Yes I know, like most countries in the world except the poorest countries
in Africa and Caribbeans. These are the same countries that also have
difficulty to transition their GSM mobile networks to except in dense
metropolitan areas. The same countries will prefer investing in G3 mobile
networks directly, or sen their programs to the satellite instead of
terrestrial broadcasts.

I already indicated it when I spoke about the cost of the transition (for
the media producers, for TC channel programmers, for broadcasting
infrastructures, and for customers): they have already paid several
transitions on the mobile network, and on the TV network, but this is still
not completely finished everywhere and the transition with dual networks is
extremeley costly for TV channels or on their own brodcast network.

In France, the free-to-air DVB.T started with MPEG2, now we also have MPEG4
for all the same channels in HD since a couple of years, plus a few
additional ones since the extinction of the analog terrestrial brodcast in
all regions (the transition from the former analog TV is terminated almost
everywhere except for extremely local areas with low power re-emitters, or
in private distribution by cable for some grouped housings (using a
transcoder for some channels), or still on historic cable networks. Even if
they are also transporting numeric channels and triple-pay
TV+Internet+phone, the cable operators still continue delivering the
historic analog channels in SECAM (PAL for some local channels of some
border regions) + DVB.T channels in MPEG2 + DVB.T HD channels in MPEG4 +
additional DVB.C subscription channels in MPEG4; sometimes this means that
some channels are delivered on 4 channels simultaneously on the cable !

In some areas the public regional network (France 3) is delivering the
regional programs of 2 or 3 regions simultaneously on the same DVB.T
broadcast, in MPEG2, on separate channels even if they are broadcasting the
same program in some hours, and so these few regional channels, which were
not converted to HD on DVB.T with MPEG2, are also in DVB.T HD with MPEG4 on
cable networks among all the regional channels). On ADSL Internet networks,
all these channels are available in SD and HD but they are not multiplexing
the bandwidth but selected on demand.

On mobile networks, they are available only in SD but encoded only with
MPEG4 (in a proprietary encrypted format based on H.264 AVC with
network-specific protocols requiring network-specific "boxes": these boxes
use proprietary extensions of generic Linux firmwares, these extensions are
definitely not open-sourced, you can rent this box or you can buy this box
from a single provider, the ISP itself, but you cannot use generic modems
except for the Intenet access only with online TVOD or VOIP services from
third parties (whose usage is blocked at the protocol level on mobile
Internet accesses, using slow HTTP(S)-only proxies over private NAT-ed IPv4
WANs but no full-IP connectivity) Not all channels are available on mobile
networks.

MPEG2 will still remain for some more years in parallel to MPEG4 in France,
at least with DVB.T over the air or with DVB.T and DVB.C on cable. There's
no space left for open/free codecs replacing the MPEG suite...

But on the satellite there's only one standard : MPEG everywhere
(preferably MPEG4 instead of MPEG2 because of enonomies on bandwidth, but
also because of encryption for limiting the region of reception, even if
there's no subscription, you have to buy a proprietary decoder card). The
way the European satellites are multiplexing the channels in the same base
channel also requires MPEG. Other open streaming envelope formats are not
supported.

So I really wonder how NZ customers will receive their programs on
satellite if it requires an MPEG decoder. May be the MPEG LA will create a
new version specific for use in New Zealand. I think that patent licences
on MPEG wil be replaced by licences on closed softwares plus contractual
requirements that customers must accept (without being able to choose the
hardware, so that the broadcaster will remain the owner of the terminal
equipments to rent with a subscription, so the open/free alternative will
be even more reduced than what it is today in NZ). This could also mean the
end of muliplay offersin NZ (with as many proprietary appliances or
terminals to rent as there are program providers or non-interoperable
access networks...), and an increased cost for customers.
