Digital Broadcast Frame Generation with Appended Signal Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frame generation methods for digital broadcast waves lack efficiency in transmitting and processing received information, leading to inconsistencies and difficulties in real-time data obtainment for later-stage devices.
Innovation Solution
A frame generation method and device that demodulate digital broadcast signals, generate packets with content information, and append additional received information, such as signal quality and error ratios, to create transmission frames, enabling real-time obtainment and accurate processing by later-stage devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If received information is transmitted separately from content packets, then information completeness is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent combines received information and content packets into a single integrated transmission frame structure. The frame includes both the content packet and appended received information (such as signal quality, error ratios, and demodulation status) together, eliminating the need for separate transmission channels and improving overall transmission efficiency while maintaining information completeness.
2Loss of time
If received information is appended to transmission frames, then real-time obtainment is improved, but frame complexity increases
Solution Approach 1:
The received information is appended to the transmission frame during the frame generation process itself, before transmission occurs. This preliminary inclusion of metadata (signal quality, error ratios, demodulation status) alongside content packets enables receiving devices to obtain all necessary information in real-time without requiring additional processing steps or separate information retrieval operations.
3Measurement precision
If multiple types of received information are included, then data accuracy is improved, but processing difficulty increases
Solution Approach 1:
The transmission frame structure is segmented into distinct functional regions: a content packet area for actual data and an appended information area for metadata. The appended information is further organized into specific fields such as signal quality indicators, error ratios, and demodulation status. This segmentation allows receiving devices to efficiently process different types of information separately while maintaining overall data accuracy.

AI summary
A frame generation method includes: demodulating a digital broadcast signal that is based on a received digital broadcast wave; generating a packet including content information obtained in the demodulating; and generating a transmission frame including appended information and the packet. The appended information includes received information that is obtained in the demodulating. The received information is information other than the content information.
