Re: More channels crammed in
said by acs12798  :Hooray, we get more channels....now we can have every HD channel crammed with 3 more per QAM. Do they have the bandwidth available, or will quality have to be compromised? |

Do they have the bandwidth available, or will quality have to be compromised? If you look at lyngesat, many channels are already 3 per transponder anyway from the satellite. Some cable providers even have to pad their QAMs with extra bits to fill up the extra space.
So don't think that 3 per QAM automatically means "worse than FiOS" because FiOS gets it from the same place. |

This has been discussed at length in the AV science forums, and it did appear that my Comcast picture quality was reduced on those channels grouped 3 per QAM. I agree it does not automatically mean the quality is inferior, but it is more prevalent when the signal is recompressed and not simply passed without any modification. |

| Comcast is taking the feeds from the sats that are less than 3 per QAM and cramming them in 3 per QAM.
I can understand why you are bitter towards Comcrap, but they are not reflective of all cable providers.
But many cable providers are in fact passing along the signal as received, even if they are 3 per QAM, because they are received 3 per transponder on the satellite. |
