Master Server in a distributed system for transcoding video content used in OTT distribution

Zbog širenje dostupnosti interneta te razvoja novih i jeftinih mobilnih uređaja, video i audio sadržaji postali su dio svakodnevice modernog društva. Iako se brzina interneta razvila i u dolaznom i u odlaznom smijeru, internet velike brzine nije dostupan svima, što uzrokoje nemogućnost gledanja video sadržaja jednake kvalitete svima. OTT sustavi su dio rješenja ovog problema. Oni osiguravaju da svaki korisnik dobije najbolji mogući video koji njegova internet veza može ponijeti. Svaki OTT sustav je sastavljen od mnogo komponenti. Naš sistam je izgrađen u "Master - worker" arhitekturi i ima tri glavne komponente koje imaju nekoliko podkomponenti. Mozak cijelog sustava je Glavni server koji komunicira sa svim ostalim komponentama. Njegov posao je rukovati s poslovima koje šalje BMS te radnicima koji su spojeni na njega. Sve što se događa u sustavu se sprema u bazu.Due to the expansion of the Internet accessibility and development of new and cheap mobile devices, video and audio content became part of everyday modern society’s life. Nevertheless, huge evolution in internet download and upload speeds, very fast internet isn’t accessible to everyone, which is what causes that everyone can’t watch videos of the same quality. OTT systems are a part of solution to this problem. They ensure that every user gets the best possible video which his internet connection can stand. Every OTT system is built from many different components. Our system was built in a Master – Worker architecture and has three major components along with a few of their subcomponents. Brain of the system is a Master Server who communicates with all other components. Its job is to handle jobs which were sent from BMS and nodes that are connected to him. Everything that happens in the system has to be saved in the database
