cable channels conversion to hdtv channels

by manistee39 Sep 21, 2008 2:11AM PDT

I have Charter cable service in Michigan.

I have a Sharp LC-26sh12u TV and a Philips DVDR3575H/37 connected, in different rooms.

Both units have built in HDTV tuners. They are connected directly to the cable, no cable box.

HD Cable channels do not translate the same for each unit.

An example: Cable provides a digital music channel 903. On the sharp, this translates to channel 103.27, for the Philips, the channel is 103.41

Why would this happen?

A few things first off.

HD tuners are they OTA ATSC? Cable and OTA are very different.
There are far more channels available on cable than OTA, to access all the cable channels the TV has to have a built in cable tuner. How the channels end up numbered is up to the engineers that made the box. John

Tuners are OTA not cable. Carl

OTA means over-the-air...

which means connecting to an antenna. You TV probably have both atsc and qam tuner and it is built by a different company hence the difference in the number (I am just guessing here). I don't know if all QAM tuner has to be the same or not. Maybe not, hence the result you have.
