HD 1080i vs the 1366 x 768 display & HD ready

and yet more obervations....

The APPLE iTV is already being hailed by the MACheads and Fruit-compute centric crowd, small wonder, but it seems Accenture did some survey that essentially concludes that the iTV type device that turns your widescreen flat 16:9 display and home theater into a more flexible bang for the buck with wireless integration to any other device ( yes read - iPOD, MACbook whatever )... is true and the utlimate desire of the media enabled household. whew.. mouthful that was.



iTunes will deliver 720p downloads in support of this new gizmo. Its all good.

MICROSOFT finally beta'd the Version 11 DRM, thats digital rights management for content. Of course all the screamers launched into a pointless tirade over it, but hey, its like blaming the messenger for the message... all MS is doing is enabling content control for those clients in hollywood that asked for it. DRM is not mandatory in the windows media 11 products, so for it to bother you it has to be turned on for that specific content by the producer of that content... in fact i would doubt that most Publishers of video and music will start using it for some time yet to come, its beta to see what happens.

So if you get some DRM'd WMV or music or video, do not blame microsoft for enabling it, BLAME THE PUBLISHER THAT SET THE FLAGS IN IT... in fact there are abundant levels of control in DRM that allow all kinds of things, its up to the people that create the file and distribute it. If you dont like that, then get your stuff from someone else in some other way, freedom of choice will send the message needed.

The 1366 x 768 resolution screen... I get this a lot
ok here is a practical response without a lot of geekytech words. A lot of nice large 16:9 widescreen flatpanels say High Definition, and the TRUE HD camp says that 1080i requires 1920 x 1080 pixel resolution.

If you feed a 1080i signal into the component YpBPr or HDMI / DVI input of a 1366 x 768 display, then it should look fine, your screen is getting twice as much information digitally as it needs to create a great image. Do Not Worry. I have done this with one of those 37 inch DELL displays, looks great as long as you are sitting a few feet away. What you dont want is a large screen area with 1366 x 768 pixels... 60 inch displays look really fuzzy with that resolution.
In my option however, if you can, get a 1080 display since broadcast 1080i is where its all going.
I have seen and love the Sony SXRD 1080 stuff and Westinghouse LVM 37" and 42" 1080p monitors for price performance.

HDMI 1.3
This is cool, if you encounter a system with HDMI connections, this is where 1080 will be in the future, so ask if its HDMI 1.3 compliant. This has to do with audio On HD DVD and Blu-ray both codecs will boast lossless coding for up to eight discrete channels of audio at resolution at least as high as 24-bit/96kHz. The catch is that the new codecs will only be carried digitally in their native form over HDMI 1.3.

Hi Jeff,

I wanted to email you this, but couldn't find an email address anywhere here.

I just did a rant on Samsung's "HDTV" 27" 4:3 TV on my Computerworld blog.

Was wondering what you think on the subject.

Alex,
Thanks - i do so agree with your observations. The middle-income buyer is the prevailing marketspace, and expecting that customer to grapple all the half-information half-hype marketing is creating a problem.

Interesting that Best-Buy recognizes that, and i would say that each Magnolia/Best Buy i have encountered actually has a person there that knows what the facts are

Do you assist with usable settings for 264 codec to output compressed movies using Quicktime from a 1080i Sony camera? I am lost in producing 480, 720 and 1080 output via the web. Would appreciate any knowledge you could impart.

Have to say...while I get your point, I feel cheated. I'm sorry that I didn't do a little more homework before I stepped in the store this holiday weekend.

Just bought a Sony KDL-46S3000 LCD HD set. Great price. The way the specs in the store read, it implied that the TV was 1080i (specifically, the little placard with the TV info said 480p/720p/1080i).

I am now finding out that the Display Resolution is 1366 x 768, which, from all indications I seem to be reading on the web, is 720p!!!

Clearly, the set is capable of handling all of the above signals from an input perspective (and for that matter, it can handle 1080p input according to what I now know from the owners manual), but the display resolution will NOT be true 1080, i or p !!!

This is wreaks of deception on the part of the retailer.

Shame on me for not having all the info before going to purchase, but still...it's not cool for these places to misrepresent the products like that.

That said, the picture quality of the 1080i broadcasts are very good compared to the standard def pics, or even the 720p broadcasts but that's a given (or at least it should be).

It's not so much the picture quality issue that makes me mad, it's just the priciple of the thing.

Don't make me think I'm getting something that I'm not!!!

Sorry for the rant. Actually glad I came across your page, some great info here. Thanks for sharing.

sorry about me bumping into your conversation butI declare myself a newbee in all this HD business. after reading your posts I can infer, correct me if I'm wrong, a resolution of 1366 X 768 means that the resolution will be 720p? then which is the resolution for 1080p display?

thanks
