Information Processing Device Sound Quality Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in reproducing musical pieces with satisfactory sound quality due to varying bit rates from different content providers, making it challenging to select the optimal source for playback.
Innovation Solution
An information processing device with a control unit that acquires user utterances, searches for sound sources capable of providing the requested musical piece via wireless communication, acquires sound quality information, selects the source with the highest sound quality, and plays back the musical piece from that source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sound sources are searched for the same musical piece, then the user can access more content providers, but it becomes difficult to select the optimal source due to varying bit rates
Solution Approach 1:
The system automatically compares bit rates from multiple sound sources and selects the optimal source without requiring user intervention. The control unit performs the selection task autonomously by evaluating the bit rate information and choosing the sound source with the highest bit rate, thereby resolving the contradiction between accessing multiple providers and ease of selection.
2Manufacturing precision
If the system automatically selects sound sources based on bit rate comparison, then sound quality is maximized, but the system complexity increases
Solution Approach 1:
The system performs preliminary actions by acquiring bit rate information from multiple sound sources before the actual music playback. This advance comparison and selection process ensures that the optimal sound source is identified in advance, maximizing sound quality while keeping the complexity manageable through structured preliminary processing.
Solution Approach 2:
The system uses bit rate as a key parameter to evaluate and compare different sound sources. By focusing on this specific parameter (bit rate) rather than analyzing all possible audio qualities, the system achieves effective sound quality optimization with relatively simple processing logic, thus resolving the contradiction between quality and complexity.

AI summary
A control unit is provided to execute: acquiring a user's utterance; searching a first sound source capable of providing a first music piece via wireless communication in response to a request for reproducing a first music piece being included in a user's utterance; acquiring information regarding the sound quality of the first music piece for each of the plurality of first sound pieces in response to the plurality of first sound pieces being present; selecting a second sound piece having the highest sound quality among the plurality of first sound pieces; and reproducing a first music piece provided from the second sound piece.
