ABSTRAK

Jika dibandingkan dengan TV analog TV digital memiliki kualitas penerimaan yang lebih baik kebutuhan daya pancar yang lebih kecil ketahanan terhadap interferensi dan kondisi lintasan radio yang berubah-ubah terhadap waktu serta penggunaan bandwidth yang lebih efisien. Sistem pemancar TV digital dapat direalisasikan berbasis software dan berbasis hardware. Pada sistem pemancar TV digital DVB-T berbasis software sistem menggunakan software untuk mengelola menghasilkan proses multiplex dan membuat siaran dalam bentuk MPEG-2 termodulasi OFDM dan QAM. Pada tugas akhir ini dirancang pemancar TV digital DVB-T berbasis software open caster dan transmisi dilakukan berbasis PCI card modulator. Hasil yang di dapat dalam tugas akhir ini adalah realisasi TV digital DVB-T berbasis software dan analisis hasil pengukuran bentuk spektrum RFIF serta hasil pengukuran receiver sensitivity. Untuk mengetahui tingkat kepuasan penonton acara televisi terhadap siaran TV digital dilakukan metode MOS Mean Opinion Score pada setiap perubahan parameter modulasi. Hasil pengukuran menunjukan bahwa spektrum RF yang dihasilkan tidak menyimpang dari spektrum mask pada rekomendasi RRC 2006 tentang perencanaan sistem pemancar TV digital terestrial dan juga didapatkan power minimum dari receiver adalah dibawah -91dBm.


ABSTRACT

When compared to analog TV digital TV has a better reception quality the transmit power needs of the smaller resistance to radio interference and track conditions changing with time and bandwidth usage more efficient. Digital TV transmitter systems can be realized with software-based and hardware-based. At transmitter DVB-T system digital TV with software-based the system uses software to manage produce process and make the broadcast multiplex in the form of MPEG-2 modulated OFDM and QAM. In this thesis we designed a digital TV transmitter DVB-T software-based open-caster and transmission modulator was based PCI card. Results of the can in this thesis is the realization of digital TV DVB-T software-based measurement and analysis of the spectrum RF IF and receiver sensitivity measurements. To know the level of satisfaction with television viewers to digital TV broadcasting carried out the method MOS Mean Opinion Score at each change of modulation parameters. The measurement results show that the resulting RF spectrum does not deviate from the spectrum mask at the recommendation of the RRC in 2006 about the planning of terrestrial digital TV broadcasting system and also obtained the minimum of the receivers power is below-91dBm.
