Solution Approach 2:
The patent extracts and utilizes predictive information from surrounding blocks to infer pixel values, reducing the amount of data that needs to be transmitted while preserving image quality through intelligent data selection and compression
2Manufacturing precision
If high-resolution and high-quality video data is stored using existing storage media, then video quality is improved, but storage costs increase
Solution Approach 1:
The patent changes the storage parameter by implementing efficient compression algorithms that reduce the bit depth and data volume required for video storage while maintaining high quality through advanced prediction and coding techniques
Solution Approach 2:
The patent segments video data into blocks and applies prediction techniques to each block independently, allowing for efficient compression and storage while preserving overall video quality through systematic data organization
3Measurement precision
If intra prediction mode information is coded using traditional methods, then coding accuracy is maintained, but signaling overhead increases
Solution Approach 1:
The patent changes the coding parameter by applying truncated binary code to represent intra prediction mode information, reducing the number of bits required for signaling while maintaining prediction accuracy through optimized code length selection
Solution Approach 2:
The patent uses partial action by applying truncated binary code that may not always provide the most precise representation but suffices for the application requirements, reducing signaling overhead while maintaining adequate prediction mode accuracy
