Turbo Stream Frame Access for Fast Mobile Broadcasting Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Advanced Television Systems Committee (ATSC) standard for digital television broadcasting is inefficient for mobile applications due to its inability to effectively receive radio waves while terminals are moving, and existing technologies struggle to provide fast access to broadcasting services as user demands increase.
Innovation Solution
A method and apparatus for transmitting and receiving broadcasting services using packetized data to generate turbo streams, which include a primary service and access information, allowing for efficient use of frequency bands by including access information in a predetermined region of transmission frames, such as the data field sync segment, and transmitting signaling information through remaining data regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If access information is placed in a predetermined region of transmission frames, then access speed to broadcasting service is improved, but transmission frame structure complexity increases
Solution Approach 1:
Access information is placed in a predetermined region (such as the data field sync segment) of the transmission frame before the actual data transmission. This preliminary placement allows receiving terminals to quickly locate and access required information without searching through the entire frame, thereby improving access speed while the structured placement minimizes the increase in frame structure complexity.
2Productivity
If signaling information is transmitted through remaining data regions, then bandwidth utilization is improved, but signal processing complexity increases
Solution Approach 1:
The transmission frame is segmented into different regions with specific functions: a predetermined region for access information and remaining data regions for signaling information. This segmentation allows efficient bandwidth utilization by filling all available spaces, while the clear regional division simplifies signal processing by enabling receivers to systematically extract information from specific regions rather than processing the entire frame uniformly.
3Productivity
If turbo streams are mapped to transmission frames with remaining data regions, then transmission efficiency is improved, but reception processing time increases
Solution Approach 1:
Access information required for turbo stream retrieval is placed in the predetermined region of the transmission frame before the turbo streams themselves. This preliminary placement enables receiving terminals to quickly obtain access information and directly locate turbo streams in remaining data regions without waiting to process the entire frame, thereby improving transmission efficiency while minimizing additional reception processing time.
