DVB-t2 is modulation
MPEG4 is video codec in MPEG2-TS (transport stream)
Ireland is/will be MPEG4 on DVB-t. UK is first to trial DVB-t2, about q3
2009 for MPEG4 HD.
The MPEG4 in Ireland is to roughly double the number channels at same
quality as MPEG2, for Standard Definition. There might be a HD channel
in the future.
MPEG4 is a separate issue from the resolution used.
There are absolutely no current plans for DVB-t2 in Ireland.
MHEG5 will be used for text and Interactive. It's unknown if the
extended EPG (one or 2 week rather than now & next) will use MHEG5 or
basic DVB. Either works. Not all DTT receivers and few PC sw
does MHEG5, though more available than the MHP or esp. the misnamed
"Open TV" used on Sky.
Freesat is an alternative to "Open TV" for Satellite for Program Guide
etc. It actually uses the same video streams as Sky Digibox. There are
rumours of PC SW for Freesat EPG soon.
