One of my TV's I watch thru Microsoft Media Center (The computer) via QAM. Are these channels that were once available as an analog channel thru QAM now available as an HD channel thru QAM
TV's will still be able to pick up the analog channels. There are very few left, mostly locals. The transition involves moving many of the heretofore analog channels to digital. This does not make them HD; they are still SD only in digital. They may or may not be able to be picked by a QAM tuner. Comcast is in a transition to restructure its digital TV distribution system. No one can be sure what channels will be available in the future via the QAM tuner. Certainly the locals (SD and HD); but beyond that, only time will tell.
The web site below keeps track of the QAM channels, but whether it is up to date with the latest changes to the Comcast line-up is unknown.http://www.silicondust.com/hdhomerun...236#sidebyside
I should also note that, although the Comcast notification information indicates that the digital adapter will only pick up channels below 100, I went through the channels and mine picks up quite few above 100. No HD of course.
There are two set-ups that can be used to get both the channels picked up by the digital adapter and those picked up by the QAM tuner. However, it takes the right equipment and some patience. However, it only works for watching and not recording with non-Comcast DVRs.
First Set-up: You need a cable splitter. Also, the TV must have separate inputs for over the air and cable signals and the TV remote should have button to switch from air to cable inputs. Split the cable signal and make one connection from the splitter to the cable input on the TV. The other connection goes from the splitter through the adapter to the air input on the TV. When selecting the "air" input on the TV, the channel should be on the adapter output channel and the adapter remote is used to select the desired channel. When selecting the "cable" input on the TV, the desired QAM tuner channel can be selected using the TV remote. This works; I have tried it.
Second Set-up: You need a cable splitter and an antenna A-B switch. In this case, the TV need have only one input for the cable signal. Split the cable signal from the wall and make one connection from the splitter to A input of the antenna switch. The other connection goes from the splitter through the adapter to the B input of the antenna switch. The output of the antenna switch goes to the signal input on the TV. Use the antenna switch to choose whether to get the straight signal from the cable provider which would provide the QAM unencrypted channels (switch A) or get the decoded signal from the adapter (switch B). When receiving the signal through the adapter, the TV channel should be on the adapter output channel and the adapter remote is used to select the desired channel. When receiving the signal straight from the cable provider, the desired QAM tuner channel can be selected using the TV remote. I have not tried this but would seem to be workable.
