3D Video Format Adaptation for Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a unified standard for 3D video formats and display capabilities leads to compatibility issues between playback devices and display devices, limiting market acceptance of 3D technology.
Innovation Solution
A method where the playback device determines and adapts the 3D video format to match the display device's capabilities by querying the display device's supported formats and selecting the best matching format for transmission, ensuring compatibility without exceeding existing interface limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If 3D video content is transmitted using existing interface standards, then transmission compatibility is maintained, but the bandwidth is insufficient to handle the higher data requirements of 3D video
Solution Approach 1:
The system dynamically adjusts the 3D video transmission format based on the display device's capabilities. The playback device queries the display device to determine supported formats and automatically selects the appropriate transmission method, enabling adaptive bandwidth utilization without compromising interface compatibility
Solution Approach 2:
The patent changes transmission parameters by converting 3D video content between different formats (side-by-side, top-and-bottom, frame packing) and encoding methods (H.264, VC-1) to match the display device's capabilities, thereby optimizing bandwidth utilization while maintaining compatibility with existing interface standards
2Adaptability or versatility
If multiple 3D video formats are supported to accommodate different display devices, then compatibility improves, but system complexity increases
Solution Approach 1:
The playback device performs self-service by automatically querying the display device's capabilities and selecting the appropriate 3D video format without user intervention. This automation reduces the perceived complexity for users while maintaining support for multiple formats
Solution Approach 2:
The system implements feedback mechanisms where the playback device queries the display device to receive information about supported 3D formats and capabilities, then uses this feedback to automatically configure the optimal transmission format, simplifying the overall system operation
3Productivity
If 3D video transmission methods are customized for specific display types, then transmission efficiency improves, but versatility across different display devices decreases
Solution Approach 1:
The playback device is designed with multi-functionality to support multiple 3D video formats and transmission methods simultaneously. It can adaptively select from side-by-side, top-and-bottom, frame packing, and other formats based on the display device's capabilities, achieving both transmission efficiency and broad versatility
Solution Approach 2:
The system dynamically adjusts the transmission method based on real-time detection of display device capabilities, transforming from a static one-to-one mapping approach to a dynamic many-to-many relationship that optimizes transmission efficiency for each specific display while maintaining universal compatibility

AI summary
A method of transmitting three dimensional video information over an interface from a playback device to a displaying device, the displaying device and the interface such that the properties of the displaying device can be queried over the interface, the method comprising determining one or more video format in which a compressed three dimensional video information is available to an input of the playback device, the three dimensional video information available either as stored on a record medium or received via a data transmission system; querying the displaying device over the interface with respect to one or more three dimensional video formats which the displaying device is able to process; selecting a best matching video format, wherein the best matching video format different from at least one available video format, the selection of the best matching video format based on the available video format and the video formats which the displaying device is able to process; processing the compressed three dimensional video information such that the three dimensional video information is transmitted over the interface in the best matching video format.
