Audio Video Synchronization - A simplified explanation of the abstract
This abstract first appeared for US patent application 18623733 titled 'Audio Video Synchronization
The patent application describes systems, methods, and apparatuses for detecting synchronization errors between audio and video signals. Scene changes can be identified using anchor frames, and offsets between a scene change in a video signal and changes in audio levels can indicate synchronization errors.
- Anchor frames are used to detect scene changes in video signals.
- Offsets between video scene changes and audio level variations can indicate synchronization errors.
- The technology aims to improve the alignment of audio and video signals for better synchronization.
Potential Applications:
- Film and television production
- Video editing software
- Live broadcasting systems
Problems Solved:
- Ensuring accurate synchronization between audio and video signals
- Detecting errors in multimedia content production
Benefits:
- Improved viewing experience for audiences
- Enhanced quality of multimedia content
- Streamlined production processes
Commercial Applications:
- Video production companies
- Streaming platforms
- Broadcasting networks
Questions about Synchronization Errors: 1. How do synchronization errors impact the quality of multimedia content?
- Synchronization errors can lead to audio and video being out of alignment, resulting in a poor viewing experience for audiences.
2. What are some common causes of synchronization errors in audio and video signals?
- Synchronization errors can occur due to transmission delays, processing issues, or equipment malfunctions.
Original Abstract Submitted
Systems, methods, and apparatuses are described for detecting synchronization errors between audio and video signals. Scene changes may be detected based on anchor frames. Offsets between a scene change in a video signal and a reduced audio level or burst of high audio level in the audio signal may indicate a synchronization error.
