In-Vehicle Image Supplement System Fallback Hierarchy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle audio systems often lack immediate display of album cover images or other relevant imagery during media playback, leading to a lack of visual information and aesthetics when content is being played.
Innovation Solution
The system determines if primary or secondary images are available in the metadata or stored locally/remotely, using a priority scheme to display higher priority images such as album cover, artist, genre, or station logos, and retrieves and replaces lower priority images with higher ones as they become available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system waits for album cover images to be included in metadata before displaying them, then image accuracy is improved, but image availability is worsened
Solution Approach 1:
The system performs preliminary actions by checking multiple image sources (metadata, local storage, remote servers) in advance and establishing a fallback hierarchy before playback begins. This ensures that an image is ready for display without waiting for metadata to arrive, resolving the contradiction between accuracy and availability.
Solution Approach 2:
The patent introduces intermediary image sources (local storage database, remote server) that mediate between the metadata and the display device. When metadata images are unavailable, these intermediaries provide alternative images, ensuring continuous image availability while maintaining accuracy through a structured fallback process.
2Reliability
If the system uses a hierarchical image selection process with multiple fallback options, then image availability is improved, but system complexity is worsened
Solution Approach 1:
The image selection process is segmented into distinct hierarchical levels (metadata source, local storage, remote server, placeholder). Each segment handles a specific fallback scenario, making the complex process manageable and systematic. This segmentation resolves the contradiction by organizing complexity into structured, manageable segments.
Solution Approach 2:
The system changes the parameter of image source priority dynamically based on availability. By establishing a predefined hierarchy of image sources with different priorities, the system manages complexity through parameter changes rather than complex decision logic, improving availability while controlling system complexity.
3Loss of information
If the system retrieves and displays alternative images when primary images are unavailable, then visual information is improved, but data processing time is worsened
Solution Approach 1:
The system performs preliminary checks of local storage and establishes image fallback options before playback begins. By preparing alternative images in advance and checking their availability proactively, the system minimizes processing delays during actual playback, resolving the contradiction between providing visual information and minimizing processing time.
Solution Approach 2:
When metadata images are unavailable, the system quickly skips to alternative image sources without prolonged waiting. The hierarchical structure enables rapid progression through fallback options, reducing the time lost in data processing while ensuring visual information is ultimately provided.
Data Source
AI summary
Systems and methods for providing an in-vehicle image supplement are disclosed. One embodiment includes receiving a broadcast media signal that includes a content portion and a metadata portion, determining whether a primary image is included in the metadata portion, and in response to determining that the primary image is included in the metadata portion, providing the primary image for display. Additionally, in response to determining that the primary image is not included in the metadata portion, some embodiments include determining whether the primary image is otherwise available and in response to determining that the primary image is otherwise available, retrieving the primary image and providing the primary image for display. In response to determining that the primary image is not otherwise available, some embodiments include determining whether a secondary image is available, retrieving the secondary image, and providing the secondary image for display.
