Dynamic Presentation Generation via Audio-Visual Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for creating personalized audio-visual presentations are limited by the need for pre-recorded videos, which require significant bandwidth and are inefficient, especially when only minor personalization is needed, leading to excessive data transfer and storage requirements.
Innovation Solution
A method that generates and streams personalized audio tracks and visual slides dynamically, using pre-recorded audio clips and dynamically rendered slides, synchronized in real-time, reducing the need for continuous video streaming and minimizing bandwidth usage by transmitting only necessary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-recorded videos are used for personalized presentations, then personalization is achieved, but bandwidth consumption and storage requirements increase exponentially
Solution Approach 1:
The presentation is divided into separate audio track and visual slide components that can be generated and transmitted independently. Only the necessary slide images (not full video frames) are transmitted, significantly reducing bandwidth consumption while maintaining personalization capability through dynamic assembly of these segments.
Solution Approach 2:
Instead of creating and storing unique video files for each personalized presentation, the system uses templates for audio tracks and slide layouts that are dynamically filled with personalized data. This allows infinite personalization variants to be generated from a finite set of template copies, eliminating exponential storage requirements.
2Speed
If presentations are encoded as video at 25-30 frames per second, then smooth playback is achieved, but bandwidth efficiency deteriorates when slide presentations require less than 1 frame per second
Solution Approach 1:
The system changes the frame rate parameter from video standard (25-30 fps) to slide presentation standard (less than 1 fps), transmitting only when content changes are needed. This parameter adjustment maintains playback smoothness for actual content transitions while eliminating wasteful data transfer during static periods.
Solution Approach 2:
Instead of continuous video streaming, the system uses periodic transmission of slide images synchronized with audio playback. Slides are transmitted and displayed only when needed in the presentation sequence, creating a periodic rather than continuous data flow that matches the actual content delivery requirements.

AI summary
Techniques for collecting user data about a visitor to a website, and at least partially based thereon generating dynamically, on-the-fly, a series of visual slides and an accompanying, synchronized, audio track to enable an online presentation to be played for the visitor. After the presentation is played, or in the middle thereof, further user data can be collected from the visitor, and an additional presentation or a modification to the existing presentation can be played for the visitor. The presentation is composed of multiple sequential frames that each are composed of one or more audio files. Each visual slide has accompanying synchronization information that specifies which audio file is to be played at and at what point in the audio file.
