Delivery Managing Device for Videoconferencing Drawing Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to distinguish between drawing information displayed only on an individual terminal and that displayed on another terminal, limiting interactivity and discussion efficiency in videoconferencing systems.
Innovation Solution
A delivery managing system that includes a delivery managing device, communication terminals, and a terminal managing device, which utilize a browser and encoder bridge unit to convert web content into video and sound data, allowing for distinguished display of drawing information on own and shared terminals through a communication network, enabling real-time communication and collaboration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If drawing information is displayed on multiple terminals, then interactivity and discussion efficiency are improved, but it becomes difficult to distinguish between drawing information displayed only on own terminal and that displayed on another terminal
Solution Approach 1:
The patent segments drawing information into two distinct types: local drawing information (displayed only on the own terminal) and shared drawing information (displayed on both own and other terminals). This segmentation is achieved by implementing separate processing paths in the delivery managing device - one path handles local drawing information by delivering it only to the own terminal, while another path handles shared drawing information by delivering it to multiple terminals. This resolves the contradiction by maintaining distinguishability through separate handling while enabling both types of drawing information to coexist and improve interactivity.
2Adaptability or versatility
If rich web contents are used to meet various demands, then service functionality is improved, but load on communication terminal becomes heavy
Solution Approach 1:
The patent introduces a delivery managing device as an intermediary between the web content provider and the communication terminal. This intermediary handles the complex processing of rich web contents, including rendering, encoding, and adaptive delivery to multiple terminals. The communication terminal only needs to receive and display the pre-processed video and sound data, significantly reducing its processing load while still benefiting from rich web content functionality.

AI summary
A delivery managing device to which a plurality of terminals are connected through a network includes a creating unit that creates display information based on operation information indicating an operation input accepted by a terminal; a converting unit that converts the display information into video information; and a delivery unit that delivers the video information to a terminal. When non-public operation information is received from a terminal, the non-public operation information indicating operation information not to be published to another terminal, the delivery unit delivers video information that is converted from display information not based on the non-public operation information, to the other terminal.
