Description

Technical Field

[0001] The present invention belongs to the field of live broadcast technology, and in particular relates to an independent station live broadcast system based on cloud services and a construction method. Background Art

[0002] Currently, live broadcast technology generally uses streaming media servers as the core, such as using open source software such as OBS (OpenBroadcaster Software) for video capture and encoding, and pushing video streams to streaming media servers. However, this architecture is often limited by the server's processing power and network bandwidth when dealing with large-scale concurrent access, resulting in increased live broadcast delays, reduced image quality, and even service interruptions. In addition, single server deployment also faces problems such as slow regional access speeds and poor fault recovery capabilities.

[0003] In order to improve the fluency and coverage of live broadcasts, many live broadcast platforms have begun to introduce CDN (Content Delivery Network) acceleration technology, which deploys servers at multiple nodes around the world and caches video content to the node closest to the user, thereby shortening the transmission distance, reducing latency, and increasing access speed. However, traditional CDN services are often provided by third parties and are not highly coupled with the back-end systems of live broadcast platforms, making it difficult to achieve seamless docking and customized needs.

[0004] Technical problems of existing technologies: 1. High latency and instability: Traditional live broadcast architecture cannot guarantee low latency and stable live broadcast experience during peak hours, especially when accessing across regions, where latency is particularly prominent. 2. High cost: Building your own server and CDN network requires huge initial investment and ongoing operation and maintenance costs, which is a heavy burden for small and medium-sized live streaming platforms; 3. Poor scalability: As the user scale grows, traditional architectures are difficult to quickly expand to meet higher concurrency requirements; 4. Difficulty in customization: Third-party CDN services usually provide standardized solutions, which are difficult to meet the special needs of live streaming platforms in terms of function customization, data analysis, etc. Summary of the invention
