Overview of technological capabilities for viewing of multimedia content on smart TV devices

Magistrsko delo obravnava tehnološke zmožnosti, ki nam jih ponujajo sodobne programske rešitve pri implementaciji aplikacij, ki so nameščene na pametnih televizorjih. V delu je najprej predstavljena zgodovina multimedijskih vsebin na televizorjih, poudarek je predvsem na tehnologiji teletekst, katerega osnovno delovanje je opisano. Predstavljene so faze prehoda TV naprav in oddajnikov iz analognih v digitalne sisteme, ki so odprli nove načine razvoja aplikacij in storitev za končne uporabnike. Obravnavi standarda HbbTV sledi osrednji del dela, kjer je obravnavan potek načrtovanja aplikacij in razvojnih vzorcev, ki predstavljajo sestavni del razvoja. Prikazani so praktični primeri različnih implementacij, tako aplikacij, ki ponujajo predvajanje na oddaljenem zaslonu, kot tudi aplikacije, ki s pomočjo tehnologije »WebView« deluje na Android TV sistemih. Za slednjo sta prikazana načrt in struktura, ki omogočata delovanje. Prenovljena aplikacija je bila izdelana z uporabo metode RAD (ang. Rapid Application Development), ki je primerna za manjše ekipe in je osnovana na prototipih, saj pri samem razvoju niso pričakovane bistvene spremembe v programju. V zadnjem delu je obravnavan postopek objave aplikacije v »spletni trgovini«.The master’s thesis deals with technological capabilities offered by modern software solutions when implementing apps, which are installed on smart televisions. At the beginning of the thesis is laid out the history of multimedia content on television, with a particular emphasis on the teletext technology, the basic functioning of which is described. The transition from TV devices and analogue transmitters to digital systems, which introduced new ways of developing apps and services for the users, is presented. In the next chapter the HbbTV standard is addressed, followed by the core of the thesis where the course of app development and development patterns, which are a constituent part of development, is discussed. The work provides practical examples of different implementations of apps, which offer »viewing for remote screens«, as well as the implementation of an app which operates on Android TV system with the help of »WebView« technology. A plan and structure, which enable its functioning, are displayed for the latter. The app has been developed with the RAD (ang. Rapid Application Development) methodology which is suitable for smaller teams and is based on prototypes, as no significant software changes are expected in the development phase. In the last part of the thesis the procedure of release of the app on »online shop« is discussed
