Multimedia Presentation Segmentation for Bandwidth-Constrained Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia presentations face challenges in effective distribution due to large combined image frames and networking constraints, leading to difficulties in data transmission and synchronization issues.
Innovation Solution
A system and method for generating, transmitting, and reproducing multimedia presentations by segmenting audio, video, and marking data into smaller pieces, associating them with specific slides, and transmitting with time information for synchronized playback on audience devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual contents (video and markings) are combined together to form image frames, then the presentation can be reproduced on audience devices, but the size of the combined image frames becomes relatively large
Solution Approach 1:
The patent segments the combined image frame into separate components: video data and marking data. Instead of transmitting one large combined image frame, the system transmits separate video portions and marking portions that can be independently processed and combined at the reproduction device, significantly reducing the data size while maintaining reproduction capability.
2Reliability
If combined image frames are transmitted to audience devices, then multimedia presentation can be reproduced, but effective distribution becomes difficult in areas with poor data transmission infrastructure
Solution Approach 1:
By segmenting the combined image frame into separate video and marking components, the patent enables flexible distribution strategies. The segmented data can be transmitted through multiple channels, prioritized according to importance, and adapted to different network conditions, improving distribution capability in areas with poor infrastructure.
Solution Approach 2:
The patent applies different quality levels or transmission priorities to different segments of the presentation data. Critical components can be transmitted with higher priority or quality, while less critical components can be transmitted with lower priority, allowing the system to adapt to varying network conditions and infrastructure capabilities.
3Reliability
If video and markings are combined into image frames, then the presentation can be displayed, but the components become not separable in their original forms
Solution Approach 1:
The patent maintains separability of video and marking components by segmenting the data structure. Each component is transmitted independently with its own data structure, allowing the reproduction device to process and combine them without requiring complex integrated formats, thus reducing overall data structure complexity while maintaining display capability.
4Reliability
If multimedia data is transmitted individually with slide information and time information, then synchronized playback can be achieved, but the transmission process becomes more complex
Solution Approach 1:
The patent incorporates time information and slide information into the multimedia data segments in advance, before transmission. This preliminary tagging allows the reproduction device to automatically synchronize playback without requiring complex real-time coordination or processing, reducing transmission process complexity while maintaining synchronization accuracy.
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.
