Image Transmission Timing Notification for Resolution Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Wi-Fi Direct image transmission, changes in image format, such as resolution, can lead to failure in image reproduction at the receiving end due to delayed recognition and inadequate scaler adjustments.
Innovation Solution
A data transmission device that includes a communication unit transmitting timing information to the receiver about impending changes in image data characteristics, allowing the image reproduction device to pre-configure for format changes, specifically in resolution, frame rate, or compressibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmitting end switches the image format during transmission of image data, then the transmission rate can be dynamically adjusted according to radio conditions, but the receiving end fails to reproduce the image data normally due to delayed recognition and inadequate scaler adjustments
Solution Approach 1:
The transmitting end performs preliminary action by notifying the receiving end of upcoming image format changes in advance. This allows the receiving end to prepare and adjust its scaler settings before the actual format change occurs, ensuring seamless transition and maintaining image reproduction accuracy while enabling dynamic transmission rate adaptation
2Productivity
If the transmitting end changes the resolution of frame images dynamically, then the data volume can be optimized according to radio conditions, but the receiving end cannot recognize the change in time to adjust the scaler setting
Solution Approach 1:
The system implements preliminary notification of resolution changes from the transmitting end to the receiving end. This advance notice enables the receiving end to adjust scaler settings proactively before the resolution change takes effect, eliminating delays and ensuring continuous smooth image reproduction while optimizing data transmission efficiency
Solution Approach 2:
The transmitting end provides feedback information about upcoming resolution changes to the receiving end. This feedback mechanism ensures that the receiving end has real-time awareness of format changes and can synchronize its processing accordingly, preventing any loss of time in scaler adjustment while maintaining optimal data transmission
