I've posted on the issue of MPEG4 enabled TV's in other related threads but got no response to my inquiries, so here goes here.
Freeview terrestrial tv (DVB-T) is as we all know being rolled out across Europe and the old analogue systems being switched off.
Countries which were early adopters (like the UK) of digital transmission embarked on the change-over using the most up to date technology of the time, MPEG2.
However, later countries are now using the newer MPEG4 technology and this means that unless televisions have both softwares installed they will be of limited use to those travelling to 'foreign lands'.
I have been trying to identify a TV manufactured for the leisure/commercial vehicle market which embodies both MPEG2 and MPEG4 decoding capability without success.
It now looks like we are now taking a step backwards in that there will by no longer a purpose built (leisure market) TV available those of us where MPEG4 is the standard and if we choose to purchase a 'house' television, when we tour in the UK area we will not have access to local television stations as an MPEG4 television (for Irish TV) will not work in the UK and visa verse for UK visitors to Ireland.
Perhaps RoadPro or one of the other major suppliers of televisions into the leisure market might consider installing MPEG4 decoding software in their products as an added value option.

I was under the impression that any TV that is capable of receiving Freeview HD in the UK is equipped with a DVB-T2 receiver to enable it to decode MPEG-4. Sony, for example, has a range of TV's that are capable of receiving Freeview HD and are equipped with both DVB-T and DVB-T2 receivers, so presumably they are capable of decoding both MPEG-2 and MPEG-4.
I also see a Philips TV spec that states "Digital TV: DVB-C MPEG2*, DVB-C MPEG4*, DVB-T MPEG2*, DVB-T MPEG4*, DVB-T2, Freeview HD". That would seem to imply that MPEG4 is not restricted to DVB-T receivers.
Reason for change by peribro: added mention of Philips TV
Any TV that can receive Canal+ Hd in France, or is compatible in Spain or the nordic countries will have MPEG4 enabled.
We have found that every TV that we have introduced to the UK market in the past two years has automatically been MPEG4 compatible. This includes the brands and OEM.
The only difference is with HD reception in the UK as we are currently the only country using DVB-T2. All other countries in Europe that have HD are using DVB-T.

MPEG2 & MPEG4 are compression formats for digital video data, afaik, so will be found in lots of hardwear which handles video.
Yes there are lots of TV's DVD players etc. which will decode both formats and much more besides available for the domestic market but they are primarily designed to sit on your sideboard, unshaken and unstirred.
My point is that I can't find any TV's purpose built to the standards of use/abuse relevant in the leisure/trucking market (like the products from RoadPro for example) on sale which include decoding capability for both formats. Which surprises me as that market caters for international use with exposure to both formats.

Gerry, I have inquired of both RoadPro and Cubik Products if their offerings are MPEG4 enabled, both have said 'no they only do MPEG2', which means their products will not receive the broadcasts you have mentioned, to which you can add Irish TV, when the owners of such product travel to those areas.

I have a fairly up to date Avtex TV.
It seemingly won't work in Ireland, I know it doesn't work in Norway and the manufacturers suggest it won't work in the Netherlands soon!!
I assume we will need a box for each country soon although we could spend a fortune on a satellite system

All of the Cello TVs sold by Cubik are MPEG4 compatible. We sell Cello TVs throughout Europe under various brands. Also, all of the currentLogik and Essentials LED TVs in Currys and PC World are 12V and MPEG4.

As MPEG4 is a later addition to MPEG2 any MPEG4 equipped device should be able to play MPEG2. That's laid down in the MPEG specs.
However it's unlikely to be as simple as that as it's not just an MPEG decoder that's needed and there could be any number of other factors affecting this issue.

This is very much not true.
Sweden has 2 DVB-T2 muxes 1 UHF 1 VHF, Finland has 3 VHF DVB-T2 muxes and 3 UHF DVB-T2 under construction most channels are pay. Italy has one pay VHF DVB-T2 mux. Czech Republic has several full power (50+ kW) DVB-T tests - Slovak is not far behind.
Denmarks will have one permanent DVB-T2 mux from April 2012, Austria will have one next year, too. Serbia will DSO directly to DVB-T2 April 2012.....
The order is Arial ---->Analogue tuner---->DVB-T/T2----->MPEG2/4 ---->Display.
DVB-T/T2 transmission is very independent of MPEG-2/4 video compression.
All UK D-Book requires the DVB-T2 devices also includes a MPEG-4 HD decoder chip - this is by convention.
All DVB-T2 chips can receive DVB-T too - but not the other way around.
All MPEG4 chips can decompress MPEG2 - "-"
MPEG2 chips can process SD or HD codeded (but HD not used in Europe)
MPEG4 chips can process SD and some also HD (High Profile Level 4.0)
