Abstract

U profesionalnoj produkciji multimedijskih sadržaja koriste se studijske video kamere povezane s naprednim sustavima za praćenje kamere (engl. camera tracking system) koji omogućavaju automatizaciju praćenja sadržaja kamerom sukladno specifičnim potrebama sadržaja koji se snima. Prilikom montaže snimljenog materijala potrebno je vremenski uskladiti video sadržaj s podacima iz sustava za praćenje. Metoda koja omogućuje jednostavno usklađivanje podataka iz sustava za praćenje i video materijala temelji se na korištenju audio ulaza kamere u svrhu snimanja sekvenci dobivenih od sustava za praćenje. U okviru rada razvijen je ugradbeni računalni sustav koji prima digitalne podatke iz sustava za praćenje putem lokalne mreže (Ethernet) i konvertira ih u stvarnom vremenu u audio signal koji se žično šalje prema audio ulazu kamere. Razvijen je postupak amplitudne modulacije audio signala koji omogućava prijenos digitalnih podataka primljenih s Ethernet sučelja prema mikrofonskom ulazu kamere. Izrađena je tiskana pločica koja sadrži napajanje, mikrokontroler, D/A pretvornik, Ethernet sučelje i audio izlaz. Razvijena je programska potpora za čitanje podataka s Ethernet sučelja i modulaciju audio signala.

Abstract (english)

In the professional production of multimedia content studio video cameras are used in conjunction with advanced camera tracking systems, which enable the automation of camera content tracking in accordance with the specific needs of the content being recorded. During the process of editing the recorded material, it is necessary to synchronize the video content with data from the camera tracking monitoring system. The method that allows easy synchronization of data from camera tracking system and video content is based on the use of camera's audio input for the purpose of recording sequences obtained from camera tracking system. Embedded system that receives digital data from the camera tracking system via Ethernet and converts it in a real time into audio signal wired to the camera's audio input was developed. Amplitude modulation procedure that allows transmission of digital data received from the Ethernet interface to the camera's audio input was developed. Printed circuit board that contains power supply, microcontroller, D/A converter, Ethernet, and audio output was developed. Software for receiving camera tracking data from Ethernet interface and audio modulation was developed.
