Recent TW tech change

Posted by mnilan on June 14, 2009 at 12:18:01:
Webnick:
As I understand it, TW has a new technical setup for dealing with many HD channels and limited bandwidth. Rather than send all HD channels to every cable box, they only send those that are being watched. So when you change channels, your set top box sends a signal to TW telling them which HD channel to send your TV. If someone on your block is also watching that channel, then it will come in on your Tv immediately. Otherwise, it takes 30 seconds or so for the signal to get changed at the TW end and get back to your TV. In my area, this technology was implemented in January but in your area, it could have been more recent. At any rate, some additional delay is "normal" now.
