Videoconferencing Content Sharing Preserving Original Format
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconferencing technologies degrade the quality of presented content by converting it into compressed video, leading to reduced resolution and bit rate, which affects the clarity and effectiveness of multimedia presentations.
Innovation Solution
The system allows content to be transmitted and presented in its original format, using a content transmitting endpoint to send files like PDFs and spreadsheets directly to receiving endpoints, along with control signals, maintaining the original quality and enabling synchronized presentation across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is converted to video stream by capturing screen image and compressing with encoder, then content can be transmitted over network, but content quality degrades with reduced resolution and bit rate
Solution Approach 1:
The patent extracts the content data from the video stream conversion process. Instead of capturing screen images and encoding them as video, the system separates content files (PDFs, spreadsheets, presentations) from the video stream and transmits them as native data files through a dedicated content sharing mechanism, preserving original quality while enabling network transmission
Solution Approach 2:
The patent introduces an intermediary content sharing layer between the presenter's computer and receiving endpoints. This intermediary system handles content transmission separately from the video conference stream, using file transfer protocols and synchronized display mechanisms to deliver high-quality content without degradation
2Adaptability or versatility
If content is transmitted as separate stream with different channel, then content can be delivered to multiple endpoints, but system complexity increases with additional encoding and transcoding requirements
Solution Approach 1:
The patent creates a universal content delivery system that can serve multiple endpoint types simultaneously. The content sharing mechanism is designed to work with various receiving endpoints (computers, mobile devices, displays) without requiring device-specific encoding or transcoding, as content is transmitted in native formats that can be rendered by diverse devices
Solution Approach 2:
The patent uses file copying mechanisms rather than video encoding for content transmission. Content files are copied from the presenter's system to receiving endpoints through network protocols, eliminating the need for complex encoding and transcoding operations while enabling multi-endpoint delivery
3Loss of energy
If frame rate is reduced to 1-10 frames per second for content encoding, then bandwidth consumption decreases, but content clarity and effectiveness are reduced
Solution Approach 1:
The patent replaces the mechanical video encoding system with a digital file transfer system. Instead of using video encoders that capture frames at low rates, the system uses file transfer protocols to transmit complete content files, eliminating the need for frame-based encoding and associated bandwidth limitations while preserving full content clarity
Data Source
AI summary
Content presented in association with a transmitting endpoint is obtained by the transmitting endpoint and transmitted to a receiving endpoint of a videoconference, along with associated information regarding interaction of a presenter with the content at the transmitting side. The receiving endpoint presents the presented content obtained from the transmitting endpoint similar to the presentation format at the transmitting side. Where the original presentation format is not suitable for transmission, a video image of the content in the original presentation format may be transmitted. An intermediate control unit, such as a multipoint control unit, may relay content and associated information between transmitting and receiving endpoints.
