3D Content Encoding Dependency Management for Flexible Screen Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for transmitting three-dimensional (3D) content, such as those based on the MPEG DASH standard, face challenges in providing flexible screen formations and efficient adaptation to varying environments, particularly in supporting high-efficiency video coding (HEVC) and 3DV formats.
Innovation Solution
A method and apparatus for encoding 3D content by setting dependencies between texture and depth information, generating bitstreams that include these dependencies, and integrating identifier and dependency parameters into the MPEG DASH standard, allowing for flexible screen formations and compatibility with existing technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current MPEG DASH standard is used for transmitting 3D content, then compatibility with existing technologies is maintained, but flexible screen formation and efficient adaptation to varying environments are limited
Solution Approach 1:
The patent segments 3D content into separate depth information and texture information streams, allowing independent encoding and transmission. This segmentation enables flexible recombination at the receiver端 to form different screen configurations (2D, 3D, multi-view) without requiring complex pre-encoding for all possible scenarios, thus improving adaptability while managing encoding complexity.
Solution Approach 2:
The patent introduces dynamic dependency parameters that allow the encoding structure to adapt to varying transmission environments and client capabilities. The dependency relationships between depth and texture information can be dynamically adjusted based on network conditions and device requirements, enabling efficient adaptation without fixed complex structures.
2Adaptability or versatility
If separate depth information and texture information are used, then flexibility in screen formation is improved, but the complexity of setting relationships and dependencies increases
Solution Approach 1:
The patent establishes predefined dependency relationships between depth information and texture information during the encoding phase. These preliminary settings include default dependency parameters that define how depth and texture streams relate to each other, reducing the complexity of runtime decision-making while maintaining flexibility for different screen formations.
Solution Approach 2:
The patent introduces dependency parameters as intermediary elements that mediate between separate depth and texture information streams. These parameters act as a bridge, defining the relationships without requiring complex direct interactions between the separate information types, thus simplifying the overall system complexity while maintaining flexibility.
3Adaptability or versatility
If dependency parameters are added to MPEG DASH standard, then compatibility with existing technology is maintained while supporting new 3D formats, but the complexity of the encoding standard increases
Solution Approach 1:
The patent designs dependency parameters with universal applicability that can work across multiple 3D formats (MVC, SVC, HEVC, 3DV) and different screen formations (2D, 3D, multi-view). This multi-functional design allows a single parameter structure to serve multiple purposes and formats, reducing the need for format-specific complex structures while maintaining broad compatibility and support.
