Re: HD Replacements When Olympics Are Over?
It's only a few weeks, some areas are using a temporary reserved frequency for these two HD's, but after they cease broadcasting, they will go back into 'reserved' state for future SDV or DOCSIS 3.
A lot of the frequency maps (whether currently occupied or NOT), are already reserved months in advance for certain services, or even as temporary migration slots for major QAM restructuring that cannot get done in one nights maintenance window. |

All that room and they are still shoving 3 HD channels into one QAM slot, interesting. |

| I suspect the 3:1 muxing, in cases where bandwidth is available, is a product of the fact that that is how those three channels are delivered to the local head-in, from the HITS. There are a lot of considerations, all the way through the delivery chain. |

1 edit | Could of fooled me, posting in the Comcast forums!
But I was going to say, you don't need HITS "Headend in the Sky" for 3:1. Much of that comes straight off the CRAN in multicast digital video streams pre-packaged and all ready to go. The headends just pick off the multicast and convert it to RF.
But if your TWC, that explains the *different* 3:1 muxes. VS Golf, History and USA together eh? Hows the quality? Wonder if they are using the Imagine Communications encoders over there at TWC.
Oh and I remember you said they upgraded to newer Motorola nodes? That's interesting, I would of thought TWC would pick Scientific Atlanta, exclusively. All TWC plant's I've seen use SA line gear. |

| we are the largest time warner market with all motorola equipment were getting the dcx boxes next year.
the picture on all my hd channels are decent we dont get the microblocking like the hits muxes.
we were comcast until august 1st 2006 when twc swapped markets with comcast
we did not get alot of channels until twc took over
cypher how long does it take to finish the upgrade after the reverse the spectrum analyzer. |
