Auto Tuning Hdmi Cable Box

May 22, 2009 Switching from DVD Player to cable TV (HDMI inputs). I did auto-program the channels for the TV input early on, which was unnecessary and could be gotten rid of if there's a way, but I don't. Samsung smart TV - tuning issue? Spiidey Posts: 16,295. The only other appliances connected to the TV are a DVD player via HDMI (plugged into HDMI 1 socket) and USB hard disk box (connected to USB socket). Will get new HDMI cable and hopefully the problem will be solved.

If the thought of paying for cable or satellite TV service hurts your head, consider free over-the-air (OTA) HDTV. Nearly every household in America can tune into at least one HDTV station (99 percent of homes, according to some sources), and it’s absolutely free!

Researching free local HDTV channels

Spend a little bit of time researching broadcast HDTV channels. Now you don’t have to do this research online, but if you have Internet access, that’s the best way to do so. If you don’t have Internet access, talk to the retailers from whom you’re buying your HDTV — they probably have firsthand knowledge (or at least anecdotal information) about local HDTV signal availability. They may also have a kiosk that provides access to online information.

The Consumer Electronics Association (CEA) is the huge (and hugely influential) trade organization that includes just about every HDTV manufacturer in the world. So it has a vested interest in getting people to buy HDTVs. This interest is sometimes manifested as lobbying efforts with the FCC, or efforts to develop marketing and industry. It also pops its head up in the form direct-to-the-consumer education efforts.

In the case of HDTV, the CEA had the truly brilliant idea of providing an extremely easy-to-use HDTV “signal finder.” In conjunction with a company called Decisionmark, the CEA has created this online system (called TitanTV) that lets you enter your address information, press a button, and come out the other side with a nice listing of all your HDTV-channel choices.

Just go to TitanTV and follow the on-screen instructions. You can also access TitanTV at many HDTV retailers, and come home with a printout of your available stations.

Not only does TitanTV find OTA stations for you, it also comes up with the cable and satellite stations available to you. You can do a quick comparison and see what best meets your needs.

Tuning into the free HDTV channels

HDTV breaks the old TV paradigm in many ways. One big difference is that not all HDTVs have a built-in TV tuner. Back in the olden days of NTSC and analog TV, this was quite rare — a few high-end TVs were “monitors” and required an external tuner, but they were definitely in the minority.

With HDTV and OTA HDTV broadcasts, the situation has been reversed — at least for the time being (more on that soon). Many sets sold as HDTVs today are HDTV-ready, but don’t have any electronics inside them that can pick up an OTA HDTV broadcast — or any ATSC broadcast, whether high-definition or standard-definition. (ATSC is the acronym for the Advanced Technology Standards Committee, an international, non-profit organization that sets forth voluntary standards for digital television.)

The government is requiring TV manufacturers to include built-in tuners that can pick up OTA HDTV, starting with bigger (36+-inch) TVs in 2005. Soon this lack of tuners won’t be a problem.

Building on a built-in tuner

If you have an HDTV with a built-in ATSC tuner, you’re just about all set. All you need to do is find the appropriate antenna, make the connections, and go. It’s really that simple — or at least it can be.

Auto Tuning Hdmi Cable Box

Just follow the instructions in your HDTV’s manual for tuning in the HDTV stations. (Each HDTV on-screen setup process is different.)

Some HDTVs with built-in ATSC tuners also have special tuners that can decode QAM-encoded HDTV signals. QAM is the system used by most cable-TV networks. This means you may be able to pick up your local broadcast stations by just plugging in your cable TV connection. Note that this is different from the DCR (digital-cable-ready) systems. And no, this has nothing to do with using an OTA antenna, but it’s a nice morsel of information to know in case you’re ever asked this question at a neighborhood BBQ.

Adding on a tuner

If you own an HDTV, chances are good that you won’t have that built-in ATSC tuner mentioned in the previous section. Your HDTV probably has an NTSC tuner, which can pick up analog broadcasts, but it probably is only HDTV-ready, so you need to pick up an HDTV tuner box that you can connect between your antenna feed and your HDTV.

The biggest problem with HDTV tuners (whether they’re in your TV, or external) has traditionally been an economic one. They are (or at least were) darned expensive. Even a year or two ago, it was common to see HDTV tuners that cost $1,000 or more (this effectively explains why so many HDTVs were sold as HDTV-ready: Not everyone with an HDTV uses the OTA tuner, so why drive the cost of an already-expensive HDTV through the roof?).

The good news is that prices have come way down, which is common with consumer electronics. And the prices are going nowhere but down.

When you’re choosing an HDTV tuner, here are just a few things to consider:

  • Digital outputs: If it’s at all possible, you should use a digital cable connection between your tuner and your HDTV — either DVI-D or HDMI is by far the most common (1394/FireWire used to be common, but it’s rare these days). Make sure that the outputs of your tuner match the inputs of your HDTV.
  • The newer HDMI system is backward-compatible with DVI-D with the use of a simple adapter. So you can mix and match DVI-D and HDMI freely.

Auto Tuning Hdmi Cable Box Troubleshooting

    If your HDTV tuner’s DVI-D or HDMI output uses the HDCP copy-protection scheme, make sure the DVI-D or HDMI input on your HDTV does, too. Otherwise the system may weaken (or “down-res”) the signal, giving you a non-HDTV picture.
  • Analog outputs: While you’ll want to use your digital outputs, if possible, it’s handy to have a full set of analog outputs on the HDTV tuner, for making connections to other devices (like a digital video recorder).
  • Output resolution: Most HDTV tuners can be adjusted to match the best resolution for your HDTV. Some HDTVs require a specific signal resolution (such as 1080i); if yours does, make sure your tuner can give you output at that resolution.
  • Satellite capability: Some OTA HDTV tuners also include satellite-TV receivers. Well, the satellite companies would flip it around and say their receivers include OTA tuners. Either way, this can be handy if you’re using a satellite service for premium HDTV channels (like ESPN-HD and HBO) and using an antenna to pick up local HDTV channels.

