Signal Processing Device Bootstrap Decoding Pipeline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal processing devices for terrestrial digital broadcasting and mobile communication signals face inefficiencies in processing frame data, leading to prolonged data output times due to the sequential decoding of bootstrap, basic signaling, and payload data within specific frame periods.
Innovation Solution
A signal processing device equipped with a synchronizer to decode bootstrap data and an error corrector with a decoder to process basic signaling data within the first frame data period, allowing for the initiation of payload data processing within the same period, and an equalizer to reconfigure preambles based on decoded signaling data, thereby shortening data output times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If basic signaling data decoding is completed only after bootstrap data decoding, then decoding accuracy is ensured, but data output time is prolonged
Solution Approach 1:
The patent applies preliminary action by performing bootstrap data decoding in advance during the first frame data period, before payload data processing begins. The synchronizer decodes bootstrap data and provides decoded results to the decoder, enabling basic signaling data decoding to start immediately without waiting for complete bootstrap decoding. This preliminary preparation reduces the overall data output time while maintaining decoding accuracy through proper sequencing.
2Productivity
If payload data processing starts after complete decoding of first frame data, then data integrity is ensured, but processing efficiency is reduced
Solution Approach 1:
The patent segments the decoding process into distinct phases: bootstrap data decoding by the synchronizer, basic signaling data decoding by the decoder, and payload data processing. This segmentation allows each component to operate independently at optimized times - the synchronizer processes bootstrap data during the first frame period while the decoder simultaneously prepares to process basic signaling data, enabling payload processing to start within the same frame period without compromising data integrity through proper phase separation.
Solution Approach 2:
The synchronizer performs preliminary decoding of bootstrap data and provides results to the decoder in advance, enabling the decoder to begin basic signaling data decoding before the first frame data period ends. This preliminary action creates a pipeline effect where payload data processing can be initiated within the first frame period, improving processing efficiency while maintaining reliability through staged validation.
3Loss of time
If sequential decoding of bootstrap, basic signaling, and payload data is used, then decoding accuracy is maintained, but data output time is extended
Solution Approach 1:
The patent implements continuity of useful action by establishing a continuous decoding pipeline where the synchronizer continuously decodes bootstrap data and feeds results to the decoder, which continuously decodes basic signaling data and enables payload processing. This continuous flow eliminates idle waiting periods between decoding stages, reducing data output time while maintaining decoding accuracy through uninterrupted processing and proper data validation at each stage.
