Audio Frame Information Marker Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in allowing the receiving side to readily and appropriately obtain predetermined information when it is divided into multiple audio frames and transmitted within a compressed audio data stream.
Innovation Solution
A transmission device that encodes audio data into compressed audio frames, inserts predetermined information into these frames, and adds specific markers to indicate the division position, enabling the receiving side to correctly identify and reassemble the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If predetermined information is divided and inserted into multiple audio frames, then the information can be transmitted within the audio stream structure, but the receiving side cannot readily identify and reassemble the divided information without additional markers
Solution Approach 1:
The transmission side adds first information (start markers) and second information (count markers) to each divided piece of predetermined information before insertion into audio frames. This preliminary action of adding identification markers enables the receiving side to easily identify and reassemble the divided information in the correct order, resolving the contradiction between complete information transmission and ease of retrieval.
2Productivity
If predetermined information is inserted into compressed audio data stream, then the information can be transmitted along with audio data, but the receiving side requires complex processing to extract and reassemble the information from multiple frames
Solution Approach 1:
By pre-adding first information and second information markers to each divided piece of predetermined information on the transmission side, the receiving side can simply read these markers to identify and reassemble the information without requiring complex extraction and matching algorithms, thus reducing processing complexity while maintaining transmission efficiency.
Solution Approach 2:
The first information and second information act as intermediary markers that facilitate the transfer of divided predetermined information from the transmission side to the receiving side. These markers serve as a bridge that simplifies the reassembly process by providing clear identification and ordering cues, reducing the complexity of information extraction at the receiving end.

AI summary
When predetermined information divided into a predetermined number of audio frames is transmitted, the receiving end is enabled to readily and appropriately obtain the predetermined information.An encoding process is performed on audio data, and a compressed audio data stream formed with successive audio frames including compressed audio data is generated. Predetermined information is inserted into the compressed audio data stream, and is then transmitted. The predetermined information is divided and inserted into a predetermined number of audio frames of the compressed audio data stream, and the first information indicating whether the current piece is the first piece of the divided information and the second information as a count number indicating the dividing position in descending order are added to each piece of the divided information.
