Cable is only available in certain areas (mainly urban). Satellite requires you to have a dish and limits you to a fixed number of receivers, in that each receiver (TV, hard disc recorder etc) that wants to tune to a different channel needs a separate LNB at the dish, because satellite dishes unlike TV aerials don't supply the full spectrum of multiplexes simultaneously to the receiver. None of these are suitable for people who are mobile (canal boats, caravans) in areas of sparse population where there is no mobile coverage. |

And for boats, how precise does the alignment have to be, given that boats may drift or bob on their moorings? I only ask because even when we had satellite fitted at our house, it took the installer a long time to line the dish up correctly after he'd fitted it and the cables: he was up and down the ladder, tweaking it, for ages. It doesn't help that dishes are usually fitted so low down (not at chimney level) so they can't always see over neighbours' roofs. |

There is no theoretical limit to the number of satellite receivers. A box called a Multiswitch can feed many receivers from one 4-way LNB. http://en.wikipedia.org/wiki/Multiswitch I have three Freesat boxes. Two are recorders with two tuners each and the third is a single tuner non-recording box. They are fed from an 8-output multiswitch that has input from a 4-way LNB. That means there are 3 spare outputs. All the outputs from the multiswitch are independent of one another. One seller's website: http://www.satellitesuperstore.com/multiswitch.htm I understand that some multiswitches can be cascaded. None of these are suitable for people who are mobile (canal boats, caravans) in areas of sparse population where there is no mobile coverage. -- Peter Duncanson (in uk.tech.digital-tv) |

Well eventually they will get rid of terrestrial I suspect, but maybe they
will keep one channel for emergencies or something. The real snag with using sats as has been said is that its very much a fixed receiver thing. I know some ocean liners have it but not your average trawler! also, though, if the delivery is via radio waves from a mobile broadband system, that may well be made cheaper and hence as viable a as the current freeview. Who knows. If the sun cuts up rough in the next few years and trashes the sats, then what. Brian -- From the Sofa of Brian Gaff Reply address is active "NY" wrote in message ... wrote in message ...

It's a longer timescale than that, and they'll still be selling TV's. Manufacturers will simply be fitting the appropriate interfaces to ensure they can meet the upgrade/replacement market. Already internet connections are being introduced. It's likely that WiFi/UWB could be included to facilitate distribution of satellite-derived channels to multiple receivers around the home. |

You may think so, but in Germany they are *already* down to 10% terrestrial reception without any persuation whatever. Any spectrum changes will have to be consistent across Europe, and I doubt that the UK will be able to persuade other countries to retain spectrum for TV if they have no further use for it and want to switch over to broadband. |

My reading is that 470-694 MHz is expected to remain allocated to broadcasting for the foreseeable future, so I don't see it presaging the end of terrestrial television altogether. They can perhaps eventually release 694-790 MHz, for example by the increased use of SFNs and DVB-T2. Richard. http://www.rtrussell.co.uk/ |

That's exactly what I would argue.

Of course, it can be done, as we all know - point-to-point voice-over-IP and video-over-IP have been on the go for a long time, despite the poor match between the data (real time) and the medium (non-real-time). iPlayer is a great example of how well you can make that work, despite the unsuitability of the medium. If you throw enough spare non-real-time bandwidth at the problem, it works well enough to be effectively real-time. BUT - putting aside the theoretical niceties ("If we'd known you wanted broadcast, we'd have designed it differently,"), the fact is that the internet is all-pervasive and *will* do the job, even if it's a poor fit.

In practice if the Interweb becomes the medium of delivery surely two things will happen:- 1. Viewing will drop so dramatically that the broadcasters will loose so much income they will be unable to continue; 2. Most 'viewers' will probably still watch the same things at the same time as they always have. The great advantage of one-to-all - be it terrestrial or satellite fed - is that it gives structure to viewing which most people I would suggest find acceptable and/or preferable. OK now and again there is inconvenience that programmes clash or they are on when you are out (remember the one about the Irish VCR.....?) but surely that is why god invented VCRs and PVRs? Finally, much of this 'drive' for net viewing I would suggest is coming from personages resident within the M25 which gets all of the perks more quickly than anywhere else - higher speeds, FFTC and eventually FTTH, 4G etc - which are not easily available to the vast majority of the country and certainly not to those who live off the beaten track. Until such time as some system architecture is available that can give a clean uncontested feed of at the very least 2Mb to every home then I would suggest that net viewing will not take off to any serious extent and that existing methods will continue. -- Woody harrogate three at ntlworld dot com |

Even if I do watch nearly-live, I start watching late (if it's a programme on a channel with commercials) and then skip the commercials as I'm watching it on time-slip. I've probably not seen a commercial at normal speed for several years now. Any programmes that I've recorded to watch later, I pass through VideoReDo to remove the commercials and continuity spam, especially if it's a programme I want to keep in my library to watch again and again. |

