Image Processing Device Decoding Failure Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in preventing or reducing decoding errors in referenced frames from affecting subsequent frames, leading to continuous deterioration of image quality.
Innovation Solution
A system comprising a reception device and a transmission device that communicate to identify and manage decoding failures. The reception device decodes frames, identifies decoding failures, and transmits information about affected blocks to the transmission device. The transmission device then processes subsequent frames to avoid referencing the failed blocks, thereby preventing further decoding errors.

Engineering Contradiction Analysis
1Productivity
If compression encoding referencing previous frames is used to increase compression rate, then compression efficiency is improved, but decoding errors propagate to subsequent frames causing continuous deterioration of image quality
Solution Approach 1:
The patent segments the frame data into multiple data packets for transmission. When a decoding error is detected in a specific block of a frame, only the affected data packets are identified and handled separately, rather than affecting the entire frame or subsequent frames. This segmentation allows error isolation and prevents propagation while maintaining overall compression efficiency.
Solution Approach 2:
The patent introduces an intermediary feedback mechanism where the reception device sends error information back to the transmission device. This intermediary communication allows the system to identify decoding errors and take corrective actions (such as requesting retransmission or using alternative reference frames) to prevent error propagation, thus maintaining image quality stability while preserving compression benefits.
2Reliability
If error prevention mechanisms are implemented to stop decoding error propagation, then image quality stability is improved, but system complexity increases due to additional error detection and communication protocols
Solution Approach 1:
The patent implements partial error detection by focusing only on specific blocks within frames where decoding errors occur, rather than performing comprehensive error checking on entire frames. This selective approach reduces the complexity of error detection mechanisms while still effectively preventing error propagation to subsequent frames, maintaining a balance between reliability and system complexity.

AI summary
The disclosure relates to a reception device of an image processing system. The reception device is configured to receive, from a transmission device, at least one data packet including data of a first frame, perform decoding on the first frame based on the at least one data packet, identify whether a failure in decoding on the first frame occurs, and based on identifying that the failure in decoding on the first frame occurs, transmit, to the transmission device, first information related to at least one first block where the decoding failure occurs. The first information may include block ID information about the at least one first block where the decoding failure occurs and frame ID information about the first frame to which the at least one first block belongs.
