Reference Picture List Generation for Video Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video compression techniques face challenges in efficiently encoding and decoding high-resolution, high-quality video signals, particularly in handling three-dimensional (3D) video content, due to increased data size and transmission/storage costs.
Innovation Solution
A method and apparatus for generating a reference picture list based on a current picture reference flag, obtaining motion information, and restoring blocks using this information for efficient prediction and encoding/decoding, which includes arranging temporal reference pictures and determining the use of a current picture reference mode based on flags, indices, and partition modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video data is transmitted or stored using existing media and methods, then high-resolution and high-quality video content can be provided, but transmission cost and storage cost increase
Solution Approach 1:
The patent extracts and utilizes only the necessary reference information from pictures by introducing reference picture lists with selective picture ordering and reference indices. This allows the system to take out only the essential data needed for prediction, reducing transmission and storage costs while maintaining high video quality through efficient inter-picture and intra-picture prediction methods.
2Manufacturing precision
If video resolution and quality are increased, then high-definition and ultra-high-definition video content is achieved, but data amount increases
Solution Approach 1:
The patent changes the parameter of reference picture selection by introducing reference picture lists that allow selective ordering and indexing of reference pictures. This enables the system to adaptively choose the most relevant reference pictures for prediction, thereby maintaining high video resolution while reducing the amount of data that needs to be transmitted and stored through more efficient compression.
3Productivity
If existing video compression techniques are used, then some compression is achieved, but efficiency in encoding and decoding high-resolution 3D video content is insufficient
Solution Approach 1:
The patent introduces dynamic reference picture lists that can be adaptively configured based on the specific video content and prediction requirements. The reference picture lists allow the system to dynamically select and order reference pictures, enabling more efficient encoding and decoding of high-resolution 3D video content while maintaining high video quality through adaptive prediction strategies.
