Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution and high-quality images are transmitted or stored, then image quality is improved, but transmission costs and storage costs increase
Solution Approach 1:
The image is divided into multiple blocks that are processed independently through inter prediction and intra prediction methods. Each block is encoded separately, allowing for efficient compression while maintaining overall image quality. The segmentation enables selective application of different prediction modes to different regions of the image.
Solution Approach 2:
The patent employs multiple prediction modes (inter prediction with various motion compensation methods, intra prediction with different directional modes) that change the parameters of how pixel values are predicted. By adjusting prediction parameters such as motion vectors, reference block selections, and prediction directions, the system achieves better compression efficiency while preserving image quality.
2Loss of energy
If inter prediction and intra prediction methods are used to improve compression efficiency, then information transfer costs are reduced, but processing complexity increases
Solution Approach 1:
The patent dynamically selects between inter prediction and intra prediction modes based on the characteristics of each block. The prediction mode selection is adaptive, choosing the most suitable method for each specific block to optimize compression while managing processing complexity. This dynamic approach allows the system to respond to local image characteristics rather than applying a uniform method throughout.
Solution Approach 2:
The prediction methods utilize self-referencing techniques where blocks predict their own values based on neighboring blocks or previously decoded information. Intra prediction uses adjacent pixels within the same picture, while inter prediction uses previously decoded frames, allowing the system to serve itself without external assistance and reducing overall processing requirements.
3Manufacturing precision
If multiple prediction modes are implemented to maintain image quality during compression, then compression efficiency is improved, but the amount of processed information increases
Solution Approach 1:
The patent performs prediction operations before final encoding, using preliminary prediction blocks to estimate pixel values. Motion compensation and various prediction modes are applied in advance to generate prediction blocks that closely match the original blocks, reducing the residual information that needs to be encoded and transmitted. This preliminary action significantly reduces the amount of information that requires further processing.
Solution Approach 2:
Prediction blocks serve as intermediaries between the original image blocks and the final encoded representation. These intermediate prediction blocks facilitate the compression process by providing a basis for calculating residuals, which are then encoded. The intermediary prediction structures enable efficient information reduction while maintaining the ability to reconstruct high-quality images.

AI summary
The present disclosure relates to a technique for encoding and decoding video data, and more particularly, to a method for performing inter-prediction in an effective manner. The present disclosure combines an inter-prediction method using an AMVP mode and an inter-prediction method using a merge mode so as to propose a method for using the same candidate. The method for encoding video data proposed by the present disclosure comprises the following steps: receiving mode information on an inter-prediction method of a current block; determining, on the basis of the received mode information, whether the interprediction method to be applied to the current block is an AMVP mode or a merge mode; and selecting a candidate to derive motion information of the current block, wherein the candidate is selected in a left region, top region and corner region of the current block and in the same position block as the current block, and the AMVP mode and the merge mode are applied on the basis of the selected candidate.
