Playlist Generator for Live Streaming Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing live streaming systems struggle to efficiently integrate and generate a complete playlist or playback file from separate stream segments, especially when internet connections are unstable or when streamers switch between different streaming servers.
Innovation Solution
A method and system for playlist generation that involves obtaining stream portion information and a unique key from multiple streaming servers, determining consistent stream portions on a cloud server, and updating a playlist file accordingly, ensuring seamless integration of stream segments into a complete playback file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stream segments are stored on multiple separate streaming servers, then system reliability and adaptability improve, but playlist generation complexity and difficulty of detecting and measuring stream portion consistency increase
Solution Approach 1:
The patent introduces a playlist generator as an intermediary component that coordinates between multiple streaming servers and the playback system. This mediator collects stream portion information from different servers, verifies consistency through unique keys and timestamps, and generates the unified playlist file, thereby simplifying the complexity of direct multi-server coordination
Solution Approach 2:
The system implements feedback mechanisms where the playlist generator continuously monitors stream portion information from multiple servers, verifies consistency through unique keys and timestamps, and updates the playlist file accordingly. This feedback loop ensures reliable integration of stream segments while maintaining manageable complexity through automated verification
2Adaptability or versatility
If stream segments are distributed across multiple servers, then system adaptability improves, but device complexity for integrating and generating playlists increases
Solution Approach 1:
The patent divides the streaming system into distinct segments: multiple independent streaming servers that store stream portions, a separate playlist generator that manages integration, and a unified playlist file that coordinates playback. This segmentation allows each component to function independently while maintaining overall system adaptability across multiple servers
Solution Approach 2:
The playlist generator serves multiple functions: it collects stream portion information from various servers, verifies consistency using unique keys and timestamps, generates the unified playlist file, and updates the file as new segments become available. This multi-functionality reduces the need for separate specialized components, thereby managing device complexity while maintaining adaptability
3Manufacturing precision
If complete playlist generation waits for all stream segments, then manufacturing precision of the playlist file improves, but productivity and generation speed decrease
Solution Approach 1:
The system performs preliminary actions by generating the initial playlist file as soon as the first stream portion information is available, rather than waiting for all segments. The playlist generator creates a preliminary playlist with available segments and continuously updates it as more stream portions become available from multiple servers, thereby achieving both speed and completeness
Solution Approach 2:
The playlist file is designed to be dynamic rather than static. The playlist generator continuously monitors for new stream portion information from multiple servers and updates the playlist file in real-time. This dynamic approach allows the playlist to evolve from incomplete to complete, balancing generation speed with file precision

AI summary
The present disclosure relates to a system and a method for playlist generation. The method includes: obtaining a first stream portion information and a unique key from a first streaming server; determining a first set of stream portions stored on a space of a cloud server to be consistent with the first stream portion information, the space being addressable by the unique key; generating a playlist file according to the first stream portion information; obtaining a second stream portion information and the unique key from a second streaming server; determining a second set of stream portions stored on the space of the cloud server to be consistent with the second stream portion information; and updating the playlist file according to the second stream portion information.
