Multimedia Presentation Segmentation for Bandwidth Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia presentation distribution methods face challenges in separating and efficiently transmitting multimedia content components, such as audio, video, and markings, due to large file sizes and synchronization issues, especially in areas with poor data transmission infrastructure.
Innovation Solution
A method and system for generating, transmitting, and reproducing multimedia presentations by segmenting audio, video, and marking data into individual components associated with specific slides, with time information, allowing for separate transmission and synchronization at the audience device, enabling efficient distribution and reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multimedia content components (audio, video, markings) are combined together to form image frames for transmission, then the presentation can be reproduced seamlessly, but the file size becomes large and transmission becomes difficult in areas with poor data infrastructure
Solution Approach 1:
The patent segments multimedia content into separate components (audio data, video data, marking data) associated with specific slides, rather than combining them into single large image frames. Each component is transmitted independently, reducing overall file size and enabling efficient transmission over bandwidth-constrained networks while maintaining the ability to reproduce the complete presentation seamlessly at the receiving end.
2Quantity of substance
If multimedia content components are separated into individual files for transmission, then file size is reduced and transmission is more efficient, but synchronization issues arise during reproduction
Solution Approach 1:
The patent incorporates time information into each multimedia component (audio, video, markings) during the segmentation phase. This preliminary tagging of temporal data enables the receiving device to automatically synchronize the playback of separate components without requiring complex real-time coordination, thus maintaining reliable reproduction while benefiting from reduced file sizes.
3Ease of operation
If visual contents (video and markings) are combined with presentation slides to form image frames, then the presentation can be displayed together, but the combined frames are large in size even when compressed
Solution Approach 1:
The patent separates visual contents (video and markings) from presentation slides, transmitting them as distinct multimedia components rather than combining them into single image frames. This segmentation reduces the size of each transmitted file while enabling the receiving device to integrate and display all components together, achieving both ease of operation and reduced file size.
Data Source
AI summary
Systems and methods are disclosed for generating, transmitting, reproducing, and integrating multimedia contents for a presentation. An example method includes providing a presentation document comprising a plurality of slides (e.g., a first slide and a second slide), and generating multimedia data of a presentation, including a first audio datum, a first video datum, a second audio datum and a second video datum. The multimedia data may be transmitted to an audience device for reproduction of the multimedia presentation such that: each of the first audio datum, the first video datum, the second audio datum and the second video datum is individually transmitted to the audience device, along with slide information indicative of one of the plurality of slides with which it is associated and time information indicative of a time at which each multimedia datum is to be played back.
