Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable broadcast systems face challenges in processing and transmitting 3D video data effectively, leading to potential malfunctions and defective content display when attempting to provide 3D broadcast services, as conventional receivers lack the necessary mechanisms to identify and process 3D video data correctly.
Innovation Solution
A cable broadcast receiver and method that include a receiving unit for processing cable broadcast signals, a control unit to determine the presence of 3D video services by obtaining a 3D service identifier, and a video decoder to extract and decode 3D video data, utilizing system information to identify and process 3D image format information for stereoscopic display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional receivers process 3D video data without proper identification mechanisms, then the broadcast system can transmit 3D content, but the receivers cannot correctly identify and process the 3D video data, leading to malfunctions and defective content display
Solution Approach 1:
The patent applies preliminary action by embedding 3D service identification information and image format information into the broadcast signal before transmission. The receiver then retrieves this pre-prepared information to correctly identify and process 3D video data, avoiding the need for complex real-time analysis and ensuring reliable 3D content display.
2Adaptability or versatility
If the broadcast system provides 3D video services, then users can access 3D content, but the system complexity increases due to the need for additional identification and processing mechanisms
Solution Approach 1:
The patent implements universality by designing a control unit that handles both 2D and 3D video processing through a unified architecture. The same control unit retrieves service identification information, determines service types, and manages video decoding for both 2D and 3D content, eliminating the need for separate dedicated processing paths and reducing overall system complexity.
3Measurement precision
If the receiver obtains and processes 3D service identification information and image format information, then accurate 3D video data processing is achieved, but the processing time and computational resources increase
Solution Approach 1:
The patent applies preliminary action by pre-embedding service identification information and image format information into the broadcast signal during content creation. This allows the receiver to quickly retrieve and process this information without performing complex real-time analysis, significantly reducing processing time while maintaining high accuracy in 3D video data handling.
