Re: technology vs. infrastructure the HD streams are unlimited until they move them from broadcast to switched digital video but that should not be a problem if they are monitering SDV usage at the tech operations center.
TWC can add more SDV QAMs to the pool or move a channel back to broadcast at&t cant do that they dont have a fixed broadcast architechure in place like cable does.
TWC started out 8 SDV QAMs and now are getting their divisions to add 8 more SDV QAMs to keep up with the HD channel explosion.
If the DOCSIS 3.0 gets congested and SDV has timeout errors they just splice in a new node which takes about a day to do.
TWC austin kept doing node split after node split when they were doing only 8 QAMs for SDV so they should not have as much problems until they get to 125-150HD channels switched at which point they can move more analogs to digital and rearrange and make those freed up spaces SDV QAMs they just did this with 5 analogs in janauary or do node splits again. but the statistics say 250 homes subscribed/passed per node is a good number for SDV as they have found that at all times about 40-50 channels are tuned to in a single node of course locals have to stay broadcast SD and Digital and so does the entire basic tier SD or they are violating FCC rules. |
