</div>Yea, they allow it now. In an update ratified in 2008. Care to guess<br>
when/if most sets being sold support it, better guess how many sets are<br>
in the field with only mpeg2 hardware? Now consider that over the air<br>
viewers aren't the most likely to chase the upgrade treadmill. Now you<br>
can make an educated guess when the first US broadcaster will feel brave<br>
enough to send out an h.264 stream and withstand the meltdown of their<br>
switchboard from irate viewers. And now you know the difference between<br>
standards on paper and defacto standards in deployment.<br>
<br>
Someday we will see secondary programs sent out in h.264 to cram a few<br>
more in, still wouldn't put a lot of money on it happening this decade<br>
though.<br>
<br></blockquote><div><br>One of the advantages of being in a market that adopted digital TV a little "late" I guess is that we didn't get stuck with mpeg2 - Terrestrial Freeview in NZ started on h.264 so we don't have the problem of a lot of people stuck with DVB-T boxes that support only mpeg2. Now practically every TV you buy has support for DVB-T and h.264 built in, as well as the STBs for people who bought before it all rolled out.<br>
<br>But I do see the problem with rolling out a change in technology in an established market.<br><br>They are turning off analogue here in the next year or so, the advertising is on TV, newspapers, the back of buses, billboards...<br>
<br>Unfortunately for us non-lovers of Rupert M, there is still a large perception that SkyTV is the only alternative :( Interesting times ahead, although I have my digital sorted thanks!<br><br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
