Audio Sync Priority Segmentation for In-Vehicle Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current file synchronization applications are inefficient in terms of computing resource consumption, particularly when downloading large numbers of data files, and can be time-consuming, especially over congested networks or when the connection breaks, leading to user discouragement from backing up data.
Innovation Solution
Implementing a priority synchronization method that selects a subset of data files based on access patterns, downloading priority files in their original format and non-priority files in a downgraded format, such as thumbnails or lower resolution, to minimize time and bandwidth consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data files are downloaded during synchronization, then complete data backup is achieved, but download time and network bandwidth consumption increase significantly
Solution Approach 1:
The patent segments the data files into two distinct categories: priority files and non-priority files. Priority files are downloaded in their original format to ensure complete backup of essential data, while non-priority files are downloaded in a downgraded format (such as thumbnails for images or lower resolution for videos). This segmentation allows the system to achieve complete data backup while significantly reducing the total download time and network bandwidth consumption by downloading only essential portions of non-priority files during the synchronization process.
Solution Approach 2:
The patent applies local quality by downloading different quality versions of files based on their priority classification. Priority files receive full-quality downloads in their original format, while non-priority files receive downgraded quality versions (thumbnails, lower resolution). This approach ensures that the most important data is fully preserved while reducing overall data transfer requirements, thereby minimizing download time while maintaining backup completeness for essential files.
2Reliability
If all data files are downloaded during synchronization, then complete data backup is achieved, but network bandwidth consumption increases significantly
Solution Approach 1:
The patent segments the data files into priority and non-priority categories, downloading only essential portions of non-priority files in downgraded format. This segmentation reduces the total volume of data transmitted over the network while ensuring that priority files are fully backed up, thereby achieving complete backup of essential data with significantly reduced network bandwidth consumption.
Solution Approach 2:
The patent implements local quality by transmitting different quality versions of files based on their priority level. Priority files are transmitted in full quality, while non-priority files are transmitted in downgraded quality (thumbnails, lower resolution). This approach minimizes network bandwidth consumption by reducing the size of transmitted data while maintaining backup completeness for priority files.
3Reliability
If synchronization is performed over congested networks or with low bandwidth, then data backup can be achieved, but download time becomes excessively long
Solution Approach 1:
The patent segments files into priority and non-priority categories, downloading only essential portions of non-priority files in downgraded format. This segmentation reduces the total data transfer volume, enabling synchronization to complete successfully even over congested networks with limited bandwidth, while maintaining acceptable synchronization speeds by focusing resources on priority files.
Solution Approach 2:
The patent applies local quality by transmitting downgraded versions of non-priority files (thumbnails, lower resolution) instead of full-quality files. This approach reduces the amount of data that needs to be transmitted over congested networks, thereby improving synchronization speed while ensuring that priority files are fully backed up and non-priority files are partially backed up in a space-efficient manner.
4Reliability
If connection between remote server and user device breaks during download, then data transfer is interrupted, but reconnection requires downloading all files again
Solution Approach 1:
The patent segments the download process into priority files and non-priority files, with further segmentation of non-priority files into different quality levels. This segmentation allows the system to resume downloads more efficiently after connection interruptions by prioritizing the resumption of priority files and using the already-downloaded downgraded versions of non-priority files as a baseline, reducing the need to re-download everything from scratch.
5Reliability
If synchronization application downloads all changed files, then up-to-date backup is achieved, but computing resources are consumed excessively
Solution Approach 1:
The patent segments the file processing into priority and non-priority categories, applying different download and processing strategies to each segment. Priority files are downloaded in full and processed completely, while non-priority files are downloaded in downgraded format with reduced processing requirements. This segmentation reduces computing resource consumption by minimizing the amount of data that needs to be fully processed while maintaining backup currency for essential files.
Solution Approach 2:
The patent implements local quality by downloading and processing downgraded versions of non-priority files instead of full-quality files. This approach reduces computing resource consumption during the synchronization process by decreasing the amount of data that needs to be transmitted, stored, and processed, while still maintaining backup currency for priority files and providing partial backup for non-priority files.
Data Source
AI summary
Technology is disclosed for synchronizing audio files from a computing device of a user to an in-vehicle computing device, such as an audio system, installed in an automobile. In one example, when the user plays an audio file on the in-vehicle computing device from the computing device, the audio file is copied at the in-vehicle computing device. After copying the currently playing audio file, the in-vehicle computing device can also copy at least some of the audio files from the computing device. The in-vehicle computing device computes a popularity score of each of the audio files based on an access pattern of the audio files, and categorizes them into priority files and low-priority files based on their popularity score. While the in-vehicle computing device copies the priority files, it copies metafiles of the low-priority files. The metafiles can include information such as a title, artist, etc. of the audio files.
