Abstract
Nowadays we are witnessing the development of digital broadcast television. One famous standard of digital broadcast is a Digital Video Broadcast (DVB). DVB is a family of standardize technologies designed to transmit video, audio, and multimedia services. In this work we develop small scale DVB system using computer equipped with DVB modulator to broadcast information or entertainment for students in a limited environment. The purpose of this research is to provide alternative solution in campus area that the students and academic community are able to develop an interactivity in learning, studying, or delivering home work or lesson material. To realize that, we develop DVB system using modulator DTA-110 and DTA-115 installed on the computer server. DTA-110 work on the Ubuntu operating system, while the DTA 115 works on Windows operating systems. Data in the form of video format TS (Transport Stream) emitted by an antenna connected to the modulator output. Then the data is received on the server re - stream with the help of a receiver dongle PC TV nano Stick. The parameters specified in the delivery of data, namely: frequency, guard interval, convolutional rate, constellation, and transmission mode. The performance of developed system is then evaluated and investigated in order the system is able to provide an acceptable performance to deliver such TV program or video.
