Advance Download Control for Video Conference Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face issues with video conference quality degradation and disconnection due to insufficient bandwidth during advance data downloads, as users are unaware of the bandwidth requirements for video conferencing.
Innovation Solution
A communication system with a receiving unit for metadata, a determination unit to assess if update data is eligible for advance download, and a control unit to manage timing for advance downloads, ensuring that bandwidth is secured before starting a video conference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If advance download of update data is performed, then download requests are distributed and updates can be advanced smoothly, but bandwidth necessary for video conference cannot be secured causing quality degradation or disconnection
Solution Approach 1:
The system dynamically adjusts the download timing of update data based on the operational state of the terminal apparatus. When the terminal is in a state suitable for updates (e.g., not currently conducting video conferences), the system performs advance downloads. When video conference operations are detected, the system suspends or prioritizes conference traffic over update downloads, thereby adapting network resource allocation to current operational needs and preventing quality degradation.
Solution Approach 2:
The system performs preliminary determination of download timing by checking whether the terminal apparatus is in an appropriate state before initiating advance downloads. This preliminary check ensures that update downloads only commence when they will not interfere with critical operations like video conferences, thus maintaining both update progress and conference quality.
2Productivity
If advance download is performed without checking terminal state, then download can be executed early, but user is unconscious of bandwidth requirements causing unintended quality degradation
Solution Approach 1:
The system incorporates feedback mechanisms that monitor the terminal's operational state and network conditions in real-time. Based on this feedback, the system intelligently determines whether to proceed with advance downloads or postpone them until appropriate conditions are met. This feedback loop ensures that downloads are performed efficiently while maintaining user awareness of system state and preventing unintended quality issues.
Solution Approach 2:
The terminal apparatus autonomously determines its own suitability for receiving update downloads by self-monitoring its operational state. The system automatically adjusts its download behavior based on internal state assessment without requiring explicit user intervention, thereby maintaining both productivity and ease of operation.
3Reliability
If update data is downloaded before update start date, then concentration of download requests is prevented, but bandwidth for video conference cannot be secured
Solution Approach 1:
The system dynamically controls the timing and rate of update data downloads based on real-time assessment of network bandwidth availability and terminal operational state. When bandwidth is sufficient and the terminal is in an appropriate state, the system proceeds with advance downloads to prevent request concentration. When bandwidth constraints are detected or the terminal is engaged in critical operations, the system automatically adjusts or suspends downloads, thereby maintaining both download stability and adequate bandwidth for video conferences.

AI summary
A disclosed communication apparatus includes a receiving unit that receives metadata of update data used for an update; a determination unit that determines, based on a description of the metadata, whether or not there is update data that is subject to advance download in which download of the update data is executed before a point of time at which the update is able to start; a control unit that determines whether or not it is timing to perform the advance download; and an update processing unit that downloads the update data in a case in which the determination unit determines that there is the update data that is subject to the advance download and the control unit determines that it is the timing to perform the advance download.
