Collaborative Presentation Playback With Synchronous Media Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack the capability to efficiently create, edit, and interact with information presentations in real-time, particularly in a collaborative manner, and fail to provide seamless integration of both interactive and non-interactive assets.
Innovation Solution
A system and user interface that allows for the creation, playback, and interaction with information presentations using a creation/playback application that supports editor, runtime, and collaboration modes, enabling real-time and non-real-time collaboration, and integrates non-interactive assets like audio and video streams with interactive widgets such as chat, editing tools, and multimedia elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a system integrates both interactive widgets and non-interactive assets for presentations, then the versatility and interaction capability are improved, but the device complexity increases
Solution Approach 1:
The system divides the presentation platform into distinct functional modules: a timeline module for sequencing, an asset library module for storing non-interactive assets (videos, audio, images), a widget module for interactive elements (polls, quizzes, chat), and a playback engine. Each module operates independently but communicates through standardized interfaces, allowing the system to handle diverse presentation types without monolithic complexity
Solution Approach 2:
The system implements a universal asset interface that allows different types of content (videos, audio files, images, interactive widgets) to be managed through common operations. The timeline module can sequence both passive media and interactive elements using the same temporal framework, while the playback engine handles both types of assets through unified control mechanisms, reducing the need for separate specialized systems
2Ease of operation
If real-time collaboration features are added to the presentation system, then the ease of operation is improved, but the loss of time for data synchronization increases
Solution Approach 1:
The system establishes collaboration protocols and synchronization mechanisms in advance during system initialization. User permissions, conflict resolution rules, and data versioning strategies are pre-configured, allowing real-time collaborators to immediately begin working without negotiation overhead. The timeline module pre-allocates temporal slots for collaborative edits to minimize conflicts
Solution Approach 2:
The system implements continuous feedback loops through real-time status indicators that show current presentation state, active editors, and synchronization progress. When changes occur, the system immediately notifies all connected users and automatically reconciles conflicts using pre-established rules. The playback engine monitors asset modifications and triggers selective re-synchronization only for affected portions, rather than full system updates
3Productivity
If multiple assets and interactive elements are integrated into a single presentation, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The system merges the management of diverse assets (videos, audio, images) and interactive widgets into a single unified timeline interface. All elements are represented as timeline objects with consistent properties (start time, duration, visibility), allowing creators to sequence and control everything from one view. The asset library provides a common repository that both media files and interactive elements can draw from, eliminating the need for separate management systems
Data Source
AI summary
The disclosed technology includes systems and methods for synchronous delivery of a media file to multiple user computers. A first user computer can receive a first request for playing a media file at a first information display of the first user computer and can receive a second request for a synchronous session comprising synchronously displaying at least a portion of the media file at the first information display and a second information display of a second user computer. The second user computer can display content other than the media file on the second information display, receive the request from the first user computer to join the synchronous session, and enter the synchronous session. The method can include termination the synchronous session by at least terminating the synchronously displaying of the at least a portion of the media file at the first user computer and the second user computer.
