In Reply to: RE: Is it HDMI or Time Warner - Update posted by Webnick on June 12, 2009 at 13:28:51
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.

That suggests that its a cable box/tv problem. Almost no delay when the cable box sends an (analog) signal via its own DA converter to the tv. But interminable delay when the cable box sends a digital signal to the tv via HDMI! Could my Mitsu DLP be the culprit? I know its been set up correctly for HDMI and the HDMI cables are the recommended type, so . . .?
Webnick:
Yes, your delay could be a result of HDMI handshaking issues between the set top box and the display which is why you aren't seeing it when you use component. It could also be the HDMI cable itself - they get bent, stepped on, etc. I would check out another HDMI cable (buy or borrow) and switch set top boxes with TW before I would conclude that it's your DLP... Good luck!
