Communication Terminal Frame Rate Adjustment for Video Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing frame rates of moving images during video conferencing, leading to potential overload and errors when establishing communication between multiple terminals.
Innovation Solution
The communication terminal reduces the frame rate of moving images after receiving a video-conference start notice, adjusting the frame rate based on the device model to optimize performance and prevent overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the frame rate of moving images is maintained at a high level during video conferencing, then the image quality is improved, but the load on the terminal increases leading to errors and instability
Solution Approach 1:
The patent applies dynamics by making the frame rate adjustable rather than fixed. The terminal dynamically changes the frame rate based on communication status - maintaining high frame rates for image quality when communication is stable, and reducing frame rates when communication begins to prevent terminal overload and errors. This dynamic adjustment resolves the contradiction between image quality and terminal stability.
Solution Approach 2:
The patent changes the frame rate parameter according to communication conditions. When a video conference start notice is received or communication status changes, the terminal modifies the frame rate parameter of moving images to balance image quality requirements with terminal load capacity, preventing errors while maintaining acceptable image quality.
2Reliability
If the frame rate of moving images is reduced to prevent terminal overload, then the terminal stability is improved, but the image quality deteriorates
Solution Approach 1:
The system dynamically adjusts frame rate based on real-time communication status rather than using a fixed low frame rate. When communication is stable, higher frame rates are used for better image quality. When communication changes or load increases, the frame rate is reduced to maintain terminal stability. This dynamic approach prevents terminal overload while minimizing image quality deterioration.
Solution Approach 2:
The terminal performs preliminary actions by detecting communication status changes (such as receiving a video conference start notice) and proactively adjusting the frame rate before terminal overload occurs. This preventive adjustment maintains terminal stability while preserving image quality as much as possible by only reducing frame rate when necessary.
3Adaptability or versatility
If multiple applications with various functions are executed in the same communication terminal, then the versatility is improved, but the device complexity increases leading to potential overload
Solution Approach 1:
The patent applies partial action by selectively adjusting the frame rate of moving images based on communication needs. When multiple applications are running and terminal load increases, the system partially reduces the frame rate rather than shutting down functions. This allows the terminal to maintain multiple communication functions and versatility while managing complexity and preventing overload through controlled reduction of non-critical parameters.

AI summary
A communication terminal comprising circuitry, a method of outputting moving images, and a computer-readable non-transitory recording medium storing a program for causing a computer to execute the method. The communication terminal and the method includes receiving an event related to an initiation of communication with a counterpart communication terminal, inputting moving images output by an external device, and outputting the moving images input by the inputting to a display. After the receiving receives the event related to the initiation of communication, the outputting includes reducing a frame rate of the moving images to be output to the display.
