Chapter 4. Digital TV by Satellite


This chapter is all about how to receive satellite TV signals. It includes everything on various; even more complicated, multifocus and motorized satellite reception antennas. The chapter also contains detailed instructions on how to calculate the elevation and azimuth angles that are needed to find the satellites when aligning the parabolic dish. In addition, there are also examples of instruments —in different price ranges —that may be used when optimizing the antennas. Low-noise block converters, (LNBs), and different kinds switches, such as DiSEqC are covered in detail.


Of course much attention is also paid to the set-top boxes and how the satellite TV signal is retrieved before being fed to the TV set or another display device. Here, modulation and the use of the DVB transport stream in satellite based distribution are discussed in detail.


This chapter includes a number of European satellite coverage maps and maps showing elevation and azimuth angles used to align satellite dishes toward European satellite orbital slots. (Appendix 2 contains American satellite coverage maps).  Tables indicate which antenna sizes are required at various satellite output power levels.


Chapter 4 contains 54 illustrations 4 of which are in the color insert.
