Audio Stream Buffering for Client-Initiated Error Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data streaming methods for audio recordings in healthcare environments are inefficient and prone to errors, particularly in unreliable networks, leading to incomplete or corrupted transmissions and non-compliance with regulatory requirements like HIPAA, and introduce significant latency and computational overhead.
Innovation Solution
A client device initiates data streaming with a local buffer to temporarily store data messages, including sequence numbers and timestamps, allowing for client-side error detection and recovery, ensuring data integrity and compliance by only maintaining ephemeral storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data messages are streamed without local buffering, then network bandwidth is conserved, but data integrity is compromised during network errors
Solution Approach 1:
The system performs preliminary action by buffering data messages locally before transmission. The client device stores data messages in a buffer with sequence numbers and timestamps, preparing them for potential retransmission without requiring full re-streaming, thus ensuring data integrity while managing network traffic efficiently.
Solution Approach 2:
The system implements discarding and recovering by maintaining buffered copies of data messages that can be recovered and retransmitted upon error detection. When network errors or server unavailability occurs, the client recovers from the buffer and retransmits incomplete or corrupted messages, ensuring data integrity without permanently losing information.
2Reliability
If server requests re-sending of audio recording, then data completeness is restored, but transmission time increases significantly
Solution Approach 1:
The client device performs preliminary action by pre-buffering data messages with sequence numbers and timestamps before transmission. This preparation enables rapid error detection and selective retransmission of only the specific incomplete or corrupted messages, rather than re-sending the entire audio recording, thus reducing retransmission time while maintaining transmission completeness.
Solution Approach 2:
The system applies segmentation by dividing the audio recording into discrete data messages with individual sequence numbers. This allows the client to identify and retransmit only the specific segmented messages that were lost or corrupted, rather than retransmitting the entire recording, thereby minimizing time loss while ensuring complete transmission.
3Reliability
If client stores buffered copy of data messages, then error recovery is enabled, but device memory consumption increases
Solution Approach 1:
The system implements discarding and recovering by maintaining buffered copies of data messages only temporarily for error recovery purposes. Once messages are successfully transmitted and acknowledged, or when the buffer reaches capacity, older or confirmed messages are discarded from the buffer, enabling error recovery capability while managing device memory consumption through selective retention and deletion.

AI summary
Techniques are disclosed for data streaming and aggregation with client initiated recovery. In an example method, a client device provides, to a computing system, a first data message including a first sequence number, a first timestamp, and a first payload, the first sequence number indicating a first position within the audio data stream to which the first payload corresponds. The client device stores the first data message in a buffer of the client device, the buffer comprising one or more buffered data messages. The client device determines a first error condition for the first data message based on at least one of the one or more buffered data messages or a first acknowledgement status of the first data message. Responsive to determining the first error condition for the first data message, the client device re-provides, to the computing system, the first data message.
