Hello,
what is please the difference between latest NetTV and HbbTV ?

Once Philips-Service-Hotline told me :
2010-Flat-TVs with new NetTV firmware have the
new HbbTV-functions.

Another customer services member said:
HbbTV is not available in all current Philips-Flat-TVs.

My questions:
Have 2010/11 Flat-TVs with latest firmware (red button function)
also "full" HbbTV-function ?
or
When are PhilipsTVs available with full HbbTV ?
or
Is there a plan to upgrade 2010-models to full HbbTV ?
Thanks !!!
