Many new TVs have built-in Freeview decoders designed for DVB-T. Those of us with no line of sight to a transmitter have to use satellite. Rather than having to buy multiple DVB-S receivers, one for each TV, is it possible to manipulate the signal from the satellite LNB into a form that the TV decoders could use. The LNB presumably translates the satellite signal down to 1 (or so) GHz which is in the UHF range, but is the signal in a form that a TV-based decoder can handle? Perhaps there is scope for another block converter to move the group of transmissions into the band used for DVB-T. Any ideas?

Basically, No.

950 to 2150 isn't in the 518 to 806 range at all, single carrier QPSK isn't 8K carrier 64QAM and mpeg2 isn't H.264.

There are devices that will do what you want but they aren't cheap.
You'd be better to just have a stb at each tv.

I wonder if we will get TVs with DVB-S tuners in them?
Pretty sure they exist in other markets.

There have been a number of companies import and sell TV's with DVB-S tuners, just none that I'm aware of that are Freeview compliant with MHEG5. When you look at target market for such a product being 20% of the (already small) NZ population it makes very little sence to adapt a product to be compliant with Freeview.

Freeview certified TVs are all Freeview HD, which is received over UHF.

Freeview|HD terrestrial (DVB-T) covers 80% of the population, Freeview satellite (DVB-S) covers close to 100% of the population but the target market is only the 20% of the population that can't receive a Freeview|HD signal.

Have you seen/heard anything about freeview?  Not being rude, I'm just annoyed by the lack of easy/clear info out there about freeview. 

As mentioned above, freeview comes in 2 flavours and the best one is transmitted on land.  All freeview equipped TV's work with this UHF/land based/freeview HD service.

Satellite is the other flavour of freeview and it's intended for people outside the main coverage areas, who can't get freeview HD.  It does not have as good a picture as the land based version (no HD ability) and it does not offer surround sound either.

The revamped Freeview NZ site is about as basic but informative as it gets,

Real cheap.
Do they get the EPG?   Doesn't say anything about it in the TM listing.

I've installed a few of these - have had no problem with them. No EPG but hey, for $30 they're good value and can be hidden behind the tv, great for a wall mounted flatscreen.

What about remote control to change channels, how does that work?