The FCC is requiring TV manufacturers to begin including built-in ATSC tuners in their TVs, as part of the overall industry transition to digital TV. By the middle of 2005, all TVs larger than 36 inches will require an on-board ATSC tuner — over time, this requirement will filter down to smaller TVs, and even to devices like VCRs, which have their own NTSC tuners these days. (NTSC refers to the National Television System Committee, the group that sets television and video standards in the United States.)

Hi
New to this site so forgive me if I get the etiquette wrong - or post in the wrong forum.
I have VM V+ service and just last week took the plunge and bought a Sony Bravia LCD tv.
I also bought an HDMI cable from the local Sony Centre.
I connected the tv to the V+ box via both SCART and HDMI cables.
When first turning on the tv it said it would go through auto-tuning etc. I went through the steps but it came back saying it couldn't detect any services. (Via cable - I have no aerial)
However, I switched off and then when I switched on again lo and behold there was tv. All the regular VM channels.
However it isn't a great picture.
I've tried altering the settings on the V+ box to HDMI output (720 or 1080) and then rushing to change the settings on the tv to pick up the HDMI device but the tv says it doesn't detect any HDMI devices connected. The tv has 3 HDMI sockets but as far as I can tell it doesn't work with any of the 3.
I'm at a loss to know what I'm doing wrong and almost at the stage of sending the tv back to Amazon and claiming it's faulty.
Any help would be much appreciated.

    I have the same problem with my new LG LCD that I bought last week, however I also have a DVD recorder with an HMDI connection which works with no problem and have reported this on the Virgin support newsgroups suggesting that my V+ may be faulty, I'll let you know what they say.

    thanks jaykay - i must admit I haven't tried connecting anything else as yet. Just working on getting the tv sorted first! then worry about the other 'gadgets' i'd like to connect.....altho they are scart-only connections so wouldn't help me test the HDMI connection

    Initially setting up HDMI can be a bit tricky.
    Connect both Scart and HDMI.
    Once you have a picture via Scart -
    Go to Display Settings on the V+ box
    Change to HDMI, for a full HD set select 1080, otherwise choose 720 - it will ask you if you want to test this setting
    As soon as you hit OK you need to manually change your TV to the appropriate HDMI input.
    As long as you see the picture you can then confirm it as shown on screen. If you don't confirm the selection it will default back to SD mode.
    You can now disconnect the Scart cable if you wish.

    Thanks Brian
    As far as I am aware - that's what I am trying. But i'll have another go this evening.
    The instructions on the V+ box seem easy enough to follow and I get the window asking if i want to test the setting - it then seems to be when I try to alter the tv settings that the tv says it can't detect any HDMI devices and the pictures goes off.

    Though I normally use SD, I've tested my V+ on my Sony Bravia via HDMI and it worked ok, so it isn't a compatability issue. Maybe a dodgy cable/connection ?
  • #7
    Thanks Brian, i've already tried this but the problem in my case is that when I change to the HDMI input on my TV I get no signal & as I said before I know it's not my TV as my DVD recorder is working on the same HDMI input.

    When you switch to the HDMI setting (720 or 1080) on the V+ box and then confirm that you want to test the setting, a message will display only via the HDMI connection which asks you to press the TEXT button (bottom right?) on the remote if you can successfully see a picture. There is a fairly short timeout for this message so if you don't press TEXT in time (it's probably only a few seconds) then it will switch back to the non-HDMI setting which it had previously. This is probably what it is doing in your case.
    So you could try to:
    1.) switch the V+ setting to HDMI.
    2.) confirm that you want to test the setting.
    3.) quickly press the TEXT button on the remote to confirm that you want to keep the HDMI setting.
    4.) Switch your TV's input to the relevant HDMI channel and you should see the V+ channels coming through HDMI.
    The only downside to the above is that if for some reason the HDMI input really isn't working then the V+ box will be 'stuck' in HDMI mode and you won't be able to view the V+ through the SCART connection. However I remember seeing a previous message thread on this forum about how to reset the V+ picture settings back to their defaults via the buttons on the V+ box.

    Marker's suggestion is well worth trying. If you do not get a picture you can get back to SD (Scart) operation by the following :
    Hold down 'Play/Pause' and 'Stop' whilst pressing 'Reset' on the front of the box.
    This will boot the box into 'HD Wizard' mode.
    Then use FFWD and RWD to cycle through the various modes which will show on the display on the front of the box.
    Stop when you get to 'SD'. Press 'OK'
    Now reboot your box by pressing 'Reset' and it should boot back to Standard Def.
    regards

    Well the tech came today, not even 24 hours after it was reported..i'm still shocked at that! The result is he could not get it to work either and concluded that the box must have a faulty HDMI port.
    Thanks for everyone's help.

    I've got a bravia too, and I've had this problem since I signed up with Virgin over a year ago.
    I did a lot of web surfing when it didn't work.
    Virgin blamed the TV, Sony blamed Virgin.
    There's a few webpages on the web on some of the forums for it, but nobody ever solved it.
    If you ask me, Virgin are to Blame. Sony are one of the biggest tv producers in the world, I'm sure their HDMI support is up to spec.
    So yeah, I'm stuck without HDMI - which means no hi def movies on demand.
    If I could move to Sky I would but I'm still in my crappy virgin contract.
