Abstract

BPG je slikovni format, osmišljen i definiran od strane programera Fabricea Bellarda 2014. godine. Zadatak ovog rada bio je prijenos slike uživo, primjenom podatkovnog formata BPG, a po uzoru na već postojeći format MJPEG.
Zadatak je riješen izradom sustava kojim se s mobilnog uređaja pogonjenog operacijskim sustavom Android putem mreže, a preko poslužitelja, slikovni okviri šalju web pregledniku na klijentskoj strani.
Usporedbom formata BPG i JPEG ustanovljeno je da format BPG ostvaruje puno veće sažimanje od formata JPEG, ali s druge strane, operacije kodiranja i dekodiranja puno duže traju.

Abstract (english)

BPG is a file format for coding digital images, which was created by programmer Fabrice Bellard in 2014. Subject of this article was to create live stream of BPG encoded images, which would be simmilar to an existing one which uses format MJPEG.
This task was solved by implementing a system, which uses an Android mobile phone to generate frames, then sending them through network to server, and then to client web browser.
By comparing formates BPG and JPEG it was concluded that BPG has higher compression ratio than JPEG, but it also takes mutch more time to encode or decode an image.
