Abstract

Cilj ovog diplomskog rada je prikazati na koji način emisije radiodifuznih sustava utječu na kvalitetu DVB-C video usluga. Detaljno su prikazane značajke DVB-C standarda i arhitektura HFC mreže, u svrhu prikaza načina funkcioniranja usluga. Opisan je alat koji pružatelji DVB-C video usluga koriste kako bi svojim korisnicima omogućili stabilnu uslugu. Na realnim primjerima je prikazano koliki su utjecaji radiodifuznih sustava na kvalitetu usluge i s kojim se sve problemima susreću pružatelji usluga dok degradaciju usluge pokušavaju svesti na minimum. Opisana su provedena testiranja i mjerenja koja su bila potrebna kako bi se identificirao nedostatak koji utječe na degradaciju usluge uslijed emisija radiodifuznih sustava.

Abstract (english)

This thesis aims to provide the way that emissions from broadcasting systems affect on quality of DVB-C video services. DVB-C standards and HFC network architecture are presented in detail, in order to show how the services work. It describes the tool that DVB-C video service providers use to provide their customers with a stable service. It is shown on real examples what is the impact of broadcasting systems on the quality of service and the real problems that service providers face while trying to minimize service degradation. The tests and measurements performed that were necessary to identify the deficiency affecting the degradation of the service due to the emissions of the broadcasting systems are described.
