Abstract:V diplomski nalogi sta opisana realizacij in ovrednotenje prenosa slike in zvoka v živo s pomočjo sistema za pretvorbo spletnih avdiovizualnih vsebin v DVB transportne tokove. Opisan je prenos slike in zvoka v realnem času s pomočjo spletne kamere, katere avdiovizualna vsebina se zajema z multimedijskim predvajalnikom VideoLan. Le-ta v nadaljevanju pošilja zajeti zvok in sliko po internetnem protokolu na lokalni naslov računalnika znotraj lokalnega omrežja na predhodno definirana vrata. Na takšen način posredovano avdiovizualno vsebino se iz omrežja odvzema s pomočjo programa FFMPEG, ki sprejeto vsebino pretvarja v standardni MPEG-2 transportni tok. Novo ustvarjen transportni tok se z uporabo internetnega nepovezovalnega protokola ponovno posreduje v lokalno ali drugo omrežje na predhodno definiran internetni naslov in pripadajoča vrata. Izveden je bil nov program za sprejem transportnih tokov iz omrežja in za posredovanje le teh na oddajni pretvornik z USB vmesnikom in standardnim ASI izhodom. Da smo zagotovili celovitost preizkušanja prenosne poti, se omenjen signal sprejema z dodatnim ASI pretvornikom z USB vmesnikom, pri tem pa je možno spremljanje posredovane avdiovizualne vsebine s programom za digitalno televizijo. Prav tako je možno ustvarjen ASI signal posredovati na DVB oddajnik in ga spremljati s standardnim digitalnim televizijskim sprejemnikom.

Title:REAL TIME SYSTEM FOR AVDIOVISUAL WEB CONTENT CONVERSION IN DVB TRANSPORT STREAM
Abstract:The thesis describes the realisation, implementation and evaluation of the transfer of video and audio live with the system for converting audio-visual content online into DVB transport streams. It describes the transmission of video and audio in real time using a web camera, which audio visual content is covered by the media player VideoLan. This media player is sending the sound and image through the Internet Protocol to the address of the computer on a local LAN within the pre-defined port. Once the audio visual content is transmitted, it is taken from the network with the program FFMPEG, which converts the received content in standard MPEG-2 transport stream. The new transport stream will be with help of the unconnected Internet Protocol transmited again to the local or other network, to the pre-defined internet address and associated port. With this it was carried out a new program for the reception of transport streams from the network and their transmission to the transmitting transducer with USB adapter and a standard ASI output. For ensuring the integrity of testing the transmission path, the signal mentioned before is beeing received with additional ASI converter with USB interface. Meanwhile it is possible to monitor the audio visual content with the program for digital television program. It is also possible to transmit the ASI signal to DVB transmitter and monotoring it with a standard digital TV receiver.
