Chapter 6. Digital TV by Terrestrial Transmitters


Terrestrial television has survived the introduction of cable, broadband and satellite. Today, it is still the basic way of receiving television in many countries. Chapter 6 contains lots of information on antennas as well as detailed information on the DVB-T standard based on COFDM —one of the most advanced modulation schemes ever introduced. The design and advantages of this system are discussed along with the details about set-top boxes. Possible reception problems in single frequency networks (SFN) and ways to avoid these problems are covered. (The American ATSC-standard for digital terrestrial TV is covered in Appendix 1). There is also a section in mobile terrestrial television, —DVB-H.


Chapter 6 contains 22 illustrations.



Many in-house filtering amplifiers have two outputs, making it easy to connect two TV sets with no losses.
