11. This is a big improvement but you still need a rather solid support for that But how to compare the performance of Luneberg lens antenna to the traditional dish Well made lens can have the gain per formance close to the theoretical maximum for the aperture size And indeed the com parison of the published specifications shows Circular LNBs GT SCIR40 GT TCIR40 GT QDCIR40 that Luneberg lens of a given diameter has only slightly smaller gain than the offset dish of the same size For example 50 cm lens will perform similarly to 50 cm offset dish In small Luneberg lens you cannot use typical LNBF s to receive satellites which are 3 or 6 apart You will need narrow profile LNBF s or you will have to choose the satel lites which are more distant Simple calcula tion shows that if you have 40 cm Luneberg lens and 7 cm wide LNB s which are located 1 25 R from the lens center i e 50 cm you can not receive 2 satellites that are closer than 8 Moreover a typical LNBF viewing angle is intentionally made rather sharp to avoid picking noise from outside of the dish If you return to figure 3 you will see that in this case the rays are coming from a wide angle So we can say that to achieve maximum performance of a Luneberg lens antenna one must carefully select the right LNBF s Conclusions Contemporary Luneberg lenses are lighter and much cheaper than their predecessors They are still not so easy to manu

Because the EBU never changes FEC or symbol rate clever people created an extra satellite entry in the receiver with just the EBU feed transponders and after performing a satellite scan they can channel surf through all the currently active EBU feeds The signal quality on the EBU feed transpond ers when compared to other end user signals is excellent Thatis really no surprise considering that the EBU uses bitrates from 4 to 10 Mb sec If you perform a direct comparison of studio produced material of course analogue trans missions would have the best video quality it s quality equals about 210 Mb sec but right behind it are MPEG 4 2 2 signals with about 10 Mb sec It s clear sharp has great colors and even high speed action does not affect the perfect quality The quality of the digital signal for the end user however is quite the opposite it has a foggy look to it and the colors are not nearly as brilliant This of course is no surprise since most broadcasters use bitrates that are about 3 Mb sec or less In the end we are convinced that now is the ideal time to get in touch with MPEG 4 2 2 The receivers are very cheap and the video quality is out MM Ts Quali HDTV receiver showing a feed in MPEG 4 2 2 standing 49 www TELl satellite com TELE satellite International Exhibition Preview 28 30 September 2006 SatExpo 2006 Space and Advanced Telecommunications Vicenza Trade Fair Vicenza I

24. ago when MPEG 2 systems were quite new some video related problems were arising due to the first generation MPEG 2 processors used in those days receivers If you have a very old set top box some of your video problems may have such origin Software upgrade may sometimes help if still available By the way it is very interesting if a similar situ ation will happen again with the first generation of MPEG 4 processors After all they are made by humans Conclusion Although there are potentially many factors that influence the quality of video in digital TV the two most important ones are the picture resolution and the compression level used by the provider When you want to asses the video quality of your system especially with the beau tiful brand new high resolution flat panel TV choose wisely the channel on which you do the evaluation Visit www satcodx com and select the channel that has the highest resolution 720 704x576 for PAL or 720 704x480 for NTSC and the highest bit rate which means small loss of information and small distortion during MPEG 2 compression Perhaps we could even formulate a rule of thumb for what we can expect depending on the bit rate Assuming the maximum resolution for a dynamic channel sports movie we should get the following video quality excellent for 5 Mb sec very good for 4 5 Ms sec good for 3 4 Ms sec fair for 2 3 Ms s and poor for less than 2 Ms sec Www TELE satellite c
