Communication Terminal Resolution Data Exchange for Videoconference Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In videoconference systems, transmitting high-resolution data from external input apparatuses to communication terminals leads to increased workload and potential delays due to the need for data conversion, as these terminals often receive unnecessary high-resolution data.
Innovation Solution
The communication terminal sends resolution data to the external apparatus, which determines and converts the display data to a suitable lower resolution for transmission, reducing the data size and processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution data is transmitted from external input apparatus to communication terminal, then display quality is improved, but communication time increases and terminal workload increases
Solution Approach 1:
The external input apparatus changes the resolution parameter of display data based on received resolution information, transmitting data at an appropriate resolution rather than always using maximum resolution, thus reducing communication time while maintaining adequate display quality
Solution Approach 2:
The communication terminal sends resolution information to the external input apparatus in advance before receiving display data, allowing the external apparatus to prepare and transmit data at the correct resolution from the start, avoiding subsequent conversion delays
2Manufacturing precision
If high-resolution data is transmitted from external input apparatus to communication terminal, then display quality is improved, but terminal processing workload increases
Solution Approach 1:
The external input apparatus adjusts the resolution parameter of display data according to the terminal's capabilities, ensuring data is transmitted at an appropriate resolution that matches the terminal's display resolution, thereby reducing the terminal's conversion workload
3Manufacturing precision
If high-resolution data is transmitted from external input apparatus to communication terminal, then display quality is improved, but data size increases causing unnecessary delay
Solution Approach 1:
The external input apparatus changes the resolution parameter of display data based on received resolution information, transmitting data at an appropriate resolution that matches the terminal's display capabilities, thus reducing data size and communication delay while maintaining adequate display quality

AI summary
In a communication system, a communication terminal displays an image based on display data being displayed and sent by an external apparatus. The communication terminal sends first resolution data specifying a resolution of a display of the communication terminal to the external apparatus. The external apparatus determines a resolution of the display data to be transmitted, based on the first resolution data, and second resolution data specifying a resolution of a display of the external input apparatus. The external apparatus sends the display data, which is converted to have the determined resolution, to the communication terminal.
