No. Digital sets are the most likely, and there are different digital systems which require a different sty;e of tuner.

What is a built-in ntsc atsc qam digital tuner?
An NTSC/ATSC/QAM digital tuner, in the case of a TV, means that the TV supports the NTSC, ATSC, and QAM broadcast standards with its included tuner. NTSC is the old analog over-the-air (OTA) standard, ATSC is the newer digital over-the-air supporting High Definition video and Dolby Digital AC3 audio, and QAM means that the TV can decode digital cable signals without a set-top box. My internet research indicates that QAM will receive unencrypted broadcasts only. While encrypted channels varies by geography, it seems that most cable stations are encrypted while major networks are not. So, best I've determined, is that if you want more than just the major networks in high def you still need the set-top box or Cablecard.
What is needed to tune into HD channels?
To tune into HD channels there a a variety of methods available to consumers. These include a digital set top box, a digital antenna, a satellite receiver or a QAM tuner built into the television.
Can a sharp lcd tv receive digital broadcasts?
You can find anything you want on the internet. If you had provided the Model Number of your television, we could have helped you by googling your TV's model number, etc. Therefore, we have to be more general. Generally, the answer depends on one thing -- does the TV have a DTV [digital television] tuner. It is possible that an older LCD television has only an analog tuner, which would make it the same as an old, traditional TV except for the TV screen. The manual might say "Digital Ready," which is a marketing term used by such old LCD televisions. Un-abbreviated, Digital Ready means that you have to add a DTV tuner. At the time these TVs were made, there were no DTV tuners, so you were preparing for the future. Today, yesterday's future is now. The $40 government coupons can be put towards a digital TV set-top box that is a digital TV tuner. All convert the digital signals from an antenna to analog outputs on Channel 3 or 4, which you can connect to your TV with a coax cable, and then tune your TV to Channel 3 or 4. The $40 to $60 set-top boxes take a perfectly high-resolution digital TV signal, and convert it to an old fashioned, mundane analog TV signal. Boxes in this price range (and all that are covered by the coupon) do NOT offer a digital output, which would offer advantages like improved clarity and higher resolution (more and finer lines that compose the picture). If that were my situation, I would find out the maximum resolution my digital-ready TV were capable of displaying (such as 720 or 1080 lines) and I would make sure I got a set-top box whose output [to the television] [numerically] matches the TVs resolution. That will mean something NOT covered by the coupon program, and much more costly. If you want to watch digital TV is all its glory, it will be worth it. Newer LCD TVs that include [internal] digital tuners will have manuals that mention "Tuner: NTSC, ATSC, QAM." These are true DTVs [Digital Televisions]. Interpretation: NTSC is old-fashioned analog; ATSC is the new, free, over-the-air-to-your-antenna digital broadcasts, and QAM is an unscrambled Cable-TV signal. Regarding QAM, you would only be able to take advantage of the QAM capabilities of a digital television if you have Cable TV service. In that case, you might stick the Cable into your digital television, and see if your Cable TV company is delivering any unscrambled QAM signals that a digital TV can receive, direct off the cable without a Cable TV box. However, for the purposes of this conversation, your question about digital broadcasts, we're mostly intereseted in ATSC. If your television's manual says your television has a DTV tuner, then all you have to do is figure out how to switch your TV from its Analog tuner to its Digital tuner. That will be just a few clicks of the remote control to switch to the Digital tuner, and then another couple of clicks to get your TV to "search" for digital TV signals [perhaps called "Autotune"] -- where the TV goes through the whole TV band and "saves" digital TV channels that it detects. When the search procedure is completed, you can just hit the Channel Up or Channel Down buttons to scroll through the saved channels. And, if you don't have the manual for your television anymore, then get the Model Number from some tag glued to your TV in a hidden location. Google the Model Number; maybe the manual is available as a free download, or is at least available for a few bucks. Also, perhaps now that you have an idea what functions you're looking for in your TV, you might not need a manual to determine whether your TV has a digital tuner or not. Does Autotune only find Analog signals? If you switch the "input" to Digital TV, does that lead you to an Autotune for digital signals? or only a dead-end? Best luck, -Neil-
What are the three modulation techniques used for digital television transmission?
Three different modulating techniques are emploed to provide digital television (i.e. satellite, cable, UHF ) and these are known as DQPSK, QAM and COFDM. Each technique is a variation of phase modulation. QAM also takes advantage of amplitude as well as phase changes.
Do you need cable box for HD tv?
If you mean free Over the Air (OTA) TV using an antenna: 1) If you have an HD TV set, you don't need any kind of special box. 2) If you don't have an HD TV set, but your TV set has a digital tuner, you don't need a special box, but you will see the HD picture converted to a Standard Definition (SD) picture. 3) If you don't have an HD TV set and your TV set does not have a digital tuner, you will need a converter box. The converter box will convert the HD broadcasts to SD so your TV can display them. If you mean cable TV, it depends on your cable provider and your TV. If you don't have an HD TV, at best you will see an HD signal converted to SD. If your TV has a digital tuner and it is also a QAM tuner, you might be able to receive some HD channels without a box if your cable company chooses to provide unscrambled HD channels. If your TV has an analog tuner or a digital tuner without QAM, you will need some sort of box.
What is the function of a TV Tuner Box?
There are several scenarios for using an externa TV tuner box. The first is if the Tuner box has a coax output (for channel 3 or 4) and the TV can be tuned to that channel it can be used in place of the TVs internal tuner. An example is if the UHF tuner is out (channels 14-69) it can be used to receive those channels. If the TV tuners VHF (2-13) and UHF (14-69) are out and the TV has an AV input (yellow-white and or red) the TV tuner box can be used to receive the antenna channels. Similarly the TV tuner box can usually also be set to receive cable TV channels by changing a switch on the box or changing a setting in a setup screen on the TV tuner box. The second instance (and this will become more important as we near the FCC analog signal cutoff date of Feb 17, 2009). All analog signals will be cut off on that date. Older TVs that do not also have the ATSC or QAM tuners in them will not receive antenna or digital cable signals. Many TVs sold after around May 2006 to present have those tuners built in. Virtually all HDTVs sold after that time will have them. The TV tuner boxes are available now, but generally are in the $150.00 - $200.00 price range. As we get closer to January 2008 we will see more of these offered in the market and will likely be much less expensive $40.00 - $50.00 range. The Federal Government has a program for issuing $40.00 vouchers for such TV tuner boxes and each family will be alloted up to two. Many consumer electronics shops and stores will have the boxes and be able to redeem the vouchers.
Can you buy your own box to receive the HD TV signal if you have just purchased a HD TV and have not signed up for HD TV service from your cable company yet?
Please note that you don't have to have HD TV service to play HD TV games, but you do to watch high definition television. If your TV is an "HDTV" (as opposed to a "HD ready TV"), then the Radio Shack box isn't going to do you any good. There are two ways that you might be able to get HDTV programing without buying HD cable service. Your HDTV should have a digtial over the air tuner (ATSC in the US). If you are located in an area were you can get TV reception with an antenna, then just hook up a TV antenna to your HDTV and tune into a HDTV broadcast. Some cable systems include non-premium digial channels in a format called QAM. Most HDTVs have a QAM tuner built into them. Just connect your HDTV directly to your cable outlet (not through a converter box) and scan for digital cable channels.
