Multi-Channel Video Compilation via Audio Fingerprint Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video-sharing platforms like YouTube and Vimeo do not provide convenient mechanisms to present distinct but related video segments in a continuous video stream, due to storage and upload limitations, making it difficult for users to watch events such as concerts or sporting events without interruptions.
Innovation Solution
A system and method for compiling and playing multi-channel videos by aggregating distinct video segments from different sources into a continuous stream, using a video aggregation interface, alignment engine, and multi-channel video player to align and switch between video segments automatically or manually, providing a seamless viewing experience with additional perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple video segments are uploaded to video-sharing websites, then the coverage of events is improved, but the convenience of continuous playback deteriorates due to upload limits and storage constraints
Solution Approach 1:
The system divides a complete event recording into multiple video segments captured by different cameras or recording devices. Each segment is independently uploaded and stored, then automatically reassembled through audio fingerprint correlation to form a continuous multi-channel video playback experience.
Solution Approach 2:
The patent introduces an intermediary processing system that uses audio fingerprint correlation to match and align video segments from different sources. This intermediary layer automatically synchronizes segments based on their audio content, enabling seamless continuous playback without requiring manual intervention or breaking the viewing experience.
2Quantity of substance
If video segments are divided due to storage limits, then the storage requirement per device is reduced, but the viewing experience is fragmented requiring manual selection of multiple segments
Solution Approach 1:
The system performs preliminary actions by pre-processing video segments to extract audio fingerprints and store them in a correlated structure. This preparation work is done in advance so that when playback is requested, the system can automatically assemble the correct sequence of segments without requiring real-time manual selection or user intervention.
Solution Approach 2:
The patent implements a feedback mechanism where the system automatically correlates audio fingerprints from different video segments, identifies their temporal relationships, and uses this information to automatically sequence and playback segments in the correct order, eliminating the need for manual segment selection by the user.
3Quantity of substance
If multiple video sources are aggregated, then the completeness of event coverage is improved, but the complexity of aligning and synchronizing segments increases
Solution Approach 1:
The patent replaces complex mechanical or manual alignment processes with an automated audio fingerprint correlation system. Instead of manually synchronizing video segments based on visual cues or timestamps, the system uses digital audio fingerprinting technology to automatically identify and align segments based on their audio content, significantly reducing the complexity of the alignment process.
Solution Approach 2:
The system changes the parameter used for alignment from visual or temporal metadata to audio fingerprint correlation. By transforming the alignment problem into an audio pattern matching problem, the system can automatically handle multiple video sources with different timestamps and synchronization references, simplifying the overall alignment complexity.
Data Source
AI summary
A system and method including retrieving a multi-channel video file with a first video segment and a second video segment; assigning a rank to the first video segment and second video segment; and rendering at least the first and second video segment in a player interface, synchronized to a timeline of the multi-channel video file, and comprising: playing the first video segment in an active stream, progressing a timeline of the multi-channel video file when video is played in the active stream, when the timeline progresses to a synchronized time of the second video segment, playing the second video segment in the active stream and displaying the first video segment as a selectable video channel if the rank of the second video segment is greater than the rank of the first video segment, and otherwise displaying the second video segment as a selectable video channel.
