I cant get SR-HD5 to work with cable

In this case, ATSC is referring to the modulation system used by over the air broadcasters for Digital TV (DTV), including HDTV. An HD DBS (satellite) set-top-box (STB) will receive both DBS and DTV. The Mitsu you bought falls into this category.


Cable uses a different modulation system for HD, called QAM. None of the DBS STB's have QAM capability. Most cableco's also encrypt HD signals (some do not encrypt local HD), and even a QAM tuner will not receive encrypted HDTV. To receive all cable HD channels, you'll need either a cable STB, or an HDTV or STB with CableCARD capability. The CableCARD is rented from the cableco and it allows you to receive all subscribed channels with your own equipment. CableCARD HDTV's & STB's also receive DTV.


There are some STB's with DTV and QAM capability. In addition to many currently available HDTV's, there are a few STB's with CableCARD capability. See the HDTV STB Synopsis for details.

Unfortunately, there are only a few choices for a STB's with QAM and/or CableCARD capability. Most units have been discontinued and are hard to find. Here is the link to the HDTV STB Synopsis: http://www.avsforum.com/avs-vb/showthread.php?t=179095

You should get analog cable, channels 2-99, whatever your local cableco offers, with the Mitsu. Maybe the Mitsu is not working properly?

Well I bought another receiver from radioshack today. Just search for the model nuimber at radioshack (I cant post a link until I have made 5 posts).


Accurian HTS 6000



Anyway, I put my cable into it and I set it to Cable STD input. Then it searches for channels and still doesn't find any. I dont understand what the problem is.


It says the signal strength on any channel is "48" and when i disconnect the cable, the signal strength decreases to "8"


I dont have a digital cable box and my provider is comcast cable. People in my area are getting some HDTV channels without digital cable and I just want to be able to do the same but it isn't working.


I also posted this as a separate post in the forum.


Please help



THANKS

Questi4110,


You're limited to OTA with the Accurian:


"The Accurian receiver is a low-profile design with a minimum of functionality, although it has all the right features and connectors. It’s designed to tune all ATSC-compliant (8VSB) digital TV channels, but will not receive analog (NTSC) signals, nor will it tune in unscrambled digital cable (QAM) programming. "

It's already been explained to you.


To get cable HD, you need a QAM or CableCARD tuner. The HTS 6000 is neither, just like the Mitsu you first tried.


Read the HDTV STB Synopsis.

Ok so I picked up another HDTV receiver with QAM capability from circuit city today:


Samsung SIR-T451


This time it did find channels in the 80s and 90s.


Some channels do look a lot more clear than others and it does look more clear than before I had the receiver. The channels are like 88-1, 88-2, 88-3, ...


All (maybe most, over 90%) do come in dolby digital (picked up by my surround sound receiver and shown on the bottom of the screen as "digital sound"). However, no channel seems to say HD in the top left corner. All say SD but some are much clearer than others.


Also, I am getting a lot more channels that I didn't have before (like HBO2 and a lot of music channels).


Am I seeing HDTV broadcast or just a clearer picture because I am using the DTV input on 1080i on my television?


THANKS

If you have a wide screen TV and have the view mode displaying side bars, it will be very obvious when you receive HD content as the picture will be displayed in wide screen. This should occur when Fox, NBC, CBS, ABC, PBS, and possibly WB and UPN are broadcasting HD content. Sometimes you will receive two or more channels from the same station (eg. PBS may be broadcasting on 5 channels) but only one of those is generally HD. In my area, generally the __.1 channels are the HD channels. All the other channels are just digital channels and not HD.


You can go to the following link to see what stations are broadcasting digital and a what times the channels are broadcasting HD. Unfortunately, this site only tells you the digital station numbers that are broadcast via air or the digital channels available when using a digital cable box for you area. Just enter your zip code and select digital broadcast to see the stations that are broadcasting via air. Although the channel numbers will be wrong (also you won't receive all those channels via cable), you should be able to see when the channels should be broadcasting with HD content.

Ok i figured out which channels are HD. Apparently the tuner didn't find these by itself so I had to put them in manually.


The game on CBS right now is in HD and it does fill up the whole screen so I dont think that side bars will tell you if it is HD or not.


Anyway, has anyone found an easier way to change frequencies directly on this unit (suppose I want 88-8) rather than just changing it to 88 which starts at 88-1 then hitting the channel up button? (I am talking about the SIR-T451)
