Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional video coding methods are used in 5G private networks, then video transmission can be performed, but transmission delay is significant
Solution Approach 1:
The patent applies preliminary action by predicting the signal strength for the next key frame before actual transmission occurs. The encoder uses historical signal strength information to forecast future network conditions, determines the target data volume in advance, and performs intraframe coding accordingly. This allows the key frame to be ready for transmission within one uplink slot without waiting for a complete frame period, thereby reducing transmission delay and improving real-time performance in 5G private networks
2Loss of time
If the target data volume is determined in advance before coding, then transmission can be completed within one uplink slot, but coding flexibility is reduced
Solution Approach 1:
The encoder performs preliminary determination of the target data volume for the next key frame by predicting signal strength based on historical information. This prediction allows the encoder to pre-calculate the appropriate data volume and perform intraframe coding within the constraints of one uplink slot, avoiding the need to wait for a complete frame period and reducing transmission delay
Solution Approach 2:
The patent implements dynamic adaptation by continuously updating the target data volume determination based on predicted signal strength. The encoder dynamically adjusts coding parameters and data volume according to forecasted network conditions, enabling flexible optimization of transmission performance while maintaining the capability to complete key frame transmission within one uplink slot
