Presentation Sharing via Network Packet Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current meeting technologies face inefficiencies in sharing live presentations across multiple screens and personal devices, limited user participation, and poor note-taking capabilities, especially due to high infrastructure costs and poor snapshot quality under varying lighting conditions.
Innovation Solution
A method and system that distribute live presentation content across multiple screens and personal devices via network packet data streams, allowing key elements to be captured, stored, and retrieved, enabling seamless sharing and note-taking without the need for complex infrastructure, and allowing personal devices to capture and store images of presentations independently of their location relative to the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional projection infrastructure is used to display presentations, then presentation visibility is achieved, but infrastructure cost and device complexity increase
Solution Approach 1:
The patent enables personal devices (smartphones, tablets, laptops) to serve dual purposes: as both presentation content sources and as display devices. This eliminates the need for dedicated projection infrastructure by making each participant's device a potential display terminal, thereby reducing infrastructure cost and complexity while maintaining presentation visibility
Solution Approach 2:
The system creates digital copies of presentation content and distributes them via network packets to multiple recipient devices. Instead of using a single physical projector to broadcast to all attendees, the presentation is copied and transmitted to each device individually, eliminating expensive projection equipment while achieving the same visibility goal
2Adaptability or versatility
If multiple screens are used to display presentation content, then user participation and viewing options improve, but device complexity and infrastructure requirements increase
Solution Approach 1:
Each recipient device autonomously receives, processes, and displays presentation content independently without requiring centralized control equipment. The devices self-configure as display terminals by joining the network broadcast, eliminating the need for complex video distribution switches or multiple projectors that would traditionally be required for multi-screen displays
Solution Approach 2:
The patent transitions from physical spatial distribution of displays (multiple projectors/screens requiring physical infrastructure) to network-based distribution where content flows through digital dimensions. Presentation content is transmitted via network packets across the digital realm, allowing any number of devices to display content simultaneously without adding physical infrastructure complexity
3Loss of information
If snapshots are taken of presentation content, then key elements can be captured for reference, but image quality deteriorates under varying lighting conditions
Solution Approach 1:
Instead of capturing images of the presentation display (which suffers from lighting and angle issues), the system copies the actual presentation data directly from the source device through the network. This digital copying preserves perfect image quality and all key elements without the degradation inherent in photographic snapshots taken under varying lighting conditions
Solution Approach 2:
The network transmission system acts as an intermediary that delivers pristine digital copies of presentation content directly to recipient devices. This intermediary pathway bypasses the need for optical capture (photography) entirely, ensuring that key elements are retained with perfect fidelity regardless of environmental lighting conditions
4Reliability
If a central authority controls information distribution, then information accuracy is maintained, but user participation and collaboration are limited
Solution Approach 1:
The system segments the traditional centralized information distribution model by allowing each participant's device to independently receive and display presentation content. Instead of one central authority controlling all information flow, the content is segmented and distributed to multiple independent nodes, maintaining accuracy through direct source transmission while enabling each user to control their own display and interaction
5Productivity
If presentation content is shared in real-time, then live collaboration is enabled, but network bandwidth and data transmission requirements increase
Solution Approach 1:
The system transmits only the necessary portions of presentation content to each device rather than duplicating the entire presentation stream to all recipients simultaneously. By implementing partial transmission where devices receive content as needed and display what is relevant, the system enables live collaboration while reducing overall network bandwidth consumption compared to full-duplex real-time streaming to all devices
Data Source
AI summary
The present invention relates to methods and devices for sharing a presentation, allowing the presenter to capture and archive key elements of a meeting (KEMs) such as image frames for storage and later retrieval. The capture may be done via a device connected to one of a plurality of screens. The invention also allows the presentation to be followed on a personal device such as a smart phone, which can also access archived KEMs.
