Structure of the Report Chapter 1 describes the current available technologies for digital terrestrial TV broadcasting. After some general remarks the subsections deal with a detailed description of the transmitting and receiving path of the appropriate standards. Chapter 2 describes the different possible technologies for digital terrestrial sound broadcasting and provides some additional information to laboratory and field measurements as well as regulatory aspects. Chapter 3 summarizes the given information from the participating countries. Chapter 4 includes the detailed information to the questionnaire from each country. 1 Digital Terrestrial Television Broadcasting The Digital Video Broadcasting Project (DVB) is an industry-led consortium of around 250 broadcasters, manufacturers, network operators, software developers, regulatory bodies and others in over 35 countries committed to designing open technical standards for the global delivery of digital television and data services. Services using DVB standards are available on every continent with more than 600 million DVB receivers deployed. The DVB Worldwide section offers country-by-country news stories and an overview of where DVB technology has been deployed. 1.1 DVB-T DVB-T is an abbreviation for Digital Video Broadcasting — Terrestrial; it is the DVB European- based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 and first broadcast in the UK in 1998. This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation. Following the official DVB-T Logo: 1.1.1 Basics of DVB-T Rather than carrying the data on a single radio frequency carrier, OFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulate a set of closely spaced adjacent carrier frequencies. In the case of DVB-T, there are two choices for the number of carriers known as 2K-mode or 8K-mode. These are actually 1,705 or 6,817 carriers that are approximately 4 kHz or 1 kHz apart. Document name / version: Assesment of the technical framework / R-1.1 Page: 4/84 DVB-T offers three different modulation schemes (QPSK, 16QAM, 64QAM). DVB-T has been adopted or proposed for digital television broadcasting by many countries (see map), using mainly VHF 7 MHz and UHF 8 MHz channels whereas Taiwan, Colombia, Panama, Trinidad and Tobago and the Philippines use 6 MHz channels. The DVB-T Standard is published as EN 300 744, Framing structure, channel coding and modulation for digital terrestrial television. This is available from the ETSI website, as is ETSI TS 101 154, Specification for the use of Video and Audio Coding in Broadcasting Applications based on the MPEG-2 Transport Stream, which gives details of the DVB use of source coding methods for MPEG-2 and, more recently, H.264/MPEG-4 AVC as well as audio encoding systems. Many countries that have adopted DVB-T have published standards for their implementation. These include the D-book in the UK, the Italian DGTVi, the ETSI E-Book and Scandivia NorDig. DVB-T has been further developed into newer standards such as DVB-H
