Re: on board HDTV

what?! if its HD, then its broadcast digitally. and if has a digital tuner, it can receive high def broadcast also. so yes it is the same thing. a digital tuner in a tv gives you over the air Standard definition, and High definition, they are not seperate. it just depends on what the station sends out. and yes almost all tvs now have atsc tuners.

Sorry Homer... You are wrong... If it's HD, that does NOT mean it's broadcast digitally, that means it's broadcast (generally) in 720 or 1080 resolution. Has nothing to do with digital.

A NON digital tuner, also gave you standard and High Definition, they are NOT the same thing...

It DOES depend on what the station sends out..
An ANALOG station (pre-analog ban) can send out HD and NON-HD just the same as a Digital station can send out HD and NON-HD programming...

If you think just because you have a digital TV now you only get HD programming, you are among the many that need to do more research.

The only thing correct in your post is the last sentence...

There was never an an analog High Def standard adopted in the US. There was a system in Japan for awhile. There was never enough bandwidth to transmit an analog high def signal for the channel assignments in the US.

The analog NTSC standard can transmit only 262 lines in a frame. When interlaced it becomes 524. Thats all that can be handled with the given bandwidth. The actual effective number of lines because of Kell factoring is in the low 400s.

not ONCE did i say that digital broadcast means i get ONLY HD. i said , if it has a DIGITAL TUNER, (which pretty much every tv is now unless its a monitor or smaller) it is CAPABLE of receiving hi-def broadcast (obviously if tv is capable of displaying it). thats it, plain and simple. same thing. i have never seen a seperate tuner for digital, then one for high def as you are claiming. if your correct about that , please link a me a tv with a high def tuner, but no digital tuner.

i really dont know why you keep saying "being digital does not mean its HD" NOONE has stated that????? your arguing with yourself lol

also, never - ever heard of analog HD. if there is such a thing, its no more. so there is no point of even bringing it up?? seems to me, you were called out about being wrong, and your tryin to cover your butt ;)

Ok, and you PM me saying that we are basically saying the same thing, just differing symantics, then post this... And I'm the one starting a pissing match... :rolleyes:

While "technically" you're correct, they still started broadcasting "In HD" in 1998... Well before digital signal transmission. Now was it 720p? Hell no.. But it was still HD according to the broadcasters....

not ONCE did i say that digital broadcast means i get ONLY HD.
I don't know where I stated that you said that. I did say that if you think being all digital means all HD, you were wrong.
Actually, here's what you said.

what?! if its HD, then its broadcast digitally. and if has a digital tuner, it can receive high def broadcast also. so yes it is the same thing. a digital tuner in a tv gives you over the air Standard definition, and High definition, they are not seperate.

I said, being HD does not mean it has to be digital. Now to be "politacally correct", as Bruce stated, the HD we watched via analog broadcast was not 720, but the broadcasters still called it HD. We watched widescreen and were happy to call it HD...

i said , if it has a DIGITAL TUNER, (which pretty much every tv is now unless its a monitor or smaller) it is CAPABLE of receiving hi-def broadcast (obviously if tv is capable of displaying it). thats it, plain and simple. same thing. i have never seen a seperate tuner for digital, then one for high def as you are claiming. if your correct about that , please link a me a tv with a high def tuner, but no digital tuner.

You refered to HD and Digital, as "it's the same thing" in your previous post.. I said you were wrong, it's not the same thing.. I never stated a digital tuner was seperate from an HD tuner. If you can't follow your own posts then don't get involved..

i really dont know why you keep saying "being digital does not mean its HD" NOONE has stated that????? your arguing with yourself lol

Here's your qoute, smartass...

what?! if its HD, then its broadcast digitally. and if has a digital tuner, it can receive high def broadcast also. so yes it is the same thing.

Ohh wait... Isn't that you?? Saying it's the same thing?? Yea....

also, never - ever heard of analog HD. if there is such a thing, its no more. so there is no point of even bringing it up?? seems to me, you were called out about being wrong, and your tryin to cover your butt ;)

Analog HD IS no more, as ALL ANALOG is no more.. C'mon, keep up with current events..

Where was I called out? And where was I wrong?? Even FL_Richard agreed at one point, and we don't agree on much..

I said that being Digital doesn't make it HD, and being HD doesn't make it digital. The two are mutually exclusive (google that so you can keep up.) and that was about it. You come along and say that they are the same thing, then jump on me for saying they are not and accuse me of saying something about 2 seperate tuners for hd and digital..

Bruce is an engineer, so we will probably always have different language to say the same thing, but that doesn't change what the facts are..

Re: on board HDTV

I agreed that digital is digital and not necessarly digital HD.

(BS Alert) I've never heard of analog off air HD. I've never heard of it being commercially broadcast and have attended hi-end AV trade shows regularly for the last 12 years. You'd have thought someone would have brought it up in a booth somewhere.... But I'm sure it's technically possible.

