On a relating note, Nintendo with their Revolution still! hasn't said whether or not they are making all their games with widescreen by default. Even worse they have confirmed that its games will not be HD (720 or 1080) but only 480p, but if they end up not supporting widescreen with this machine that'll be around for a good 5 years I really think they're shooting themself in the foot. Sure HD isn't yet a big time average household commodity, but its growing hellishly fast and who knows where we'll be by 2010.]]>Apr 25th 2006 7:48PMhttp://hd.engadget.com/2006/04/25/ask-hd-beat-does-480p-and-16-9-really-match/http://hd.engadget.com/2006/04/25/ask-hd-beat-does-480p-and-16-9-really-match/Apr 27th 2006 7:57PMhttp://hd.engadget.com/2006/04/25/ask-hd-beat-does-480p-and-16-9-really-match/http://hd.engadget.com/2006/04/25/ask-hd-beat-does-480p-and-16-9-really-match/
The two worst things to happen to HD are HD Lite and Multicasting. ]]>Apr 30th 2006 11:55AMhttp://hd.engadget.com/2006/04/25/ask-hd-beat-does-480p-and-16-9-really-match/http://hd.engadget.com/2006/04/25/ask-hd-beat-does-480p-and-16-9-really-match/
For starts, what is this 640x480 on SD TV that is being listed? Broadcast SD is 720x486, SD never used square pixels for 16x9 or 4x3. HD is broadcast using non-square pixels as well, but it's also SHOT using non-square pixels. Two main formats for anything shot in HD would be DVCProHD and HDCam. DVCProHD is 1280x1080 in 4:2:2 for 1080i and 960x720 4:2:2 for 720P. HDCam is 1440x1080 in 3:1:1 for 1080i. So, neither will actually give a recorded format of 1920 pixels at all, and chroma will give you far less...chroma resolution would be 640x1080 for DVCProHD and 480x1080 in HDCam.

So yes, not all pixels are square, but also realize that not all resolutions contain full RGB888 resolution, any video broadcast/record format is in a YUV or similar colourspace that subsamples chroma far more than luma.

And to say that HD Lite is a crime is pretty ignorant, since most of the time your HDTV doesn't even have 1920x1080 resolution. Just because it is a 1080i HDTV doesn't mean it has a true effective resolution of 1080i. We were doing some broadcasting at E3 displaying on 42" monitors that were 1024x768 widescreens, no body would have guessed that these were technically "not HD".]]>May 19th 2006 5:59PM
