SYSTEM FOR FAULT-TOLERANT TRANSCODING AND OUTPUT OF DIRECT STREAMS IN HLS FORMAT Russian patent published in 2021 - IPC H04N21/00 

FIELD: computer technology.

SUBSTANCE: invention relates to computer technology. The fault-tolerant transcoding system and the issuance of direct streams in the HLS format contains a geographically distributed network infrastructure (CDN) for the issuance of chunklists and chunks of video produced by transcoding servers, and when requesting chunklists and chunks of video from the CDN, the CDN, due to a predefined configuration, performs an alternate search for chunklists and chunks of video on each of the cluster servers; load balancer for generating and sending commands to transcoding servers; a cluster of video transcoding servers under the unified control of the load balancer and made with the ability to: create chunklists and chunks of video; synchronization of chunks with each other through a distributed file system, moreover: video chunks are not synchronized between servers, but are located only on the server on which they are created, while by means of intermediate servers between the CDN and the transcoding cluster, all new chunks from the chunklist are forcibly and preemptively cached, and by means of the transcoder, when the transcoding server is changed, the existing file, the chunklist is read.

EFFECT: increasing the fault tolerance of video transcoding.
