Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video coding technologies face challenges in efficiently determining and applying partitioning schemes for video blocks, leading to suboptimal compression and bandwidth utilization, particularly in high-bandwidth digital video applications.
Innovation Solution
A method is introduced to enable or disable partitioning schemes for video blocks based on rules associated with neighboring blocks, considering factors such as block dimensions, position, and coding unit relationships, to optimize coding decisions and bitstream generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If partitioning schemes are applied to all video blocks, then compression efficiency is improved, but computational complexity and processing time increase
Solution Approach 1:
The patent changes the parameter of partitioning scheme application from universal to conditional based on neighboring block analysis. By modifying the condition under which partitioning is applied (using rules about neighboring blocks' partitioning status, block dimensions, and positions), the system achieves better compression efficiency only where needed while reducing overall computational complexity.
2Loss of energy
If partitioning schemes are applied to all video blocks, then bandwidth utilization is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary analysis of neighboring blocks before applying partitioning schemes to current blocks. By pre-determining which blocks should be partitioned based on neighboring block characteristics (coding status, partitioning schemes, positions), the system optimizes bandwidth utilization in advance while minimizing processing time through selective application.
3Speed
If partitioning decisions are made independently for each block, then processing speed is improved, but compression efficiency deteriorates
Solution Approach 1:
The patent introduces feedback mechanisms where partitioning decisions for current blocks are influenced by the coding status and partitioning schemes of neighboring blocks. This feedback loop allows the system to maintain processing speed through localized decisions while improving compression efficiency by considering contextual information from surrounding blocks in the video frame.

AI summary
Systems, methods, apparatus for video processing are described. A video processing method includes determining, for a conversion between a current block of a video and a bitstream of the video, whether or which a partitioning scheme is enabled for coding of the current block according to a rule, and performing the conversion based on the determining. The rule is based on one or more neighboring blocks of the current block.
