thanks, i understood that it cannot receive DVB-T2 but i was also wondering what the HD part of HDHomerun was for, as i understand, DVB-T is not broadcast in HD .. and the unit sold for the UK only receives DVB-T
I can understand the confusion over the use of HD for this product. As far as the UK is concerned it is impossible
for this product to do any form of HD.
In the UK we use the MPEG2 codec over DVB-T and currently only get SD resolution broadcasts. In theory it would be possible to broadcast and receive HD resolution broadcasts in MPEG2 over DVB-T but this would use so much bandwidth that we would loose room for a lot of existing channels. I believe that Australia did use MPEG2 over DVB-T for HD for at least a while.
Currently Ireland and Norway, and possible now also Australia, use H.264 over DVB-T for both SD and HD channels. H.264 is a lot more efficient than MPEG2 and makes this possible while still having a reasonable number of channels.
Here in the UK, the decision was made not to simply switch to H.264 over the existing DVB-T but to switch to DVB-T2 at the same time. DVB-T2 itself is more efficient than DVB-T and therefore the combined improvements of H.264 and DVB-T2 allow HD and more channels. This is exactly comparable with Sky HD here in the UK. When they introduced Sky HD they switched to DVB-S2 and H.264 at the same time for (most) of their HD channels and left the SD channels on DVB-S and MPEG2.
While currently DVB-T2 test broadcasts are taking place in the UK and supposedly will go live in at least some parts of the UK in time for the World Cup, there are currently as far as I can see no PC (or Mac) DVB-T2 tuner solutions. Indeed at this date there might not even be yet any stand-alone set-top boxes that can do DVB-T2 and of course no TVs with built-in DVB-T2.
I suspect some set-top boxes will be available in time for the World Cup but probably no Mac/PC tuners.
I would agree that ultimately SiliconDust need to upgrade their product to support DVB-T2, and likewise a new product that supports DVB-S and DVB-S2 is also needed. This DVB-T product does not need any updating for H.264 as that is merely passed through unaltered just like MPEG2 and handled by the PC/Mac and hence already suitable for Ireland etc.
While the UK is going to be the first country to use DVB-T2, it will not be the only one. On the DVB-S and DVB-S2 side, these are already widely used throughout Europe and the rest of the world and chips are widely available so there is no real excuse for SiliconDust to prevaricate over a DVB-S2 model. I would not be surprised if over Europe as a whole that DVB-S/DVB-S2 use exceeded DVB-T use.
Note: Elgato now have a new network DVB-T tuner which like the SilconDust product is also only DVB-T and not DVB-T2 compatible. It is probably a rebadged new Terratec product.
