I thought Sirius TV have lease one whole 54MHz transponder from SES 12 at a "fixed price", no? Since the symbol rate would be 45000 already?
I know some backend, IRD box provided is H.264 like you mentioned in the previous post, but I believe Sirius TV can re-encode all channels into HEVC before deliver to viewers via SES 12 satellite, isn't it?
Cuz it would be somewhat a breakthrough to see a new pay TV provider uses only
HEVC video codec to deliver its content to viewers.
Because of the bandwidth savings, Sirius TV could have more number of HD channels than SD channels upon launch, which would makes it attractive to viewers...
Just my opinion...
Oh, how about the audio codec? Which one would Sirius TV plan to use? MP2? AAC-LC? Dolby AC3 or E-AC3?
At the moment with the Full transponder of 54 Mhz , bandwidth efficiency is far from our mind. As the subscription are free for 12 mths..it does not matter whether the channels are in HD or in SD. The customer just need a station without any commitment at the moment. The efficiency and the quality will slowly seep in as and when the customers numbers increased.
