    How many of you know this fact about HDTV?

    I am surprise that HDTV has been out for at least 8 years for the common consumer And still many people I speak with do not realize that you can receive HD broadcast via an standard old antenna (rabbit ears/old roof ant/powered ant) As long as you live in a city which has the capability(most U.S cities do), you can receive it to your HDTV. Today, just about every HDTV has a tuner built-in.
    So that said please post comments if you never knew or run into a lot of people that dont know.

    Thread moved to off topic from FAQ's. FAQ's are about car PC's.

    That said, I knew it but I know a lot of people who don't get it and can't understand it. They associate HDTV with cable or satellite TV.

    But at what level of HD are we talking about hear.

    SDTV is 480i

    the first level of HD technically was 480p

    I highly doubt that a standard output is capable of anthing over that.

    The higher the definition the more information transfered


    And not all HDTV's have a tuner built in. Many companies sell two models with and without tuners for the exact reason of people spending less on the tv without the tuner becuase they already have the box.

    I know when we got our new tuner from Directv they ran multiply different cables with certain filters in the line. This was done to allow the transfer of hundreds of HD channels. From that I'm only assuming that an old roof antena couldn't carry the info.

    1080p at fairly low compression actually takes less bandwidth than SD. About 10 years ago we were compressing a frame within the first field of an analog frame. That's why they can get hundreds of channels on a single satellite with only 24 transponders.

    The funny thing was those commercials with the converter boxes causing a big panic with people who already have digital cable and sat.

    How many people know that cable companies have to provide locals in HD at no extra charge and unencrypted?

    All TVs (since March 07) now come with ATSC tuners.

    Some TVs come with QAM tuners in addition to ATSC, which is what is needed for digital cable. But you will only receive unencrypted channels, unless you have a CableCard. The current gen of CableCard is only one-way, so you lose features, such as EPG and PPV.

    Generally you will receive a better HD signal over the air vs the cable. Format (480/720/1080) depends on what the station is transmitting.

    Autockr989,
    I haven’t seen an HDTV made in the past 2 years that did not include A HD TV tuner.
    ‘An HD TV tuner is for over the air only and has nothing to do with Digital cable TV ’
    ‘A cable card is for people who have digital cable TV and don’t want to use a digital cable box ”
    I am not talking about A cable (cable card) or satellite receiver built-in.

    Over the air is superior due to the fact that the band-width is not all used up like satellite and cable companies. They compress HDTV ever more due to the fact that they have hundreds of channels. I am not satisfied with HD by Comcast for fast moving scenes. Don’t get be wrong it looks great but not as good as it could. If you all have noticed that premium movie channels look better because the cable and satellite providers allow more band-width because you are paying a premium. To answer your question on the capability of coaxial cable what do you thing your HD cable channels are being sent by. The advance in coaxial over the year has ended up on RG-6 cable which is capable of 1080p 1080i 720p 480p…etc

    P.S Digital doesn’t mean HD and there is no such thing as an HD TV antenna ( all TV antenna’s are the same in principles)

    I think he is talking about HD-ready monitors.

    HDTVs always have an ATSC tuner. HDTV is either 720 or 1080. SDTV is 480.

    I have to agree with the OP and I think the people trying to steer the average joe to buying an 'HD Antenna' either get kickbacks from antenna companies or sell them themselves.

    I have a Panasonic TH-42PX80U here. Standard run-of-the-mill plasma HDTV with a built in QAM(Cable)/ATSC(Over-The-Air) tuner.

    Right now I have a cable DVR hooked up via HDMI and just an old RG59 'push-on' coax hooked to the built in tuner with one end stripped back to show the copper core and hung on a window behind the tv. Not even a proper antenna, but considering I live about 20 miles tops from the nearest antenna farm, it picks them up just fine. Get NBC in crystal clear high-bandwidth, artifact-free 1080i, CBS in 1080i, ABC in 720p, and PBS in wonderful 1080i.

    The people here are not giving enough credit towards OTA broadcasting. This digital conversion is actually providing the public a great service because you can get BEAUTIFUL quality pictures in full resolution HD that 99.99% of the time surpasses what cable and sat feed you because they don't have to worry about over-compressing the signal when sending it OTA. And in most places with even a half decent off-the-shelf antenna (which DOES NOT have to be branded an HD antenna. Any classic antenna will do. Even a pair of rabbit ears off a 70s-80s television) you can get dozens of channels OTA and then you have the sub-channels that many broadcast. Example being here we have the local WB station broadcast in crystal clear 480i SD alongside the local NBC station.

    Reiterating here: You do NOT need an 'HD antenna'. If you already have one be it simple rabbit ears, outdoor mast antenna, or just a hobbled together mess like my setup, it'll work depending on signal quality. And post-Feb, all these channels are gonna be going to full power digital broadcasting so with luck you can pull in channels just fine whereas before they could have been heavily clobbered with snow. This is another advantage to the digital conversion in that you don't need nearly as much power to differentiate between binary 1s and 0s in comparison to weeding out an analog picture from tons of snow.

    And unless you are looking strictly at HD 'Monitors', All HDTV's now have built in QAM/ATSC tuners. The big thing is most no longer offer cablecard access, but that's a whole nother topic.

    With that said, as an anecdote, if it wasn't for a few key cable-only channels missing, I would have made a complete switch to an OTA-only setup ages ago when I first got this tv. Could cut out about $80/mo around here. And most of said channels are blocked on the QAM side as well.
