    My son in law is about to take deliver of a new Sony 32W4000 TV. He is naturally anxious to see how it performs in HD, but does not at this stage intend taking out a subscription to Sky. However, he currently receives a number of Turkish stations by satellite, and some of them claim to be broadcasting in both SD and HD. Assuming that that is indeed the case, will it be possible for him to receive these stations in HD and, if so, what if any new hardware will he need to be able to facilitate that - although utterly ignorant of matters pertaining to HD, I'm assuming that some box or other would have to be fitted between the satellite dish and the TV.

    Any assistance would be most gratefully received.

    yeah Torper. a satellite receiver and dish (usually about 1.5 - 2 metres) pointed towards the satellite that broadcasts the Turkish channels. you may need a card too. HD is starting to appear everywhere now. but i am not aware of an HD and SD transmission on the same frequency. usually its a seperate transmission, as with Sky.

    It is possible for SD and HD channels to co-exist on the same transponder - as BBC HD does with BBC One Channel Islands and BBC One Cambridge on the same DVB-S transponder (and thus the same frequency).

    Luxe SD and Luxe HD are on the same DVB-S transponder at 28.2/5 as well.

    However this isn't good if the platform has a large number of HD streams - as it is better to use DVB-S2 for all-HD transponders if you can - as DVB-S2 gives more data bandwith on a given transponder as it is a newer modulation scheme that is more efficient.

    In the case of the BBC and Luxe they only have a single HD stream - and thus don't have the ability to use DVB-S2 (as they'd have to dedicate an entire transponder to one service and wouldn't be able to share with SD services - as all the SD receivers in widespread use in the UK are DVB-S only)
