What you need is Magnifier
or HDMI output
Last time I checked most 1080i TVs had a resolution just above 720p (768p I think). So did it go from true 720p to 768p then?
What are you talking about. 1080i means 1920x1080i. The only difference between 1080i and 1080p is that one uses an interlaced signal and one is progressive. 768p is 1366x768p.
I would love to hear what source you "checked" though.
LCDs are a static resolution. Look at any 720p/1080i TV and you will see they are nearly all 768p. So the TV has to scale all input signals to the TV's resolution. I highly doubt the device is true 1080i, more that it accepts 1080i now and if it was true 720p before, then it got a slight bump to it's resolution. I have never even heard of an LCD being interlaced.
So I am looking for the devices true resolution, because I know it isn't 1080i.
Actually 1080i is just a simulated 1080 image done on a 720 screen. On the first pass it shows lines 1,3,5,7..... and on the second pass it shows lines 2,4,6,8.... all the way up to 1080. My 1080i HDTV only has a physical resolution of 1366x768.

reiththestud: No, your TV is HD-Ready, not True-HD.
Come on guys. A TV that does 1080i actually does 1080i. Those would be CRT televisions, which (as far as I'm aware) are the only TVs that currently display an interlaced signal as interlaced (CRT projectors included). The first scan is 540 lines in 1/60th of a second and the second scan is a new set of 540 lines in the next 60th of a second (540 lines of resolution in each 60th of a second). A 720p signal contains 720 lines in each 60th of a second. As for conventional CRT TVs, 480i means 240 scanned lines per 60th of a second. Let's not mix up the difference between an input signal and what a display ACTUALLY displays.
superhobo: An HD-ready TV is one which understands 1080i and 720p input signals from component video, DVI, or HDMI. In other words, a TV capable of displaying 720p, 1080i, or 1080p...but one that does NOT have a digital TV tuner (ATSC). Most computer monitors can be considered "HD-ready". The difference is that an "HDTV" has a digital OTA tuner and an "HD-ready" TV has no such tuner.
Furthermore, "True-HD" doesn't mean anything. Some companies call 1080p "Full HD". But the only TrueHD is Dolby TrueHD...which means nothing for video.
My bad, I meant Full HD (was sleepy).
But if what you said about HD Ready is true that means there are FullHD sets that are also labelled HD ready? Haven't seen any. I thought HD Ready meant it could accept 1080p as input and display it as 720p.
1080i is 1080 resolution at half bitdepth since you only get half the information per pass...about the same amount of bitdepth as 720p (all the information per pass)
so 720p = lower resolution more bit-detail
1080i = hight resolution less-detail
in a blind test most people can't tell the difference in anything under 42'' then after that 1080i usually looses. (at normal sitting distance) on LCDs and 1080i wins on plasmas and projectors.
I forgot the source...sorry to not cite but im not pulling this out of my ass.
I'd love this as a second, touchscreen monitor...
Yeah, I thought interlaced resolutions were only for non-LCD type displays. The only reason I could think you would implement it on an LCD was due to processing/bandwidth issues. If you only have 720/768 pixels to work with, what benefit would interlacing offer.
Correct. All LCD displays are progressive. 1080i is essentially 1080p at 30hz. Alternate 540 frames are transmitted at 60hz, the panel creates a single 1080p frame from the two 540 frames.
@Diamamet
No. If you have a 1080p TV, it probably does not simply add the 2 frames together to make a single 1080 line frame...if it does, it probably looks bad. This is what deinterlacing is all about. The second set of 540 lines in a 1080i signal does NOT make a composite picture with the first set. It is a completely new image (unless the source is originally 30 or 24 frames). If the 2 images are simply added together, you get the infamous "jaggies". Any deinterlacing "looks" at both the first and second scans of an interlaced signal and attempts to add the 2 scans where static areas of the picture CAN be added but dynamic areas cannot (again, if you want to avoid "jaggies").
The task with deinterlacing is due to the dynamic areas where information must be created or interpreted.
One can assume, given the price of the previous offering, that the panel on the device will be some kind of low resolution (once again, for the price, probably less than the equivalent archos), yet with HDMI out for hooking up to your tv/pj/monitor. Sounds like a great idea - no doubt it will support all the underhand formats as
The last one: "The B52HD supports RM, RMVB, MPEG, AVI, FLV video" I wonder what they mean by AVI (being just a container and all) - hopefully they offer up some DivX and MP4 goodness on the second rev - if they do, I will be elated at not having to lug laptop and external HD to gf's everytime she wants to peruse my back catalogue of various tv shows...
At what point does increasing the resolution become pointless on a PMP? I'm not sure that people would see much of a difference in 720p and 1080i on such a small screen.
the screen isn't 1080i it OUTPUTS 1080i....learn to read
It's a 5.0" 800x480 screen. 4.3" & 5.0" screens at that resolution are dime a dozen among Chinese players these days.
Wow,
Touchkiller ,,,??
People don't seem to get this. This thing outputs 720p (1280x720) and 1080i (1920x1080 interlaced). I doubt that this screen actually has that many pixels. Digital TVs that only support "1080i" usually are not 1080p native because if they were, they'd advertise it as 1080p. They seem to be able to get away with saying 1080i because their hardware can process it, not because it actually has that many pixels. But the ability to output 1080i means that it actually does output 1920x1080 interlaced. What I am confused about is the fact that 1080i at 60fps seems to have the same amount of data as 1080p at 30fps. Half of 1080p with twice the framerate (540*60) is the same as 1080 times 30. Anyone have a clue?
1080i @ 60fps is only 30fps because you only get half the image per frame
Yes, so why can't a 1080i60-outputting device put out 1080p30? If it's the same amount of data per second, it doesn't make sense why not. Same with cable/satellite services. If they have 1080i, why not 1080p?
Hey, just wondering, how would US and Canadian customers buy this when it is released.
This question will also apply to the B52HD and the Egoman PMP (MP810RSTD-43) they have.
I really looked on ebay, google, there is no way I could find!
Anyone, please help me! Cause let's say it's going to be $80 or something under $100. Compared to an Archos, it's a dealbreaker. Yes, I do know it's 16GB... but who cares, I wouldn't mind plugging it, deleting and addding other stuff and save $300 and more!
Really? My Tavi 030 has supported this for 3 years.
Wow, you know if Engadget geeks like us can't agree on what HD or 1080i means what hope the general public!
1080p is 1920x1080 pixels on any given frame, which equates to 2.0736 MP per frame if you want to use digital camera speak.
1080i is 1920x540 pixels on any given frame, which equates to 1.0368 MP per frame...
720p is 1280x720 pixels on any given frame, which equates to 0.9216 MP per frame...
For video that is the same frame rate, 1080i takes up 12.5% more bandwidth. Now using a good deinterlacer and halving the frame rate, such as 1080i@60fps to 1080p@30fps, you can make a 1080i video into 1080p video. Only then will the resulting video look discernibly better than 720p. Then again 1080p needs 125% more bandwidth than 720p.
In short, the jump from 720p to 1080i is practically marginal depending frame rate. Assuming they are the same, there isn't much of a difference between the two
