names (H.264, H.26L, ISO/IEC 14496-10, JVT, MPEG-4 AVC, and MPEG-4 Part 10) and the abbreviation AVC is commonly used to denote advanced video coding. Following the usage in Sullivan et al., it will be denoted here by H.264/AVC. Areas of application include video telephony, video storage and retrieval (DVD and hard disk), digital video broadcast, and others. In general terms, MPEG-4 provides many features not present with other compression schemes, such as interactivity for viewers, where objects within a scene can be manipulated, but from the point of view of satellite television, the major advantage is the reduction in bit rate offered. About a 2:1 reduction in bit rate, on average is achievable with H.264/AVC compared with MPEG-2, and in July 2004, an amendment known as fidelity range extensions (FRExt, amendment 1) was added to H.264/AVC that can provide a reduction of as much as 3:1 in certain situations (Sullivan et al., 2004). FRExt supports 4:2:2 and 4:4:4 sampling. As with MPEG-2 the analog outputs from the red (R), green (G), and blue (B) color cameras are converted to a luminance component (Y) and two chrominance components (Cr) and (Cb) but with a different M matrix, this being: Y C Cr S Cb 0.2126 C 0.119977 0.561626 0.587 0.331264 0.418688 0.0722 R 0.523589 S C G S 0.051498 B

It follows that any format conversion would require a matrix recalculation. H.264/AVC takes advantage of the increases in processing power available from computer chips, but at the cost of more expensive equipment, both for the TV broadcaster and the consumer. As with MPEG-2, frames are compared for changes through comparing macroblocks of 16 16 pixels, but H.264/AVC also allows for comparisons of submacroblocks of pixel groups 16 8, 8 16, 8 8, 8 4, 4 8, and 4 4. At present it is not backward compatible with MPEG-2, which may present a problem with some high definition TV (see Sec. 16.13). 16.8 Forward Error Correction (FEC) Because of the highly compressed nature of the DBS signal, there is little redundancy in the information being transmitted, and bit errors affect the signal much more severely than they would in a noncompressed bit stream. As a result, FEC is a must. Concatenated coding is used (see Sec. 11.6). The outer code is a Reed-Solomon code that corrects for block errors, and the inner code is a convolution code that corrects for random errors. The inner decoder utilizes the Viterbi decoding algorithm. These FEC bits, of course, add overhead to the bit stream. Typically, for a

240-W transponder (see Sec. 16.3), the bit capacity of 40 Mb/s (see Sec. 16.5) may have a payload of 30 Mb/s and coding overheads of 10 Mb/s. The lower-power 120-W transponders require higher coding overheads to make up for the reduction in power and have a payload of 23 Mb/s and coding overheads of 17 Mb/s. More exact figures are given in Mead (2000) for DirecTV, where the overall code rates are given as 0.5896 for the 120-W transponder and 0.758 for the 240-W transponder. Mead (2000) has shown that with FEC there is a very rapid transition in BER for values of [Eb/N0] between 5.5 and 6 dB. For [Eb/N0] values greater than 6 dB, the BER is negligible, and for values less than 5.5 dB, the BER is high enough to render the system useless. The use of turbo codes, and LDPC codes (Sec. 11.11) currently being introduced for high definition TV will provide a much greater increase in transponder capacity. As mentioned in Sec. 11.11.1, the Digital Video Broadcast S2 standard (DVB-S2) employs LDPC as the inner code in its FEC arrangement (Breynaert, 2005, Yoshida, 2003), and the DVB-RCS plans to use turbo codes (talk Satellite, 2004).

16.9 The Home Receiver Outdoor Unit (ODU) The home receiver consists of two units an outdoor unit and an indoor unit. Commercial brochures refer to the complete receiver as an IRD. Figure 16.5 is a block schematic for the ODU. This will be seen to be similar to the outdoor unit shown in Fig. 8.1. The downlink signal, covering the frequency range 12.2 to 12.7 GHz, is focused by the antenna into the receive horn. The horn feeds into a polarizer that can be switched to pass either left-hand circular or right-hand circular polarized signals. The low-noise block that follows the polarizer contains a low-noise amplifier (LNA) and a downconverter. The function of the LNA is described in Sec. 12.5. The downconverter converts the 12.2- to 12.7-GHz band to 950 to 1450 MHz, a frequency range better suited to transmission through the connecting cable to the indoor unit. The antenna usually works with an offset feed (see Sec. 6.14), and a typical antenna structure is shown in Fig. 16.6. It is important that the antenna have an unobstructed view of the satellite cluster to which it is aligned. Alignment procedures are described in Sec. 3.2. The size of the antenna is a compromise among many factors but typically is around 18 in. (46 cm) in diameter. A small antenna is desirable for a number of reasons. Small antennas are less intrusive visually and also are less subject to wind loading. In manufacture, it is easier to control surface irregularities, which can cause a reduction in gain by scattering the signal energy. The reduction can be expressed as a function of the root-meansquare (rms) deviation of the surface, referred to an ideal parabolic surface.
