Text Data Reproduction for Uninterrupted Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for distributing audio content over communication networks face challenges where content reproduction is interrupted due to incomplete downloads or poor communication speeds, particularly when a client moves out of the base station's coverage area or when starting content reproduction before full data reception.
Innovation Solution
An information processing device equipped with a communication unit, audio data reproduction unit, and text data reproduction unit, controlled by a processor that switches to text data reproduction when audio data reproduction is not possible, allowing for seamless content playback by receiving and synthesizing text data, which has a smaller data amount and can be downloaded quickly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio data is downloaded and reproduced, then content reproduction quality is improved, but reproduction reliability deteriorates when client moves outside base station coverage or when download is incomplete
Solution Approach 1:
The patent introduces text data as an intermediary alternative to audio data. When audio data reproduction fails due to network issues or incomplete download, the system switches to reproducing text data, which has smaller data size and higher reliability, thereby maintaining content delivery continuity.
Solution Approach 2:
The system changes the data type parameter from audio data to text data when reproduction conditions deteriorate. This parameter change allows the system to adapt to varying network conditions and maintain reliable content reproduction by selecting the appropriate data type based on availability and reliability.
2Manufacturing precision
If audio data is reproduced, then content quality is improved, but reproduction time increases when data amount is large and communication speed is slow
Solution Approach 1:
The patent creates a textual representation (copy) of the audio content. This text copy can be downloaded and reproduced much faster than the original audio data, providing a time-efficient alternative that maintains content information while significantly reducing reproduction time.
Solution Approach 2:
The system reproduces only the essential information through text data rather than the complete audio data. This partial action approach maintains sufficient content quality for understanding while dramatically reducing the data amount and reproduction time required.
3Reliability
If text data is reproduced instead of audio data, then reproduction reliability is improved, but content quality may deteriorate
Solution Approach 1:
The system dynamically selects between audio data and text data based on real-time conditions. When audio reproduction conditions are good, it uses audio data for high quality. When conditions deteriorate, it switches to text data for reliable reproduction, creating a dynamic adaptation system that optimizes for reliability without permanently sacrificing quality.
Data Source
AI summary
An information processing device according to embodiments includes a communication unit configured to receive audio data of content and text data corresponding to the audio data, an audio data reproduction unit configured to perform reproduction of the audio data, a text data reproduction unit configured to perform the reproduction by audio synthesis of the text data, and a controller that controls the reproduction of the audio data or the text data. The controller causes the text data reproduction unit to perform the reproduction of the text data when the audio data reproduction unit is unable to perform the reproduction of the audio data.
