Subjektivno vrednotenje kakovosti prenosa videa v komercialnem mobilnem omrežju

PEČENKO, IGOR (author), Burnik, Urban (mentor)

V pričujočem diplomskem delu je predstavljeno subjektivno ocenjevanje kakovosti video posnetkov, procesiranih preko naprave Ikusnet, ki omogoča prenos podatkov preko komercialnega mobilnega podatkovnega omrežja LTE, za potrebe televizijske produkcije. Glavni cilj dela je ugotoviti, ali naprava Ikusnet ustreza kriterijem kakovosti video posnetkov televizijske produkcije RTV Slovenija. Uvodoma opišemo napravo Ikusnet, njene lastnosti, načine delovanja in področja uporabe, kot tudi namen uporabe na RTV Slovenija. Sledi predstavitev metod subjektivnega ocenjevanja kakovosti video posnetkov in njihovih prednosti. Nato predstavimo izvedbo testiranja, ki je zajemalo prenos video posnetkov z napravo Ikusnet preko komercialnega mobilnega podatkovnega omrežja LTE ter izvedbo subjektivnega ocenjevanja kakovosti prenesenih posnetkov. Rezultati ocenjevanja kažejo, da naprava Ikusnet ne zagotavlja primerne kakovosti prenosa video posnetkov za distribucijo daljših TV signalov, ustreza pa kriterijem RTV Slovenija za načrtovana in naključna javljanja v oddaje. V zaključku sledi krajša razprava o možnostih uporabe naprav za prenos TV signalov preko komercialnega mobilnega podatkovnega omrežja LTE.

• Title: Subjective evaluation of the video transmission quality over a commercial mobile network

Abstract

This thesis presents a subjective quality assessment of video processed through the device Ikusnet, which enables data transmission via a commercial LTE mobile data network for the needs of TV broadcasting. The main objective of the thesis is to determine whether Ikusnet meets the video quality criteria for RTV Slovenia's TV production. The description, features, modes of operation and applications of the device Ikusnet by Prodys are given in the initial chapter, as well as the purpose of the device's use at RTV Slovenia. Next, we present different methods of subjective video quality assessment and their advantages. This is followed by a description of the implementation of the video quality assessment, which entailed video transmission via a commercial LTE mobile data network and subsequent subjective quality assessment of the transmitted footage. Results indicate that Ikusnet does not provide adequate video quality for longer TV broadcasting signals. On the other hand, it satifies the criteria of RTV Slovenia for planned and ad-hoc news broadcasts of shorther length. We conclude with a discussion of the possibilities of the device's usage that allow for the transfer of broadcasting TV signals via a commercial LTE mobile data network.
