Automotive Audio Interface for Digital Music Organization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automobile audio systems face limitations in storage capacity, media fragility, and the need for physical media, making it difficult to access and organize large amounts of digital music, especially when users want to play downloaded music without requiring cassette or compact discs.
Innovation Solution
A system that uses a digital music device to access and organize compressed audio data, allowing users to create and switch between playlists based on track identification attributes such as title, artist, genre, and publication date, using a traditional automobile stereo interface, and emulating a disc changer to play music stored on a removable disk cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a disc changer with multiple physical discs is used to store music, then the storage capacity is limited to what fits on individual discs, but the system requires physical media that takes up space and can be damaged
Solution Approach 1:
The patent replaces physical media (cassettes, compact discs) with digital copies stored in memory. The system loads track identification information and audio data from the memory device into the audio processor, eliminating the need for physical media while maintaining the ability to store and play music collections.
Solution Approach 2:
The patent replaces the mechanical disc changer system with an electronic memory-based system. Instead of physically loading and changing discs, the system uses a memory device interface to load track data electronically, eliminating mechanical wear and physical media handling.
2Adaptability or versatility
If user-defined playlists are created manually to organize music, then the music can be organized by category, but creating and managing playlists takes considerable time and effort
Solution Approach 1:
The system automatically generates playlists by reading track identification information from the memory device and organizing tracks according to user-selected criteria (artist, album, genre, etc.) without requiring manual playlist creation. The audio processor handles the organization task automatically when the user selects a search criterion.
Solution Approach 2:
The system provides feedback to the user by displaying track identification information and allowing the user to select search criteria. Based on this input, the system automatically generates and presents organized playlists, creating an interactive feedback loop that simplifies music organization.
3Ease of operation
If traditional automobile stereos are used to play music, then the interface is familiar to users, but the system cannot access or organize large amounts of digital music data
Solution Approach 1:
The patent makes the traditional automobile stereo interface multi-functional by adding the ability to read track identification information from memory devices, search by various criteria, and automatically generate playlists. This allows the familiar interface to access and organize large digital music collections while maintaining ease of use.
Solution Approach 2:
The system dynamically adapts the traditional stereo interface to handle digital music data by implementing flexible search and playlist generation capabilities. The interface can switch between different search criteria and automatically reorganize music based on user preferences, making it adaptable to various music organization needs.
Data Source
AI summary
A system is disclosed that provides access to a large amount of content using a traditional interface. The system has many applications, one of which is for providing access to audio/visual content. Examples of audio/visual content includes compressed digital music data and video data. In one embodiment, the system receives an indication of a first mode, accesses a first playlist for the first mode, and plays tracks according to the first playlist. In this embodiment, each mode is associated with a different attribute, each mode includes one or more playlists of tracks, and each playlist of a particular mode is based on a different value for the attribute associated with the particular mode. Examples of attributes include artist, album, genre, etc. Thus, there can be an artist mode, an album node, a genre mode, etc. For example, each playlist in the artist mode is associated with a particular artist. All tracks on a given playlist in the artist mode would be associated with the same artists.
