Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network operators face challenges in efficiently utilizing their limited radio resources to provide 3D video services due to the increased capacity requirements, which are difficult to enhance given the limited spectrum bandwidth and cost constraints.
Innovation Solution
A communication system that includes a source multimedia device capable of receiving multiview video data, generating spatial disparity information, determining the 3D video content quality level capability of the destination device, and encoding the video data accordingly to optimize transmission based on the selected quality level or user-selected service category, thereby conserving bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D video transmission uses at least twice the bandwidth of single view transmission, then 3D video quality is improved, but radio resource consumption increases
Solution Approach 1:
The system dynamically adjusts the quality level parameter of 3D video content based on the capabilities of the destination device. By changing the quality parameter from high to low or medium based on device capabilities, the system reduces radio resource consumption while maintaining acceptable video quality for the target device.
Solution Approach 2:
Instead of always transmitting at maximum quality (excessive action), the system transmits at the appropriate quality level for the destination device (partial action). This avoids wasting radio resources on high-quality transmission when the destination device cannot utilize it, while still providing sufficient quality when needed.
2Adaptability or versatility
If multiple view coding uses eight cameras or more, then 3D video coverage is improved, but capacity requirements increase
Solution Approach 1:
The system changes the quality level parameter based on destination device capabilities. When transmitting multiview video data from multiple cameras, the system adjusts the quality parameter to match what the destination device can handle, thereby reducing capacity requirements while maintaining adequate 3D video coverage.
Solution Approach 2:
The system dynamically adapts the transmission parameters based on the destination device's capabilities rather than using fixed high-quality transmission. This dynamic adjustment allows the system to optimize capacity usage while maintaining versatile 3D video coverage capabilities.
3Reliability
If wireless network operators enhance radio capacity, then 3D service quality is improved, but spectrum bandwidth and cost increase
Solution Approach 1:
The system changes the quality level parameter dynamically based on destination device capabilities. By adjusting this parameter, the system optimizes the use of existing radio resources without requiring operators to enhance capacity through additional spectrum bandwidth or infrastructure upgrades.
Solution Approach 2:
The system enables self-optimization by automatically adapting transmission parameters based on destination device capabilities. This self-service approach allows efficient use of existing radio resources without requiring operator intervention to enhance capacity or increase spectrum bandwidth.

AI summary
A communication system is provided that includes a source multimedia communication device that supports three dimension (3D) video streaming to a destination multimedia communication device. The source multimedia communication device receives multiview video data from multiple multiview video data sources, generates spatial disparity information based on the multiview video data, determine a 3D video content quality level capability of the destination multimedia communication device or user selected service category (low 3D scene or high 3D scene), select a 3D video content quality level for the video data based on the determined 3D video content quality level capability or user selected service category, and encodes the multiview video data based on the selected 3D video content quality level or user selected service category to produce encoded video data for conveyance to the destination multimedia communication device.
