Metadata-Driven Audio Search Across Multiple Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio entertainment systems do not allow users to easily search for and access specific content across multiple sources, requiring additional cognitive effort to select both the source and content, and lack mechanisms for locating music by genre independently of the source.
Innovation Solution
A system utilizing metadata to enable users to select audio content based on preferences such as artists or genres, allowing playback from various sources like AM/FM, HD-Radio, SDARS, and local storage, while also creating personalized radio stations with integrated localized information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually select both the source and content for audio playback, then the system can play audio from multiple sources, but the cognitive effort and time required increases
Solution Approach 1:
The system automatically scans and monitors multiple audio sources for content matching user-selected criteria without requiring manual source selection. The processor continuously analyzes metadata from broadcast and stored audio sources, automatically identifying and playing relevant content based on user preferences for artists, genres, or time periods.
Solution Approach 2:
The system pre-scans and indexes metadata from multiple audio sources in advance, organizing content by artist, genre, and time period before user request. This preliminary organization allows instant retrieval and playback of matching content without requiring users to search through multiple sources at the moment of selection.
2Adaptability or versatility
If the system searches for content across multiple sources, then content accessibility improves, but the system complexity increases
Solution Approach 1:
The system employs a universal metadata analysis approach that works across all audio sources (broadcast and stored) using the same processing logic. The processor uses identical criteria-based matching algorithms regardless of the source type, simplifying the overall system architecture while maintaining multi-source capability.
Solution Approach 2:
The system uses metadata as an intermediary layer between the user and the actual audio content. By indexing and searching metadata rather than directly scanning audio streams, the system simplifies the complexity of multi-source searching while maintaining comprehensive content accessibility.
3Reliability
If the system monitors broadcast audio in real-time, then content freshness improves, but the time and processing resources increase
Solution Approach 1:
The system performs partial monitoring of broadcast audio by focusing only on specific time periods or genres that match user preferences, rather than continuously analyzing all broadcast content. This selective approach maintains content freshness for relevant material while reducing overall processing time and resource consumption.
4Adaptability or versatility
If the system stores audio from multiple sources, then content availability improves, but the storage requirements increase
Solution Approach 1:
The system extracts only the essential metadata (artist, genre, time period information) from audio sources for indexing and searching, rather than storing complete audio files. This extraction approach maintains content availability for searching and playback while dramatically reducing storage requirements compared to storing all source material.
Data Source
AI summary
Although current radio receivers support playback of audio from multiple sources, none support easy searching for content across these sources. There is no mechanism for locating specific content independent of the source that it is found on. The invention is to have an entertainment system which utilizes metadata to offer a feature that will allow the user to listen to any audio source based on their listening preference. This invention also allows the user of a radio receiver to be able to easily locate music of a particular genre without regard to the actual source. This invention further provides a mechanism for the music stored on a hard drive to be used to create a personalized radio station, complete with inserts of localized information.
