Digital video sender for Satellite/Cable

Why can't any of the Satellite and Cable box manufacturers make a digital
receiver which takes the raw MPEG-2 stream and instead of modulating it as
analogue via an RF modulator, modulates it using QAM so that it can be
transmitted wirelessly from the room the receiver is in to any other room in
the house.

If they did this the box and receiver would not cost any more than £30 extra
since the exiting RF modulators in STB's would only need an extra amplifier
and aerial to be added and tuned into preferably 5.8GHz so they are not
jammed by Microwave ovens and a remote control sender/receiver added. The
UHF modulators are already capable of phase modulation (QAM) because this is
what is used for colour in a composite video signal and they already have
the raw MPEG-2 stream which can just be heterodyned up or down to 5.8GHz and
received by a modified Freeview STB working at that frequency which can be
had for £20 these days.

The reciver boxes could be sold separately so that you can put one in every
room of your house and if the BBC, ITV, C4 and C5 are forced by OfCom to put
all of their channels on the same Satellite public service transponder just
like they are going to be forced to do on Freeview then if the entire
multiplex is transmitted from the Satellite or Cable box then anyone in any
room of the house can choose which public service channel to watch from the
modified Freeview STB using its own remote control.

In the old days of AM car radios you used to be able to get devices which
heterodyned SW radio so you could receive it on your AM radio and a similar
device could be made which took a 5.8GHz signal and heterodyned it to UHF
frequencies which would be passed through an aerial cable to any standard
Freeview box.

If the Satellite and Cable box manufacturers are not interested what are the
chances of success if I take this idea to Dragons Den? What kind of
development costs would be required?

Well it'd give us all a laugh watching you rant on-screen rather than
via usenet.

We definitely need some sort of digital video sender that can be used in the
same way as the analogue ones. One small box at each end of the link, and no
need to get involved with routers, wireless media centres or PCs and all the
unnecessary expense and complication that goes with them.

Dragon's Den is a non starter. They wouldn't know a good idea if it hit them
in the face, and there might as well be a law against designing or
manufacturing this kind of product in the UK anyway. Sadly, all we can do is
wait for someone in China to recognise the demand for this product, and
start manufacturing it there. It's a shame the Chinese don't read this
newsgroup.

I suppose you could submit the idea as a product suggestion to Maplin. They
must have contacts with Chinese manufacturers, and they might wake up to the
need for a digital video sender after a few years if you kept trying. It's a
shame no one at Maplin reads this newsgroup either.

Actually, the bloke who looks after the carpark at the Wombwell branch is an
avid reader.
