Solution Approach 1:
The system automatically detects duplicate media in the playlist and selectively plays only one instance of each, eliminating the need for manual user selection. The processor identifies same media from different sources (USB, SD card, streaming server, Bluetooth device) and autonomously manages playback to avoid repetition.
2Adaptability or versatility
If the system integrates media from multiple sources (USB, SD card, streaming server, Bluetooth device), then the media variety increases, but the complexity of managing and selecting media increases
Solution Approach 1:
The system merges media from multiple sources (USB drive, SD card, streaming server, Bluetooth device) into a unified playlist managed by a single processor. The processor consolidates media identification, duplication detection, and playback control into one integrated management system, reducing operational complexity despite multiple input sources.
3Productivity
If the system plays all media including duplicates, then no media is missed, but redundant playback occurs consuming unnecessary time and resources
Solution Approach 1:
The system extracts and removes duplicate media entries from the playlist before playback. The processor identifies same media (by title, artist, album) from different sources and excludes redundant instances, ensuring each unique media file is played only once while maintaining complete media coverage.

AI summary
An audio video navigation (AVN) system for a vehicle includes a communication module configured to communicate with media sources providing media, a display module configured to display a playlist of the media, an output module configured to output the media, and a processor configured to selectively play any one of the same media based on a predetermined play preference mode when the same media are present in the playlist when the media in the playlist are played.
