DEVELOPMENT OF VIDEO-ON-DEMAND SYSTEM

Diplomska naloga podrobno predstavlja vse gradnike, ki so potrebni za razvoj sistema »video na zahtevo«. V teoretičnem delu diplomske naloge smo predstavili celoten sistem »video na zahtevo«, ter njegovo funkcionalno vlogo v sistemu IPTV. Predstavili smo tako samo arhitekturo sistema »video na zahtevo«, kot tudi posamezne komponente znotraj sistema. Podrobneje smo opisali tudi standarde tehnologij za prenos, komunikacijske protokole za pretakanje vsebin, ter standarde za ustrezno pripravo avdio in video vsebin. V praktičnem delu smo predstavili sam razvoj lastne rešitve sistema »video na zahtevo«, ter orodja in programske pakete, ki smo jih uporabili pri implementaciji. Predstavili smo komunikacijo »od konca do konca« in sicer med odjemalcem, strežnikom podatkovne baze in video strežnikom. Za dodajanje vsebin v podatkovno bazo smo razvili namensko spletno aplikacijo, ki smo jo implementirali s pomočjo programskega jezika C#. Programska oprema na strani odjemalca je multimedijska platforma XBMC, za video strežnik pa smo uporabili Darwin Streaming Server platformo.In this thesis all widgets which are necessary for development of general »video on demand« system are presented into details. In the theoretical part of the thesis the whole »video on demand« system and its functionality within IPTV system is described. Especially, we described corresponding architecture and also individual modules of general »video on demand« system. Transfer protocols, communication standards and encoding standards for video and audio content are also described into details. In the implementation part of the thesis our solution of the »video on demand« system is presented. The implementation of the VOD system was made by using several tools and software packages which are also described. Also »end-to-end« communication between client, database server and video server is described. For adding content into the VOD system database, a web application, implemented in program language C# was developed. Client software is based on multimedia platform XBMC. For video server Darwin Streaming Server platform was used
