Sep 2008 at 13:43 I was out with my eldest brother the other day in his heap of poo X5, and it dawned on me... ...when the analogue TV gets turned off, will in car TVs die a death (obviously the analogue ones will) - will they make digital ones, ie is it possible to make a good enough aerial for in car TVs?

All car aerials will be wideband anyway (all thats required for digital), the question I was posing was could a car aerial be powerful enough and selective enough?

Seeing the signal qauilty of TV's in BMW 7 series, chances are low Undecided

Digital TV receivers for in car use have been on sale for a good few years now - (keep up !! Roll Eyes

)

Mixed feelings about them personally as the reception seems to be poorer than the analogue when going along. At least when the analogue signal dropped out the picture went fuzzy but was still tolerable, the digital one just goes blank or covers the screen in squares. Most annoying.

If you intend to put something in a car, don`t bother with a TV tuner at all, stick with DVD and if you want something for a caravan, or RV its cheaper these days to use a mobile sattellite receiver and dish, as they are now available for around the £100 mark.

Never had a problem with Freeview - I use a PVR as well

I think at the moment it could be difficult to get a decent signal. It's marginal from a rooftop antenna with 15db gain or more in places, after all. Might improve as stated when the analogue carriers are removed from the equation and the transmitters can be driven harder on the digital carriers.

The other factor to consider is multipath. DTV was designed for static viewing. Using it in a car introdues a lot more multipath which will really screw up the bit error rate if, as I suspect, the equalisation in the receiver isn't up to coping with it.

That means watching it on the move would be a problem (why would you?) but also watching it when parked up in a city full of tall buildings or by a road with moving traffic. That's not going to be resolved by stronger signals. It's something the modulation and channel coding of the signal wasn't designed to cope with.

Why would you? I think something to do with keeping the little cherubs on the back seat quiet rather than the old fasioned method of communicating with them, playing I-Spy, or even the excellent method of keeping kids quiet in my day - thumping them very hard.

I take your point about the signals though - Thumbs Up!

Amazing really, we tell the parents the signal will be crap, but still they won`t listen and keep paying us extortionate money to fit them, and then moan about it afterwards.

OK. Point taken. Embarrassed

Guess who hasn't got any "little cherubs"? Wink

It's the problem we face with all these digital standards. As they are optimised to a greater extent, their range of application narrows to the point where you need a new standard for every application.

Maybe DVB-H or MediaFLO will eventually provide the answer. I must admit, I never appreciated the point of TV on a mobile phone, but to the back seat of a car on a long journey maybe it has its merits.
