Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution and high-quality image data is transmitted or stored using conventional methods, then image quality is maintained, but transmission and storage costs increase due to higher data volumes
Solution Approach 1:
The current picture is divided into multiple slices, with each slice containing one or more tiles. This hierarchical segmentation allows for more efficient encoding and processing of high-resolution images, reducing the overall data volume while maintaining image quality through targeted compression strategies applied to each segment
2Productivity
If a current picture is partitioned into multiple slices and tiles with detailed encoding information, then compression efficiency is improved, but device complexity increases
Solution Approach 1:
The picture is divided into slices containing tiles, creating a hierarchical structure that improves compression efficiency by allowing independent processing and optimization of each segment while maintaining manageable complexity through organized segmentation
Solution Approach 2:
The patent introduces a hierarchical dimension to picture organization by dividing the picture into slices, which contain tiles, which in turn contain bricks. This multi-level hierarchical structure enables more efficient compression by applying different encoding strategies at each level, improving productivity while managing complexity through structured organization

AI summary
Disclosed herein are a video encoding/decoding method and apparatus. The video decoding method according to the present disclosure includes: when a current picture is composed of a plurality of tiles and a current tile among the plurality of tiles is partitioned into a plurality of slices, decoding information on the number of slices in tile that indicates the number of the plurality of slices comprised in the current tile; decoding information on a slice height in tile that indicates a height of the plurality of slices comprised in the current tile; and determining the number of the plurality of slices comprised in the current tile and a height of the plurality of slices comprised in the current tile.
