8.1 Introduction The earth segment of a satellite communications system consists of the transmit and receive earth stations. The simplest of these are the home TV receive-only (TVRO) systems, and the most complex are the terminal stations used for international communications networks. Also included in the earth segment are those stations which are on ships at sea, and commercial and military land and aeronautical mobile stations. As mentioned in Chap. 7, earth stations that are used for logistic support of satellites, such as providing the telemetry, tracking, and command (TT&C) functions, are considered as part of the space segment. 8.2 Receive-Only Home TV Systems Planned broadcasting directly to home TV receivers takes place in the Ku (12-GHz) band. This service is known as direct broadcast satellite (DBS) service. There is some variation in the frequency bands assigned to different geographic regions. In the Americas, for example, the downlink band is 12.2 to 12.7 GHz, as described in Sec. 1.4. The comparatively large satellite receiving dishes [ranging in diameter from about 1.83 m (6 ft) to about 3-m (10 ft) in some locations], which may be seen in some backyards are used to receive downlink TV signals at C band (4 GHz). Originally such downlink signals were never intended for home reception but for network relay to commercial TV outlets (VHF and UHF TV broadcast stations and cable TV head-end studios). Equipment is now marketed for home reception of C-band signals, and some manufacturers provide dual C-band/Ku-band equipment. A single mesh type reflector may be used which focuses the signals into a dual feedhorn, which has two separate outputs, one for the C-band signals and one

for the Ku-band signals. Much of television programming originates as first generation signals, also known as master broadcast quality signals. These are transmitted via satellite in the C band to the network headend stations, where they are retransmitted as compressed digital signals to cable and direct broadcast satellite providers. One of the advantages claimed by sellers of C-band equipment for home reception is that there is no loss of quality compared with the compressed digital signals. To take full advantage of C-band reception the home antenna has to be steerable to receive from different satellites, usually by means of a polar mount as described in Sec. 3.3. Another of the advantages, claimed for home C-band systems, is the larger number of satellites available for reception compared to what is available for direct broadcast satellite systems. Although many of the C-band transmissions are scrambled, there are free channels that can be received, and what are termed wild feeds. These are also free, but unannounced programs, of which details can be found in advance from various publications and Internet sources. C-band users can also subscribe to pay TV channels, and another advantage claimed is that subscription services are cheaper than DBS or cable because of the multiple-source programming available. The most widely advertised receiving system for C-band system appears to be 4DTV manufactured by Motorola. This enables reception of: 1. Free, analog signals and wild feeds 2. VideoCipher ll plus subscription services 3. Free DigiCipher 2 services 4. Subscription DigiCipher 2 services VideoCipher is the brand name for the equipment used to scramble analog TV signals. DigiCipher 2 is the name given to the digital compression standard used in digital transmissions. General information about C-band TV reception will be found at http://orbitmagazine.com/ (Orbit, 2005) and http://www.satellitetheater.com/ (Satellite Theater systems, 2005). The major differences between the Ku-band and the C-band receiveonly systems lies in the frequency of operation of the outdoor unit and the fact that satellites intended for DBS have much higher equivalent isotropic radiated power (EIRP), as shown in Table 1.4. As already mentioned C-band antennas are considerably larger than DBS antennas. For clarity, only the Ku-band system is described here. Figure 8.1 shows the main units in a home terminal DBS TV receiving system. Although there will be variations from system to system, the diagram covers the basic concept for analog [frequency modulated (FM)] TV. Direct-to-home digital TV, which is well on the way to replacing analog systems, is discussed in Chap. 16. However, the outdoor unit is similar for both systems.
