Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio data reproduction techniques face interruptions due to unstable network conditions, where the audio data receiving speed is lower than the reproduction speed, leading to audio buffer depletion.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If audio data is reproduced while receiving continuously, then productivity is improved, but reliability deteriorates due to buffer depletion
Solution Approach 1:
The system performs preliminary actions by calculating the reproduction time required for upcoming audio data before actually reproducing it. This advance calculation allows the system to prepare and buffer audio data proactively, ensuring continuous reproduction without interruptions even when network conditions are unstable. The reproduction time calculation unit computes how long it will take to receive and process future audio data segments, enabling the system to maintain a safe buffer level throughout playback.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring the reproduction process and adjusting data reception accordingly. The position decision unit uses feedback from the reproduction time calculation to determine optimal insertion positions for receiving audio data, ensuring that data is received and buffered at the right moments to maintain continuous playback. This closed-loop control prevents buffer depletion by constantly adapting the reception schedule based on actual reproduction progress and network conditions.
2Productivity
If audio data receiving speed is lower than reproduction speed, then loss of substance occurs in the audio buffer, but continuing reproduction maintains productivity
Solution Approach 1:
The system performs preliminary actions by calculating the reproduction time required for upcoming audio data before actually reproducing it. This advance calculation allows the system to prepare and buffer audio data proactively, ensuring continuous reproduction without interruptions even when network conditions are unstable. The reproduction time calculation unit computes how long it will take to receive and process future audio data segments, enabling the system to maintain a safe buffer level throughout playback.
Solution Approach 2:
The system dynamically adjusts the audio data reception process based on real-time conditions. The position decision unit determines optimal insertion positions for receiving audio data by considering the current buffer state, reproduction progress, and network conditions. This dynamic approach allows the system to adapt the reception schedule continuously, ensuring that audio data is received at the right moments to maintain continuous playback without buffer depletion, even when receiving speed is lower than reproduction speed.

AI summary
An information processing apparatus including an audio buffer unit, a reproduction time calculation unit, a position decision unit; and an insertion unit. The audio buffer unit retains first audio data that have not been reproduced in the first audio data received from another apparatus via a transmission path. The reproduction time calculation unit calculates a reproduction time of second audio data on the basis of at least any of a state of the first audio data retained in the audio buffer unit or a state of the transmission path. The second audio data are to be inserted and reproduced while the first audio data are being reproduced. The position decision unit decides an insertion position of the second audio data in the first audio data. The insertion unit controls a process of inserting the second audio data at the insertion position in the first audio data.
