HDTV 1081p or i and some hd knowledge needed for a noob? What do they mean?
Thanks, Mike.
Answer:
the first thing to understand is the difference between interlaced (i) and progressive (p). with interlacing, the image is displayed in pieces like this
a
b
a
b
the a's would be displayed every 1/60th of a second and the b's every 1/60th of a second. at that speed, the human eye is not able to discern the the separate images. this was done because the original television broadcasts did not have sufficient bandwidth to support sending the entire image at once.
progressive images are displayed in their entirety every 1/30th of a second.
progressive tends to be better than interlaced, but a lot of that depends on the television and the source. 1080p is the latest buzzword in tv sales and you will undoubtedly hear it frequently. in my opinion (and this is purely opinion) i don't think having a 1080p capable tv is worth the extra cost. most people can't tell the difference between 1080p and 1080i unless the tv is huge and they are very close to it.
common resolutions:
480i/p dvd resolution
720 hd
1080i hd
1080p hd
Most tv's will automatically adjust their resolution based on the incoming signal so you won't have to worry about setting that. and then we get into upconverting which is a whole other topic :)
Basically TV is a devices to display a signal that it receive.
So the output is really depend on the source (DVD, BD, HDDVD). Wetter it 720p/i or 1080i/p.
