Будущее цифрового телевизионного вещания: 4К, 8К, HEVC, HDR, далее везде

The analysis of normative and technical documents for the European broadcasting zone issued in 2019 was carried out. The main trend and development goal of the TV industry is the transition to Ultra High Definition image formats combined with High Dynamic Range, High Frame Rate and immersive sound. It is shown that the practical implementation of new digital TV broadcasting technologies is lagging behind their development and international standardization. Проведен анализ нормативно-технических документов для европейской зоны вещания, изданных в 2019 г. Основными тенденциями и целями развития отрасли является переход на форматы вещания изображений сверхвысокой четкости в сочетании с большим динамическим диапазоном, высокой частотой кадров и иммерсивным звуком. Показано, что внедрение в практику новых технологий цифрового ТВ-вещания происходит с отставанием от их разработки и международной стандартизации.

Perancangan dan Realisasi Antena Mikrostrip Fraktal Kӧch untuk Aplikasi TV Digital di Dalam Ruangan

ABSTRAK Siaran TV digital umumnya menggunakan antena tipe Yagi dan Kubikal yang berukuran besar sehingga tidak fleksibel digunakan di dalam ruangan. Penelitian ini merancang dan merealisasikan antena mikrostrip miniaturisasi fraktal Köch agar dimensi antena lebih kecil dan bandwidth lebih besar sehingga cocok digunakan di dalam ruangan. Miniaturisasi antena berupa fraktal Köch iterasi-1 pada patch dan teknik slot iterasi-2 pada ground plane menggunakan pencatuan mikrostrip proximity coupled feed pada alokasi frekuensi TV digital Indonesia 478 – 694 MHz dengan bandwidth 216 MHz. Antena dirancang pada software perancang antena, direalisasikan, diukur, dan diaplikasikan pada TV digital. Hasil simulasi antena menunjukkan bandwidth yang lebih besar dari spesifikasi yaitu 245,99 MHz pada rentang frekuensi 477,81 – 723,8 MHz. Return loss dan gain untuk direalisasikan sebesar -16,67 dB dan 3,085 dB pada frekuensi tengah 586 MHz. Pola radiasi berbentuk bidirectional dan polarisasi berbentuk linier. Panjang dan lebar antena hasil realisasi 17,33 cm X 17,33 cm. Kata Kunci: TV digital, antena, mikrostrip, Fraktal, Köch ABSTRAC Digital TV broadcasting generally uses large Yagi and Cubical type antennas, so it is not flexible to be used indoor. This study designs and applies miniaturization of Köch fractal microstrip antennas to obtain smaller dimensions and larger bandwidth. The miniaturization of antenna are Köch fractal iteration-1 on patch and iteration-2 slot technique on ground plane using proximity coupled feed at frequency allocation 478 – 694 MHz and the bandwidth is 216 MHz. The antenna was designed in software and developed, measured, and applied to digital TV. Antenna simulation results show a greater bandwidth than specification, 245.99 MHz, at the frequency range of 477.81 – 723.8 MHz. Return loss and gain simulation results that meet the specifications to be applied to digital TV antennas are -16.67 and 3.085 dB at 586 MHz center frequency. The radiation pattern is bidirectional and polarization is linear. The length and width dimensions of the antenna is 17.33 cm × 17.33 cm. Keywords: TV digital, antenna, microstrip, Fractal, Köch

Modelling and Performance Evaluation of WiMAX 700 to Work as Secondary User in Spectrum of the Digital Television Broadcasting Terrestrial through the Cognitive Radio Network

The cognitive radio network (CRN) is considered as one of the most important technologies that can allow the different users work as the same spectrum by different priorities. This paper proposes new methods and solutions to implement and performance analysis of work the WiMAX system within the spectrum of digital television broadcasting terrestrial through the cognitive radio network under various conditioning and types of modulation. Also, this paper explains and analyze the mechanism in which the cognitive radio works. Finally will be designed a prototype device simulate work the WiMAX system as a secondary user in digital TV broadcasting through the cognitive radio techniques.

Adoption factors to digital TV platforms in Turkey

The main aim of this study is to understand digital TV platform adopters’ media usage and adopting factors by identifying their profile in Turkey. According to this aim, it was tried to find out the demographic characteristics of digital TV broadcasting adopters, media usage level and the factors of adopting. In addition, it was tried to find out demographic variables, media usage frequency differences between adopters of digital TV platform and non-adopters. The result of analysis shows that, while it was found significant differences between adopters’ and non-adopters’ education; was not found significant differences between adopters’ and non-adopters’ age and sex. There is no significant differences between adopters’ and non-adopters’ media uses. According to the results of factor analysis shows that there are 5 reason to adopting digital TV platform.

Russia's Contribution to Digital TV Broadcasting

In the second decade of the 21st century, the interconnection and even interdependence between the qualitative characteristics of modern screen produce and screen arts in general and those of rapidly developing innovative technologies becomes increasingly obvious. tte affinity of different academic problems pertaining to the analysis of film industry, in humanities and science in particular, raises a lot of questions. One of them deals with revealing the factors necessary for the international recognition of a fundamental project and its subsequent implementation. This issue is illustrated in the article by the history of terrestrial television which has evolved from analogue broadcasting to digital, multi-program, interactive TV.

Pengaruh Faktor-Faktor Penerimaan Masyarakat Terhadap Simulcast Free To Air TV Digital

<p><strong>Abstrak</strong></p><p>Indonesia memasuki era penyiaran televisi digital, dan saat ini berada pada masa transisi. Pada periode transisi, sinyal analog dan digital dipancarkan secara bersamaan yang dikenal dengan masa <em>simulcast</em>. Selain untuk tetap menjamin hak masyarakat mendapatkan informasi melalui media TV, tujuan masa transisi adalah agar masyarakat mulai melakukan peralihan ke siaran digital.</p><p>Proses digitalisasi tidak hanya melibatkan teknologi, melainkan juga perubahan cara pandang terhadap berbagai aspek yang lahir dari teknologi digital tersebut. Keberhasilan migrasi analog digital ini perlu dibangun melalui kesadaran masyarakat untuk beralih tanpa paksaan sehingga faktor penerimaan masyarakat atas implementasi siaran digital perlu diperhatikan. Penelitian ini dilakukan untuk melihat faktor apa saja yang berpengaruh dan seberapa besar pengaruh pada penerimaan masyarakat terhadap siaran televisi digital di masa <em>simulcast </em>dengan konsep penerimaan teknologi baru oleh masyarakat dengan menggunakan teori penerimaan <em>Unified Theory of Acceptance and Use of Technology (UTAUT)</em>. Analisis dilakukan dengan analisis jalur untuk mengetahui tingkat signifikan variabel dan seberapa besar koefisien jalur memberikan pengaruh. Secara keseluruhan faktor-faktor yang memengaruhi penerimaan masyarakat dalam model penelitian ini memberikan besaran pengaruh variabel sebesar 53%, sedangkan sisanya 47% menyiratkan ada variabel-variabel lain yang berpengaruh dalam penerimaan masyarakat terhadap siaran TV digital <em>free to air </em>di masa <em>simulcast.</em></p><p><strong> </strong></p><p align="center"><strong><em> </em></strong></p><p><strong><em>Abstract</em></strong></p><p><em>Indonesia </em><em>has </em><em>entered the era of digital television broadcasting and</em><em> it</em><em> is currently in a transition period.
