Multimedia File Title Sequence Auto-Skip via Audio Feature Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia players lack the ability to automatically skip the title sequence of multimedia files, forcing users to manually set a fixed time, which is inefficient when dealing with varying lengths of summaries or advertisements.
Innovation Solution
A method that analyzes the first portion of a multimedia file to determine its feature data, allowing the electronic device or multimedia file sharing system to automatically skip the title sequence and display the substantial portion of subsequent files by matching this data, enabling precise identification of the beginning time of the substantial content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed time setting operation is used to skip content, then the operation is simple, but the skipping length cannot be automatically adjusted according to whether the multimedia file contains antecedent summary or advertisements
Solution Approach 1:
The system automatically analyzes multimedia files to detect antecedent summaries and advertisements, then self-adjusts the skipping length without requiring user input. The electronic device or server autonomously determines the optimal skip point by comparing audio signal waveforms and matching feature data, making the system adapt to different file types and lengths automatically.
Solution Approach 2:
The system performs preliminary analysis of multimedia files before playback to identify and mark the portions containing antecedent summaries or advertisements. By pre-processing the audio signal waveforms and storing feature data, the system prepares the skipping information in advance, enabling automatic adaptation during playback without real-time processing delays.
2Ease of operation
If manual skipping is required for each episode, then the system is simple, but the user experience deteriorates due to repetitive title sequences
Solution Approach 1:
The system creates a copy of the audio signal waveform feature data from the first multimedia file and uses this copied data to match and identify identical title sequences in subsequent files. By comparing the copied feature data against new files, the system automatically detects and skips repetitive content without requiring manual user input for each episode.
Solution Approach 2:
The system establishes a universal skipping mechanism that works across multiple multimedia files of the same type (e.g., all episodes of a TV series). By analyzing the feature data from one file and applying it universally to match and skip identical sections in subsequent files, the system eliminates repetitive manual operations while maintaining ease of use.
3Reliability
If the entire multimedia file is downloaded and stored, then the file is available for offline viewing, but the storage space is wasted on portions that will be skipped
Solution Approach 1:
The system extracts and identifies the specific time portions containing title sequences, antecedent summaries, and advertisements by analyzing audio signal waveforms. Once these portions are identified and marked, the system can exclude them from download or storage, extracting only the substantial content portions that users actually need to view, thereby eliminating storage waste while maintaining reliability for essential content.
Solution Approach 2:
The system segments the multimedia file into distinct portions: skipped portions (title sequences, advertisements, antecedent summaries) and substantial content portions. By dividing the file structure this way, the system can selectively download or store only the substantial content segments, reducing storage requirements while ensuring reliable availability of the important viewing content.
Data Source
AI summary
A method for skipping title sequence of a multimedia file and an electronic device are provided. The method includes: obtaining a first portion feature data of a first multimedia file; obtaining a beginning time of a second portion of a second multimedia file according to the first portion feature data; and skipping a first portion of the second multimedia file prior to the beginning time of a second portion, and displaying the second portion of the second multimedia file.
