Audio Device Automatic Music Saving via Broadcast Time Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices require manual registration of musical pieces one by one for saving, which is inefficient.
Innovation Solution
An audio device with a first broadcast processor, reproduction unit, first storage, controller, and second storage that automatically receives and saves musical piece data based on a broadcast time table, allowing for high-quality audio data storage and optional audio quality selection and complementation through communication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual registration of musical pieces is implemented one by one, then accurate control of saved musical pieces is achieved, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary actions by automatically acquiring broadcast time tables and pre-processing audio data during broadcast transmission. When users want to save musical pieces, the data is already prepared and organized, eliminating the need for manual registration and significantly improving saving efficiency while maintaining ease of operation.
Solution Approach 2:
The system enables self-service by automatically identifying, extracting, and organizing musical piece data from broadcast signals without requiring user intervention. The controller autonomously manages the saving process based on broadcast time tables, allowing users to simply select what to save rather than manually registering each piece.
2Reliability
If only single broadcast wave reception is used, then device complexity is reduced, but audio quality may be insufficient
Solution Approach 1:
The system merges multiple broadcast waves (first and second broadcast processors) to receive the same broadcast content through different transmission paths. By combining these reception channels, the system ensures high audio quality through selective reproduction while maintaining manageable device complexity through integrated control logic.
Solution Approach 2:
The system changes reception parameters by selecting between different broadcast waves based on audio quality detection. The selector unit dynamically adjusts which broadcast signal to use, optimizing audio quality without requiring complex manual configuration or multiple simultaneously active reception paths.

AI summary
An audio device includes a first broadcast processor configured to execute reception processing of a first broadcast wave to generate a first reproduction signal, a reproduction unit configured to reproduce audio based on the first reproduction signal, a first storage configured to temporarily store audio data related to the first reproduction signal, a controller configured to acquire a time table of a broadcast related to the first broadcast wave and receive a saving instruction of a musical piece from a user, and a second storage configured to, when the controller receives the saving instruction, cut first musical piece data of a predetermined musical piece depending on a reception time of the saving instruction from the audio data temporarily stored in the first storage based on the time table and store the first musical piece data.
