Hi all. I just got Sky HDi installed the other day and I really like it but the channel selection really is quite poor.

Does anyone know why Sky doesnt have more HD channels available? Is it something to do with licensing?
 
The Aussie HD service Foxtel HD+ has BBC HD, Discovery HD, National Geographic HD, ESPN HD, a movie and another sport channel in HD.

Adding discovery & national geographic HD would make Sky HDi much more worth while.

Fellet is getting HD bandwidth FREE for 1 year from Optus. He wants to add (instead of putting Prime in HD) either Discovery or National Geographic in HD but also wants to simulcast the HD version in SD. Disc/NG won't agree as both have different SD feeds. All to do with keeping the service cheap unless they get large uptake of customers after 1 year.

EDIT: National Geographic HD/Discovery HD provision is dependent on 45 Mbps fibre feed from place of distribution, being Hong Kong/Singapore respectively.

And let's not forget probably the biggest reason we do not have more HD channels: Transponder space is limited, which also makes it expensive. HD obviously has much higher bandwidth requirements than SD, so for every HD channel you are broadcasting, that is about 3 SD channels you cant.

E!, MTV - And get your 1,2.3 and C4 feeds from freeview already. There is space for another 2 HD channels, not to mention the increase in SD quality for 1,2,3 and C4 seeing as Freeview use much higher bitrates and are on the same satellite.

They have 15 box office channels also. Hell, who even uses box office channels.

They only need 3 maxium.

There is heaps of crap they could axe and no one would miss.

Dont forget that the Foxtel HD movie channel is PPV only @ $7/movie.
So its not really in their HD tier, just OnDemand HD movies.  But understand the viewpoints on Lifestyle vs Movies in HD.

Does anyone know if the Foxtel Sports HD channel is 100% HD (or a mixture like NZ dependent on the native HD feed)?
Interested to know if they can use surplus capacity on the transponder to push HD movies down to the STB while the Sport channel is broadcasting in SD.  Or whether they broadcast 5 full channels in HD 24/7 - cant imagine they use capacity to push HD movies to the STB 24/7.

The Foxtel movie channel which is OnDemand PPV is run in non realtime, so has an effective bitrate probably not much more than a baseline SD channel.

I think Spyware is on the money (scuse the pun) regarding NatGeo/Discovery, but beyond Movies, Sport, and NatGeo/Discovery and the primetime stuff on TV1/2/3 you will quickly run out of HD stuff anyway.

For now. Hope they can conjure something up in a few years time when the availability of HD programming far exceeds what there is today.

I think its been well noted on other threads that Skys HD expansion will most likely happen on Optus D3 once its in service early next year.

That said I dont think there is an immediate capacity issue on D1 the current HD channels are on two muxs in TP10 which based on 8PSK 22500 FEC2/3 gives a usable payload of around 45Mb/s, and from all accounts the HD channels are running around 8-12Mb/s so thats 4HD channels per mux so one mux is only partially used at this time, and then there is another two muxs at TP9 to go, so thats potentially another 9-10HD channels before D1 is full (assuming no more SD expansion is needed).

So, my guess is it all comes down to money and the business case needed to put up more channels, not currently a technical limitation.

They are currently splitting the load at 3 HD channels per half transponder. I haven't been able to check the bitrates as I don't currently have a DVB-S2 card.
