The war of words continues

It's not uncommon for companies to downplay features that its products don't have in comparison to its competitors. Companies will usually talk about how customers won't likely use the feature or how it's not cost-effective to implement such features at a certain price point. Microsoft has been on the defensive with its XBOX 360 for quite some time. The company has defended its lack of a built-in next generation DVD drive, it has downplayed the importance of HDMI with next generation games and now it is saying that 1080p doesn't really matter in the grand scheme of things.

Andre Vrignaud, Microsoft's Director of Technical Strategy for XBOX Live says that 1080p is mostly hype with the PlayStation 3. He goes on to say that 99% of the PS3 games released will be rendered at 720p while the only ones with 1080x native support will be arcade ports or games that sacrifice in-game effects. Here's a snippet from Vrignaud's Ozymandias Blog:

The PS3 has roughly the same pixel-pushing capabilities as the Xbox 360. Don't need to take my word for it, it'll be obvious soon enough over the next year. Even if this wasn't the case, consider we now live in a multi-platform development world, and that the current sweet spot developers are targeting is 720p due to the extremely similar system specifications. Simply put, a developer who is planning to release their game for both the Xbox 360 and the PS3 will aim for a common attainable ground. In fact, I'll stick my neck out and predict that that you won't see any 1080"x" games for the PS3 this year.

Vrignaud goes on to cite Home Theater Magazine's Geoffrey Morrison as validation for his criticisms of 1080p on today's consoles. Since Vrgnaud notes that 99% of PS3 games will render at 720p, that leaves the argument for 1080p with movies. "In this case, the only difference between 1080i and 1080p is where the de-interlacing is done. If you send 1080i, the TV de-interlaces it to 1080p. If you send your TV the 1080p signal, the player is de-interlacing the signal. As long as your TV is de-interlacing the 1080i correctly, then there is no difference," said Morrison.

One thing to keep in mind about the 1080p NTSC standards:

Unlike 720p, 1080p does not have a 60 FPS mode. 1080p runs in 24 and 30. After de-interlacing, a 1080i signal should equal a 1080p signal. You shouldn't see any difference.

While I am all for improvements in technology (as we all are), I don't think Sony has anything better to offer than Microsofts HDTV support. The buzzword "1080p" is used way too often by people who haven't seen all the formats.

A deinterlaced 1080i video is not the same as a native 1080p video. When the video is interlaced half the data is thrown out. It is gone, never to be found there again. Yes, you could go back to the original, but that is not what you have now. For example. Consider a video where half the scan lines are blue and the other half are yellow and where the color alternates each frame (so first frame will be green, yellow, green, yellow and the second frame is yellow, green, yellow, green and the third is the same as the first). An interlaced video will only pull one of the colors. As a result the deinterlacer will examine the picture, see that everything is the same color, and guess that that is what the picture is suppose to be. Then your flashy green screen turns into a yellow or blue one. While this is an extreme example, it does happen to a lesser extent with normal TV images.

Oh, and we are not talking about the over air transmission of HDTV, we are talking about HD movie play back, so the 1080p30 format does not apply. Also, NTSC does not have a 1080 format. That is ASCL or something like that. Same people, different name.