You have to pay Sky at least £20. This is all completely wrong. People who don't want to subscribe to Sky are much better off getting a normal Freesat box. If they get a Freesat recorder they can watch their stash of programmes where there's no dish signal. A Sky box will only play back if it's getting permission from Sky all the time via the dish. This is important for boaters because it can save erecting the dish. Quote: "The biggest problem is that Sky program the digibox with the regional programs that are at the address where you had the card sent to!!" A Freesat box lets you alter the channel list by simply putting in a different post code. She says she has a 12V Sky box. Yes, these are available but often at a stupid price, and running them from the spike-infested 12V boat supply is asking for trouble. Far better to have a small inverter (ideally a pure sine wave one), then you can use any receiver or recorder you like. Most boats these days have an inverter anyway. A major howler: "Some dishes come with the correct angle set from the vertical…. … the first time you set up will take a little patience, but once that angle is set you will never have to change it again." yet she lists her travels as being all over the UK. The elevation angle varies very significantly across the country. Lining the dish up as described by means of a Skybox is a bit of a pantomime! No mention of the small cheap meters that are available, some of which now give the satellite ident. Bill |

Yes, these are available but often at a stupid price, and running them from the spike-infested 12V boat supply is asking for trouble. Far better to have a small inverter (ideally a pure sine wave one), then you can use any receiver or recorder you like. Most boats these days have an inverter anyway. A major howler: "Some dishes come with the correct angle set from the vertical…. … the first time you set up will take a little patience, but once that angle is set you will never have to change it again." yet she lists her travels as being all over the UK. The elevation angle varies very significantly across the country. Lining the dish up as described by means of a Skybox is a bit of a pantomime! No mention of the small cheap meters that are available, some of which now give the satellite ident. Bill Be gentle with her! Her blogs are very interesting and amusing. The problem is that the page was written pre Freesat, around 2003 I think, and she hasn't updated it. With a suggestion of how it should read, she probably will! Richard |

Yes but.... Actually I should have made something much clearer: if I were God I wouldn't use the internet for broadcast; I'd use satellite for broadcast and use the Internet for on-demand services. I really should have said that I understand the argument for freeing up the RF terrestrial spectrum, which you can do by providing broadcast services over the Internet or over satellite. And although the former will work, the latter makes much more sense. Without broadcast material the Internet will have lots more bandwidth for doing the stuff it is good at (delivery of user-specific services). I'm sorry for the last sentence in my previous post - in retrospect it doesn't properly reflect my views. Point for pedants: apparently we should always capitalise "Internet" because there's only one and it is a proper noun. And, of course, "Interweb" isn't a proper term (I know Woody knows that). I first heard it when Jools Holland kept saying it on his programme. Why does he think it "clever" or "cool" to deliberately flaunt his ignorance? On this topic, I'm amazed at how many people conflate "the web" (or "the World Wide Web) with "the Internet". Indeed, many people I've explained it to insist I'm wrong, and that "the web" is just another name for "the Internet". I've even heard people say that Tim Berners-Lee invented the Internet! -- SteveT |

If you were God you wouldn't need either. You'd just say "Let there be broadcast", and there would be broadcast, and you would see that it was good. And on the seventh day you'd rest, and watch some of the programmes, and realise it wasn't so good after all. Rod. |

We might return to the days of H aerials, X aerials and Band III Yagis, but with digital TV on VHF instead of 405 lines. VHF (especially Band 1) is not best suited to off-air multi-channel TV. For a start, Band 1 is very prone to long-range sporadic-E interference in the late spring and early summer. Even well before the advent of digital transmissions, many European countries had ceased TV on Band 1 because of such problems. Then there's the problem of designing aerials with sufficient bandwidth vs gain. OK, the Americans have such things, but they are generally used for the reception of relatively strong downtown transmissions. I'm not sure how good those used in Europe are (or used to be). I can't remember if (for example) Band 3 aerials, covering the whole of 175 to 230MHz, were very common. There are only eight or nine 8MHz VHF TV channels available (3 in Band 1 and 6 or 7 in Band 3) - and it would be extremely difficult comprehensively to provide the whole of UK with 6 digital MUXes in the same way as the two analogue channels were provided. At best, the full 6 MUXes could probably only be provided in well-separated centres of large populations. Elsewhere, the number of channels would have to be reduced. Although this is not dissimilar to what happens at present, I feel that the situation would be much more marked than we have at UHF. -- Ian |

With no ghosting to worry about and the ability of DTT to work with a low s/n ratio I should think the aerials would mostly be in the loft, and would be simple dual-band omni types. An SFN would probably be VP. Bill |

I don't think anyone would want to go back to TV in Band I for that very reason, however Band III would be suitable if the DAB channels could be recovered. Now *there's* an idea! |
