Media Access Control Information Segmentation in Audio Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media access control systems face challenges in effectively transmitting and processing media access information within media streams, such as video or audio, due to limitations in existing technologies that lead to increased bit rates and potential interference with audio compressed data streams.
Innovation Solution
A transmission system that divides media access information into predetermined number of pieces and inserts them into audio frames within the media stream, allowing for efficient transmission and reception of media access control data without disrupting the audio stream, using a broadcast output device to prioritize the encoded stream format and ensure secure delivery of media access information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media access information is inserted into the audio stream, then the reception side can perform media access control, but the bit rate increases and may interfere with the audio compressed data stream
Solution Approach 1:
The media access information is divided into a predetermined number of pieces, and each piece is sequentially inserted into different audio frames within the audio stream. This segmentation approach distributes the information load across multiple frames, preventing any single frame from becoming overloaded and maintaining audio stream integrity while enabling complete media access control functionality at the reception side.
2Reliability
If media access information is inserted into the audio stream, then media access control can be performed, but the audio stream integrity may be compromised
Solution Approach 1:
Each audio frame is treated as a local unit with specific insertion capacity. The media access information pieces are selectively inserted into appropriate audio frames based on available space and frame characteristics, ensuring that frames maintain their structural integrity and decoding properties while collectively carrying the complete media access information.
3Loss of information
If large amount of media access information is transmitted, then complete control information is available, but transmission efficiency decreases and processing complexity increases
Solution Approach 1:
The media access information is segmented into multiple pieces that are distributed across audio frames. The reception side reconstructs the complete media access information by collecting and assembling these pieces in sequence, achieving complete information transmission while maintaining efficient use of the audio stream bandwidth and reducing processing overhead compared to transmitting all information in a single block.

AI summary
To enable a set of media access control to be favorably performed on the reception side. A container having a predetermined format is transmitted, the container including a media stream. A predetermined number of pieces of media access information associated for the set of media access control, are sequentially inserted into a layer of the media stream or a layer of the container. For example, the media access information includes identification information for making a distinction from different media access information and identification information for making an association with the different media access information.
