Innovation Solution
A receiving system utilizing HDMI digital interface for transmitting and receiving 3D image signals, incorporating a 3D image processor that searches for source devices, processes 3D images, and displays them based on user requests, using Vendor Specific InfoFrame packets to identify 3D formats and control commands via CEC protocol for seamless playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a receiving system manually identifies and processes 3D image signals from multiple source devices, then the system can display 3D images, but the user manipulation and system complexity increase
Solution Approach 1:
The receiving system automatically performs source device identification, 3D image signal detection, and format determination without requiring manual user intervention. The system self-services by autonomously searching for source devices, analyzing Vendor Specific InfoFrame packets, and configuring 3D display parameters, thereby reducing user manipulation while maintaining manageable system complexity through automated workflows
Solution Approach 2:
The receiving system performs preliminary actions by proactively searching for source devices and pre-identifying 3D image signals before user requests. The system automatically analyzes InfoFrame packets in advance to determine 3D formats and configures processing parameters beforehand, eliminating the need for manual user setup and reducing operational complexity
2Extent of automation
If the receiving system automatically searches and processes 3D images from multiple source devices, then user manipulation is reduced, but the processing complexity and time increase
Solution Approach 1:
The automatic processing system is segmented into distinct functional modules: source device search module, InfoFrame packet analysis module, 3D format determination module, and image processing module. Each module handles a specific task independently, reducing overall processing complexity while maintaining high automation. The system divides the complex 3D image playback process into manageable segments that can be executed sequentially
Solution Approach 2:
The Vendor Specific InfoFrame packet serves as an intermediary data structure that carries 3D image signal information from source devices to the receiving system. The system uses this standardized intermediary format to automatically exchange 3D configuration parameters, reducing processing complexity by providing a unified interface for 3D signal identification and format negotiation
3Adaptability or versatility
If the system processes 3D images from multiple source devices with different formats, then versatility is improved, but the difficulty of detecting and measuring 3D formats increases
Solution Approach 1:
The receiving system implements feedback mechanisms by analyzing Vendor Specific InfoFrame packets returned from source devices to automatically determine 3D image formats. The system uses this feedback information to adjust its processing configuration and adapt to different 3D formats (side-by-side, top-bottom, frame sequential), enabling versatile multi-format processing while simplifying format detection through automated feedback loops
Solution Approach 2:
The receiving system employs a universal InfoFrame packet analysis mechanism that can handle multiple 3D image formats through a single standardized interface. The system uses universal packet structures and format identification protocols to detect and process various 3D formats (side-by-side, top-bottom, frame sequential) uniformly, reducing the difficulty of format detection while maintaining broad adaptability
Data Source
AI summary
A three-dimensional (3D) image may be provided in a receiving system by receiving a request for a 3D image viewing while displaying content from a first input source, switching from the first input source to a second input source that correspond to a specific source device, receiving the 3D image transmitted from the specific source device, and displaying the received 3D image at the receiving system.
