Audio Video Composition Synchronization via Remote Meta Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating and distributing audio and video compositions are limited in their ability to efficiently manage and synchronize audio and video elements, particularly in creating and sharing compositions across different devices, with a lack of flexibility in editing and updating compositions in real-time.
Innovation Solution
A method and system for generating and distributing audio and video compositions that involve selecting audio tracks and videos, setting video masks based on audio tempo, and creating meta files to define composition parameters, allowing for real-time editing and sharing across devices, with a remote database managing and serving media content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If compositions are distributed across multiple devices, then user collaboration and accessibility are improved, but data synchronization and consistency become more complex
Solution Approach 1:
The patent introduces a remote database as an intermediary component that mediates between multiple computing devices. The database stores composition data and receives requests from devices, managing synchronization automatically. This intermediary absorbs the complexity of cross-device coordination, allowing individual devices to remain relatively simple while achieving complex collaborative functionality across the system.
2Reliability
If video masks are adjusted based on audio tempo, then synchronization between audio and video is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary analysis of audio tracks to determine tempo characteristics before video mask assignment. By pre-processing the audio data and storing tempo information, the system avoids repeated real-time analysis during composition creation. This preliminary action establishes synchronization parameters in advance, reducing processing time during actual composition assembly while maintaining reliable audio-video synchronization.
3Ease of operation
If real-time editing capabilities are enabled, then user flexibility and creativity are improved, but system performance and stability may deteriorate
Solution Approach 1:
The system implements feedback mechanisms that monitor system state during real-time editing operations. When editing operations approach thresholds that could compromise stability, the feedback system provides controlled responses such as operation queuing, resource management adjustments, or user notifications. This feedback loop enables flexible real-time editing while maintaining system stability through automated control measures.

AI summary
One variation of a method for distributing a composition of audio and visual media includes: at a first computing device, generating a first meta file for a first composition, including pointers to an audio track and pointers to, positions and durations of video masks for, and an order for a set of videos; storing the first meta file and a portion of a private video, in the set of videos, in a remote database; serving the audio track and the set of videos to a second computing device for playback at the second computing device according to the first meta file; in response to modification of the first composition at the second computing device, generating a second meta file for a second composition defining a modified arrangement of the first composition; and storing the second meta file for local playback of the second composition at a third computing device.
