Content-Adaptive Media Adjustment for Audio Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital content playback technologies face challenges in increasing playback rates without causing audio distortion or quality degradation, such as pitch changes and audio choppiness, when accelerating media content.
Innovation Solution
A content-adaptive method and system that adjusts the playback length of digital content items by selectively removing portions of audio and video content, based on tempo analysis and time allocation scores, to achieve higher playback rates without introducing unwanted side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the playback rate of audio is increased to reduce playtime, then the consumption time of digital content is reduced, but audio distortion occurs such as pitch changes and cartoon-like voice quality
Solution Approach 1:
The patent divides the audio content into multiple segments and processes each segment independently. By analyzing tempo and identifying silent portions within each segment, the system can remove only the necessary audio portions rather than uniformly compressing the entire audio stream, thereby avoiding pitch distortion and maintaining audio quality while reducing playback time.
Solution Approach 2:
The patent extracts and removes silent or less important audio segments from the content while preserving the essential audio information. This selective extraction allows the content to be played back faster without the harmful effects of uniform speed acceleration, as only non-critical portions are removed.
2Productivity
If the playback rate is accelerated to consume more content in a given time period, then productivity increases, but the quality of media content is time diminished
Solution Approach 1:
The patent dynamically adjusts the playback rate by removing audio segments based on tempo analysis and time allocation scores. Rather than applying a fixed acceleration rate, the system adaptively determines which segments to remove and by how much, allowing flexible content consumption speed adjustment while maintaining quality standards for important content portions.
Solution Approach 2:
The patent changes the temporal parameters of audio segments by removing portions based on calculated time allocation scores and tempo. This parameter modification approach allows the system to reduce overall content duration while preserving the quality and integrity of critical audio segments, thereby improving productivity without sacrificing content quality.
3Duration of action of moving object
If uniform compression is applied to reduce content length, then playtime is reduced, but audio choppiness and quality degradation occur
Solution Approach 1:
The patent applies different processing treatments to different audio segments based on their local characteristics such as tempo, silence detection, and time allocation scores. Instead of uniform compression, each segment is analyzed and processed individually, removing only the necessary portions while preserving the quality and continuity of important audio content, thereby maintaining audio quality consistency while reducing overall duration.

AI summary
Disclosed herein is a content-adaptive digital media content adjustment system, method and architecture. Playback rate of a media content item comprising audio and video content can be increased by removing a portion of the content item's audio content and a corresponding portion of the content item's video content. An increased playback rate of a multimedia content item is accomplished by decreasing the length of the multimedia content item by removing portions of the multimedia content item's audio and video content.
