Mix Instructions File Packet Segmentation for Real-Time Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music mix files become large due to embedded instructions and music files, making real-time sharing and playback inefficient, especially when retrieving files from remote locations over networks.
Innovation Solution
A mix instructions file is divided into packets with advance pointers and complete playback state information, allowing for near real-time transmission and playback, enabling remote creation and immediate playback with minimal delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mix instructions file is transmitted in full before playback, then complete playback state information is available, but transmission time increases significantly
Solution Approach 1:
The mix instructions file is divided into multiple packets, where each packet contains a segment of the playback instructions. This segmentation allows progressive transmission of data, reducing overall transmission time while maintaining complete playback state information in each packet for reliable playback reconstruction.
Solution Approach 2:
Each packet contains complete playback state information at its starting point, prepared in advance. This preliminary inclusion of state information allows the playback device to reconstruct the mix state without waiting for the entire file to be transmitted, significantly reducing transmission time while ensuring reliability.
2Loss of time
If packets are transmitted progressively during mix creation, then transmission time is reduced, but playback state continuity may be interrupted
Solution Approach 1:
Complete playback state information is preliminarily included in each packet at its starting point. This ensures that even when packets are transmitted progressively during mix creation, each packet maintains the stability and continuity of playback state composition, allowing uninterrupted playback reconstruction.
Solution Approach 2:
The playback state information in each packet serves as feedback that allows the playback device to verify and maintain continuous playback state. This feedback mechanism ensures stability and continuity even when packets are transmitted progressively without waiting for the complete mix creation.
3Productivity
If advance pointers are added to enable early music track retrieval, then playback readiness is improved, but file size increases
Solution Approach 1:
The mix instructions file is segmented into packets with advance pointers indicating future music track retrieval points. This segmentation allows the system to prepare for upcoming tracks without including the entire music library, improving playback readiness while minimizing the increase in file size through selective advancement information.

AI summary
A mix instructions file is provided, for controlling the playback of at least one music track file said mix instruction file comprising instructions including an indication of the at least one music track file at the point in time when the at least one music track file is to be accessed, and at least one function for manipulating the output of the at least one music track file, the sum of the indication of the at least one music track file and the at least one function constituting the state of the mix, said mix instruction file comprising at least a first and a second packet, that may be transmitted independently of each other, the second packet holding information about the playback state of the mix at the corresponding end of the first packet.