WideGlide your a bit argumenitive. Take a pill.

Re: on board HDTV

Your conspiracy theory is just plain BS..



I didn't say they had highdef tuners, I said they have digital tuners...


im not goin to quote you on all your mishaps. ill just recap with one easy quote of yours. this is what lead to all this mess, and your fumbling attempt redeem yourself. but....


high def tuners are THE digital tuners.... that is where they are the same thing. sure, what is broadcast through it, may not necessarily be the same, but there is not seperate tuner for high def.... a tv has ONE tuner....period. its not rocket science :rolleyes:



thank you, and have a good day.

exactly, my point also... dont think he understands that..... for some odd reason he thinks we are stating ALL digital broadcast ARE in HD. not sure where he gets that from. maybe he is dyslexic, when i told him all HD is digital, he took that as all digital is hd? i dont know.

Re: on board HDTV

I just responded to your post homer that said HD and digital was the same thing. I also reposted it twice in my last post. Maybe you should read.
I don't know where you keep finding that I said tv's have a seperate tuner either.. The statement was to point out that just because a TV has a digital tuner, does not mean you are watching "HDTV". So you can stop saying that I said HD tuners are seperate.

I digress.. The exact reason I don't spend more time here.
This discussion didn't even involve you, until you injected your incorrect comment.

I may be argumenitive at this point richard. It gets iritating reiterating the same point over and over when people can't comprehend what's posted.

As for HD on analog, all I know is that I used to see "broadcast in HD" on many tv shows, years before the digital transition. Rather they were "HD" as we know it now I have no idea. That's not my view of it, that's what they stated...

Re: on board HDTV

The digital transition was scheduled and re-scheduled many times. The "Broadcast in HD and Available in HD" were tags identifying that the show was taped in HD. These HD shows were available in some markets through cable TV, usually test markets for digital cable systems. The show producers knew that HD was coming and they were the early adopters.

The digital transition was not the starting point for HD and digital, it was the finish line. Broadcasters had to broadcast digitally or be shut down. Many stations adopted digital years before the actual transition date. Most broadcasters simulcast in digital for early adopters with ATSC/QAM tuners and cable placement and also in analog for those off air watchers.

The shows recorded in HD were never broadcast in this country using NTSC as NTSC does not provide the bandwidth required for HD.

Look at this as in the old days when shows touted "available in color" while we were all watching black and white sets and the stations were upgrading for color.

Geez, now ya'll have made me forget what the topic of this post was. Oh, that's right...it was someone asking for an antenna recommendation for over-the-air signals wasn't it?

Re: on board HDTV

my tv power input is 12v, but it has an AC adapter in order to plug into a home 110v outlet. i want to replace that with a direct 12v cigarette style plug so i dont have to needlessly convert. anyone know exactly what i need to be aware of, to be sure i get the correct rated power cord, so i dont do any damage to my unit?

You might want to consider starting a new thread about that.
Not sure, but I think your TV needs 12 volts AC and a lighter recepticle puts out 12 volts DC.

ok, i might do that if i dont get an answer in here, figured i might not have to clutter with a new thread...

well the tv is 12v dc, the power cord converts into AC. but i dont need to convert to ac. no sense in converting to AC when im using it on a DC circuit. the tv is typically used in house, hence the reason it comes stock with an AC adapter, and not an auto plug.

Re: on board HDTV

The cig lighter is positive on the center contact. Just measure the voltage coming out of your adapter to see which one is the positive and wire accordingly.

Re: on board HDTV

WOW! there has been alot of flying crap here since I last looked in...... That theory was not mine and the point I was trying to make with the link was that the changeover had NOTHING to do with tv's not being available for the old signals but rather because with digital MUCH more info can be sent on the same bandwidth..... MY brand new 47" toshiba lcd has both analog and digital tuners.... I get several digital chanels and I still watch one station on analog
(28) when the digital broadcast of the same station (34-2) is garbled

The sad fact is this all started with a mistaken comment:

Any TV now will have a digital tuner. The whole reason for the switch-over was because there are no longer tv's made with an analog tuner.

The first part is mostly true although there are LOTS of old stock tv's out there with analog only tuners

The second part in red is just plain wrong by all counts and as a matter of fact most people with cable tv are still using analog tuners to recieve the signal from the cable company..... instead of lashing out and starting a huge fight just accept that you like the rest of us are human and make mistakes.... you can do a little google search and find all sorts of info on the subject ... Even the us government disagrees with you. Here is another link with no theorys to dispute....:rolleyes:

I hope I didn't start the crapstorm back up but maybe this info will be of use to you.

thanx bruce. but my problem isnt my 12v outlet (power point) thats already in and wired correctly. im tryin to find a power cord for my tv that is 12v dc direct (no house plug) basically the power cable that come out of my tv, will then plug into a round power point.
