Guys,
I know 1080p is the best source of HD you can get...but i was just wondering if anyone knew what 1080i is like? Is it any better than standard DVD viewing with regards to picture quality and sound etc? Would i be able to see and hear the difference??
I'm looking at getting a 1080i upscalling dvd player. A quick fix really until i can get a Blu Ray player. The standard DVD player i have at the moment is rubbish, so i'm just looking for something better.
Also, does anybody know if all upscalling dvd players give the same amount of upscalling...or do some do it more than others?
Cheers
Craig.
wow that left me behind!
i'm still on vhs

1080p is progressive scan where as 1080i is interlaced. With progressive scan each 'line' of picture information is processed sequentially, with interlaced all the even number lines are scanned then all the odd number lines to fill in the gaps. This was a feature required for CRT displays to reduce the amount of flicker at the standard 25 frames per second rate, it meant you could double the frame refresh rate to 50 frames per second with only 25 frames of picture information.
So what you are getting with the upscaling is two identical lines next to each other and hence half the vertical resolution. So you could say an upscaled signal on a 1080i screen would give the same quality as 540p.
I have upsacling DVD player through Full HD 46" LCD. TBH you don't notice that much of a difference over regular DVD. I have a film to get on my BT vision this week that is available on Full HD so I'll compare it to an upscaled picture and tell you if I think there is much between both of those.
If you get a half decent sound system with 5.1 unless you are right film buff I am sure that would suffice to watch your films.

Thanks for your reply's people.
I actually bought a Toshiba HDMI 1080p upscaling dvd player last night. The exact model is TOSHIBA SD480EKTB.
It only cost me £50 and i must say, there is no comparison in picture and sound quality compared to regular dvd players! The picture is alot clearer...even on 1080i. It's running on a 42" Philips Flat LCD TV. Unfortunately, last night i found out that the TV is only 1080i and not 1080p. I'm still happy though...very good quality! :) I stuck Ironman on it last night and watched some of it in 1080i and then some of it in 720p and both looked fantastic, although i didn't really notice any difference between the two, even though 720p is supposed to be better as it's progressive.
If you get upto the screen really close...it does look a little fuzzy. It's like when you get the black and white dots on your TV but obviously coloured into the picture...but i guess i get this because it's not true HD and it's only HD upscaling. From a distance...it's quality!
All in all, it's a good nice looking machine. If anyone is thinking of getting a new dvd player...i'd recommend an HDMI player...but in particular this one! :)
feck, it looks english but it isn't
does anybody know what stempy said?

No idea! My DVD player cost about £12 from Sainsbury's! LOL Picture looks grand on my £2,000 TV! Ha!!
Perhaps I'd better get a new one....

it looks bad at close distance because it is LCD, mine is LCD too and for that size of screen you need to sit at least 6-8 feet away. LCD TVs reproduce light colour really really well and perform well in room with alot of light coming in whereas plasma tvs produce darks better. You will like notice on your LCD whilst upscaling if a dark sequence in movie can sometimes look like lego as it has difficult producing shades of black.
I watched Hancock on 1080i last night and was superb it struggled on 1080p with some flickering

What size tv do you have Stew? I was gutted when i discovered that my tv isn't 1080p...but the quality in 1080i and 720p is fantastic! Even though i've not really noticed any difference between the two...i think i'd prefer to watch films im 720p...mainly because it's meant to be better than 1080i.
I've not noticed any pixelating to be honest. The dark areas seem to be ok now i'm watching films in HD. It used to be awful...really lego'y before the introduction of HD...so i know what your saying! :th_36_1_211:
46" LCD tv we have EPi and tbh I reckon it is just being that bit too close that we see these things because being at the other end of the room which must be approx 18ft away the pisture is incredible.
Don't know if anyone saw in news this week plasma tv are the latest on the EU hitlist to be phased out along with the lightbulbs.

Yeah if you sit at least 10ft away from the tv the picture looks crystal clear!
Yeah i heard something interesting this morning about plasmas. I didnt actually know that they had to be replaced every couple of years as the plasma inside needs to be replaced! Also, i didnt know you can get "Plasma burn". This happens if you freeze the picture by pausing a dvd or pausing a game. The image freezes into the plasma and eventually can knacker your tv! :?
Most of the time you shouldn't be able to see a difference in picture quality between 1080 progressive and 1080 interlaced, they're both running the same amount of lines, it's only on fast picture movement where the interlaced picture may appear to flicker or get that jagged-edge look on diagonal lines. Progressive scan was designed to eliminate this annoyance.

Indeed mate.
I was disgusted and shocked at the price of HDMI cables aswell! The most expensive i saw were £100!!!! The cheapest were £45 in Currys!!! I ended up getting some for £10 from Argos and they do the job brilliantly! I don't think anyone should pay any attention to the different types of HDMI cables when it comes to components used etc...they all the do same job perfectly well. :-)
Youthe difference in fast motion like a football game where there can be a wee bit of blurring of the players legs.
erm here is one for you to laugh at Epi 2months ago needed to re-route some of the cables that come down from TV to incorporate the bt vision box so decided to cut the aerial cable to put 2 male and female co-axial sockets on. Yes you guessed it and if memory serves Rick and Zap guessed it at the time....McStew cuts the HDBI cable by mistake after painstakingly identifying which one was which but in my defence TV was still on the wall and couldn't unhook cables as hand couldn't access plugs. Anyway I goes to Comet and Currys to find they were out of stock of the lower end cables.....because it needed to be quite long it was costed at £180!!!!!!!!:shock:
Anyway we went without Tv till cheaper HDMI cables came in lol

From what i saw the other night mate i can believe that price! It's ridiculous...and imo just another way to get you to spend more money!
£180 for a cable?!! That's fu**ing outrageous!
£180 for a cable?!! That's fu**ing outrageous!I tell you Phil I was standing in C*m3t and was stunned at what I was seeing. It is almost a case when buying something get an idea of how much it is in your head but in your mind double or treble it before you even leave the house lol
hey guys its at bargain price now :lol:

Monster do make great cables though. I have monster speaker cables on my Hi-Fi gear., bought them years back but they still cost a liver and 3 kidneys back then. Top quality cables come at top prices.

IMO though mate...they all do the same job! I got some £10 Wharfedale HDMI cables from Argos and they do the job perfectly well. I wouldn't want to spend £100's on something which is meant to be "better"...as i would probably see no difference to the £10 cables and then i'd just feel cheated and robbed!

Each to there own really, Unless I had top quality components thoughtout my systems, whether audio or video I wouldnt spend the extra. I have some very expensive HI-Fi gear that is real top quailty stuff so to stick some cheap cables on it could potentially destroy the sound that all that gear gives me. Like all things the quality is governed by the weekest component in the system. It's kind of like you are discovering with the TV and DVD solutions. It's okay having an all singing HD TV but it's only as good as the signal you can supply to it. The reverse obviously applies too, there's not much point in having the latest Blueray player and sending the ouput to a lower quality screen.
I have a Sony 1080p capabale TV but dont really watch films that often and have no intention of going down the HD route until there is more HD content readily available over the normal broadcast routes. It does work a treat with my computer tho' and gives me a rock solid picture.
Sorry to hear you have had some bad news btw.
