Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital radio broadcast signals are prone to intermittent fades or blockages, leading to signal quality issues and gaps in reception due to errors in the data transmission, which disrupt the uninterrupted rendering of content at digital radio broadcast receivers.
Innovation Solution
A computer-implemented method and system that processes digital radio broadcast signals to identify data errors, transmitting notifications to enable duplicate data to be received via alternative wireless communication, ensuring corrected data is processed for uninterrupted content rendering, utilizing a non-transitory computer-readable storage medium with instructions to execute these steps.

Engineering Contradiction Analysis
1Area of stationary object
If digital radio broadcast signals are transmitted via traditional broadcast transmission, then the service coverage is extensive, but signal quality deteriorates due to intermittent fades or blockages
Solution Approach 1:
The patent introduces a dual transmission path system where data is transmitted through both traditional broadcast transmission and wireless internet transmission. The wireless internet acts as an intermediary alternative path that bypasses the fade or blockage issues affecting traditional broadcast signals, thereby maintaining signal quality while preserving extensive service coverage.
Solution Approach 2:
The system dynamically changes the transmission parameter by switching between broadcast transmission and wireless internet transmission based on signal quality conditions. When broadcast signal quality deteriorates due to fades or blockages, the system transitions to using wireless internet transmission, thereby adapting to changing environmental conditions and maintaining reliable data delivery.
2Reliability
If duplicate data transmission via alternative wireless communication is implemented, then reliability of data reception is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary error detection on broadcast transmission data before final reception. When errors are detected, the system has already prepared alternative data acquisition through wireless internet transmission, ensuring reliable data reception without requiring complex real-time switching mechanisms.
Solution Approach 2:
The patent implements a copying mechanism where the same data is transmitted through two different channels (broadcast and wireless internet). The receiver can compare or select between the original broadcast data and the copied data from wireless internet, improving reliability while keeping the system architecture relatively simple through this redundancy approach.
3Measurement precision
If error detection and correction mechanisms are added to digital radio broadcast reception, then data accuracy is improved, but processing time increases
Solution Approach 1:
Error detection is performed as a preliminary step in the data reception process. When errors are detected in broadcast transmission data, the system has already initiated or can quickly access alternative data from wireless internet transmission, thereby maintaining high data accuracy while minimizing additional processing time.
Data Source
AI summary
Systems and methods are described for rendering content at a digital radio broadcast receiver system. A digital radio broadcast signal comprises data for rendering content at the digital radio broadcast receiver. The digital radio broadcast signal is processed to determine whether the data from the digital radio broadcast transmission contains a data error. A portion of the data containing the data error is identified. A download request is transmitted to a computing system, where the download request requests duplicate data for the portion of the data containing the data error. The duplicate data is received at the digital radio broadcast receiver for the portion of the data containing the error via other wireless communication other than the digital radio broadcast. The duplicate data is processed to provide an uninterrupted rendering of the content.
