    Any reason to keep standard def channels if you have HD version? 1st Dec 17 at 2:52 AM
    Hi

    I am looking into getting a freesat box (ideally programmable to set the channel order).

    On the channel order I would like to put the HD channels in place of the standard def channels and perhaps even do away with the standard def channels altgoether.

    Is there any reason to keep the SD? IS hd unreliable during bad weather or something?

    Do away with Dave !! and Quest ! just to get a slightly sharper picture..no thanks.
    HD does not change at all for me whatever the weather throws at it, but I have Freeview not Freesat.
    IMO BBC s HD is nt as good as ITVS and Sky s is the best but they charge you a lot more a month for it.
    TVs vary a lot. I have the last of the Panasonic plasmas made and its better than any LCD display I ve seen

    BBC HD doesn't carry regional news and other regional items. I think for regional non news programs you end up with whatever London gets.

    Yes, how long can it take for the regional news to buy a few Hi Def cameras and update. Its been at least 7 years now having to switch from BBC on 101 to channal 1 at 6.30 pm to receive local news in dull old non HD.

    Anyway, I live in the Thames Valley North TV region but ITV 1 HD is Meridian East to get Meridian Thames Valley and Hampshire I have to select ITV 1 SD for local news and if wanted adverts.

    BBC 1 HD shows trailers not news during local news transmissions, local news is shown on BBC 1 SD.

    Thank you, so the BBC in general is a bit short of cash, no wonder with over 250,000 in court 2015/2016 accused of licence fiddling with most probably a couple of million others robbing the BBC of legitimate money getting away with it.
    Its not fair on the honest majority who are not thieves that so many are "evading "
    I really hope that some electronic method is established to rid us all for good of these thieves and stop it in its tracks

    Yet they put local news on the HD news channel, albeit in SD, but then you have to suffer the smaller pic/handsignals. So why can they just do that for the normal news?

    'BBC HD', the TV channel, is ancient history. BBC1 has local HD channels at least, and I think BBC2 does. BBC NI has news etc in HD (that's HD transmission, and HD cameras).

    The HD channels are on the same 'signal' as the SD ones, whatever way you receive them. If you don't get the HD ones, you're unlikely to get the SD ones. The HD ones use more bandwidth but are more efficiently encoded than the SD ones. Either way, it's the same ones and zeros being received.

    It would be nice to be able to reorder the channels and get the SD ones out of the way, and depending on your set top box, it's possible to an extent. Sky is very poor at doing this though, and about the best you can do is set up your list of 'Favourites'.

    The issue isn't a few HD cameras but everything from the cameras to the mixers, to the links from the studio to the transmitters and the transmitters themselves needs to be updated or altered, which costs a huge amount and in some case simply isn't possible

    From my understanding the BBC has been updating the regional/local studios but that still leaves the actual broadcast, and that leads to a bigger problem.

    There isn't (from memory) space on the transmitters to do HD for BBC regional/local channels. and the cost/space needed to do it over satellite and cable is extremely high as it would require something like another 14 HD channels that could be picked up by existing sets (when the next generation of receivers comes in and we switch over to better encoding that might change).

    IIRC we're still using MPEG2 for HD (certainly terrestrial DTV HD), which means that each HD channel takes up about the same amount of bandwidth as 4 SD channels, and there is a finite amount of bandwidth that can be used for each transmitter site without either clashing with other transmitters or being uneconomical to run as you need another transmitter (which is the reason some areas don't get the same number of channels as others, and some only get the "PSB" transmitter of BBC/ITV/C4/C5).

    This is the explanation from the BBC

    http://www.bbc.co.uk/programmes/articles/BbC4M14YmGHh8Vn52gp9d2/bbc-hd-channel-and-local-news

    The transmitters are all capable now of transmitting local news in HD, it's the distribution network as well as the studios that need upgrading.

    I think you're talking specifically about the transmitting satellite - my comment was general, across Freeview, cable and satellite - in that whether HD or SD, it's all just ones and zeros. The original questioner thought they needed a stronger signal for HD - whilst it needs more bandwidth, that's not really true.
