Communication Terminal Bandwidth Reduction via Sensor Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video communications require large bandwidth, leading to increased costs and reduced quality during high traffic times, as existing systems reserve excessive bandwidth even when it's not needed, and continue transmitting unnecessary video data.
Innovation Solution
A communication system that allows for real-time reduction of bandwidth by determining when video data is no longer needed and sending a message to stop its transmission, switching to audio-only mode, and resuming video transmission as necessary, using sensors and user input to manage bandwidth allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted during a communication session, then communication quality is improved, but bandwidth consumption increases
Solution Approach 1:
The system dynamically adjusts the communication mode between video and audio-only based on real-time conditions. The terminal determines whether video data is needed and sends corresponding messages to switch between transmission modes, making the bandwidth allocation flexible rather than static throughout the communication session.
Solution Approach 2:
The system changes the transmission parameter from video data to audio-only data based on determined conditions. When video is no longer needed, the terminal sends a message to stop video transmission, effectively changing the data type parameter being transmitted to reduce bandwidth consumption.
2Reliability
If bandwidth is reserved for video communication, then communication reliability is improved, but available bandwidth for other users decreases
Solution Approach 1:
The bandwidth reservation is made dynamic by allowing real-time switching between video and audio-only modes. When video transmission is stopped, the previously reserved bandwidth becomes available for other users, thus dynamically adjusting bandwidth allocation based on actual communication needs.
3Reliability
If video transmission continues during communication, then communication completeness is maintained, but unnecessary bandwidth is consumed
Solution Approach 1:
The terminal actively monitors communication conditions and provides feedback by determining when video data is no longer needed. Based on this determination, it sends messages to switch to audio-only mode, creating a feedback loop that adjusts bandwidth consumption according to actual communication requirements.
Solution Approach 2:
The system extracts the video component from the communication session when it is no longer needed, separating it from the essential audio communication. This allows the system to maintain complete audio communication while removing the unnecessary video data transmission that consumes bandwidth.

AI summary
A communication system, method and communication terminal are configured to permit bandwidth reduction when communication partners are engaged in a communication session. In one embodiment, a communication terminal such as a cellular phone or tablet may turn off at least one of its display and camera sensor within a predetermined amount of time when the terminal is detected as being positioned near a user's ear via at least one sensor of the terminal. In some embodiments, the communication terminal may also transmit one or more messages to communication devices of communication partners engaged in the communication session to inform those devices that video transmissions should no longer be sent to the communication terminal. The communication terminal and other communication devices involved in the communication session may also stop transmitting video as a result of the detection of the communication terminal being positioned near a user's ear.
