Sažetak

Mjerenje kvalitete predstavlja osnovni zahtjev suvremenih multimedijskih komunikacijskih sustava kako zbog tehničkih tako i zbog komercijalnih i pravnih razloga. Mjerenja kvalitete provodi se s pomoću objektivnih metoda koje još uvijek nisu normirane. Dobiveni rezultati trebali bi biti u velikoj korelaciji s rezultatima subjektivnih ispitivanja kvalite. U skladu s tim razvijene su metode koje daju djelomična vrednovanja kavalitete.

Ključne riječi: multimedijske komunikacije, kvaliteta usluge, objektivana mjerenja, subjektivna ispitivanja

Abstract

Th e quality measurement is a basic requirement of modern multimedia communication systems due to the technical and the commercial and legal reasons. Th e quality measurement is carried out using objective methods which have not yet been standardized. Th e results should be in great correlation with the results of subjective quality tests. Accordingly, methods have been developed which provide a partial evaluation of the quality.

Keywords: multimedia communication, quality of service, objective measurements, subjective tests

Patrik Ervells latest collection is ironically titled “Software”ADIDAS ORIGINALS TUBULAR SHADOW. In the notes from the presentation, Ervell says he was interested in developing tension between nostalgia and sci-fi,NIKE ZOOM WINFLO 3 and even included 90s cyberpunk amongst his influences. Ervell developed this point of view by creating an imaginary software company called Idegen software systems. He then re-appropriated the company’AIR JORDAN XXXI MENs logo in several of the collection’s garments. Elsewhere,MBT TARIKI MEN mohair coats with oversized lapels made an appearance alongside mock neck tees,NIKE AIR JORDAN RETRO 5 police-inspired ribbed sweaters,MBT FORA GTX WOMEN flight bombers, and polyurethane leather coats. The setting was also suitably dystopian, and the resulting ambiance was something akin to if the creators of Deutschland 83 and Hackers met up and decided to create a collection… We mean that as a compliment.Yesterday afternoon,JORDAN CP3 IX MEN artist JR spent the day working on his latest collaborative piece with Daniel Arsham in Greenpoint,NIKE AIR MAX 90 Brooklyn,MBT KIMONDO GTX MEN NYC. Connecting the lines between art, architecture, dance and theater, Daniel Arsham has been known to subvert existing architectural structures in unconventional,NIKE CLASSIC CORTEZ NYLON playful ways; confusing and confounding the expectations of space and form.
