Hi everyone,
I'm new to HDTV. I just bought a Mitsubishi WS48313. Right now, I don't have an HDTV receiver. I connected my old Sony DVD via component cable and picture looks good. I was reading some post here that there are no difference between DVI connection and component connection. My first question is, how would I be able to take advantage of the 1080i resolution in DVD? Second question, if I subscribe to Dish Network's HDTV package, do they have to change my satellite dish in my roof? Do they have to change my existing receiver? Third question, I've read on some sites that local channels here in the US are already being broadcasted as HD. What antenna can you recommend and what receiver? I read some bad reviews on Terk 55.
Thanks for you help in advance.

I'll address a couple of your questions.
1. DVDs are not 1080i, they are 480i. Progressive scan DVD players deinterlace this signal to 480P. Some newer DVD players upconvert the signal to 720P or 1080i. Most TVs upconvert too, so whether you gain anything depends on the player, the connection and the type of TV (with fixed pixel displays gaining more than a CRT-based TV.
The component video connection you're using is just fine - see the FAQ on "Cables & Connections" - you may already have read the FAQ on DVI connections since you mention having read something on them.
2. For OTA signals, see the two FAQs on OTA and Antennae. Before others can assist you with choices, you'd have to provide your location.
3. Make sure you check out the FAQ "What you need to do to your new HDTV".

So how is the quality when DVD is upconverted to 720p or 1080i? Is it really fine/clear? Do you recommend this feature? What recommended DVD player support this kind of feature?
My Location is at Lake in the Hills, Illinois. I don't know if that helps. :)
I was searching for the FAQ on the last sentence you mentioned. I can't find it.
Thanks again.
if I subscribe to Dish Network's HDTV package, do they have to change my satellite dish in my roof? Do they have to change my existing receiver?
Yes and yes. Go to this part of the forum and skim the posts for info on the new SuperDish and the two new HD receivers (811 and 921):
http://www.hdtvoice.com/voice/forumdisplay.php?s=&forumid=414
The new SuperDish and the receivers are due out soon. We've been saying that for months now. If have Dish HD by the end of the year I'll be happy. (and surprised).
The 811 is a standard HD Sat/OTA receiver. The 921 is a three tuner unit with PVR (two sat tuners and a OTA).
Don't go for the 6000 receiver deal, old technology. That is my opinion of course, there are those who like the unit.
Third question, I've read on some sites that local channels here in the US are already being broadcasted as HD. What antenna can you recommend and what receiver? I read some bad reviews on Terk 55.
See my answer to your OTA question in you antenna post. Stay away from the Terk, my opinion again.
Here's the link to the 'What to do to your new HDTV'

Thanks again.
you might notice a slight difference, it won't be a big difference though.

So you are saying that a 1080i HD broadcast picture quality is far better than DVD even when upconverted to 1080i? Thanks.

yes. :cool:
A qualified yes. Some HD programmes have lousy production values and don't look much better than a good DVD, however, given equal (good) production values, the 1080i (HD broadcast) signal will beat an upconverted 480i signal quite handily.

Great!!! I can't wait to get an HD receiver. I have mitsubishi ws48313. Is this a good HDTV? :)

virtuosity (didn't feel like typing it letter for letter):
I just picked up the Mitsubishi 48413 and I love it so far (very similar to yours with a few minor upgrades). I've got the Comcast HD box - DVD's look great and the HD channels look superb.
FYI - another friend of mine who did much research also picked up the 55313 (same as yours, but 55").
Good choice in my opinion!

Going back to 1080i and our mitsubishi. I've read some article that there is another format, and that is 1080p. I think, my hdtv doesn't support this feature. Am I missing a lot? Thanks for the previous replies.
1. There are no HD signals available yet in 1080P format, only 720P and 1080i.
2. The only TV that can display 1080P is a very expensive LCoS TV by Toshiba.
You're not missing anything.

I just hope that Mitsubishi's Promise Module will support this in the future. Thanks for the reply.
The promise module has nothing to do with resolution. It's been a while since this was discussed, but I think the promise module contains digital connections and an ATSC tuner. Type "promise + module", without the quotes into the site's search engine. There are a few threads on the subject. Last I recall it was about $1k too...
2. The only TV that can display 1080P is a very expensive LCoS TV by Toshiba.
Are you sure about that? I haven't found it too hard to locate numerous models that claim to display 1080p. Besides, that toshiba was released in Jan.2003, you'd think some others would have come out within the last year.
I'm not sure, but it could just be a case of the advertisers putting something about 1080p, even though the tv really won't display in 1080p, but it might be able to take a 1080p signal and downconvert it.
Examples: http://www.hitachi.ca/product_list.asp?CID=103
I haven't found it too hard to locate numerous models that claim to display 1080p. Please provide substantiation.
The Hitachi video processing (upconversion) is done at 1080P on some of the better, newer models, but no display at 1080P.
Some Plasmas do 1080P, but they only have about 1000 pixels horizontally. Most plasmas do 768P x 1300 or so horizontally, which makes more sense.
Anyway, the point is. anything that's going to do 1080P natively is going to be very very expensive. There are probably some $25k front projectors that can handle 1080P and perhaps some other expensive equipment, but that's not what we're discussing here "for the consumer".

Hi 57u. I haven't done setups yet in HDTVs. On top of my head, this is what I came up with on connections regarding getting HD broadcast using outdoor antennas. Check out this link, http://restricted.dyndns.org/connection.gif
Let me know if the connections are correct. Thanks.
That looks fine, provided you don't need an amp or rotor. The amp would go between the STB & Antenna. I think you know about the rotor.
I don't know why you put this post in this particular thread - it probably should be over with the OTA stuff.

Sorry about the wrong location of post. Anyways, going back to the picture quality. My wife bought a cheap DVD player that supports progressive scan for my son. I connected it to my hdtv and tried the progressive scan. I didn't notice any difference between the quality of 480i and 480p. But pressing INFO on the remote shows a 480p on the screen. Anyways, could this mean that the player is a non-real progressive scanner? One information though, the quality on 480i is not too bad. Sitting 3 feet away from the unit, you can see that there is some smudging on lines (but not the red and blue). But if I sit 10 ft away, it's awesome. One more, I've read the whole manual and was trying to find the word 720. I didn't find it. Does it mean that my WS48313 doesn't support it? Are there any broadcast that are being sent at 720? Thanks again for all the good information.
Many people have noticed exactly what you point out - that they noticed no difference between 480i & 480P. This is probably more prevalent in the less expensive DVD players which do not do a good job of deinterlacing.
ABC and ESPN are broadcast at 720P. All STBs and integrated tuner TVs can receive these signals which can be converted to 1080i, like your Mits displays.

That's a great news. I am actually planning to buy an STB today. Best Buy is offering zer0 interest for 24 months. What STB can do you highly recommend? I will be using it first for ota broadcast. Thanks again.

The STB will convert all HD signals to one that your TV can display. Worry less enjoy more:D
