By providing a full postcode (such as W1A 1AA), national grid reference (for example SE123456) or latitude, longitude pair (like 54, -0.5) this page will provide a map, terrain plot and detailed information of the location showing the UK and RoI television transmitters that it is possible you receive Freeview, Freeview HD, Youview, BT TV and Saorview from.

(Don't know your postcode? Find it at Post Office Postcode finder).

UK Free TV uniquely shows you transmitter coverage maps, aerial to transmitter terrain plots, the closest 10 mobile phone masts (for possible 5G-at-800 interference) as well as tabulated information (sorted by direction, by received signal strength, by frequency, by service names or by transmitter name).

These predictions are based upon a rooftop aerial and depend on the suitability of the aerial, the distance to the transmitters, the power of their signals, the postcode area, and local terrain.

I think you will find that it is Pioneer/Sony and a few other bits of kit.
The affected Sony machines are Pioneer under the skin.

The actual 1.70 update has been running ok since it was made available in 2010.

Sony have said that Arqiva made a change to the EPG code?/information on Friday which seems to conflict with the affected machines (not all of which updated to the 1.70 version).

If, as has been suggested, the v1.70 software has been available since 2010 and only Sony equipment seems to be being affected, why was the reported change in EPG coding not tested properly? And why have no Pioneer owners reported the problem if they are identical? And why is it affecting users with the 1.65 version as well?
It is clearly not specific to one transmitter as the range of comments here, and on the BBC Technology website, are from widely differing areas but there is one common factor - Sony. The EPG coding may have been changed but it has not apparently affected any other makes - as far as we know.
Sony say, at last, that they are looking into it. I suspect their support phones will be red hot Monday morning. But if it's due to a change by Arqiva, why have Arqiva been so quiet?
I await clarification and developments from both organisations. It really is very poor for customer relations and is another example of poorly tested software and/or changes of coding.

MikeP: IMHO, Arqiva have nothing to do with this at all.

Arqiva own the transmitters in the UK, and they also own the COM5 and COM6 multiplexes.

But - they don't run the EPG. That is done by DMOL (now part of Digital UK).

The software update "channel" is provided by the DTG.

All "approved" Freeview equipment must play by the rules in the D-Book (aka Digital Terrestrial Television Requirements for Interoperability") from the DTG.

DTG have a testing facility though which ALL changes are put. I've been in the room and it's got every set-top box and digital TV ever made in it.

Even *IF* there were changes the the format of the EPG - something which is an international standard - it would NOT be rolled out on a Friday evening.

All changes happen on a Wednesday for a good reason.

I am reminded of the old anecdote that ends with "they are all matching out of step apart from our Johnny".

If the problem effects one piece of software on one box then Occam's Razor is all you need to deduce the source of the problem.

Briantist: Whilst there is the "unshavable" fact that this only affected one manufacturer's devices, is it possible that there was something erroneous in the EPG data (MHEG-5?)? I suppose the question is: when the broadcasters generate the data is it parsed for errors before being transmitted?

Is there a problem in the Woolwich area - have had no Freeview since about 1100 on 22 July - have reset BT Vision box twice as per guidance and still nothing, it says there is a fault in Bromley area could that be it? The message I get is Freeview signal low or poor quality. Any guidance wld be appreciated.

Over the last few weeks we have had interference (picture break up and loss of sound / picture altogether for several seconds) caused by aircraft - my postcode is LU1 4HY)
Until recently our picture quality was good apart from minor break up caused by boiler thermostat going on & off , using the paper shredder etc - which we can live with

Any advice most welcome
