Slide-Based Multimedia Container for Synchronized Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multimedia presentations face challenges in effective distribution due to large combined image frames, network constraints leading to latency and synchronization issues, and inability to modify or interact with individual components post-merging, especially in areas with underdeveloped data transmission infrastructure.
Innovation Solution
A system and method for generating and transmitting multimedia content by segmenting audio, video, and marking data per slide, associating them with time information, and synchronizing their playback on audience devices, allowing separate transmission and reproduction of individual components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If audio, video, and marking data are combined into a single multimedia file, then the presentation is easier to distribute, but the file size becomes large and network transmission becomes inefficient
Solution Approach 1:
The patent divides the multimedia presentation into separate components: slide data, audio data, video data, and marking data. Each component is stored and transmitted independently rather than being combined into a single large file, thereby reducing the size of each individual file while maintaining ease of distribution through modular packaging.
2Device complexity
If audio, video, and marking data are combined into a single multimedia file, then the presentation structure is simplified, but individual components cannot be modified or interacted with separately
Solution Approach 1:
The patent segments the presentation into distinct data types (slides, audio, video, markings) that can be independently accessed, modified, and interacted with. This segmentation enables selective editing of individual components without affecting the overall presentation structure, thereby improving adaptability while maintaining structural simplicity through standardized data organization.
Solution Approach 2:
The patent creates a universal data structure that can accommodate multiple types of content (slides, audio, video, markings) in a standardized format. This multi-functional framework allows different components to be handled uniformly by the system while still permitting individual modification and interaction, resolving the contradiction between structural simplicity and component versatility.
3Ease of manufacture
If multimedia data is transmitted as combined image frames, then transmission is straightforward, but synchronization between audio, video, and slides becomes difficult
Solution Approach 1:
The patent transmits audio, video, and slide data as separate segmented streams rather than combining them into image frames. Each stream includes timing metadata that enables independent transmission and reliable synchronization at the receiving end, thereby maintaining transmission simplicity while improving synchronization accuracy through structured data organization.
Solution Approach 2:
The patent introduces a timing synchronization mechanism that acts as an intermediary between separate data streams. This mediator uses timestamp metadata embedded in each data segment to coordinate the playback of slides, audio, and video, ensuring accurate synchronization without requiring the data to be pre-combined into image frames.
4Quantity of substance
If multimedia data is compressed to reduce file size, then distribution becomes more efficient, but playback quality and synchronization precision deteriorate
Solution Approach 1:
The patent applies segmentation to separate different types of data (audio, video, slides) and applies appropriate compression techniques to each segment based on its specific requirements. This allows optimization of data volume for each component while preserving the quality and precision needed for accurate playback and synchronization, rather than applying uniform compression that would degrade overall quality.
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.
