Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video processing systems are limited in converting and displaying 2-D, 3-D, and multi-view content optimally across different display devices and formats, leading to a difficult user experience due to the lack of mechanisms to analyze content, display type, and mode for optimal viewing.
Innovation Solution
A system and method that receive a video signal, determine its format and the display device's capabilities, and convert the signal into an intermediate format before optimizing it for display, using an input stream processor, controller, and video signal processor circuit to ensure seamless playback on various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video processing systems use multiple conversion mechanisms for different display formats, then compatibility with diverse display devices is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediate video format as a mediator between various input video formats and different display device requirements. The conversion system first converts diverse input formats (2-D, 3-D, multi-view) into this standardized intermediate format, which then serves as a common basis for subsequent conversion to any target display format. This intermediary approach simplifies the overall conversion architecture by breaking down complex direct conversions into manageable two-stage processes.
Solution Approach 2:
The video format conversion process is segmented into distinct functional stages: input format detection, conversion to intermediate format, and conversion to target display format. Each stage is handled by separate processing modules that can independently analyze and transform video data according to specific requirements. This segmentation allows the system to manage complexity by dividing the conversion task into smaller, more manageable operations.
2Manufacturing precision
If the system performs comprehensive analysis of content and display parameters, then optimal display quality is achieved, but processing time increases
Solution Approach 1:
The system performs preliminary detection and analysis of video signal parameters (such as format type, resolution, and 3-D characteristics) as soon as the video signal is received, before actual conversion operations begin. This preliminary action includes identifying the input format and determining appropriate conversion parameters in advance, so that when conversion is needed, the system already has the information required to execute it efficiently without delays caused by real-time analysis during playback.
3Adaptability or versatility
If the system converts all video signals through an intermediate format, then format compatibility is improved, but conversion processing complexity increases
Solution Approach 1:
The intermediate video format serves as a universal intermediary that can receive and convert from multiple different input formats (2-D, 3-D, multi-view) and output to various display device requirements. This multi-functional intermediate format acts as a common language that enables the system to handle diverse format conversions through a standardized process, improving format compatibility while maintaining manageable conversion complexity.
