Adaptive Image Frame Error Correction via Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods waste channel bandwidth by periodically transmitting intra-frame encoding data even when image frames are received correctly, leading to inefficient channel utilization and potential errors due to data transmission errors.
Innovation Solution
An image processing method where a receiving terminal detects reception errors and sends feedback messages to the transmitting terminal, allowing the use of error correction mechanisms to encode and retransmit only necessary data, optimizing the transmission of intra-frame and inter-frame encoding data based on reception states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intra-frame encoding data is periodically transmitted to correct transmission errors, then reliability of image frame reception is improved, but channel bandwidth is wasted and channel utilization deteriorates
Solution Approach 1:
The receiving terminal sends feedback information to the transmitting terminal indicating whether each image frame was received correctly. Based on this feedback, the transmitting terminal selectively retransmits only the frames that were received incorrectly, rather than periodically transmitting all intra-frame encoding data. This feedback mechanism resolves the contradiction by making the transmission adaptive to actual reception conditions, improving reliability only when necessary and avoiding unnecessary bandwidth consumption.
Solution Approach 2:
The transmission strategy dynamically adjusts based on reception conditions. Instead of using a fixed periodic transmission schedule, the system changes its behavior according to feedback from the receiving terminal. When frames are received correctly, no retransmission occurs; when errors occur, selective retransmission is triggered. This dynamic adaptation resolves the contradiction between maintaining reliability and optimizing channel utilization.
2Reliability
If intra-frame encoding data is transmitted periodically for error correction, then data transmission reliability is improved, but transmission efficiency deteriorates due to unnecessary transmissions
Solution Approach 1:
The system uses feedback information from the receiving terminal to determine whether retransmission is necessary. The feedback indicates which specific image frames were received incorrectly, allowing the transmitting terminal to selectively retransmit only those frames. This approach maintains data transmission reliability while improving transmission efficiency by eliminating unnecessary periodic transmissions of correctly received data.
Solution Approach 2:
The system extracts and identifies only the specific image frames that contain transmission errors based on feedback information. Instead of retransmitting all intra-frame encoding data periodically, only the erroneous frames are selected and retransmitted. This extraction approach resolves the contradiction by separating the necessary error correction transmissions from the unnecessary periodic transmissions, thereby maintaining reliability while improving transmission efficiency.

AI summary
An image processing method includes a transmitting terminal receiving a feedback message sent by a receiving terminal. The feedback message indicates a reception state of a received image frame sent by the transmitting terminal and received by the receiving terminal before the receiving terminal sends the feedback message. The method further includes acquiring a target image frame, encoding the target image frame according to a preset error correction mechanism to generate encoding data of the target image frame in response to the feedback message indicating a reception error, and sending the encoding data of the target image frame to the receiving terminal.
